They both were naked and my cousin upside to my sister and giving movements. I become erected by seeing that. Suddenly my sister is asking him to swit...h off the light as anyone from outside might see them. He was trying to convince her but finally he switched off the light. I disappointed with that and came back to my bed. After some time, the light was again been switched on. I immediately went to the window and seeing inside. They finished the sex and wearing the clothes. He forgotten to wear. I kiss down her huge tits they had big nipples on them I liked that as I kissed lower to her bellybutton I could feel the heat and smell that sweet smell of pussy. I couldn't take it no longer I put a leg in each hand as I sprawled her out eagle my tongue found her honey hole . I still remember the taste it was so good I didn't want to stop . But she pulled my head up and said that's enough I need cock now. She rolled over on all 4s resting her head on the sofa arm . Reaching back spreading. The sawhorse was sturdy but inflexible.I kissed her hard on the lips and then quietly asked her if she was sure this was what she wanted. She thought about it this time, but the lust in her eyes when she nodded was an inferno. I wondered briefly at that time just who was controlling whom in this relationship. Then I saw her nipple peek out at me, and didn't give a second thought.I reached down with my hand and got a firm grip on her thong panties. I had always wanted to rip a pair of panties. God I was already acting like some horny teenager!‘Mike! Come up would you’?I climbed the stairs – ‘Where are you’?‘In my bedroom - at the top on the right. Come in there’s something I want to ask you’.I walked in.‘What do you think?’Oh my God!! I was absolutely speechless. Susan was lying there sprawled on the bed wearing nothing but a sexy red bra and a matching thong. I could see her hard nipples poking through the bra and could even make out her areolae beneath the thin see through.
