Then he felt the hand cupping his crotch, and Tawny was whispering "Licker good tiger, Evan good fuck. Keep shirt on, big boy. Two cocks." She couldn'... mean what he thought. But he was suddenly stiff as a board. She was working his pants down.Then she was kneeling in front of him, sucking his tool vigorously as the tiger licked her ass crack. He caught Gina's eye, seeing the passion she was feeling as the the other big striped beast bumped her around while it licked at her butt, a smile of. That little incident got Rob and I talking about sex, while we were lying in bed after lights out one night. Being 13 and boys we tried to impress each other with our great knowledge of things sexual, until he finally blurted out that he was a virgin. At first I couldn't believe that he'd said it. I mean I was a virgin too, but I would never admit it to a fellow teenager.Then when he said he hadn't even jacked off yet I was sure that I was in the Twilight Zone. It started with me telling him. After a while of slurping and sucking, Libb lifted her head and said "Are you going to fuck us both now?" Yeah, fuck me and my sister with that big tool she keeps talking about," chimed in Meredith.Hubby let his swollen dong come out and Meredith's face lit up. Wow, it's as thick as you said it was sister."Fuck my sister first" Libb said. "Alternate fucking her vagina and anal holes and then my mouth," she commanded. "I want to taste my sister's pussy juice on your cock."Lucky hubby then. “I understand that the rules for girls and boys are different, Ma’am,” I answered.“No, if you were a little girl, then you could run around without clothes at the beach, and no one would care. There isn’t anything on a little girl but a tiny slit and a flat chest just like a boy. No one cares but once you start to develop like us then everything changes, Eddie.” My Aunt explained.She told me that as boys mature they start to like girls and they WANT to show off. She explained that as girls.
