(Added Covers and pixiv)

"A genetics laboratory found a comatose young woman grappled by a strange, mutant creature with a human face. They brought them into the lab and found that she was rapidly being impregnated by the creature. The changes were sudden and painless; in fact, the woman orgasmed continuously, even through the eventual childbirth. The scientists (a lovely, but cold woman of unsurpassed beauty, and an ugly yet brilliant geneticist) found the results fascinating. However, after a few moments they found that the woman's half-spawn was promptly latching onto his mother, with intend of arousing her again. Unfortunately, their genetics were incompatible. A fresh human vessel would be needed. The scientist had a plan: his lovely assistant would do! As the lab guards seperated the girl from her spawn, the scientist forced his assistant into the room to be the next specimen. At first she protested and fought to get away, but as soon as the creature (which was growing rapidly) touched her skin with its slimy tongue, she was immediately and fully aroused beyond reason. The young scientist thrust her nubile young body at the creature intent on mating. The scans showed that she was at peak fertility and that her eggs were produced. It didn't take long for the copulation to reach a climax and the result was the end point genetic mixture that we now know as Grubman! But her job isn't finished. The laboratory needs more Grubmen and more specimens..."
