I watched her body, watched her face, listened to her breath, and slid my fingers all the way in. She gasped for air, and her hips tilted to take my f...ingers completely. Found it! I moved quickly in between her legs, not giving her time to protest. My tongue met her clit, which was covered in her warm juices. She dripped all over my fingers, and I watched rivers of her nectar find their way down her ass cheeks and drip onto the couch. I engulfed her clit in my mouth, sucking, licking, dragging. We both were nude so I opened the the shower .I licked her pussy and she started moaning loudly I was licking her pussy so I cant stop her from moaning and after sometime I was able to stop her from moaning suddenly someone came on the door and said ashu what’s that noise .I get afraid .Her sister was at the door. After sometime she replied nothing just singing. Then I get normal and then she said stop licking start fucking me . She holded my cock and guided it into her pussy . I penetrate my. She slid her pussy along my length, her ass rubbing against my stomach. With my free hand I grabbed her hip, steadying her and pressing her harder against me.Slowing the pace, she rotated her hips forward a bit more. With careful control, she let my head press between her pussy lips. Each firm rock of her pelvis brought my dick farther between her lips, until I felt the pressure of her pelvic bone vanish into softness. The head of dick was now right at the entrance of my sister's vagina,. Protruding from the center of it, about four feet up from the ground, was a large barrel with straps screwed into it. There were two other wheels, higher up; one with leather straps dangling down and the other was rimmed with short, but very sharp metal spikes.Tanya frowned, looking at it. "Looks interesting ... How's it work?"Frank led her over and backed her up against the barrel. He pulled her polo shirt off and tossed it aside, then pulled down her shorts. Tanya helped him by kicking them.
