Me, a gangbang fan
There are a few scenes that I think could definitely do with some expansion. For example, sex in public would probably encourage one or two others to join in.
I could imagine the following.
Nude Art:
When the teacher has sex with the MC, all the participants could be asked to take off their clothes so that they can discover their body image.
According to this, one or the other student could get the idea to check out another participant or, if it comes to sex between MC and teacher, to masturbate or want to participate.
House party:
If the MC disappears for a while with one or the other guest, the background noise from the bedroom changes, someone might come to check.
Likewise, later on in the party, with enough drinks, it could happen that you don't even go into the bedroom, but use the couch straight away, even though there are still a few other guests present (who might be having a bit of fun themselves and so there is a bit of swapping).
Office - office toys:
If you are already being fucked over the desk, a second colleague could be queuing up and this situation could come to a head.
So plaything could be called in for clients to promote or seal a contract.
Regular break events to boost employee morale.
The lunch break is only 30min, but there are some colleagues waiting to relax. Fortunately, a female MC has several options.
Gym:
The shower after the workout, or as the last guest scenes with the trainer and maybe a surprise guest.
There could just as well be rape scenes if I, as the female MC, am the last girl to train next to five cock-controlled guys. Especially if the outfit is a bit more revealing.
Personally, I would also like it if there were more scenes with multiple participants.
Take the harassment scene when one is a bit lighter dressed in the bar. Why back-to-back when it could just as easily be simultaneous? Or at least there would be another scene like that as a conclusion.
