Aoi becomes a futanari

Aoi woke up early as usual. She may be trapped in this program for a while but at least she can still swim. She had already tried swimming as far away from the island as she could but even keeping to the same direction of the sun she somehow always found herself back. A security feature Chihiro had mentioned to keep the students on the island.

This morning though Aoi was going to try something different. She may not be able to swim away on top of the water but she could try searching underwater for anything. Taking SCUBA gear and a wetsuit from the store yesterday she was not putting it on. To her embarrassment the wetsuit was made of latex rubber and oh so tight. Her body felt constricted and she could just make out the shape of her own pussy and nipples through the material but it would let her explore the ocean floor so she is putting up with it. With the SCUBA gear equipped she swims to the ocean floor. It is rather beautiful as artificial fish swim through the generated coral. She forgets her worries and enjoys her time underwater.

Eventually she comes across something even more exciting. A treasure chest! Her mind races as she wonders what is inside. She grabs the wide box and swims up to the beach.

Aoi takes off her snorkel and goggles as she looks at her treasure. "I'm getting totally fired up! Maybe it's treasure, or gems, maybe it's even full of delicious donuts!" She says in excitement. Opening up the wide box though she sees something she was not expecting. A footlong tan cock with a set of golf ball sized nuts on one end and a pink circumcised tip on the other.

"What the heck?!" She exclaims in disgusted confusion as she looks at the severed member. At first she thinks it is a dildo but everything about it is too real. Before she can close the box, the mobile member leaps at her making Aoi yell in shock. The penis lands on her face as she feels the heat from it's skin.

"Gah, it's alive!" She yells as she drops the box to bat it off her but the phallus dodges as it ventures south to her neck. The cock worms it's way into her latex wetsuit as the tight material presses the hot cock between her large breasts. Aoi grasps her bosom to try and pull it out as the penis plunders her chest by thrusting betwixt them as shudders of pleasure run through Aoi's body. The sudden pleasure distracts her long enough for the member to slip further below and she feels it's cock head rub against the top of her pussy lips.

"No, no, no! I can't get pregnant, not like this!" Asahina yells worried as she continues to fruitlessly stop it's movements. To her relief it moves past her pussy and between her legs. It stops with it's base just above her pussy and clit. She feels an intense warmth from the area. She finally decides that being caught nude is the less embarrassing option as she unzips the front of her wetsuit to easily grab the member. She unzips the long zipper down past her crotch and sees the member on her groin, the long cock unfurls and straightens out erect as if it were her own.

"Gotcha!" She says as both hands wrap around the shaft and she pulls. To her surprise she feels a rush of pleasure and the feelings of the phallus. She tries pulling a few more times but it refuses to leave her as her eyes screw shut from the pleasure. Managing to open them she takes a closer look and is shocked to find that the cock is now fused to her body with not even a seam line to indicate it isn't supposed to be there, as if she were born like this. Seeing a card that was also in the box she reads it over

"Congratulations on finding the Futanari power up! You will get a hope fragment for every person you use your new dick on or get to drink your cum. Bonus points if you manage to knock another girl up."

"No way, this can't be attached to me. I'm... I'm a futanari!" Aoi finally accepts her new reality as a hand can't help but keep stroking her new member.
