I kept cumming and cumming, and the pills she got for me made it feel even better and made me cum even more than usual. A moment after I started to cu... I stopped, and pushed in one last time. I got low and kissed my sister. “That felt good,” I said. She panted heavily and was rubbing herself as hard as she could. Then she snapped into realization. “I haven’t taken birth control pills in months, Rick!” she shouted.“Oh well,” I said. I began to slide in and out of her slowly, giving her more. "Fuck she's wet!" RuthAnn reddened. She was humiliated, and excited. Then she felt a wet finger wet from her juices. Felt it press against her asshole. She tightened. It circled it gradually increasing the pressure and then it went to the opening and pressed. Not hard but RuthAnn stopped breathing. After what seemed like an eternity, the finger returned to her lips and started their caress. They delved between her lips which were now soaked. They found her clit and electricity shot through her. Darren followed me on all fours, prowling like a large cat ready to devour its prey. He straddled my torso, his cock resting between my tits. He grabbed both my hands and pinned them to the bed above my head, making me feel vulnerable but desperate to be fucked. Grabbing the bottle of lube, he held it high above me, allowing thin streams to rain down on my nipples. The sensation was overwhelming. Darren rubbed my huge breasts, spreading the oil around, my nipples catching on his fingers. Easing. She was indulging her newly discovered sexual appetite and for the most part felt safe about the way she was doing it. She felt she could talk to Ben about anything because he could talk about anything to her. She could consider and explore erotic desires she never would have thought about doing in real life. Like sucking a cock, something she had never done before but Ben seemed to enjoy the idea so much she enjoyed playing along and describing how she would suck Ben's. After a while she began.
