“Just keep stroking this beautiful, big girl-dick until you erupt all that futa-jizz.” She let out a purring moan. “But... but... I have to do t...is!”She fell to her knees before me. She seized my cock with both her hands now, pumping up and down me fast and hard. Her mouth opened wide. Her wet lips stretched over the crown of my cock. She sucked on me.“Holy shit!” I gasped as she nursed on my cock while both her hands stroked up and down my shaft. “Mrs. Greene!”She whimpered around me. Her. The young then gestate within the neuter's body until they give birth to live babies. It's all very fascinating!" Fascinating it may be," I said, "but I still don't see..." but then I did!"Of course! 'Any biped without a phallus will do'!" I said, "So a woman can be raped by a female indigene, having the eggs deposited inside her, then raped again by a male, to fertilize the eggs!"Gail caught on too, "So women wear strap-ons to simulate having a phallus and avoid being attacked by the females!. 'OK' I think, 'If he does it again I shall confront him', no condemnation or hysterics, just a firm look should do the trick, and I wait for his touch.There are strong overtures of sexual innuendo in the air as I wait and wait. Suddenly I am getting frustrated waiting for that touch and subconsciously move back a little and make contact, now I am happy, he is there, closer than I thought, so now he will surely touch.I now realized I was wanting him to take advantage of the situation, I was open. As I opened the car door she slid into the seat, her gown had a slit running along the side, I was treated to a flash of bare thigh and the top of her stockings. “WOW mom dead sexy” I laughed, she playfully slapped my wrist and called me a pervert who ogles old women. We drove to the party and were greeted as a couple, my friends were astounded by the transformation of my mom. Many of them danced with her and complements came from all angles, at last she was relaxing. A slow piece of music.
