It's time for a theory again.
You may have noticed that Josy applied lotion during the first sex in EP7. If not see spoiler. At the edge of the running down sperm the actual skin color of Josy comes to light. Also, the glans from the MC looks dyed somehow.
I have three theories about this.
1. (Twins) In the flashback of Josy and Maya, Josy says that she once sold Strawberries. Thereby she sat in the fresh air, could listen to music and got nice brown. Maybe Josephine put on some tanning lotion to fool the MC.
2. in EP5 we learn from Sarah that there is a Crabs lotion. Does Josy perhaps have Crabs? If so, from whom? Arieth is a possibility. In Ep5 Hangout we learn from Josy that Arieth wants to teach Josy everything. In EP7, we see a dildo on the wall in Arieth's room. Derek is a second possibility. How now Derek? Don't worry, Josy didn't, as far as I know, fuck Derek. Derek didn't fuck with Arieth either. But in EP4, when the MC is sleeping at Derek's, you can see shaving cream and a razor on Derek's shelf in the freeroam event. Derek asks the MC once in the gender studies whether he prefers a shaved or hairy pussy. In EP5 Josy explicitly says that she has just shaved. In the Freeroam event, the MC can also kick Ron the Peeping Tom through the door. Then a guy runs after Ron and Arieth is suddenly standing in the doorway. What if the guy or Arieth once borrowed Derek's shaving kit. Unofficially, of course. After that, maybe Josy used it.
3. I looked at the sleeping behavior of the LI's and the MC. I noticed that Sage sleeps to the right of the MC, as does Jill. Josy sleeps only once to the right of the MC. And that is in EP4, when all three (Josy, Maya, MC) sleep in one bed. Maya always sleeps to the left of the MC. Since I'm not a Bella fan, I don't have Bella's sleeping patterns in mind. In EP4, when the MC goes to sleep in Maya's bed, there might be a clue that could give away what might happen while she sleeps. There is a difference between screenshot 1 and 2. A small white spot. See spoiler.
In Ep7 after the party, Josy and the MC have sex. Josy is lying to the left of the MC. The MC has his eyes closed the whole time. I thought at first Josy was too. But after I increased the exposure, I could see that Josy had her eyes open at least once. Josy also thanked the MC. The MC says that he feels really rested. Did he perhaps not get that he had sex with Josy? Is the MC instead of a sleepwalker a sleepfucker? What I also find strange is that the MC also woke up very rested before meeting Josy at the gym. Did the MC perhaps have a visitor during the night? Maybe that explains Josy's lotion in the first sex scene of EP7. Did Josy maybe want to find out if the MC fucked Maya the night of EP4 while he was asleep and therefore rubbed lotion on her body? Maya was lying to the left of the MC. But what I also wonder is what if someone is lying to the right of the MC while he is sleeping? Jill took the MC's hand between her legs. But the MC was not asleep. Sage was not lying right next to the MC, she was lying on the bed and the MC was lying on the floor.
