GOJI-106 "Please keep me as a pet..." A manual for completely training and keeping your childhood friend as an absolute submissive masochistic pet with crazy love.

My childhood friend and first love suddenly came to visit. She looked exhausted and fell asleep as soon as she sat on the sofa, but I got aroused by her slightly disheveled sleeping form next to me, softly breathing, and couldn't help but stare. Noticing my state, she gently reached out her hand to comfort me. From that day on, a strange cohabitation began, but what do you know, she said she wanted to be my pet... Featuring two mysterious childhood friends!
