Monster Erotica - Intrusion

Married scientists Monty and Nerissa think they’re about to make history with a new invention that offers glimpses of alternate dimensions. But during the device’s trial run, a hulking monster appears in the lab, and when it lays eyes on Nerissa, its only aim is to have its way with her. After his attempt to stop the alien intruder leaves him pinned beneath a piece of heavy equipment, Monty can only watch, helpless and horrified yet strangely aroused, as the hugely hung brute roughly claims his wife…and in the process gives her pleasure light-years beyond anything she has ever felt with her nerdy husband.
