Unable to resist his aunt's unguarded, large breasts in her sportswear, he used a violent, swaying motion to thrust into her, bringing her to orgasm. Then, his spasmodic vagina tightened, repeatedly squeezing out his semen. (Wing Dance FNS-096)

[Breasts almost overflowing... a butt almost visible... can you resist...! This...!] My aunt has always been a bold person... To prepare for university exams, I stayed at my aunt's house. When my aunt started her usual muscle training to maintain her beautiful body, I couldn't believe my eyes. What kind of clothes are these... no, are these really clothes... I can almost see everything... I couldn't resist immediately penetrating her. Huge breasts, a big butt, and a vagina that was gradually tightening, swaying with the intense piston-like movements. Although I ejaculated quickly, my aunt still looked like she wasn't satisfied. From then on, I was seduced at all times, used as my aunt's sex toy, and had sex with her vagina tightening many times.
