Big sis sent to wake little bro for breakfast. After he doesn’t wake up from her normal teasing, she instead wiggles down his pissy bedtime pants and sucks him off.
Even a dry orgasm isn’t enough to wake him up though, instead just unleashing the rest of his weak bladder down her throat.
Somehow sweet piss swallowed down (must be the high sugar diet) and pull ups tugged back in place, she gets her revenge by giving him a face full of her watery t-girl cum and another hour of sleep.
