@Novak_Vai You honestly believe this is only their second time?
What most people seem to have missed, or simply refused to notice, is that they have been going at it like teenagers since the "incident" happened.
Sure, the first time was against the drunk MC's full will and without his sober knowledge, but that wasn't the case with the second one... nor the third one... nor the fourth one... or the entire week they spent discovering their bodies during their break-times.
So yeah, it may have began as an accident for the MC and a malefic plan for the girl, but our man has certainly enjoyed every moment and taken every chance he's gotten since Marl roped him into a relationship.
