After a brief nap and laying in each other's arms, Delilah and I began to wake up. There was still a smell of sex and sweat in the room, but neither of us seemed to mind. As Delilah woke up she was rubbing my chest, then moved her attention to my semi-hard dick. I leaned down and kissed the top of her head. This was a beautiful moment, just the two of us lying in bed together, holding each other. Even the crime of taboo had faded out of our minds.

We lay there for about five minutes before Delilah slid out of the bed and out of my arms. She walked over to the door and put the do not disturb sign up so we wouldn't be bothered in the morning. When she walked back, she reached her arms towards the ceiling and stretched. Her tall frame and muscular body were magnificent and alluring. It was clear, being in the military helped her keep a fit and toned physique. I couldn't help but stare at her as she stretched her body and swayed her hips.

As she moved around I could hear subtle cracks as she moved her body. Seeing her flex and contort was arousing to me and I was almost fully hard. Delilah noticed this and walked back over to the bed. She grabbed my dick and stroked it a few times then planted a kiss on my lips. She tasted like fire, even more so when she slid her tongue into my mouth. She began stroking me slowly as our tongues danced in each other's mouths. Delilah broke away from our kiss and moved her head down towards my dick. She pointed it straight up, right below her mouth. She looked up towards me and smiled. Then she let a large glob of spit fall from her mouth onto the head of my dick. After a few strokes, I was properly lubricated.

Delilah began stroking me more vigorously and returned her mouth to mine. She only broke away one more time to remind me of our prior arrangement. While stroking me she said into my ear.

"Don't cum yet brother, remember, you still have to fuck my ass," she said seductively.

"My dear sister, I haven't forgotten. I'm glad you didn't change your mind," I replied.

She moved and kissed my cheek. I reached around and grabbed a handful of her firm ass and jiggled it. I couldn't wait to enter her tight, firm, ass. I pulled Delilah's cheeks apart and was about to slide my hand in further when she stopped me.

"Uh uh, dear brother, not yet. Let's get into the shower and clean up first. I want to be fresh when you take me."

I couldn't disagree with her logic. If I was going to fuck her ass, I would appreciate it being clean. But to be honest, I was so attracted to Delilah, it didn't make a difference to me. Alas, we climbed out of bed and went towards the bathroom. Delilah's room was quite spacious and the bathroom was no different. There is plenty of floor space and a large glass shower against the back wall. Both of us could easily fit in there with plenty of room to move around.

Delilah reached in and turned the water on. She turned back around and saw me standing there, eyeing her up like prey. She took a few steps towards me and began kissing my chest. She ran her hands all over my body from front to back while we waited for the water to heat up. I put my hand under her chin and lifted it up so she could face me. We looked into each other's eyes and there was a passion, a burning desire. Once we noticed the fog had built up on the mirrors and glass, Delilah paused in her actions. She looked at me and smiled.

"Shall we?" she said.

"Let's," I replied.

Delilah turned to enter the shower when I grabbed her wrist and spun her around. I pulled her close to me and pressed my lips into hers. She wrapped her arms around my neck, jumped up and wrapped her legs around my waist, and pulled me in tighter. I held her up and held her weight in my arms. I began walking towards the shower and she reached back and opened the door. We kissed slowly as we entered the shower and the water rained down over us. As we kissed under the water Delilah began grinding her body against my dick which was now fully hard in between us. Her pussy felt so hot against me. I picked her up and adjusted slightly. I grabbed my dick from underneath and started to put it in when she stopped me.

"No brother, not yet, I want you in me after we get cleaned up," she said.

A small sadness came over me when those words came out of her mouth. I wanted to fuck Delilah so badly in that moment. And the water cascading down her body made her so irresistible. But I just nodded my head and pulled her back closer to continue kissing her. Delilah pulled her head back and motioned for me to put her down and I obliged. When she was on the shower floor she reached over and squeezed some soap onto her loofah. She gathered the loofa up and lathered it to her liking and she began washing me. She started at my chest and neck and went all the way down to my feet. She went over every area slowly and precisely, like she was detailing a car or a showpiece. No part of me went untouched during her washing. Then she had me turn around and repeated the process on my backside as well.

While Delilah was washing my back she paid special attention to my shoulders and upper back. She put the loofa down and began massaging me. She kissed up and down my back as she let the water cascade down, rinsing all the soap away. She reached back and pulled the shower head off and sprayed me down while she continued to run her hands over my body. I'm sure I was clean by then when Delilah put the shower head back. She came closer and pressed her body against my back and wrapped her arms around me. She kissed my back and purred. I looked over my shoulder and saw her pressed against me.

Her arms separated and I felt one of her hands slowly make its way down my stomach and begin venturing further. Delilah kissed my back softly and then grabbed my dick in her hand. With a firm grip around my shaft, we rotated so I was facing the showerhead. The water was hitting me directly in the face. Delilah began slowly stroking me as the water rained down over me. It was a different sensation and I enjoyed it. I could have stood there forever, but Delilah had other plans. She moved her other hand down and was slowly stroking me with both hands. A chill went down my spine because her technique was perfect. She stroked me like an expert, with a great rhythm with the perfect amount of pressure.

I let out a soft moan and felt my knees get weak. While I was slightly shorter, Delilah took this time to talk into my ear.

"Don't come yet brother, you still have to fuck my ass. I want this fat dick in my ass so bad. Please last so you can fuck me and cum in my tight hole," she purred.

I nodded my head in agreement. Letting her know I would hold my nut so I could cum in her ass.

"Good boy, I'm so glad daddy introduced us and I found out I had such a loving caring brother. I can't wait for you to put this fat ass dick in my ass and stretch me out, brother. God damn, I want you so bad," she continued.

I could feel myself getting close to cumming, but I fought through it. I had no intentions of disappointing Delilah in any way. If she said she wanted me to fuck her for a week I would have done it. I fought through her dirty talking and two-handed strokes for the better part of ten minutes before she stopped.

"Are you ready dear brother? Are you ready to slide that fat dick in my ass?" she asked.

I nodded my head again as I moaned when she released me from her grasp. I was so ready to fuck Delilah again, I was about to burst. My dick was throbbing and I needed to put it into something. Delilah turned around and was facing the showerhead and about to turn off the water when I had a moment. I grabbed her hands from behind and interlocked our fingers. I held her hands up above her head and kissed her neck and shoulders. I placed several kisses on her and she began to purr.

"Mmm, Patrick, that feels so good. Your lips make my body feel like it's on fire," she purred.

I continued kissing her backside then I stopped. I took her hands and pressed them against the wall. I placed my palms on the outside of her hands. Then I reached up and put my hand under her chin. I pulled her face up so it was right in the spray of the shower. I leaned forward until I was right by her ear.

"Don't move, I want you right here facing the water. Do you understand me? I said in firm, commanding voice.

Delilah nodded her head in agreement. But that wasn't good enough. So I gave her ass a smack.

SMACK!!!

"I said do you understand me?"

SMACK!!!

"Yes sir, I understand. I won't move from this position until you say so, I promise," she said in a slight gurgle.

"Good, now raise up so you're on your toes and brace yourself," I barked.

Delilah leaned forward and I could see her calves flexing. Her legs were muscular and well-defined. I wanted to slip inside her ass right there but I decided to hold out. I knelt down and my face was right at her ass. I took this opportunity to plant some kisses on her ass cheeks and the back of her thighs. Delilah moaned in pleasure from the sensation of my sensuality. But this was short-lived. I grabbed her hips and pulled her back towards me. I took my hands and spread her ass apart letting the water cascade down her back and into her asshole. Her tight hole looked so inviting and delicious. I leaned forward and began licking her ass as I pulled her closer to me. I buried myself in Delilah's ass as I feasted on her brown tunnel.

She tasted just as good from this hole. I began moving my tongue in circles and licking up and down. I wanted to taste every juice she had to offer. Delilah was certainly enjoying my performance as she moaned with each lick. I massaged her ass cheeks while I kept them spread. I felt her almost slip a few times during my anal assault due to the wetness of the floor. I took this moment to get a better angle. I grabbed her left ankle and placed it on my shoulder. This gave me better access to her hole and let me put my face deeper in her ass. Delilah moaned loudly as I continued licking her and massaging her cheeks.

I wanted to send her over the edge so I grabbed her cheeks forcefully and spread them without trying to hurt her. Then I gave Delilah a nice treat. I shoved my tongue up her ass as far as it would go. I swirled my tongue around the inside of her ass and tasted her. My tongue swirled around her wrinkled hole and she was loving it. I felt her go weak in the knees and I loved every minute of it. I can't remember how long I tongued her ass but it wasn't enough for my liking. Delilah moaned and slapped the wall in ecstasy as an orgasm rolled over her. Her hands slid down the wall slightly in pleasure before she put them back up. She must have thought I wouldn't notice, but the streaking sound from the slide gave it away.

SMACK!!!

I gave her a nice hard slap while I was still tongue-deep in her ass. Delilah let out an audible yelp. I pulled my tongue out of her ass and questioned her.

"Didn't I tell you to keep your hands up on the wall?" I growled.

"Yes sir, I'm sorry, it won't happen again," she whimpered.

I was ready to move forward. I stood up and pulled Delilah away from the wall. I reached forward and turned the water off. We stepped out of the shower and began drying each other off. I was very slow and deliberate while drying Delilah. I slowly brushed the towel over her body. Touching and appreciating every inch of her body. After we were completely dry I wrapped the towel around Delilah. I tucked it in right about her chest and scooped her into my arms. She looked into my eyes, ready for what was about to happen next and leaned up and kissed me deeply. I carried her to the bed and placed her down gently. I undid the towel and slid her to the edge so her legs and feet were hanging off. Delilah paused for a second and pointed.

"Top drawer under my panties," she said.

I went to the dresser and opened the top drawer. There it was right underneath her panties. A bottle of lube, I grabbed the bottle and closed the drawer. I walked back over to Delilah, she had a wanting yearning look in her eyes. She was ready and so was I. I pushed Delilah's legs up slightly towards her chest, then I popped open the top of the bottle and applied a generous amount to my dick. I covered my head and shaft liberally to make the entrance as smooth as possible. I squirted an extra glob on my hand and applied it to Delilah's ass. I slowly began working my fingers inside of her, first one then two. When I began sliding the third finger into her, I held them there for a moment. Letting her adjust to the sensation.

During all this, I just watched Delilah moan and lick her lips with each plunge of my fingers. Her eyes rolled and she groaned with the sexiest look on her face. After about fifteen minutes of anal fingering, Delilah was warmed up and ready. I wiped my hand off on the towel and reapplied the lube to my dick just to be safe. I placed one hand on my dick and the other grabbed one of her ass cheeks and spread it to give me easier access. I placed the head of my dick against her entrance, giving her one final look in her eyes. Delilah nodded in approval and I began to slowly slide inside of her. In unison, we hissed at her tightness and grip.

I paused momentarily once the head was in. Then I began slowly sliding inch after inch inside her. After about three inches I let go of Delilah's ass and grabbed her hand. I let her squeeze my hand for comfort as I leaned down to kiss her. I stroked in and out of her with three or four inches, letting her adjust to the sensation.

"Ugh, Patrick, it feels so good. I can feel myself opening up. It's so tight and hot, I love it," she said.

I leaned up further and kissed Delilah on her forehead as I worked my way up to about six inches inside of her. I increased my pace and was stroking her at a good rhythm at this point. I pushed her legs to one side and had most of my dick inside her. Delilah began developing sweat around her forehead and on her chest and neck. I leaned forward and licked it off. Fucking her from the side let me hit different angles inside of her ass. Delilah turned her face away from me as her eyes rolled back and she licked her lips. All she did was moan and groan in pleasure as I stroked deeper inside of her.

Delilah's ass was heavenly, it was so warm and tight. I didn't want to ever pull out. I anally fucked her from the side for quite some time before I decided to pull out and give her a break. She was doing so good I felt she deserved a break before we changed positions again.

"I'm going to pull out okay, take a breath as you feel me moving away."

I slowly moved my hips back as I pulled out of Delilah. My dick made a small plopping sound when I finally got the head out. Delilah let out a small sigh of relief once I was completely out of her. I took a step back and watched her as she laid on her side, breathing slowly with her eyes closed. I went to the bar and grabbed her glass and put some ice in it. I grabbed the bottle and poured a drink for her.

"Patrick, make it a double," she said.

I walked over and placed the glass by the nightstand. I put my arms underneath Delilah and moved her up to the top of the bed with her head resting on a pillow. I handed her the glass and let her rest. I slid into the bed behind her and caressed her body, spooning her. I pressed my chest against her back and her skin was hot. I wrapped my arm around Delilah as she sipped her drink and regained her breath. I kissed the back of her neck and shoulders and just enjoyed the moment. After cuddling for a while, Delilah placed her drink on the nightstand.

"Patrick, I'm...
