Now she inserted her hands down and grabbed my dick and stroked till it was hard. She immediately went down and started sucking my dick to make me fee... like heaven. I was enjoying myself closing my eyes but when I opened them I saw that 2 girls were watching us from the apartment above ours. It was the Russian girls I told you about in my first part.I thought they mistakenly found us so would go in soon but no, they kept watching us without turning but giggling. When shruthi came up I got up. Lets see if i can fit that big cock of yours inside my pussy.I think i am going to be stretched like never before'.At this she lowered herself down and eased my cock into her pussy.'Oh god.That is a bloody tight fit'.She let out a scream as she took it all the way in.'Oh fuck.Oh fuck.Oh shit'.Once she had taken it all in she began to slowly ride up and down on me.I had to get her to take off the conical bra or i would have been bruised all over my face.Once she had done this i was able to see. Slowly fucking her with his fingers and changing to a soft but faster pace of sucking her clit, she started grinding her hips against his head while twisting the nipples of her breasts hard. She started moaning heavily when he penetrated her g-spot every time his fingers pushed deep inside her. "I'm getting close! Start rubbing the head of your cock against the tampon", she moaned. "If you can come by rubbing only your clitdick until I come, you are allowed to have an orgasm". His other hand. I told myself it was stupid, but I was gaining a slight hard-on that was making me guilty. I ran my hands up and down her back to calm her down, stroking her beautiful hair. I had always thought her hair has beautiful, but the recent summer highlights of blonde in her brunette curls were natural and gorgeous, tied back into a medium length ponytail. Again, I felt guilty, but decided I shouldn't. My sister was beautiful, and I knew it. I had always known it. Finally, she had calmed down enough.
