She’s jealous of the boys

She tries to stop her imagination from betraying her, but the moment she thinks it, the Entity grabs her fantasy and draws it into focus. “Hmmm… ahh, yes… a classic…” Hermione inwardly cringes at her own hidden desires being pried into so deeply, especially this one. “This… I can work with…”

The Entity keeps Hermione and its gaze on itself in the mirror as it poses her nubile body seductively, thrusting her hips forward almost like an invitation. It smirks with Hermione’s lips as it formulates something at her crotch. She feels a spot of tingling warmth there, as it brews something eldritch just beneath her supple skin. It glows from within her, the light seeping through the thin skin like she’s shoved a glow stick up her twat.

The Entity moans, embracing the changes it’s putting Hermione through, and Hermione feels everything. The tender bubbling in her pelvis, the dripping of precum down her thighs, the knot growing in her crotch. All this comes together at once as the Entity bucks her hips, and from just above Hermione’s pussy sprouts a thick fresh cock dripping with slime from it’s gestation. A dollop of precum squirts from it already, splashing across the mirror’s surface.
