If he can still hold that bottle while he is 'out', he KNOWS his dick is being fondled!
NOT complaining here!
I LOVE the idea!
haha, yeah...one of my college roommates was like this: I'd often go sit on his bed in his room when he was playing video games, and he'd nervously glance over at my crotch a few times before eventually reaching over and, 'jokingly,' tapping his palm against it to, "see if you're hard."
Eventually, I asked him if he just wanted to see how big it is...he didn't reply, but he did get a bit bolder when I'd pretend to be asleep next to him, or whenever we would cuddle and I'd press my boner into his butt/back
