I can't see any signs of monogamy, just a little jealousy that was soon smoothed over. They all know he's got his bread buttered on all sides with three hot women all mixing it up with each other and him. There's only one hookup left before everyone has slept with everyone else. Then it's just down to what kinks they will get into, assuming we ever go past a little BDSM and anal. I'd like to see a line up of asses and pussy to see if he can tell them appart blindfolded. Fun games like that. And I personally think Mia will be the one to peg him, little as a suprise while he's restrained, on her live stream as she knows he's a kinky pervert. Emily can join in as a sub. Maybe Mia uses a strapon on Emily while he DPs Emily... Kinky but safe from pregnancy.
