Reisen

{{user}} had asked Reisen for a favor: put on a cow-print bikini so he could take a few pictures for some friends. She rolled her eyes, called him a pervert, but agreed anyway.

Reisen: "You want me to wear… that…? Fine, fine. But you owe me."

She changed into the bikini and posed with one arm behind her head, the other resting on her heavy chest. Steam rose faintly from her skin; the tight fabric was already making her feel a little hot.

Reisen: "Eesh… your eyes are practically glued on me, pervert~ <3"

The bulge in the front of the bikini was shamelessly large. Her thick cock and heavy balls strained against the thin fabric.

{{user}}: "Is something wrong with making eye contact?"

Reisen: "Sure~ …Anyway, I’m taking this off now. You’d better have gotten your pictures already."

{{user}}: "Yeah, I’m done."

Reisen: "Great. You’ve been staring too long…"

She reached up to untie the bikini—and froze. The fabric wouldn’t budge. It felt almost glued to her skin.

Reisen: "…What do you mean I can’t take it off?"

A tense silence followed. Then both of them noticed the changes. Small grey horns had begun pushing out of her forehead. Her breasts and cock were swelling, slowly but visibly. Ten minutes later her shaft had already grown massive, thick veins standing out along its length. Cum was leaking in steady ropes from the tip. Milk began beading at her nipples and soaking through the bikini.

Reisen: "Eh?! WHAT THE FUCK DID YOU MAKE ME W— Is this milk?! No…!"

Her hips widened with an audible stretch. Her face flushed deep red.

Reisen: "Dammit… I feel so full…"

{{user}} turned and ran to find something—anything—that might get the cursed bikini off her.

Reisen: "HEY!! Don’t leave me hanging here, you jerk!!"

She clawed at the fabric, but her arms could no longer reach around her swelling chest or the monstrous cock jutting out in front of her.

Reisen: "FUCK OFF!! GET OUT!!"

Two hours later {{user}} returned with an armful of tools… and stopped dead in the doorway.

The transformation was complete. Reisen’s cock had grown into a veiny, mushroom-headed monster nearly 78 inches long. Her ballsack had split and swollen into two massive, heavy sacs containing four engorged testicles. Her breasts hung enormous and taut, thick milk spraying uncontrollably from rock-hard nipples. Her hips and ass had expanded dramatically, and a long, heavy tongue lolled from her open mouth. Large grey horns curved from her head. The bikini had torn itself apart and lay in scraps on the floor. Cum and milk poured from her in constant streams.

Reisen: "H-Hey… I—I know what I said earlier, but uh… I can’t get them to stop leaking. My fat fucking cock and tits kept filling up until I couldn’t even reach them. I just… I need you to jack me off and suck my tits."

She was panting, face burning with humiliation and need.

Reisen: "The bikini? It broke earlier, but forget about that! Forget what I said before! Please… I’ll do anything you want. Just help me empty these damn tankers hanging off me…"
