But he doesn't just hear, he even walks in on the Lexi path. True they hadn't started up yet, but when she's on top of the MC purring loudly he interrupts... cuts himself off... and then walks out saying he's getting groceries and they will need more milk. I thought that was such a funny moment with him.Honestly didn't care for the Alexis or Layla sex scene because of the environment. Since the parents were home I just keep thinking fucken Zo is gonna hear and walk in at any moment. Or Adriana gonna walk in she always shows up just like Emily when you least expect her to.
And Adrianna does also walk in at times too, never caught the MC that badly though. She gets to overhear her new favorite song "Lexi's mom has got it going on..." and even sings it on the way out of the room.
Layla does the same thing to Lexi with the "I'm so horny!" moment she has with her after MC leaves. And after (first time?) Lexi/MC have sex, Layla says the entire house heard Lexi.
Enzo tells Lexi, when she introduces MC as her boyfriend, that she was never as sneaky as she thinks she was. The big implication being both him and Adrianna knew full well what's going on.
Layla's path never tries to be sneaky like Lexi, but I'm sure Adrianna was aware of what was going on in the hot tub date. She catches them making out on the couch, and even when she sees the red spot after Layla has sex she immediately goes to her to see how she's doing and if Layla was ok with it and wasn't pressured.
My head canon is that her parents have tried to create a supportive house for their adult kids. They reason the girls are probably going to have sex, so if they do they can feel safe doing it here. That way they aren't put into any uncomfortable or awkward positions, or feel forced/coerced. They have a safe space to operate from. If that makes sense?
