[Taketombo (Naba)] Yukarin ni nattara (Touhou Project) [desudesu]

A curious boy accepts a gap-youkai's playful offer—'would you like to be me?'—and wakes up trapped in Yukari Yakumo's luscious body, stunned to find her enormous, soft breasts dwarfing even his own mother's. One guilty squeeze snowballs into a breathless exchange as he puts his new voluptuous frame to work, smothering a throbbing cock between those massive tits and savoring every taste until his partner can barely hold back. The climax erupts in a spectacular cumshot that leaves Yukari's heaving, sweat-glistened chest thoroughly glazed while the boy-in-her-body melts into a tongue-out, cock-drunk daze.
