Seeking Sex in exchange for something

[AHSUPERSAIYAN]

Hi,
Title !
i'm looking for games with "sex trade" like getting sex in exchange of giving an object or a job

 

[Pretentious Goblin]

A lot of trainers have this as a theme, along with plenty of female-MC games with prostitution. But some games I can think of where it's a central theme and actually ties into the game mechanics:

SKA (most H-scenes are prostitution of some kind)
Witch Trainer
Karryn's Prison (bar job, stripper job)
The Lewd Knight

 

[Living In A Lewd World]

You might also try "the headmaster". The game is basically about a training a bunch of students using an education method of pain, humiliation and pleasure. The training of the students will lead to increasingly sexual acts with them, which can partly be understood as an exchange. On some spaces, you can directly decide, whether you want to be in a romantic relationship with the students, or if this the relationship should be rather formal or transactional. The game is very long right now, but there are still not much students, you can have sex with. Nevertheless it is quite good in this regard.

You may also try "Coming of Age". May does also many things for money. Starting as a shy woman, she does increasingly lewder things for and without money up til demonstrating anal sex in class (with the other male students involved) and prostitution.
