Professor Marjorie’s Annotated Field Guide to Tentacle Attacks. Featured sub-class affixers.

An affixer is any type of tentacle beast the uses some form of external substance or symbiosis to trap and hold its victims immobile. In this case, the subject becomes entangled in the living mesh of a simple Type 1 Earth Demon. The web-like structure has the ability to to act autonomously, capturing and immobilizing potential victims, and alerting the demon who will then take control. Here, a healthy young female has been exposed and repositioned to the demon’s liking, and the mesh hardened into a semi-rigid cage of sorts. Immobilized, she will be able to do little more than watch helplessly as the demon moves up between her splayed limbs and begins arousing her sexually.

This particular creature is only interested in tormenting her (it is a demon after all) and so will probably start by siimply stroking and licking her entire body[,] including her sex, for several hours — more more deeply into her apex only when she is nearly insane with the need for release and literally begging the creature to take her. Demons gain considerable power when their victims willingly request intercourse.

Once it does enter her, however, her fate will almost certainly be sealed as the demon will engulf her whole nether region within its maw, wrapping powerful appendages around her hips that literally lock its phallic tongue deeply within her. Dozens of smaller tendrils lining the demons’s throat will then settle over her womanhood, coating her entire sex with a highly stimulating lubricant slime as it teases her petals and clitoris. This, along with deep thrusts of the demon’s tongue will quickly bring her to ecstasy, and will continue to do so again and again and again until this girl literally expires from overstimulation or exhaustion.
