Winoa bends foward, gives Zacks' forskin a kiss goodbye, and then loops the thread around her tounge.
You watch this in confusion, and notice the thread unraveling quickly around her knees and feet. You're wondering if you should say something, but then she bites the thread with her teeth and pulls.
The tightness in your body returns, and then your dick pops like a cork, flying through the air. Winoa dodges it, and you're overcome by sensation as your hair lengthens, your tits expand, your voice moans in a too-high register... but then it suddenly reverses. Winoa looks confused, and tries to spit out the thread, but it's just wet and and sticks to her mouth.
Winoa reaches for the thread to pull it out, and that's when it strikes. The loops of thread wrap around her ankles, tying at her kness. While the thread dangling from her mouth suddenly whips around her arms and shoulders, trying her up like a harness. She pulls back, trying to stay free, but the dick thread doesn't give, and then yanks her forward. She lands face first in your flacid foreskin, grimacing as it rubs against her face.
About this time you look down, recovered from your almost-transformation, to notice her struggling against the remains of your dick. She looks up at you, "MMMF!", pleading with her eyes, but you can't do anything to help as she's slowly drawn across your foreskin. Finally, it seems like the entrance to your dick, where the strings are coming out of, is opening onto her nose, when you watch in disbelief as your foreskin distends to cover her face like a fish opening its jaw. Winowa gives a shrill scream as she is pulled inside.
It isn't painful for you, she's sliding around as the foreskin is slowly extending to cover her shoulders, and then her breasts, lubricating itself like it's never had to lubricate before. When it's finally got her good and wet, you feel your dick hole expand as Winoa's head pushes against it, and then pleasure as she rubs against your anus from the inside. She struggles all the way in, flinging herself back and forth, but pretty soon she is just kicking wildly.
You notice that it's undressing her as it's swallowing her, as her bra, dress and panties are laying by your feet, soon to be joined by her socks and shoes. But it's hard to see that past your distended belly. Your belly rumbles in apparent hunger as she gets stuck on her hips, and she tries to stop getting dragged in by curling up one knee, but your dick hole jiggles, then wiggles as it expands enough to pull in first one leg, than the other. You groan as you feel your foreskin snap tight against her leg. Still producing buckets of slime, having her smooth leg dragging across the inside of your penis just feels too good. You grab her foot, when it's almost all the way in, but the threads don't fight you;
Instead the absorption comes to a halt with most of her resting inside your belly, with just her right foot outside. But, squeezing it gingerly, you realize that the foot has been drawn in just to the ankle, the perfect amount to be covered by your foreskin as a replacement dick.
