Your little sister sits you down and tells you all about how she is going to college soon, and wants to be experienced for all the hook-ups with the college guys but her bfs penis is too big for anal. Your is, perfect for my tiny little virgin asshole. Don't take it the wrong way! Its perfectly asshole sized! Will you take my anal virginity brother? YES!! You're the best big brother ever. Why don't we do it right now? I am kinda horny. I undress for you and then finger my tiny little asshole for you, eventually fitting in 2 fingers. Are you proud of me brother?? I am now ready for your cock in my ass brother. You insert it and my asshole engorges it slowly. Wow. It feels so good brother. You go gently with me and I use my vibrator too, having the best orgasms of my life with your cock stuffed in my ass in several different positions! Your gonna make me such a good little anal slut brother. Im addicted already. I ride your cock reverse cowgirl and encourage you to cum inside my asshole. You deserve it for fucking my ass so good. You fill it up and i push and squeeze the cum out of my asshole. Love you brother!
