[Otsumami] Misshitsu ni Tojikomerareta Futari ga Ecchi na Koto shichau Hanashi (Arknights)

Trapped in a sealed room with voices calling his name just outside, Ansel can barely stay standing as Utage teases him to the edge, her soft hand stroking him until his legs give out. Once the searchers move on, she pushes him onto the bed and rides him, heavy breasts bouncing as she coaxes him to move however he likes and admits the pleasure is making her hips give up. A nervous hiding spot spirals into a breathless, sweat-soaked cowgirl session that neither of them is in any hurry to end.
