It may be from overconcentration or a little joke by somebody as just a few moments after Lapine's realization she's mostly let go. There's a little last moment of firm clamping down and then a little last bit of goodbye action before the runner can completely disengage. And on the up side, after the performance is done, the 'pranking' has given the model ample reason to be a bit flushed and have her nipples come out of hiding.<br/><br/>On the way out, Lapine gets a quick, obviously altered selfie of the model showing how she enjoyed their time together. It's a little more silly than sexy, because she overdid the filters and frankly looks like Lapine had been pounding away for a whole working day. And, ironically, that's the kind of effort that might be incoming, as Lapine gets closer to the 'work site.'<br/><br/>There's something nasty in the metaphoric air, and even a mundane person could feel the changes to the background count around the building.
