[Ultranization Lab (Urutoratofunii)] Otona no Aqua to Seichou Ecchi (Last Origin)

Aqua eagerly offers herself to the man she calls “Master,” reassuring him that they are adults before inviting him to spend the night however he likes. His touch sets off an extraordinary transformation: her breasts swell beyond all proportion, dwarfing her torso and pressing her into the mattress while her body expands into absurd, soft proportions. Aqua’s willing submission fuels the progression as he cups, squeezes, and tastes her, marvels that she barely fits on the bed anymore, and prepares to teach her more ways to feel good.
