Then I saw her hand placed between Carrie’s wide spread legs and Carrie’s head was bent back and resting on the head rest. They didn’t see me lo...king at them through the rear view mirror but after that first glimpse of them, I couldn’t keep my eyes off of their activities. I was driving a little erratically with my eyes glued to the mirror and I was having trouble keeping the Jeep in my lane. But I finally pulled it into the campgrounds and cleared my throat rather loudly as a signal for them. While the high ceiling would stop a normal person, I could scale the walls, cross the gap to the shaft, climb it, and get out onto the roof. I would have to take it carefully, I had never attempted such a difficult climb before, however I was sure it was possible. Approaching the nearest wall, I took off my shoes, and tied them carefully to my belt.Positioning my hand high on the wall, I gripped, made sure I had a good grip, then moved first one foot, then the other up onto the wall. I was now. "You got it!" She pulled away her hand and gasped."Not yet!" Mona cried out. "I want it all." Her tits heaved as she lifted her ass off the bench. "Fuck me, King!"King tossed his head and lunged forward. Spit dribbled from his rubbery lips as his cock fucked into the heated slit of Mona's pussy. He jerked again, his monstrous prick stretching Mona's pussy as the frothy cunt cream bathed his buried cockshaft."I got him!" Mona squealed as she rolled her hips and milked his stabbing prick. "He's. .. we actually fuck?" Sarah could hear a shaky exhilaration in her brother's words as he spoke... wow, she thought, he really, really wants to fuck me. Bad. She knew it was sort of sick and perverted, but Sarah felt incredibly flattered."So, you mean you want to stick your cock in my... ?" Teasingly, Sarah pulled open the front of her g-string, giving her brother a fleeting glance of the tiny, curly strip of blonde hair that lay right above her bare, smooth slit. The horny teenage girl's mind.
