My older sister Alex has invited me on a vacation with her to Vegas. It was going to be her and her husband but at the last minute work prevented him from going. Now it's just us against sin city! The first problem, after a long day of slots, poker and some drinking we come back to the hotel room and there's only one bed. The second problem Alex tells me is that the only way she can get to sleep is by masturbating before bed.Maybe I'll just step out of the room. But when my sister takes off her cloths to her tight underwear I hesitate. Its ok bro, it will only take a minute She tells me and hops onto the bed. I'm paralyzed with fear and awkwardness as she spreads her legs and rubs herself moaning and looking at me as I watch. Holy ! She's never done anything like this when we were growing up. She cums, screaming and shuttering.Why don't you masturbate? She asks. It will help you sleep. I tell her that it's ok but she insists. Come on, I'll even help you. She giggles. She pulls down my pants and begins stroking and sucking me. That's it, cum right in your big sisters mouth. She whispers. Her talking like that makes me cum and she swallows with a self satisfied look. I'm speechless as she says. Ok night bro and slides under the covers.

The next day is so awkward. I avoid her as much as I can until that night when she has two tickets to the topless burlesque show. You can't say no, I spent so much on these tickets She tells me. The entire night she bumps her knees against mine and once she slides her hand along my leg.We get back to the room and I quickly get into bed before she can do anything like the night before. Alex goes to shower and I think I'm safe. When she comes back out she's dressed in lingerie like the burlesque dancers. Wasn't that so hot? She asks, slowly dancing in front of the bed. I'll never be able to sleep tonight if I don't masturbate. She straddles on top of me and looks down at me under the covers as she rubs herself.Alex grinds against me, pulling out her breasts and cumming, moaning into my ear. Your turn She says and pulls down the sheet. I know you want to cum too, I can feel you. She says. It's ok bro, I'm your big sister, I'm just doing this to help you fall asleep Alex strokes and sucks me. Sliding her big breasts along my cock. Her feet wiggle in the air as I cum in her hot wet mouth. Night bro She says, a mouth full of cum before going to bed beside me.

Remember when we were little and I would hold you down and make you lick my feet? She laughs putting her feet in my face. How about you lick something else? She suggests, and slides her pussy against my face. Alex moans and thrusts against me making herself cum. Thanks bro She laughs.Now what am I going to do with this wet pussy? She wonders pulling down my pants. I try to escape but she has me completely controlled. Alex sucks my cock again until I'm good and hard, then fucks me. What the hell is my sister doing, this is so wrong but I can't do anything about it. She bounces up and down moaning and touching her large breasts until she cums again. No no no, you don't get to cum yet She says taking her panties, shoving them in my mouth and blindfolding me.

She's left me like this all day long. Tied to the bed the taste of her pussy still on my lips. I hear her enter the room and after a while she takes off the blindfold. She's dressed hotter than I could ever imagine. I'll let you go big brother, but you have to promise to fuck me and get me pregnant What the fuck did she just say? I think. Fuck your big sister and get her pregnant. You know you want to cum inside me She teases.I feel her get on top of me again and suck my cock. I'm raging hard when she slips me inside of her. Fuck me, and let me have your She begs me untieing one hand, then the other. I can't take it anymore. I give her everything she ever wanted. I fuck her around the bed making her squeal. After days of being teased and used I let all my frustration and sexual tension out into my sisters tight pussy. She begs me to cum inside of her and I let it out, making her cum as I cum. She lays there on the bed panting cum dripping out her when she says I love you bro.
