Only a very stupid, very suicidal or very sex-crazed girl will entangle herself in the web of the Giant Spider. Evolution scientist are still puzzled why neither the Giant Spider nor the Stupid Girl is extinct yet.
The Giant Spider inserts its egg-tube into the victim and impregnates it. How it gets the eggs through the cervix (which is normally firmly closed in any normal woman) is one of the general mysteries of the tentacleporn genre. Simply don't think about it.
Bringing their sex-partner to orgasm by vibrating strings belongs to the normal mating repertoire of spiders. It comes in also handy while dealing with human women, as a) it keeps the victim subdued and b) spiders can only feed on liquids and female love juices are very tasty and nutritious. (Any spider recommends.)
When the eggs are ripe to hatch, the victim is cocooned. Most victims are lucky and the perpertual orgasm already sent them into sweet oblivion, as it gets very nasty now.
The Association for the Prevention of Cruelty to Fetish Comic Victims assures us that the poison of the Giant Spider turns the girl into liquid food in no time. (Schematic "x-ray" inset added for more horror.)
And such ends the girl and also our little biology lesson.

Unless you wanked away too much of your brain cells this should be an easy task of glueing together.
