脅迫陵辱ふたなりメス奴隷! ～幼馴染が変態チンポ娘だと知らずに片想いしていた僕の暴走～

He threatens her to make her a slave-on-command.
The girl Takusu liked was a futanari... All this time he was into a hermaphrodite...
Even though he'd believed her to be a girl, the truth made him tremble.
His distorted emotions led him to blackmail her.
She must do what he says, or he'll tell everyone her secret.
Tamaki wanted to protest, but to spare herself the exposure, she agreed.

The class, the park and the roof, it's a nonstop sadist party!
Takusu forces ever-filthier acts on Tamaki as she succumbs to pleasure!
When all is done, what's waiting for these two!?
