Vash begins to squirm slightly. That tip tickling sensitive spots as it continues to trace it's way along his body. He's not too concerned at first. This new type of teasing being erotic in it's own way. That is until Azwel starts to move lower. "Whoa!" He shouts when he first feels that tip teasing around his entrance and trying to push through.

He doesn't have a lot of free movement but still he tries to rock his hips away. Tries to move his pelvis to press firmer into the warm bed like table. "That's not how to teach patients!" Drugged filled eyes keeping him from being fully panicked lazily move back towards the camera. "In fact it's the opposite! You're going too fast!"

Not that Vash can actually stop what is happening. At first his teeth sink into his lower lip as he tries to silently bare the way Azwel starts to push inside of him. Trying to tell himself that this was better. It would be easier on his friend if for once he got to take someone rather then riding him again. Then something inside him stretches too far and nearly starts to tear as his body tries to stretch and accommodate that slowly encroaching length. A whimper escape him from the pain and he throws his head back. Shutting his eyes as he tries to ride out the painful stretching. "It hurts." He moans out softly.
