After a little while he invited me to come back to their place to hang out some more. After a few drinks and some ground rules he started making out w...ith Samantha and taking off her clothes. I was very excited to watch them and stripped my clothes off and started touching myself sitting just right next to them. This was not my first threesome so I knew to just take it easy and slow and let them do the leading so I would not upset them. Gob started fucking her pussy hard and turned her over and. . and the entire bookcase came forward. Surprised, she kept pulling. As the back of the book case came out beyond the front of the wall, there was suddenly resistance on the right hand side. Lessa found herself swinging the case open like a door. She stopped when the end of the bookcase came flush with the wall, stepping around to look at the revealed opening.There was now a large indentation in the wall, a bit over a third of a meter deep. The back and right sides were solid, but the left side. My hands caressed the roundness of her breasts, my finger and thumb pinching her nipples to hardness. She squealed in delight then I lowered my mouth to engulf each peak in turn. Her soft sighs encouraged my exploration as I dragged my tongue across one nipple then the other. I don’t think my warm lips missed a single inch of her as I explored, searching for her secret places of erogenous pleasure. My soft fingertips trailed along the creaminess of her inner thigh. I could feel her stomach. In the middle of the night I went to toilet and when I came back I saw that one guy is standing near my wife and trying to kiss her… his hand was on her ass... I came to them and told him to get away ,he just smiled me and left. We returned to our friends and continued drinking. Some time passed and 3 of my friends left home. We decided to stay on afterparty at the same bar. But soon I saw the same guy that was trying to kiss my wife… he was not alone… he was with the group of men, there.
