After I graduated high school, my dad gave me two options, either I go to college or join the military. I chose the latter and served four years active in the US Army.

When I came back, I had nowhere to go and crashed with him until I found my own place. By that time, he had already married another woman. She had moved in with her daughter.

Because of the time difference from where I was stationed, I couldn't sleep and was up in the kitchen reading a book. Sandra, my step-sister, came in, wearing one of my button-down shirts. "Oh... hi!" she said, startled. "I didn’t know you were in here."

"Hello!" I responded, looking up from my book. "Didn't mean to scare you."

The shirt was only buttoned halfway up and I could see her cleavage. She turned on the stove, filled the tea kettle with water, and placed it on the fire.

"You're up late?" she observed as she opened the cabinet, looking for a mug.

"I could say the same. There's a twelve-hour difference between where I'm from and here. I'm usually up at this hour. What about you?"

"I couldn’t sleep. So, I figured I'd make some tea to help. I... can't... seem... to reach... my mug," she stuttered as she leaned over the counter, trying to reach up for the mug.

She stood on her tiptoes reaching to grab the mug at the top shelf. The shirt had pulled up exposing her ass. I smiled at the sight and licked my lips. She had a nice round ass and thick firm thighs. My dick twitched in my sweatpants as I stood up to help.

"Could you..." she turned to ask me for help. One boob had fallen out of the shirt exposing her nipple. They looked like dark chocolate Hershey's kisses. I gasped at how round and perky they were.

She noticed where my eyes were and followed. Now it was her turn to look. Her eyes shot straight to the outline of my cock through the sweats pants. She licked her lips and smiled.

Our eyes met and we could feel the sexual tension between us. "Fuck it," I said, reaching for her. Our lips smashed as we kissed. I picked her up, placed her on the counter, and started making out with her while grabbing her breasts. They were big and soft.

She opened the shirt all the way as I kissed my way down her chest. I slid my hand down her stomach as I sucked her dark nipples. She laid back and spread her legs. I dove right in and ate her pussy to orgasm right on the kitchen counter.

After her orgasm subsided, I picked her up and carried her to my bed. Since she took my bedroom when she moved in, I was crashing on the pullout sofa bed.

"No, no... my room," she quickly said before I put her down.

She was on all fours on the bed as I pulled my pants down. She gasped at the full length of it. She grabbed the base and placed the head in her mouth. Since it had been a while since the last time I had sex, I came quickly into her mouth.

She laid on her back with her legs wide open, presenting herself to me. I aimed my cock between her thighs, pressing the head at her entrance. Her pussy was drenched. I looked up at her.

"Please," was all she mustered out.

I wasted no time pushing my full length inside her.

"OH FUCK!" she moaned, her hips bucked as the head parted her lips.

I looked her straight in the eyes as I slowly began thrusting in and out of her. I paused once I bottomed out in her. She wrapped her legs around my waist and mouthed, "Fuck me!" That was all I needed to hear as I pounded into her.

Another orgasm hit her hard. Once she came down, I rolled her onto her side and plunged even deeper into her. She placed her palm against my legs, trying to stop me from going deeper. I grabbed her arm and pinned it behind her back as the head of my cock knocked on her cervix.

Within no time, another orgasm came crashing down on her. Her body was trembling. So, I paused and waited for the waves to pass. Then I rolled her onto her stomach. Grabbing her hips, I pulled her ass up. Her body felt like a rag doll. With her face down, ass up in the air, and on her knees, I pushed in all the way with no limits.

With one hand on her back and the other kneading her breast, I fucked her deep and hard. I clenched a fistful of her hair and pulled her up. My other hand grabbed her ass cheek with my arm on her lower back. I pulled her toward me as I pounded her from behind. Her lips wrapped tight around my shaft as I pistoned in and out of her.

Another orgasm crashed over her. Her pussy turned into a pulsating vice grip around my cock. I couldn't take it anymore and exploded right up against her cervix.

As we both came down from our orgasms, I collapsed on top of her with my cock still twitching inside her pussy.

"I came inside you," I whispered in her ear.

"Don't worry. My mom put me on birth control since I started dating in high school."

"Good to know. Because we're going to be doing this a lot more often."

She didn't respond and just nodded. Once she fell asleep, I went back to the living room to sleep.

The next day I was awoken by her.

"Your dad and my mom already left for work," she said with a big smile on her face. I looked down to find her fully naked on top of me.

We spent the whole day fucking, started on the couch, then moved to the bathroom, and in the shower. We had each other for breakfast in the kitchen. Then she took me to our parents' room and begged me to fuck her ass right before they came back from work.
