Then she grabbed my floating cock and squeezed it roughly. "Oooh!" She said squinting her eyes and puckering her lips.I quickly seized the moment and ...ulled her into slightly deeper water. The surf was gentle and the swells slowly lifted us and then dropped down just below her breasts. Lisa placed her arms around my neck, spread her legs and wrapped them around my hips. She felt so light in my arms because of her buoyancy. I was in a position to concentrate on sex rather than trying to figure. Mom's lack of surprise when she'd seen Emily and me that time and said how good we looked and I'd told her Emily's parents had had the same reaction was another hint."So, what's the deal with my parents, do you think?"Emily and I were stretched out on the grass, still nude, after showering and cleaning up."They aren't mad, that's for sure," I added.Emily snickered."Haven't you figured it out yet?"I turned on my side to look at her."What?" What your parents are doing, Daniel."I must have looked. "Do you mind if I do?" she then asked.I was still speechless up until that moment, but then I finally found my own voice, though it honestly quivered a little when I spoke."You're uh ... you're husband enjoys doing this too?" I somehow managed, realizing as I said that, I had just confessed to doing it more than once, though even that thought would have appeared ridicules under the circumstances, though I had briefly entertained saying that by way of some excuse for what she'd just caught me. Around the house as usual, she was barefoot."What is it you wanted to talk to me about?" She asked after a few minutes of casual talk and glancing at the TV."I wanted to talk to you about uncle Cliff." He began, searching for the best words."What about uncle Cliff? Is there something wrong with him?" She asked, being totally ignorant of what was coming."I know what you two have been doing when dad is away!"The statement struck Mavis like a bolt of lightning, but except for her body tightening.
