I don’t know why but we both continued to watch our daughter. Neither of us go upset when she lazily slipped her right hand down her flat stomach an... dipped her hand inside her shorts. Herleft hand held the book up so that she could read and it was obvious from the way she spread her legs and the slight movement of her hips that she was fingering herself. My wife and I watched mesmerized. What happened next, happened quickly. I heard the truck door slam in the driveway. I figured it must be the. Half way through the next slow song I came back in with the drinks to find Debs and Andy french kissing and grinding to the beat of the song. My cock bulged in my trousers seeing them.Andy broke off quickly when he saw me and tried to apologise. I told him to relax and continue. Besides what were friends for. I went and sat down, Andy was hesitant then realised I was serious and went back to kissing and dancing with Debs. Soon his hands were all over her. Grabbing her ass and pulling her tight. I was glad she was having fun, but I didn't want to ruin the mood. I gripped both sides of her head and began to fuck her face/throat with slow and deep strokes."You love this don't you, you dirty big titty whore?", I said as I fucked her face."Mhm ah hoo." She hummed around my cock. I grabbed the front of her top, and unbuttoned it down exposing her bra. I reached into each up and pulled out her heavy tits. I felt nipples piercing as I pulled her fat tits out. Her nipples puffed out, they. And I teased her like that.She started begging me to fuck her. I separated her legs more wider and kept my dick on her pussy and there is a shocking response from her body. She hugged me very aggressively and kissed my lips simultaneously she guided my penis towards her pussy.I forced my first thrust and it went inside and she started screaming ammmaa, ahhhh, ishhh, ammma , mmmm it made me go wild and with full force I pushed my penis again and it went fully inside.. And I started fucking her.
