[Harumachi Tsurara (Nayoi)] Superficial Lovers [Shiromaru]

Rio gave up everything — job, home, family — to be reborn as the perfect girlfriend for the woman she adores, and the two lose themselves in each other with eager tongues, pumping fingers and grinding hips, every shuddering moan dripping total devotion. But the bliss is engineered: Sae herself fabricated the supposed gender swap, erasing Rio's original personality with syringe after syringe until the devoted lover dreaming she was once a man became exactly the partner she wanted. What starts as breathless cunnilingus and scissoring heat curdles into a cold confession, a bound captive strapped to a chair screaming murderer as Sae calmly cuts her final loose end.
