Arthur's groan is muffled into the kiss and his lips throb from a combination of that hard kiss as well as the cut from earlier getting manhandled without a care. He was already ready to blow at any second, given it's been a while since he got laid, so it's no surprise that Eames is able to get him off fast. He only laments that it couldn't last longer.

When he cums, it's with a low, satisfied moan right against Eames' swollen lips, and he spurts messily between them (damn, he'll definitely have to change those bandages-), and his body weakly clenches on the soft cock still buried in his ass. He almost slumps down from it, but catches himself to avoid putting pressure on Eames' injuries, panting hard against the man's face as he tries to catch his breath while the aftershocks keep coursing through him.
