SDMF-006 - My sister got a boyfriend, so I lost my mind and started ravaging her all over school.

Rion’s blowjob face on the bed at the beginning was cute and great, but the masked 'brother' just looks like a middle-aged guy no matter how you slice it.

An older brother driven mad by jealousy. A younger sister who resists. But in the end, she gives in. Why? Because... it's the best!

I was blown away by the fellatio. The slurping sounds were top-tier, and the thrusting was great too.

Life would be so fun every day if I had a little sister like this. I'd just keep creampie-ing her.

Izumi Rion is always cute, but she looked even cuter in this work! The scenes mostly take place inside the school. You get to see uniforms and school swimsuits. It's basically a tsundere progression; she's 'tsun' (cold) until the middle, and only shows 'dere' (affectionate) during the final scene. Because she's so cold in the beginning and middle, the final scene felt even cuter! Recommended if you like Izumi Rion!
