Serafina gets it

Horvan resigned to the idea that Serafina would be lost to him forever once they set foot on Wox. He loved her dearly and would do anything for her, but alas, what was to be was going to be. Just before they left on the long journey that would last about two days in Earth’s time (Yes, the spaceships were that fast,) he spent a whole night making love to her. Of course she liked it when he partook of her feminine charms, but Horvan knew she thought of Mbobo and perhaps other Woxian males doing it to her, while he was doing the utmost to pleasure his super-aroused wife. And he knew he was damn good at it too, but could never compete with a Woxian male. The Woxian men were phallic giants. Their members could reach almost three-feet in length and be thicker than a human forearm when fully erected. And they were insatiable, especially when ravishing attractive Earthly women. They would stay erected indefinitely, even after ejaculating practically gallons of their explosive semen, many, many times. All that Woxian sperm could not impregnate the human women though, unless certain specific conditions were met, but that never bothered anyone. Nobody wanted half-breed babies anyway.
