[It's both, really. Taking something that isn't his, being desirable enough that she'd give herself to him despite her loyalty... And Eichi isn't really 'with it' enough to realize that this is a dream. To him, this is reality. He's a lounge singer in a place where these sorts of sultry things just happen and are welcomed, and she's a (probably)married woman who just can't help but to become part of the show.

He sucks in a quick breath at her request, and then complies, pushing her down on him and lifting his hips to meet hers, his hand keeping his cock upright and hopefully at the right angle to enter her, as he's probably a little overeager, and it'd be EMBARRASSING to miss. Even if she's the first woman he's been with.]
