Our forbidden secrets (18+)

Me and my step brother are in the car on a long car ride on our way to vacation when we get their we explore the cabin finding out theirs only two beds one for our parents and one for me and him. We put our sheets on the bed he asked me to do the edges against the wall as well bend over and stretch tords the edge tuckin it in as as he stairs at my tiny shorts riding up showing my ass. I turn and smile at him as I get up looking him deep in his eyes asking him if he liked what he saw as he blushed looking away. As the day goes on we go down to the beach and I pull off my clothes leaving a tiny bakini and I sit in the sun for a couples hours. We get home wen it's dark our parents decide to stay out side and talk wall we walk in as I look at him and smile telling him l'm gonna jump in the shower and go to our bed leaning over as I grab clothes for a shower. He smiles and sits down beside me smiling asking if I want him to join as I smile pulling off my bathing suit top and throwing it at him going into the bathroom starting the shower as I get in and wash my body off. Wen I get out he's sitting in the room in the bed in just his boxers I smile and sit down xt to him and grab the blankets. I pull the blanket up sliding off my shorts and laying my head down as he gets comfortable laying opposite of me. We get comfy in bed and I wait a couple minutes as to where our parents fall asleep I get up crawling to his side of the bed laying down nxt to him pushing my ass against his d**k as I feel his hand grab my hip as he slams me back into his rock hard d**k. I roll over tords him and smile pulling him close to me whispering I want u inside me. I smiles getting up pulling off his boxers he leans over top of me I smile opening my legs as he leans down kissing me I rap my legs around him and slide him into me. I arch my back as I let out a soft moan. He covers my mouth so no one can hear as he plunges deeper into me as I rap my arms around him grabbing tightly onto his back digging my nails into his back bc of pleasure. He thrust into me harshly as he pulls out getting off me and violently rolling me over grabbing my hips pulling my ass up slamming his shaft into me as I clench the bed sheets moaning loudly. He leans down grabbing a chunk of my hair pulling back and whispers in my ear telling me to shut up or he’s gonna punish me. I nod as he pushes my head down into the bed leaving one hand on my head and putting the other on my back as he starts slamming into me each stroke going deeper and deeper. I try my best to hold back my moans as he does so. He looks at me grabbing my hair again yanking my head back still pushing on my back. He whisper yells at me I told u to stfu as he spits on my face pushing it back into the bed. He starts stroking again and goes in one last time balls deep as I feel his warm semen fill my body. He hold him self there as he looks at me. He pulls away as his c*m drips out of my p***y down my leg. He smiles and leans down facing me whispering that’s a good little slut.
