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...!!
