"Okay, that will be five silver coins!"
The blonde busty potion seller collected the female adventurer's money and handed then the potion.
"Okay, good luck!" she said as she sat back and smiled.
Little did the adventurer know that she had spiked the health potion with her own girlcock sperm. When ingested, the potion would transform the female adventurer into a woman with a girl cock of her own, plus a few upgrades.

The female adventurer bravely fought against the Elder Lich that blocked the final treasure chest of the tomb. After defeating the lich, she paused to drink the health potions she had bought at the store, swallowing it in three swallows. Almost immediately, her body began to change. Her breasts ballooned outward, pushing her armor off her body. They continued to grow, and when they had stopped, the adventurer's breasts were massive melons that would make every woman envious. They were bigger than the adventurer's head, and the nipples were hard and puffy.
She dropped to her knees as her hips expanded out, creating a voluptuous ass on the young adventurer. She let out a moan as her body changed, gasping as a girlcock grew out of her crotch, growing long and thick until it reached a full foot in length. Her cock was even bigger than the male adventurer's. Her balls also expanded, reaching a large size that matched the growth of her tits.
Her hair had grown out, falling down to the middle of her back, and her nails grew long and pointed. The female adventurer looked at her reflection on a nearby statue. She admired her beautiful face, and her curvy, hourglass figure, with large melon breasts, and a thick bubble butt. Her nipples were hard and pointy, and she rubbed them between her fingers, sending pleasure through her body. She moaned as she stroked her long, thick cock, watching herself in the statue.
"Ah!"
