The owner of the Java Lava cafe is Mr McGee, he's the husband of your English prof, Mrs McGee. At the moment he is a happy cuckold, watching you having sex with his wife, and if you let him, he gets naked and masturbates to it. I hope he will become even more involved in the future, but I'm not the dev, so it might be wishful thinking.
Also, if you like more dicks in MC's life - Adrian is a trans woman pre-op. Undergoing hormone therapy, has grown some nice small tits, but still has her dick, or as she calls it: her clitty.
