It was one of those moments where Mimi was 'complaining' (and yeah, he knew she was joking, although the limp was legit, there was a twinkle in her eyes) that he said, "Yeah? C'mere. I'll give you somethin' to complain about then."
And he did.
This time, a clear conscience of not taking a side trip to even bothering to pause to go fish out a condom from the box and just jumping her where she stood...well, of course his intentions were above-board at that moment. They were: "I'm going to fuck you right here." And that's how it went. The "You might be sore but I'm sure I can make you even sorer" was a bit of a mindfuck, but something was missing.
The whole "I know something you don't know" portion. Which in a healthy mind of a non-asshole person is a good thing, for him it resulted (to Mimi's benefit) in lack of a "finishing move." He came, sure, but it wasn't like he used a "finisher" for her to limp off and rue the day about.
He hadn't bothered getting fully undressed, so it only took him a few moments to get decent after, and he said, "Goin' outside for a cigarette." He waited until she was out of view before opening the front door, so those walking by in the hall wouldn't get a show...
Hey. Wait. The free peep show, that might've...
Nah. He's not THAT much of an asshole.
