Pull back and don't allow her to orgasm

From Create Your Own Story

With a mean grin you pull back your hand. She lets out a frustrated sigh and grabs the area between her legs desperately for an orgasm. "You dumbass! I cant believe this! First you just start to finger me and now you wont even let me cum? seriously?" She looks down to the floor, playing sad. "Well" she then whispers. "If you dont want to make me cum now... maybe you will later. Meet me in the toilets in cabin 14 before school starts!" You smile and wait for the bus to arrive at school
