She wasn’t even sure this qualified as intercourse, although it was admittedly a gray area at the moment. The two models, Cras and Almona, were sitting in a tank of water up to their chests and masturbating each other frenetically. “As you can see,” Quinn said, “the male Turbesan’s penis is still extremely receptive to stimulation despite being an undersized and largely residual organ.” Quinn was a New Earthling and, together with his Allurian wife, Xindra, instructed this course. The two of them were an example of an interracial couple who’d made it work and found something wonderful together. Katra didn’t want to admit it, even to herself, but she was jealous of them. “So the male never penetrates the female?” Spri, one of the other students, sounded bemused. Xindra, who wore her dark purple hair pinned up this evening, fielded the question. “That’s right. Fertilization for Turbesan couples is completely external, although both sexes can still enjoy orgasm even if the female isn’t ready to ovulate.” The couple certainly seemed to be enjoying themselves right now.
