She bent down like dog and guided my dick to her pussy as she was in uncontrollable mood. Slowly I inserted my cock inside her pussy.My cock reached h...r hymen.She tried to stop me as it was giving little pain to her. But I ignored her. I took out my cock waited to catch my breath and again pushed it in with full force. She screamed, “Oh God, help me.” My hands were all over her lush body, gripping her breasts. When I started to move in & out of my cock, the poor sister would let out a terrible. Afew days had gone by, and neither of us talked about that morning. I however, couldn't stop thinking about it. The next time Tim joked about sucking my dick, I was gonna call his bluff. The very next morning we pulled up to the beach, it was still a little dark and there wasn't anyone else in sight.
