They stayed like this for a long time, appreciating each other's warmth. Once Rona finished having her chance and draining Garnt's balls, Unami mounted him and shook her hips without giving him a break. They were more than aroused to see the other girls observing them having sex and it added an extra layer of arousal.

[You really need to be careful. If you let them, they would even crush you under their boobs. These girls are too strong and energetic.]
Eva was worried, but she knew Garnt wouldn't end up losing to them, after all, he was still erect after all this. He got up feeling his back aching and looked at the other girls, who were already lying at the edge of the hotspring exhausted.
