My girlfriend, who I live with, has me fitted with a chastity belt because
she suspects me of cheating. One day, her older sister, Rin, comes to live
with us for a week because she can’t sleep due to construction noise… I
happened to see Rin after a bath and got an erection without thinking! My
sister, Rin, found out about my chastity belt. She played with my chastity
belt for fun… and that’s how my devilish older sister Rin’s one-week
titty fuck ejaculation management began! “Please lend me your breasts, big
sister. I can’t take it anymore!”
