Between the water and his own strength, Vergil is able to support her weight easily by his hand alone as she leans back against it. Still, he leans in towards her just enough that there's space between his back and the wall of the tub for his tail to manifest. It curls behind her, giving Mizu something else to lean back against beyond just his hand, but snakes its way over her opposite leg along to her inner thigh.

Vergil dips his head to kiss along her throat, nipping at it lightly, and allowing her to seamlessly take the lead in teasing herself with her fingers. He's come to know her body well, and he's pleased to see Mizu's paid just as much attention when she's able to take the lead, touching and pleasuring herself in want of him. To say it's a thrill to bear witness to would be an understatement. And there is a temptation, of course, to pleasure her further beyond her touch alone to both reward and fulfill that want, but Vergil resists it for now. Mizu is taking it slower than that, and he follows her pace and movements.

"Where I would want you. Close to me," he murmurs against her skin. As close as she could be in that circumstance. Vergil returns to her lips, the languidness of the kiss mimicking the movement of her fingers. He breaks the kiss, but remains near to her lips. "You could close your eyes until it's easier to imagine it's not your hand alone convincing you to stay in bed just a little while longer. I'm right there with you."
