[Echigoya Takeru] TWINS complex (Nyotaika Heaven) [Gentletemptl]

A twin sister doses her brother with a medicine that turns him into a girl, and his panicked disbelief at a body suddenly heavy with breasts and wide hips quickly gives way to something hungrier. Bent over and taken from behind in nothing but thigh-high stockings, he swears it is a one-time thing even as he huffs and trembles through every thrust, while the scheming sister who started it all smugly notes he listens so much better in this form. What begins as a drugged ambush ends with him transforming on his own will, squirting and slinging insults through a bickering, breathless finale that leaves both twins tangled and spent.
