No sooner had I hung up the phone than I grabbed my binoculars, positioned on my bedside table for just such an emergency, and ran down the path to Va...essa's beach. I didn't bother to put on any clothes. After all Vanessa wouldn't be seeing me, or so I thought. Fifteen minutes later I had taken up my position behind a convient tree, binoculars in one hand, cock in the other. Vanessa must have settled for a short swim, because she was just exiting the water as I arrived. I let go of my dick just. “Are you coming over Saturday for more lessons?”“Yeah,” I muttered, unsure whether to let Katie see very much enthusiasm from me about spending the coming weekend fucking her mother. I know the lessons were Katie’s idea, but still... “Mom and I have talked,” Katie said as she slipped under my arm. “She really doesn’t think she can teach you much more, but she wants you to keep visiting. She hasn’t even dated since she and Daddy divorced, and she’s really been enjoying the sex.”“But I’m going to. Steven had been great, and she couldn’t ask for more from a husband. She wondered sometimes if she was wearing him out. They used to have sex two or three times a month, and now it was several times a week for three weeks of the month. And she wanted it during the fourth. She had to give the doctor credit. He had been imaginative. It had become difficult for her to imagine new sexy ways for her husband to find her when she came home. There had been a few good ones, of course, but after today,. It had really stunned her when Skip had said that he wanted to fuck her. She couldn't imagine withstanding the assault of that enormous fuck-weapon of his up her cunt. It would kill her for sure."I'll start eating when you take off your clothes," Skip said. "Come on, Sis, what's your hang-up?" Oh, all right!" Jenny dropped her fork, stood up, and started unbuttoning her blouse."That's my girl," Skip said. "Nice. No bra. Now peel down those shorts. No panties, huh? That's sexy."Jenny dropped her.
