They tossed a Frisbee I had brought in my back pack, played chase, wrestled and in between chatted with Annie and I. They knew quite well that they we...e being watched, and after a few initial awkward moments they settled in and put on quite a show. The shirts clearly displayed their breasts, with Jessica essentially naked from the waist up in her sheer top. The shorts provided a perfect and bold outline of their tight young asses and pussies. Wearing shorts even Jessica had outgrown, Amy's. They both watch me clean her distended cunt. “That’s it. Lick me good. Clean me while I take care of Charles. Does my pussy taste good with his cum?" She points to the stream on her thigh. “Don’t forget that.” I lean up to lick up more of his cum, and go back to cleaning out her cunt. “I think you got most of it. Now it's your turn to fuck me.” As I slide into her cunt, I cannot believe how hot and wet she is. “Does my cunt feel better? Did Charles do a good job of fucking me?” “God..honey, I. ..”“Don’t worry. You will think about it and you will get over it. You’ll be fine. I have to go through it yet, myself. When it hits me, probably tonight when I go to bed, it’ll be like a ton of bricks, but ... I’ll get through it. It’ll be easier, I think, if you do take me up on my offer, since I’d have something to look forward to, and, well, I hate to be this way, but so would you. I can help you, if you’ll let me.”I squeezed her fingers lightly in my hand. “OK. Let’s just say it’s a done. She quickly covered self up, but not before I'd had a good look at her cunny and tits.Pretending to be indignant I said for Gods sake mom bolt the door when you come in here ! I waited until the w/e and oiled her bedroom door hinges cos I knew that she usually had an afternoon nap.I then left a note in the kitchen saying that I was out probably until the evening, and then hid quietly in the spare bedroom until I heard her go into her room and start undressing.I waited a bit and then walked in.
