There's a tightness in between Gwen's legs for a moment and then it's like somebody throws a pressure valve and she groans as she bites down, tastes the hot, red of blood, and between Kate's moans and her own hard breaths she realizes what's she's done.
"I'm- I'm sorry, Kate, I'm so sorry, I-"
At first its horror, etched into Gwen's crooked, monstrous face, somewhere farflung and halfway between the plucky sleuth of years prior and the thing she is now. Her blue eyes sunken away into dark hollow pits of shadow, spiderwebs veining out from her sockets, from tthe corners of her mouth.
This isn't the Gwen Stacy who fell and died and was, by and large, forgotten by the world outside of her immediate friends and family.
This was the Gwen who clawed her self out of death, who struck a bargain to buy more time in exchange for her sense of humanity.
But if she's so monstrous, why does she - do they feel so very human now, with wet warmth blossoming between their legs, with the heat of prey on their lap, stroking at their cheek. Gwen stops breathing; the Symbiote can do that for her.
"It's okay." Kate says. 'It's okay' they hear.
It's a quiet, transition, horrifying in broad light, but Gwen Stacy lunges forward, snapping her lips up against Kates, and its an ungainly, monstrous thing, this kiss - unlike Gwen's timid pecks of loping, tongueful affair. This is brutish and crude - hungry. The Symbiote shows itself, all teeth, all curves as it accentuates Gwen's physique; the sleek, shiny surface of it's symbiote skin looks as though it should stain the sheets like ink but it doesn't, and slender, feminine claws wrap around and lift Kate's thigh as they shift position in the bed.
Skin-contact with the symbiote should be lethal, even painful, but symbiosis has changed Venom, reigned in it insatiable hunger to consume. Taught it instead to indulge. Instead its a dozen little sensations for every inch of contact as Venom asserts itself, gratifies itself, and gives Kate what she wants; Gwen Stacy - all of her.
