I didn't make much of an attempt to follow Kay's instructions. On Tuesday, after her visit to the office, I had no interest or need to go out and find someone to sleep with. The next day I went to a bar frequented by business travelers where I thought it might be easy to find some lonely career woman looking to have a fling. I sat at the bar and made half-assed attempts at conversation with a few ladies. But we mostly just chatted about work. Some of them might have been up for something more, but I didn't make any attempt to be bold. I didn't even try to steer the conversation to flirting.

Thursday was hectic and after work, I thought it would just be best to go home, think about Kay, and get some rest for the next night. Sex with Kay is always a marathon session. And she'd mentioned going to a party. With, Kay, that always meant entering into a weird world of booze and sex with people ten years younger than me.

Being with Kay is like having an addiction. I guess you could argue that sex, in general, is addictive, but it's something different with Kay. I don't know if it's the way she always keeps you at arm's length. Or just that it's an adventure and you're never quite sure what will happen. Nothing seems outside the realm of possibility.

Just knowing I was going to see her had me worked up and distracted on Friday morning. I felt like an infatuated high school kid. There was no chance of achieving much at work. By lunch, I decided to exercise a bit of the freedom and privilege that came with my new title and tell everyone I would be working from home for the day.

I was getting a hard-on at my desk from just imagining what might happen that night. I knew Kay didn't have any classes on Friday afternoon - and her roommate did - so I hoped I could drop by and we could spend the afternoon fucking like animals on the living room floor. My cock was throbbing with anticipation by the time I got in my car.

I tried giving Kay a ring as I drove to her house, but her phone went straight to voicemail. It dawned on me that she might be out running errands or have some other appointment. Or be out with friends. I decided to keep driving to her place. Although I realized I was so worked up that I might end up jacking off in the driveway if nobody was home.

When I pulled up I was relieved to see that Kay's car was there. So was Lacy's.

I went up to the porch and knocked on the door. There wasn't a bell to ring. Nobody answered so I tried the knob. It was unlocked.

I stepped in and shut the door behind me. And I was greeted by the sound of what sounded like hammering. It was a rhythmic banging of wood that echoed down the hall. And then I heard the distinct sound of a man grunting. And I knew people were having sex.

I flashed back to the first time I'd been to the house. I'd come through the front door to discover Lacy and her boyfriend fucking in the living room.

I wondered if history was repeating itself.

Or if this time I had walked in on Kay.

I started across the living room. There was a trail of clothing down the hall. Men's slacks. A tie. A dress shirt. There was women's clothing mixed in. Dark slacks and a sweater. There was a pair of boxers and a woman's bra.

I didn't recognize the specific items, but I knew they were Kay's. The bra wasn't large enough for Lacy. And the clothes were professional. Lacy's entire wardrobe had a laid back hippie vibe.

Before I reached the end of the hall, I knew the noise was coming from Kay's room. I walked right past Lacy's door. I could hear Kay moaning. And then the familiar sound of her building toward an orgasm.

Her bedroom door was ajar. I approached quietly and looked in.

Kay was completely naked. She was on her knees and grabbing the headboard. Her hair was down and her body glistened with a light coat of sweat.

The guy was skinny, dark-haired, and in his mid-twenties. He had the thickest cock I'd ever seen. It seemed out of place on someone so slight. And it was buried in Kay. I could see it stretching out her furry little pussy. He had his hands on her hips and was fucking her with everything he had.

"Fuck me. Fuck me!" She kept pleading.

Her voice was getting higher with every word. I knew she was close to cumming.

I stood frozen. I just stared at the two of them. It took me a second to realize I knew the guy. It was Marv. A young guy who worked in HR at the office.

I felt a hint of anger. And I felt jealous, even though I had no right. My stomach turned. I thought I should just quietly leave, but I couldn't force myself to turn away. I just kept watching them.

Kay kept telling him to fuck her harder. Somehow, Marv found another gear. It didn't even seem possible. He crammed that fat cock into her open gash again and again. It was like watching a porno in person. My cock started to twitch.

They were oblivious to my presence. Kay's body rocked back and forth as Marv drove his dick into her. Her tits swung back and forth. She tossed her head and swung her hair around. He slapped her ass firmly and left a big, red handprint. She yelled with delight.

"Fuck me. YES! Fuck me!" Her voice had gone from high-pitched to a husky growl.

"You're such a whore," he growled back. "You're like me fucking you like a cheap slut."

My hand went to my cock. It was rock hard. Again, I thought I should leave. But I could tear my eyes away. I couldn't get my feet to move. A mix of anger and hurt was boiling inside me. And a desire to charge in and shove Marv away and take his place inside Kay.

"OH! Don't stop. Don't stop!" Kay said breathlessly. She pulled one hand down from the headboard and frantically rubbed her clit. And then I watched her climax. She kept telling him not to stop as her body shuddered. She moaned with pleasure as the orgasm subsided. Marv slowed up but still kept sliding his cock in and out of Kay's gash. After a few seconds, he pulled out and rubbed his glistening wet dick along Kay's ass.

"Nooo..." she said. "I want more."

Marv didn't need any coaxing. He put his big boner back in Kay's pussy.

She moaned with delight. She started rocking her hips back to take him deeper inside her. Then she suddenly stopped.

"Are you just going to stand there like a pervert?" she said. Neither Marv or Kay had even glanced in my direction. But I knew she was talking to me. And there was a hint of anger in her voice. "Why don't you close the fucking door and leave? This isn't a show."

My jaw dropped. I didn't know what to do. I couldn't speak. I started to take a step backward.

"Yeah, bro," Marv said. He didn't even look at me.

"Either get in here or get the fuck out. Don't just stand there like a statue."

I didn't know what to do. My feet were frozen to the floor. Kay turned her head and looked directly at me. Her eyes locked on me.

"Yeah," she said. "Get in here or go. Your choice."

She flashed a quick smile and winked at me. And I knew right away that she wanted me in the room. And that leaving might mean the end of whatever relationship we had. I could walk away humiliated. Or I could join in. There really wasn't much of a decision to be made.

I took two steps into the room. And I pushed the door shut behind me. Kay reached back and tapped Marv on the leg and he pulled his dick out. It made a wet popping sound. She crawled to the edge of the bed nearest me and stood up on her knees with her arms extended. I quickly took the last couple of steps to meet her embrace. I wrapped my arm around her sweaty body. She held me tight and slid her tongue into her mouth. Then she started opening the buttons on my shirt.

Marv's cock wasn't long. Just extraordinarily thick. And it was standing out straight in front of him, still soaked with Kay's juices. He seemed confused about what he should do for a moment. He watched her cast my shirt on the floor and then pull my undershirt over my head. I kicked off my shoes while Kay fumbled with my belt. My pants fell to the floor.

Marv finally started moving. He slid up behind her on his knees. He started touching her hips and laid his cock in the groove of her little round ass. His hands wandered up her torso and to her breasts. He started kissing her bare back, even as she leaned into me and kissed my lips and cheeks.

"I'm aching to cum," he said. He spread her thighs with one hand and put the head of his cock in her pussy lips.

I shook my head.

"No," I said out loud. "That's mine."

Kay flashed that wicked little grin again.

"I like it when you take command," she said.

It was often easy to forget that she was ten years younger than me. She seemed so much more comfortable than me in sexual situations.

I dropped my boxers. Kay's hands went quickly to my big hard cock and she gave it a squeeze and a couple of tugs. But it didn't need it. I was already as hard as a rock.

"That pussy is mine," I said.

They both slid back and made room for me in the bed. Kay stayed on her knees between the two of us. She took a cock in each of her hands. She gave Marv a slow kiss while he cupped her left breast. I grabbed her right tit and then she turned and kissed me. Her tongue snaked its way into my mouth. I slid my hand down her flat stomach and curled my middle finger into her dripping wet cunt.

"Make me cum," she whispered.

I pumped my finger in and out while my thumb pressed on her stroked her clit. Marv and I each kissed her neck and tits. He gripped her ass and tickled at her asshole while I fucked her with my finger. Kay started to moan and wiggle between us. She pumped both of our cocks up and down with her hands. She was jerking Marv harder than me. Almost like she wanted to finish him off and focus on me.

I put a second finger into her tight little box and started fucking her forcefully. I kept my thumb circling her clit. Marv was just fonding her tit and rubbing her stomach. He was groaning hard. He was about to erupt.

Kay squeezed my cock firmly with her right hand and started to squeal. Her left hand stopped moving - leaving Marv very close to the edge. And then she came hard. She clenched her thighs and pussy on my hand. I kept touching her clit as her body shuddered.

She let it pass through her, and then she pulled away from me. She plunged her head down onto Marv's prick. Her ass was facing me. Marv gave me a little nod.

"Fuck her, man,” he said.

I buried my cock inside her hot wet hole.

Marv's eyes darted back and forth from her lips on his cock and my dick spreading her pussy open.

"This is so fucking hot," he panted.

Just being inside Kay made me want to shoot my load. But I was able to hold out.

I slid my big dick in and out of her velvety pussy. It felt perfect. I watched Kay work Marv's cock. She tugged on it at the base and slurped on the head. He started moving his hips - forcing that fat prick inside her. I tried to match his rhythm. Every time he pulled out, I slid into Kay from behind, nudging her forward and down his cock. I pulled back when he crammed his rod back down her throat - causing her hips to rock back and down my shaft again.

We went back and forth slowly for a few seconds, but Marv couldn't hold out. He needed to cum. He started moving faster. As he sped up, Kay tugged harder on his dick. And I started pounding her from behind. Kay grunted every time I buried my dick inside her. She moaned and groaned with a mouth full of Marv's fat dong.

He couldn't hold out any longer. He pulled back and his dick slipped from Kay's lips. She gave him a few final tugs. And then he popped. Cum oozed from the head and ran down his thick pole. And Kay enthusiastically licked it up with the tip of her tongue.

Marv collapsed in a heap on the bed. He was trying to catch his breath. Before his cock could even get soft he started stroking it again - desperate to get back in the game. But I wasn't about to wait for him.

I pulled out long enough to get off the bed and stand at the edge. Then I grabbed Kay's narrow hips and pulled her to me. I slid my cock back in her sloppy wet twat. I wrapped my hands around her thighs and pulled back hard and pushed my cock all the way in. Kay cried out with delight.

"Give it to me!" she said.

Standing up, I could get more thrust. And I attacked her pussy with no mercy. The room was filled with the sound of our flesh slapping together. I pulled her back to me every time I grunted and thrust into her. She was so wet that it started to make a squishing sound.

Marv moved closer to Kay. He tried to put his semi-erect cock on her lips, but she couldn't focus. She grunted and yelled and I just fucked her harder. She got louder and louder - and that only made me go faster. I wanted her to cum harder than ever before.

"Rub your clit," I commanded.

And she obeyed. She frantically rubbed at her clit and tried to balance herself on one arm. She called out my name. And then it hit her. Her whole body started to quiver. She screamed with pleasure. I felt her pussy tighten around my cock. Her juice ran down my thighs.

Kay pulled away and rolled around in the sheets. She made a sound of sheer pleasure. Then she turned and looked at me with eyes that were full of animal lust.

Marv slid between her thighs and lined up to fuck her again, but she quickly shook her head.

"No, no," she moaned. "I'm too sore."

His dick was rock hard again and he looked disappointed.

"Come here," she said.

Kay rolled onto her back and Marv knelt to her left on the bed. She pulled his cock to her lips again and licked it up and down. She wagged a finger in my direction, and I knelt beside her on the right. My dick was throbbing. She looked left and put her lips around Marv's fat head. She bobbed up and down a bit. Then she started jerking his wet cock. She looked at me and then pulled my cock to her lips. She wrapped her right hand around the base. She started jerking the two of us. The tips of our cocks were inches apart, and Kay would turn from left to right and back again - taking a few seconds to suck on each one. She kept pumping her hands on both shafts. Marv and I were both groaning with delight.

"This is so fucking hot," Marv repeated again.

"I love your big cocks," Kay said in her best porn star voice.

She paused to bob her lips up and down Marv's pole.

"Two big cocks both hard for me!" she said.

And then she ran her tongue around the tip of my dick.

She started pumping both cocks faster.

"I want you to cum on me," she said. "I want you to cum FOR me," she said. "I want to make you cum."

The bed started rocking back and forth from her jerking us. Kay's titties bounced up and down. I couldn't take my eyes off them. She tickled the very tip of my cock with her tongue. Then she turned and did the same to Marv. He let out a long, low groan.

Marv grabbed the base of his own cock and started tugging. Kay kept her hand higher up. She sucked the head and let her spit slide down his pole.

She turned and wrapped her lips around my cock again. She swirled her tongue and tugged fiercely. I was ready to blow.

"I'm gonna blow," Marv said.

He gave his thick tool a final hard jerk and his cum shot out onto Kay's titties and ran down her hand.

I tugged the base of my own cock. Kay had her hand around the middle and her lips over the tip. I felt my balls pull up tight. My dick spasmed. And then I started unloading in her mouth. I pulled back and my jizz landed on her neck and tits. She ran her fingers through it and mixed it with Marv's. She brought her hand to her mouth and licked it clean.

The three of us lay there on our backs not talking. We were all trying to catch our breath. Finally, Marv broke the silence and mentioned he had plans for the evening. Kay got up and wrapped herself in a long, white dressing gown. Marv dressed and she walked him the front door. When she came back, I was still completely naked on my back in her bed.

In the vintage robe with her hair down, she looked completely eloquent. Like an old movie star. It was an image that was totally out of character from who Kay actually was.

She came to the bed and laid down next to me. She put her head on my bare chest. She gazed up at me with those beautiful brown eyes.

"You OK?" she asked.

She looked genuinely concerned.

I nodded.

"Are we OK?" she asked.

I didn't know what "we" meant. We had something between us. The only problem is that Kay was the only one who actually understood our understanding.

I nodded again.

"You know it wasn't on purpose, right?" she asked. "I had no idea you'd come by early. I didn't expect you to walk in on us. It wasn't planned."

"I know that now that you've said it," I said. "I wasn't sure before. It seems like maybe you've wanted something like that all along."

"Yes," she responded. "I definitely have. But I'm not going to trick you into it. I'm not going to force you."

"OK," said.

"It feels like you're upset. Or hurt," she said.

I nodded.

"I am," I said. "But I know I have no right to be."

"You have a right to your feelings," she said. "I trust you. I know you're not going to be irrational or immature about things."

She sat up and threw a leg over me. She straddled my thighs. And then she pressed the silk of her robe over my semi-erect cock.

"Can I take your mind off it? I know how to make you feel better," she said.

Her fingertips slid up and down my shaft through the thin silky fabric. She moved slowly. She teased my cock.

"I thought you were sore?" I asked.

She nodded.

"Maybe I exaggerated a bit," she said. "Maybe I just wanted to get you alone."

She smiled provocatively.

"You might have to go slow," she whispered.

She slid up my body until her furry slit was pressed against my cock. It was like a hot dog in a bun. And she kept rubbing the other side of my shaft through her silky gown. Trailing her fingertips gently up and down.

"Can you feel how wet I am?" she asked.

I nodded. My cock was turning to granite.

"I need you," she said.

I just nodded in response.

"But you have to be slow. Can you be slow?"

I nodded again.

"Can you fuck my wet pussy nice and slow?" she asked. "Can you handle that?"

I nodded again.

"But I'm so wet. I bet my pussy feels so good. Are you sure you can take it?"

She tickled my cock head gently. I could feel the heat of her pussy on the underside of my shaft.

Kay pulled the sash on her robe and it dangled open. She looked sexy as hell. Her luscious breasts were perfect. Her brown nipples were erect.

She rose up just a bit. She put the head of my cock at her spread gash.

"No," I said.

"You don't want it?" she said with surprise.

"Not like this," I answered. "Grab the headboard."

She smiled and got off of me. She shrugged her robe off. She grabbed the headboard and poked her tight little ass back into the air. I grabbed a cheek and gave it a firm squeeze.

"You gonna fuck me the way he did?" she asked.

"I'm gonna fuck you better than he did," I said

She smiled.

I got behind her and grabbed her narrow hips. My cock was completely rigid and pointing straight up. It was easy to slide it right into her slick hole.

"Mmmm," she said. "Go slow. Fuck me nice and slow, baby."

I pulled back out slowly. I watched as my cock came back out glistening with her juice.

She groaned as I pushed it back in. And then I pulled it out slowly again. I leaned up so my bare chest was pressed against the flesh of her back. I slid it in slowly again. I pulled it back out. And then in again. She felt so good wrapped around my dick. It was agony. I was aching to jackhammer that tight pussy. But I kept working it in slowly. The two of us moaned in unison. It was different than the way we normally fucked. But just as intense.

"You like that, baby?" I asked her. "You like this cock inside you?"

"Oh, yes," she panted.

I pulled back and gave her a couple of quick pounds.

"Oh. Oh!" she yipped. "Be gentle," she pleaded.

"I don't want to be gentle," I responded. "I wanna fuck you hard."

But I kept going slow. I reached around her waist and put a thumb on her clit. I circled it and toyed with it while I kept dragging my cock out and pushing it back with slow precision.

Kay started to whimper with delight. I moved my thumb faster on her clit. I grabbed her left tit with my free hand. I cupped it so the nipple was between two fingers. I gently closed them like scissors and squeezed the nipple. Each time I slowly slid my boner in, I squeezed her nipple and flicked her clit. I pulled out and released the nipple. Then thrust and squeezed again. I worked Kay into a frenzy.

"I'm going to cum, I'm going to cum," she panted. "Fuck me hard right now."

But I didn't listen. I kept going just as slow. I only moved my thumb faster on her clit. She started breathing hard. I buried my cock all the way in her and held it there. I rubbed her clit frantically. I gave her nipple a slight twist. And then she let go. She started bucking back. She pushed into my cock. I grabbed her thighs with each hand and held her tight on my shaft while her pussy fluttered. I felt her clenching and releasing on my cock. I held her until she was finished. And then I slowly slid my cock out.

"Where are you going?" she said.

She turned back to look at me and her eyes were wild with desire.

"You're not finished," she said. "I'm not finished," she added.

I grabbed her hips again. I put my wet cock on the crack of her butt. Then I pulled back and put the head right at her asshole. I started pushing it in.

Kay gasped.

"Now I'm going to fuck you hard," I said.

Kay just nodded and grunted. She could barely make words as I worked my cock all the way in her back door. I didn't stop until my balls were against her flesh. I started fucking her slowly.

"Yessss..." Kay gasped through clenched teeth.

I reached around and curled a finger into her cunt. My thumb found her clit again. I fucked her with my finger and cock at the same time.

Kay couldn't say a word. She just moaned and groaned. I sped up. The bed started rattling violently. The springs squeaked. The headboard cracked the wall. Her tits shook violently. And Kay whimpered and moaned.

My finger pumped in and out of her pussy. I toyed with her clit. And I slammed my cock into her ass again and again. It was tight and hot and I knew I couldn't last long. Our flesh came together loudly with each thrust. Kay's voice got higher and higher. I grunted and panted and fucked her harder. I worked her cunt with my hand. I wanted her to cum. I wanted her to cum and then I was going to blow right after.

It only took another minute. Kay started to climax again. Every sound she made was unintelligible. I kept fucking harder while he came. I was so close. I felt my cock twitch and I pulled out.

My hot jizz sprayed out onto Kay's smooth ass cheeks. I shot again and again and cried out at the same time. Kay finally let go of the headboard and collapsed on her belly in the bed. I moved to her side. Again, I found myself on my back just trying to catch my breath.
