While his girlfriend was traveling, at home with only the two of them, he couldn't resist the sight of his transgender sister's erect penis exposed through her unprotected sportswear. He then inserted it into her anus, and her spasmodic vagina squeezed his testicles to extract his semen. (Matsurei Amber MOOC-013)

A cute girl with a huge cock! Guaranteed ejaculation throughout! Mocco, a manufacturer specializing in boys', transgender, and women's clothing! The first time I met my girlfriend's older sister, she was a beautiful, busty transgender woman! She seemed to be working out; her body was very toned, and I couldn't resist the bulge of her penis peeking out from her workout clothes. I couldn't hold back any longer and directly inserted it into her anus! As a result, her sister immediately orgasmed, her anus spasming and tightly gripping my cock! What is this…! This feeling is…! Having experienced the spasming vagina for the first time, even after ejaculating, my erection didn't stop, and I was repeatedly squeezed for semen in her anus. Completely immersed in the pleasure of anal bondage that my girlfriend's vagina could never experience…!
