I supposed she had been getting poked by my morning erection, and resolved to do something about it. I opened my eyes, and could see that she was conc...ntrating on masturbating me. Her face was very close to the tip of my penis, and she occasionally bent her head and licked the head. When she realized that I was awake, and watching her, she looked up at me and smiled."If it's okay with you, I want to do it this way. I need the practice." Whatever you'd like, I'm enjoying it."

She had never let me do her doggy style but here was a guy that she hardly knew fucking her like a wild a****l. Her skirt was up around her waist and her panties were still around one ankle. Her small B cup tits free from her bra which had been pulled up. I watched them for a couple of minutes shaking with anger but also something else. For some reason I was getting very excited.

The idiot laughed at me and told me to get out of the way or I'd get what she got. Oh the look on his face when I blocked the strike. They then went up to bed together, I sat and watched one of our films again before going to bed alone.Chris didn’t have a repeat of the morning before as Ben had left her asleep when he left; I took her a mug of tea to wake him up for work, where she thanked me for letting her spend the night with Ben, I left for work leaving Chris in bed as she had a late start that day.Chris got home to find Ben already there, he introduced Tony to her (I’ll let Chris describe him).Tony is about 5ft 8ins, mid.
