A few alterations to Kelly's body

Kelly feels the wood nymph massage her pussy, as she plucks one of the leaves from her hair. The nymph crushes it between her fingers, and then slowly slides it inside the human girl's pussy. Kelly gasps as her pussy goes numb for a second, and then her insides begin to shift and change. The skin of her stomach writhes as her organs begin to move around. After a few minutes, the churning sensation seems to stop, and Kelly is panting for air. The wood nymph smiles at her, and then slowly slides her entire hand into Kelly's pussy.

Kelly gasps in shock, as her pussy easily takes the entire hand in. Slowly, the wood nymph slides more and more of her arm inside Kelly, until she is inside her up to her elbow. The wood nymph spreads her fingers, which stimulate and rub the inside of the girl's pussy. Kelly gasps and shakes, her body unsure of how to interprit the feelings it is recieving. Her stomach bulges as the wood nymph presses her fingers against the one wall, the pussy rubbing up against the inside of Kelly's abs.

Slowly, the wood nymph pulls arm out of Kelly's pussy, and smiles down at the panting wreck the human slut has already become. "mmmm, now you are ready for my cock" the nymph purrs.
