Succubus Contract II v.4.0

This is the sequel to the game Succubus Contract.
The story continues after the MC in the guise of a girl loses consciousness.
You play as the MC, who previously, without realizing it, signed a contract with a succubus. Of course, the succubus hid all the details and specifics of their "contract" from the MC and passed it all off as an ordinary kiss. But that kiss, completely changed MC's life and turned him into a girl. After our MC had come to terms with his situation and was already used to his new body, the succubus visited him again. But this time the succubus came with more serious intentions, to involve the MC in a life of lust and debauchery. The succubus was very serious and set new rules for the use of the body, for the MC. Now the MC must drink sperm or pill to keep his female genitalia, and if he does not, his female genitalia will be replaced with male genitalia and he will become Futa. But, what if, once again, this succubus is hiding something..?
