Jake was playing with Julie's tits while she rubbed Jake's monster through his jeans.After a few minutes, Jake told Julie to put in a movie. Nina's ey...es were riveted to Julie's ass as she sashayed to the tv. When Julie bent over to put in a movie, her tee rode up, exposing her big, puffy cunt lips and puckered asshole. As out of the mood as Nina had been, she was now becoming very aroused. She'd never been turned on by another woman before, but her juicy lips couldn't be denied. At that moment. I glanceddown at her, then tried to focus on a cigarette ad on the wall as Iwas bounced into her again and again. She shifted a little, and herbutt rubbed against my crotch.It was too much for me. I felt a chill of horror as I felt my body beginto respond. I swelled in my jeans, and the sensations increased asI moved against her, causing me to swell even more. Within seconds,I was hard as a rock.Sweat broke out on my face as I realised she was going to notice.She would feel my hardness against. We had devised a harness from several seatbelts and using a length of attached heavy wire the girls would drag the burden to the beach. I overhead "yassur boss" comments addressed in my direction as a result of this labor. I had also noticed Jennifer took a delight in using a switch on Brittany's behind if she felt the other girl was lagging.The girls had deepened their own special relationship apart from me. Both girls considered themselves "straight" and the developing sexual need was. As my nerves were shaky in anticipation and my cock getting warm and dripping precum, I waited for my moment. Before I knew it, the shower curtain swung open, and there, behold, was the view I had waited 3 long years to see–my s****r-in-law completely naked. The first thing I saw here her amazing breasts, the most perfect site I had ever seen! There they were, 44DD naturals on a relatively small frame. They suspended themselves in the air magically, no extreme sagging, etc. I wanted to bust.
