Playing With Sex Toys With My Childhood Friend

My childhood friend is shaking from pleasure with a vibrator.. too cute! Handing me an adult toy, she asked me to teach her how to masturbate. Unable to turn her down, I decided to use the vibrator on her. But apparently her body was more sensitive than I thought.. a slight stimulation was enough to please her whole body. She was completely wet, and when I played with her chest drenched from sweat, her nipples became erect..! In her room, the restroom, the kitchen.. I'm being careful not to let her parents notice, but when I hear her sexy moans.. I can't help but do more..!! (Source: Eromangajima, translated) Note: Released as 21 episodes and sold as 5 chapters.
