I love to tease my boyfriend's cock.
We spend entire days in bed but of course he's not allowed to come. All day I tease him to the point of no return before squeezing the tip of his cock very hard.
One time he started to come and a very small bit of cum came out of his cock -- so he was punished.
He wasn't allowed into my cunt for a week -- and he wasn't told when he would be allowed to cum.
