Masturbate (Arousal too high)

You slide your fingers into your vagina and start finger fucking your soaking pussy. Your other hand grabs at your breasts and nipples. The woman with you is too stunned to speak. You wobble over to her and beg her to make you cum. She pauses for a moment before, wrongly, thinking you are just really into her boyfriends commands. She pulls your hands from yourself, presses you against the wall and start kissing you. she then slides her hands down your belly until her fingers find their destination. She doesn't waste anytime and fingers you to orgasm in seconds. She doesn't stop however and you soon find orgasms two and three. She soon let's you go. You find yourself sated and coincidentally finished your task.
