"No, I'm fine, thanks." I started to turn red from embarassment (who wouldn't?). She slammed me down onto the sofa, and without warning, started rubbi...g my jeans. "I saw you looking at me, Robert. You aren't very subtle." She stated. "Sorry, but who wouldn't stare at you dressed like that!?" "Shut up and unbuckle your belt, and pull down your drawers." My sister easily overpowered me, as I was shocked by what was happening. I did as she said, but stopped at my boxers. "Too scared?" She said,. ”Then I opened her tied hands. As soon as she opened her hand, she laid me on the bed and sat on top of me! She grabbed me and started kissing me. I was pressing her breasts hard.Then I started taking off her clothes. She was wearing a black bra inside in which she looked hot as a model. I unhooked my sister’s bra. As soon as she opened the bra, she handed her body to me. I started licking her boobs. I put a love bite on her nipples while she scratched my back, her big nails digging on my skin. Her breaths grew sharper as my pace quickened slightly, I could feel the very edges of an orgasm coming on. I continued, still at a fairly slow pace, slowly bringing both of us up.Another hour passed as I alternated between fucking her gently, and kissing her passionately. All the while our breaths grew more ragged as we got closer. Resisting the urge to speed up I kept my pace, our tongues danced about each other in her mouth… mine…in the cool night air as I pulled away slightly, then went. As Daryl waited for Cindy on the blanket he’d brought, he thought about what a weird day the four friends had spent together. He never expected Cindy to be so open about nudity and all of the displayed sexual action. God, she was so beautiful. Kim was beautiful too and she was soooo comfortable with her body and sex. He was delighted when she spread her legs wide to show Brett her pussy. This was of course only the second pussy he’d seen and he found the similarities kind of neat. He also kind.
