if you still love to lick back there
Day 18
Mistress is being so cruel to our servile beauty today. She's been made to drink 3 quarts of water, then she's sent to clean the bathroom. Our poor little slave has been struggling to hold it in the entire time. Mistress won't let her even cross her legs to help her hold it in. So she squirms and whimpers because her bladder is so full, all the while seeing the toilet that she's forbidden to use until she's done.
And you have to pee very badly too. After a long teasing session from Mistress, you asked her permission to go to the bathroom. She said yes, but that you didn't have permission to pee. Your intense horniness is made more intense by the pee pressure. And the medium buttplug up you just adds to your lovely suffering.
Made to strip, you lie on the floor behind our tortured sweetheart and start to torment her further. Even though it means more time of having to hold your pee in, you just can't help caressing and kissing her lovely feet. They are beautiful, aren't they? She cries, "Damn you!" as her whole body writhes in sweet agony. You caress your way up to her pretty little ass and spread her cheeks apart as you beginning your worship of her asshole. Both of you are on your bellies, squirming in pee holding pain and pleasure. You as you lick her asshole place more weight on her bladder, adding to her woes.
Finally your hour of licking this dreamboat's ass is over. Both of you rise to your feet. Standing in the bathroom, you're both doing a frantic pee-pee dance. Mistress comes and orders both of your to stand with your legs apart, saying that the one who can hold their pee the longest will be given the chance to cum. The two of you look in each others' eyes and spontaneously lose control of your bladders. So neither of you wins.
[You did drink your glass of water, didn't you?]
