@Desuka @Q_u_w Iirc there's also a worldbuilding reason for why Elma assumed MC would want sex after taking her on board.
It's common knowledge in their world that anytime you invite a woman/partner onto a ship, it'll lead to sex. It came from the old days when interstellar travel was long and boring, and the lack of entertainment on board. It was common for crew members to start having sexy fun to pass the time.
