Come to think of it, I remember the Ashani drawing of Sam having sex with 3guys. That may happen with any of the possibilities below:
1. It might be a shooting for 4some on her work.
2. (This will probably answer your question) Since Liz will go to the outer branch and will stay for 1week, MC cannot go because of his work. Sam then decides to go to Liz then she comfronts Matt. Sam might be fucked by Matt and 2 other guys (probably the same guys who fucked the purple-haired MILF). Most likely Sam will agree to fuck them in exchange for Matt to stay away from Liz. This will be OK for Sam because she is already used to big dicks in her shoots so I'm sure she won't get depraved and be influenced by Matt. Also, I don't think she has nanobots that can affect her emotions just like Liz.
