A dirty conversation led to some heavy flirting, and by the time the jokes, the sexual comments, and the joking remarks about teenage girls were done,...my step-daughter's friend, Allison and I wound up skinny dipping in my pool. My step-daughter Sierra had gone to bed with her friend Jamie. Allison had come downstairs, we'd been flirting, joking, and making sexual comments. I had no idea what to expect, but I know for damn sure I didn't expect to wind up seeing this cute petite little teenage. She just smiled, and said, "Like... what, big brother?" she took another of her sexy bites. Her eyes watched me, as I watched her eat. She made sure to give her red lips an extra lick."You're a tease," I told her, "Let's go dance before you kill me," I took her hand, leading her to the bar, and dance floor. I looked into her eyes, "You're so beautiful." I pulled her against me, letting her feel how hard she had made me.She moaned when my hard, 10 inches pushed between her stocking covered legs,. .. yes...” she groans, closing her eyes and lifting her pelvis against his thrusting fingers. “Please fuck me. Make me cum.”“I’m going to make you cum over and over again, sweetheart.” He promises her with a grin, flicking his tongue at her nipple once more before taking it between his lips and sucking hard it, moving his digits faster inside her.“Yes ... more...” she begs, holding his head tight against her, lifting her hips against his thrusting hand.“You want more? Like this?” He slides a. I felt more tears in my eyes as he slammed what felt like 8 inches into my now non virgin cunt. It hurt so bad I couldn’t even scream in pain. He slowly pumped in and out of me as his heavy breathing fills my ears. “You’re such a good girl for taking Daddy’s cock like this. Mmmm I hope my baby girl get’s pregnant.” He laughed sucking my bitting my nipples. Finally getting some strength back I tried pushing him away again but all he did was pin my arms above my head again and lift my lower body.
