Noemy says, “I guess it’s just the idea of love I miss. And, well, it was a good kiss.” Her smile turns rueful. “At least I got some practice.” A wonderful idea occurs to Abel. “Do you need more practice?” “Huh?” “We could practice, if you wanted.He smiles as he starts to explain.Remember what I told you on Genesis? I’m programmed with a wide array of techniques for providing physical pleasure, via every activity from kissing to the more arcane positions for sexual intercourse. Although I’ve never performed any of them before, I’m confident I could do so very skillfully.” She stares at him, eyes wide. Since she is swift to voice objections if she has them, Abel takes her silence as an encouraging sign. So he sits up on the bed to explain the further compelling reasons now coming to mind. “Humans need a certain amount of physical release and comfort in order to be psychologicallly healthy. You’ve been away from your family and friends for some time, and have endured considerable trauma, suggesting you are in even greater need than usual. I have all the information and technique necessary to be an excellent partner, my body is designed to be appealing, and of course I can neither carry disease nor impregnate you. We have total privacy and many hours of spare time. Conditions for intercourse would seem to be ideal.
