Vash cries out in the occasional grunt of pain, but it's exactly what he wants. That throw from pleasure and pain that makes it too hard to focus on just one. Every time his thoughts start to get settled their thrown in a different direction.

The glow to Azwel's skin might have startled some, but Vash loves to see it. Fingers touching and spreading themselves across those lines. A reminder to the outlaw that it was okay he wasn't human and that there were plenty that weren't. Even those who were human were most of the time something even more.

His body begins to tighten around the cock buried inside of him. Savagely his hands curl into whatever bit of flesh they were currently on. Vash's head snaps back so quickly it's a surprise he doesn't break his neck. A completely primal shout escapes him as his orgasm rockets through what feels like his entire being.
