He's nowhere close like she is. After all, he hasn't found that 'wall' yet, so he's just happily crawling about inside of her without abandon, filling her up with abundant precum as he goes, taking up all the space in her belly and then some. The bulge now grows by the second as the equivalent of at least four cocks stretches her asshole open--all he knows is that she can take more, and that's exactly what he's going to give her, no matter how close she is to orgasm.
