As he stroked, I removed my panties and started to finger myself as well. He was watching me with anticipation, then said he was about to cum. I was a...azed to see his first rope of cum shoot back over his head onto the pillow, followed by three shorter ones on his chest and a few more smaller ones on his pubic hair. I couldn’t believe that I had just witnessed my son jacking off. I kept going on myself for about 10 minutes until I also orgasmed. Harrison said “that was so kewl mum, I didn’t. There was a icon that read "my dog and me" I opened it and briefly read threw it. It was gross but for some reason I was getting hard thinking about Crystal reading it. I thought to myself "what a freak" I was kinda in a hurry so I put my laptop up and finished getting ready and headed off to work.

Brain damage according to my kids!”Marcia laughed, “Your daughter is a real smarty-pants!”“Yes she is! Are you ready to try again, this time at three-quarter speed?”“I think I’m going to be black and blue before we’re done!”“You want to win, right?”“Yes, Sensei!”“Then let’s begin!”We spent the rest of the time with me correcting. Liza is stroking us both, and just before I'm about to tell her, she must stop or else I'm going to cum; she says, "Why don't both of you lay on the bed and sixty-nine while I watch and play with myself."I'm not all that experienced, but I know you never argue with a lady when she's got your cock in her hand, so Matt and I climbed on the king-size bed, laying on our sides in a sixty-nine position. I can tell it's going to be awkward with me being much taller than Matt. His being in the right.
