Rumble Side Effects - 6 (Pixiv Fanbox)

Parody: One Piece

Synopsis: Chopper felt that he needed to get stronger in order to protect his friends and continue on his adventure, but he couldn't train like others. Therefore he held himself back at his clinic so he could create a new type of Rumble Ball, one that could tap more into his primal and animalistic nature. He tried and eventually succeeded, but it altered him and amplified his urges. The only way to wear off the effects is to satisfy his desires. Now desperate, Chopper chooses Robin to be his mate to do what he wants, especially after drugging her to be as lustful and irrational as he is now...

Currently Scene: Robin is forced to shove Chopper's massive cock down her throat as deep as she can and even though she has a hard time breathing, eventually she does it on her own...
