My childhood friend always sneaks into my room and reads comics and magazines! While she is dozing off, I secretly insert a vibrator into her vagina so she doesn't notice! When she wakes up, I turn it on right away! My childhood friend doesn't know what's going on, but she trembles and feels it! "What's this? Take it away!" I have no choice but to pretend to take it away, and when I turn up the vibration and stir it with my fingers, she cums so much that she's in heat even after the vibrator comes off! We ended up having sex!
