Tina was just looking at me laughing as she played with this guys cock. I was in fucking heaven !!! I was rubbing her pussy and my cock at the same ti...e as she thrust her ass back and forth faster and harder. At that same moment I looked and saw the guys cock pumping in tinas hand as she rubbed her finger over the head of it. Tina jumped back as streams of cum began to shoot out. With a loud moan 4 or 5 huge shots of cum shot out! As I was trying not to cum myself, I started to rub tina hard. I said ‘just some more time.’ then I was touching her back and straps of her blouse. Her cleavage was pressed in my chest as she had no bra and i had no vest so I could feel her nipples. My cock was pushing her tummy. Then slowly i moved my hand on her lower back then on her butt. She said looking away,’ it’s enough we must leave’ .i said ‘just 2 minutes’ .I could see her enjoyment and lack of resistance. Her blouse left her shoulders visible so i gently kissed her shoulder and then her neck.. Sabrina got so aroused she came several times that night. Nothing was said until the following week when they made love again and Sabrina responded in much the same way having multiple orgasms.David had been reading stories on the internet about wives becoming hot wives and taking multiple lovers while their husbands became their cuckolds. David dropped a hint here and their during their love making sessions until Sabrina seemed serious about giving it a try. David was so excited that night. I smiled to myself and quietly opened my legs just wide enough for his fingers to find my pussy. I closed my eyes and bit my lip as Mitch’s fingers worked magic on my clit through the thin material of my thong. I felt so wet in a second and I nearly came in just the short cab ride to his flat…Feeling a bit fuzzy but very horny, I stumbled into Mitch’s place.Once there, Pete poured some drinks and we sat on a large couch.Mitch immediately started touching me, making flirtatious little jokes.
