[MIST-141]

My sister (or brother) who always gets failing grades because she's always having sex with her boyfriend starts sexually tempting me to lower my grades after getting angry about being scolded by our parents for comparing her poor results with my good ones. Who's the JAV actress in this video? Amateur? Name revealed!

My sisters always interrupt my studying, but the reason is far from innocent. Even when they get scolded by our parents, they somehow make it seem like it's my fault. Normally I'd push them away, but they flash their panties and touch my cock, doing perverted things that make it impossible to resist. Even though this is incest, I get turned on instead of feeling guilty, and end up letting them fuck me raw.
