I suspected he was a virgin and told her so. Without any shyness, she said that she would teach him about women and quoted a price to do so. I laughed...and said, “So you would fuck a father and his son both?” She gave a big smile and said it would be a treat for her as well as for us. I decided my son was old enough to learn this and this was a terrific opportunity.Although he acted as if nothing had changed, she filled me in when I was next pumping in her welcoming pussy about how his lessons. "You will be dressed and not in pyjamas?" he asked, but not in a hostile way. She giggled, there were seconds of silence and then she said "I think I can improve on that".So far he hadn't considered her as a source for sexual adventure, however, because of the afternoon tea that was to change. She opened the door wearing an attractive house coat; it was tied by a single belt. He had no idea that she wore nothing under it; she served a very pleasant afternoon tea and when the cups had been put. So anyway, that Friday Tara and Keisha dropped us at work on the way over to their places to pick up clothes and whatever; I really didn't see why they NEEDED clothes, but apparently it was to keep Beth's sisters from freaking out on arrival. Yeah, well, okay, I guess. Beth and I wore our usual stuff -- jeans and a blouse -- but we wore the spiked dog collars, too. That got us questions all day and a little hassle from one of the managers, who tended to be an asshole. But we weren't DOING. What would I do for her to touch me again, get me the release I need? This is excruciating, so mean for her to stop here. I breathe deeply, as frustration and desire run through me. I get up from her examination table, picking up my boxer, and slowly putting it on. I see her looking at me, like a lion spotting its next meal. As I’m pulling up my underwear, she seems to be on the edge of jumping at me. I want to tell her that she can, that I’ll fuck her until she can’t stand it.My boxers finally.
