My purity ring's for small cocks only

Eva reminds her boyfriend one night of the purity ring that she got at the Bonas Brothers concert when he tries to get in her pants. Eva's boyfriend freaks out and storms off, bumping into the delivery boy and getting their supper all over the delivery boy. Eva offers the delivery boy a change of clothes from her father's closet. Eva than decides that the purity ring only applies to small cocks after finding out that the delivery boy's got a monster hiding underneath his wet jeans!
