I can take a hint and I started working on her pussy with one hand and, after a while, my mouth, while my other hand played with her big breasts.She w...s just about on the point of cuming when I heard Jon say, "Well, what have we got here?" He had arrived home and stripped-off without us hearing, and was now stood just behind me. I stood up and Hannah said, "Oh my god!" and started struggling. Jon walked all round Hannah looking closely at her and then said, "I don't have to ask what you two. We had had a couple of lesbian get togethers but we hadn’t involved any men at that point.
