My girlfriend has a younger sister. Her name is Rena-chan, and contrary to her innocent impression, she has enormous breasts. Moreover, it seems that she has never had a boyfriend. I've been secretly in love with Reina for a long time. And then the day came... On the day she was away on her business trip, I attacked Rena-chan. Kiss her according to her desires, massage her big breasts, suck on her pussy and deep inside her vagina.
