Victor wouldn't be thinking much of the touch to his arms, but the blindfold changes that. When he can see what's happening, only vaguely anticipate what he might feel next, it's very exciting. His heart thumps in his chest, not quickly but he can feel it, focus on his own body rather than any visuals. All there is is Yuuri's touch and his skin and his rushing blood. The first audible reaction Yuuri is getting is that kiss to his neck, a low and approving grumble escaping Victor's throat. His Adam's apple bobs as he swallows, curling to allow Yuuri more access.
