I think he'll bottom, myself personally. Yes, he COULD top, but i think he leans more towards a bottom. His body's super sensitive, he always plays the passive role in sex, he moans and pants while the blonde keeps his composure, he tends to be physically underneath the blonde, he's pretty, etc. As pointed out above, he had a vibrator used on him. Sure, it didn't go in his ass, but it's a hint. He gets swept away too much to be the top. Though the blonde HAS had an unfair advantage so far with him being drunk and then drugged. MAYBE it'll do a 180 and make him a lot more aggressive next time if he's sober, but i think the direction this is going is that the blonde is making him into his bottom. He's pleasuring the masculinity out of him, making him moan underneath him to get him used to it.

As a side note, hot that he's trying to bag a straight cop, i wonder who's what role? The cop is pretty and put into defenseless situations a lot, so i think he'll be bottomed, but he's also a manly straight cop so i could see him topping. Who knows?
