MKON-022 - My sister became a student teacher and protected me from the bullies

Since she gets caught while her brother is passed out or they have a 3P when he's not around, the NTR vibe felt pretty weak. Still, the way she falls into pleasure during the final 3P scene was quite erotic and good. Above all, Nozomi Arimura's cute face, curvy lower body, and her perky nipples were so hot; I felt like the work was carried entirely by the actress's charm.

If they were going to include the younger brother, I feel like they should have had more scenes highlighting a pure, affectionate bond between the siblings. It's tagged as NTR, but I felt the actual sense of being cuckolded was pretty weak.

Based on the title, I expected a story about a student teacher protecting her brother, but the plot would have worked just fine without him. I wish they had leaned more into the 'strong-willed sister protecting her brother' dynamic. That said, watching her get violated by thugs and slowly succumb to pleasure wasn't bad. It could have used better pacing, but seeing her lose control while drooling was definitely erotic.

*This is the first time I saw this actress in this work...Does she look like Kasumi Arimura? Great body and reaction! I fell in love with it! The way the nipples stand, the way they react when you cum, it's so cute!
