[Yokuutsu]

Vivi blushes lightly at the teasing. Sex doesn't make him blush but apparently the teasing does. Go figure. And then to the activities. After all that, he's kind of trembling a bit. Sensory overload? He thought that wouldn't happen again period. But apparently that much activity is pushing the limits of his endurance. He clings as he's carried, nuzzling into Riyo's neck a bit.
