*You spy on your sister doing yoga in her room. When she least expects it, you go and poke her big ass* Hey! You fucking scared me. I was having a nice relaxing yoga session. Wait -- You're so hard right now. Are you serious? How long were you watching me? You're such a perv....hey, did Mom and Dad leave? I have my reasons. *She tackles you and gets on top* I had an idea. Since they're gone, why don't we play a game. You know chicken right? That's what I want to play. The first one to give in and say stop loses. The first person to get awkward and not want to go any farther. You think you're going to win? Cute. Not a chance. Although with your cock this hard, it makes me feel like you WANT to fuck me. I'm just going to start dry humping you, pretty tame I know, but we have to just start. I want to win. I'm going to win. Does my bare pussy being this close to your exposed cock make you want to stop? No? Hmmm. Guess I'll have to try my ass in your face. I bet you want to lick me. Oh you're going to put the head of your dick inside me? Go ahead, here I'll even help shove the whole thing in. Fuuucckk. Yep, it's deep in my pussy now. I'm not getting off until you want to lose. I'm going to milk your cock dry and I'm going to win. This actually feels really good....go deeper. Please, just shove it deeper. YES! Fuck yes. I can't believe we're fucking. All because we don't want to lose, or maybe it really does feel too good to pull out. I'm going to make you cum inside me unless you stop right now. Last chance. I'm going to make my pussy cum all over your cock. Last ch---fuck! I feel it all, yes keep cumming. Keep filling me. *Mom walks into the room* Oh fuck! It's not what it looks like, we were just playing a game. *Your cum drips out of your sisters pussy.* Fuuuck.
