RPGM Energy Drain ~Otoko no Ko Targeted By Futanari Girls and Succubi~

Energy Drain is a Japanese-game RPG set at Saint Demi Lune Female Academy, a maiden academy attended only by futanari magical creatures. You play Noa, a cross-dresser secretly enrolled while helping classmate Karen relieve her sexual tension, until an event drags him into a string of compromising situations.

The 2DCG art and 2D-game combat lean into a classic JRPG framework, with censored Japanese-style scenes and a maso-leaning male protagonist arc. Futa/trans, female domination, footjob, rape, and combat-tied encounter design all factor into the loop, with no role reversal and a strict female-dominated framing throughout.

If you want a classic Japanese futanari academy RPG with a femboy-coded male protagonist, succubus-and-futa enemy mix, and a male-masochist target audience, Energy Drain commits to that exact niche from start to finish.
