"James, I'm bored," whined my 16-year-old stepsister, Kimmy, on a Saturday afternoon. Her mum and my dad had gone away on an anniversary trip. Leaving me in charge. No 23-year-old wants to babysit their stepsister.
"You are always bored," I said with a roll of my eyes. "Look, my dad and your mum specifically told me not to let you get into trouble or leave you alone. They gave me some money to take you out for dinner or anything."
"Fine," she sighed and flicked a strand of her long blonde hair behind her shoulder. "I wouldn't mind going to see a film."
I opened my phone to see what our local cinema was playing. "The only ones playing this time of night are 18s. Think you could get away with being 18?"
She shrugged a shoulder. "I don't know. Maybe."
"Better idea. Get dressed up. I'll take you as my date. We'll go to a different cinema, so no one will know us. You'll probably get in better that way. What do you think?"
"All right. I'll go and get ready. Got to look like we are on an actual date and it is an excuse to dress up for the night."
I was going to drive us to the city. We lived in a small town, where everyone knew everyone. So going to the city for the evening was the best for the both of us. Particularly to get her into an 18 film. The problem with my stepsister is that she does look younger than 16. But that changed when she came downstairs. She had curled her blonde hair and wore a little make-up. But her dress made her look older than 16. It was a strapless, short black dress and she wore red heels with them. It was wrong but I was attracted to her. "Wow! You look... older than 16."
"That is the plan." Walking past me to leave the house. "Best get going."
I looked at her ass. I couldn't help myself. Glad I did to be honest. What an ass on her! I quickly adjusted myself in my trousers. Damn my sex-starved brain.
The drive was just over an hour. She put music on while I concentrated on the road. But it was hard with her in that dress. Her smooth legs on show. If she were a real date, my hand would be on her thigh, touching her. I kept my hands tight on the steering wheel of the car as I pulled into the car park. We got out of the car and began the short walk towards the cinema. "Hey, we're supposed to be on a date," she said with a laugh.
"Come here." I wrap my arm around her shoulders and she wraps her arm around my waist. "You owe me," I whispered in her ear as we walked into the building.
She put her other hand on my chest and whispered back, "I will. I promise."
Our ruse worked. We got her in. The cinema was nearly empty. Mainly other couples on an actual date. The film started and it was a loud action film. It was good until a very steamy sex scene came on. The other couples started kissing and more than likely touching each other. I glanced over at my stepsister and she was rubbing her thighs together. My hand was itching to touch her and help her but I knew she would freak out. I looked up at the film to see the woman riding the lead actor. My own cock hardening at the sight of her bouncing. I couldn't help myself. I rubbed myself through my trousers, hoping it was dark enough for Kimmy to not see.
I watched the scene intently until I felt a hand on my hand. "Let me," she whispered and pushed my hand away. Her hand gripped my cock through my trousers and rubbed slowly.
"Oh fuck," I whispered. I had to touch her too. I reached over to her and placed my hand high on her thigh. Rubbing her soft skin slowly and pushing my hand up the skirt of her dress. My fingers touched her underwear, she was soaked. I rubbed her slowly. Her hand moved harder over my covered cock. "Fuck," I whispered out a moan as she unzipped me and pushed her hand inside my trousers. Her small hand gripping me as much as she could. I turned my head to look at her. She was covering her mouth with her other hand. Using my free hand, I pulled her hand away and pulled her into a kiss. She didn't stop me. I kissed her and rubbed her harder over her panties. She moaned against my lips as she came. Her panties very wet now. "Let's go." I said pulling away from her mouth. She nodded silently. Unable to speak.
We left the cinema quickly. This time a little differently. We didn't have our arms around each other. We rushed to the car. Once inside, I grabbed her and kissed her hard. "This is wrong," I moaned as she put her hand on my crotch.
"I don't care anymore." Rubbing me quicker. "I don't think I can wait to get home." Pushing her skirt up for me to see her black thong.
"There's a hotel," I nodded in the direction of the Premier Inn.
We left the car quickly and rushed into the hotel. The receptionist didn't ask us anything, just gave us a room key and told us where to go. I pulled her into the lift and kissed her hard. We had forgotten we were stepsiblings at that moment. I pushed the button to our floor before pushing her up against the side of the lift. Letting her feel how hard she made me feel. We reached our floor and we got to our room as quickly as possible. I was nearly bursting out of my trousers. I needed her badly. I got the card key into the light switch before moving us into the room.
"There's no going back." I said as I pulled off my jacket.
"I need this." She laughed, taking off her own jacket. Kimmy never stopped. She pulled off her dress and her thong. Naked in front of me. My stepsister was naked in front of me. "Your turn." She brought a hand between her legs and rubbed herself.
I licked my lips watching her. I stripped off quickly. My own desire needed her. My boxers were the last of my clothes I stripped off. My cock bounced out of its confines as I pulled them down. "I want that little mouth of yours on me. I imagined it in the cinema."
She fell to her knees and shuffled up to me. "Me too." Wrapping her mouth around me. She had done this before. Her tongue swirled around me and she made sure to suckle the tip of my cock.
"Oh Kimmy!" I moaned as she took me deeper in her mouth. "Fuck!" Crying out as she took my whole cock. I grabbed her head and held her there. Her mouth felt so good. I pulled my cock back and out of her mouth. "Good." I held my cock and stroked myself slowly. "On the bed, legs wide."
She did as I told her. I took a good look at her. She was perfect. Small breasts, shaved cunt and tight body. "Fuck me, James!"
I climbed onto the bed and on top of her. "I intend to." I lifted one of her legs around me and I positioned the head of my cock at her dripping entrance. I watched her face as I thrust hard into her.
"FUCK!" She cried out. Her back arching as I filled her. "Big!" Was all she could manage.
"So fucking tight." I groaned and moved in and out of her slowly. Savouring the feel of her around me. Her arms wrapped around my neck and pulled me down on her more. I kissed her hard on the lips as I moved quicker in her. She felt incredible around me.
She pulled her mouth off mine and let out a little cry as I moved quicker. "James!"
"Ride me." I held her close and turned us over, so I was on my back.
Kimmy sat up straight, resting her hands on my chest and began to move on my cock. Rolling her hips back and forth on me. Our eyes met. We did not look away as she moved on me. Her movements quickly changed from rolling to bouncing. "Fuck!" She moaned as she did, breaking eye contact with me to throw her head back.
"Oh Kimmy!" I was getting closer, but I wanted to savour her on me. I reached over to her and pressed my finger on her clit and began to rub it vigorously. "Cum on me!"
"OHH YES!" She cried out as I rubbed her hard. Her walls tightening around me. "James!!" Stopping her movements as she came on me. Holding herself down on me. She collapsed forward and I wrapped my arms around her. Waiting for her to be ready again.
I held onto her and flipped us over. As much as I loved seeing a girl bouncing on me, I prefer to finish while on top. "Are you on the pill?" I asked her as I slowly moved within her.
"Yes." She moaned as I pushed fully into her.
"Can I cum in you? It's what I prefer." Trying to persuade her. I loved cumming on a girl but cumming inside one was a whole different feeling.
"Please cum in me!" She lifted a leg around me. "Fuck me hard."
I didn't need asking twice. "As you wish." I held myself up and moved my hips back and forth hard. God, I needed this! "Touch yourself," I grunted out as I quickened my pace. I was going to cum soon, but I needed to feel her tighten around me. I needed her to cum for me before I did.
Kimmy moved her left hand down in between us and located her clit but her other hand reached behind me and grabbed my ass. "Faster," gasped my stepsister as she rubbed her clit. I obeyed her. The bed creaked under us as I picked up the pace. I could feel it. I could feel the build-up in me. "Cum on me, little sister!" I couldn't help saying it.
And she did. "Fuck!"
I held still for a moment as I felt her tighten around me. I was done. Holding myself fully inside her, I came. I gave a couple of small thrusts into her as I emptied myself into her. It was wrong but fuck it felt good.
