Melissa decided that she would get back at Lisa and Melanie for getting into this. She told the two girls to get into the 69 position and start licking each other pussies. Lisa and Melanie couldn't believe they were going to get off so easily. (pun intended) As they were nearing orgasm Melissa told them to stop and take their tongues out. Both were disappointed and then Melissa told them to use their tongues on each others asses. They weren't prepared for this but nonetheless did as they were told. They were in the middle of getting excited again when Melissa told them they could go back to each others cunts on one condition. They were both so excited they agreed. Melissa told them they could both orgasm but when finished they would have to piss in others mouths. The two girls had never done anything so wild but knew they were trapped. They starting licking pussy again and soon each of them were cumming.
When they had finished Melissa said, "OK girls, time to piss."
Melissa knew her revenge was sweet when she saw a stream of piss from both cunts going directly into a waiting mouth. It actually excited her a bit to watch this as she another dare was coming.
