Anal stretching, urine observation, tension-inducing acts, anal intercourse in threesomes, and swallowing semen orally—this anthology documents the BDSM experiences of newhalfs who, through hormone therapy, have developed feminine breasts and stretched anuses, fulfilling their desires as masochists. Volume 4 includes "Giant-Dick Newhalf Femdom Shame Orgasm, Ruka," depicting a humiliating climax scene as Ruka orgasms surrounded by well-endowed men.
