HUNTB-665 "Big brother, make my down there bigger with a toy..." "Okay!" "I want to have sex with my boyfriend..." My sister consulted me because her boyfriend's dick is too big for them to have sex.

A younger sister returns home feeling depressed after a date with her boyfriend. Her younger sister, who is depressed after failing to have sex with her, shows a healthy figure by expanding her pussy. I noticed that my girlfriend's younger sister masturbated like that every day... At the limit of my patience, I said, ``It's because it's going to expand and make it easier for my boyfriend's big dick to enter...'' and have practice sex with my girlfriend's sister every day! Gradually, her younger sister also woke up to the pleasure of brother-sister sex even though it was just practice... Before they knew it, brother and sister started having sex that was even harder than practicing.
