EBWH-134 For some reason, my fair-skinned, big-breasted childhood friend keeps hanging out in my room, and in exchange I'm allowed to treat her like a sex toy - Aya Nakamura

Aya-chan is my old classmate. Unlike me, an otaku and unpopular girl, she is a gal with the best looks in our grade. I thought we had no more contact, but one day, Aya-chan called out to me. Hey, can you lend me your room now? You know that I have a problem, right? If you lend me your room... you can have sex whenever you want. My hips don't stop moving in this amazing lucky pervert experience that only happened with a childhood friend... but what is the special feature of Aya-chan's sex...?
