Her thighs tightening across my legs. I knew she was about to cum again. Fuck the though of her surging on me and orgasming almost made me cum right t...ere. “Fuck!” She screamed out at the top of her lungs! Her pussy tightened around me like a vise. My hands found her hips again, and I viciously ground her hips against mine. Her cries bounced across my living room, her nails raking into my chest. I was barely holding onto the edge. Every ounce of my self discipline holding on by its fingernails. Both Marie and I didn't have any k**s so at least Tina would have some peace and quiet around the house. We have two bedrooms upstairs and one downstairs and it was the downstairs bedroom that Tina moved into as it has its own bathroom and shower, which also gave us our privacy too.For the two years that she has now lived with us, Marie has only seen her go out on a date about half a dozen time and none of them has lasted longer than a couple of months. So Marie set her up with a couple of guys. Now she usually taught art, but one day one of the other teachers organised a field trip to a local forest, and she volunteered to help out.As it happened I was also on that field trip, as it was part of our geography course, and when Ms Johnson turned up in the car park to meet us at the minibus, we couldn't believe our eyes because she was dressed in a tight camouflaged t-shirt, short green camo shorts, and a pair of brown leather boots.After staring hard for a good minute at her stunning. . YOU BITCH..." she yelled as she kept slapping my face, and I kept crying. Finally after about a minute or so she stopped, and just sat there on top of me, breathing hard. "How could you do that to me, Teju? How could you fuck him even after you saw us doing it?" she said and started crying too."I am sorry, Anagha, I really really sorry" I said, sobbing.Anagha bent down, with her face very close to mine and gently wiped my tears."I am sorry too, Teju. I should not have... I mean I just wanted.
