My Straight Brother-In-Law

"I love visiting my brother-in-law. About once a month he'll invite me to go out with all his mates and I always end up getting pissed, missing my last train home and staying over. There's only one bed, but he doesn't mind sharing it...Of course in the morning I wake up really horny and ... well he's kinda cute, so I can't resist having a play... He lies there while I work on his big uncut cock, chewing on his delicious foreskin and taking the whole throbbing length down my throat.Then this one time I get a little bolder and climb right on top. I feel his thick length inside me and begin to ride him gently. Next thing I know, he's flipped me over and he's riding my arse, sliding in an out like a piston, then after a few minutes he rolls off and collapses onto his back! Maybe he's had second thoughts, maybe he's embarrassed about going too far...?I don't know, but do I know there's no way I'm stopping there, so I climb right back on top and ride his big cock til I'm shooting a hot stream of cum over his belly. When I've had my fun I hit the shower, leaving him to finish himself off. Well he doesn't need me there does he? He's straight, right?"
