Chapter Three: Watersports

Maud didn't let up with the whip. She brought it down on Pinkie's flank again and again, until she was satisfied. "Now, Pinkie. When I tell you to not make any noise next time, what will you do?" She whispered in Pinkie's ear, softly stroking her flank.

"S-stay quiet." Pinkie moaned, her marehood now quivering with need.... And something else?

"I noticed you drank a lot of cider at the party, Pinkie. I also noticed you didn't choose to use the washroom before we started our little game." Maud said, taking off Pinkie's blindfold, using her hoof to push around Pinkie's bladder as Pinkie attempted to squirm uncomfortably. "What's wrong, Pinkie Pie?" Maud asked teasingly.

"N-nothing!" Pinkie's eyes widened and she gasped as Maud began to massage her over-filled bladder.

"Are you sure?" Maud raised an eyebrow and pushed hard on Pinkie's bladder. Pinkie yelped and squirmed.

"I-I-I have to pee!" Pinkie gasped.

"Oh, Pinkie. What am I going to do with you?... Or I guess, what am I going to DO to you?" Maud grinned, turning Pinkie on her back and pressing her hoof on top of the pink ponies' bladder. Pinkie squealed as she felt the pressure on her bladder, feeling like she was going to burst.

"M-Maud... P-please..." She whimpered, wiggling around.

"Please what?" Maud said, pressing harder on the poor party ponies' bladder, pushing her to her limit.

"Please stop! I'm going to pee!" Pinkie moaned. Maud looked at her, and then left the bedside and came back, holding something in her hoof that Pinkie couldn't see.

"I don't think so." Maud said, shoving a huge vibrator into Pinkie's dripping marehood.

"Ahhh!" Pinkie moaned as she felt the vibrator turning on, full speed. She tried desperately to hold in her pee but she was so close to losing it all.

"Pee, Pinkie." Maud said, thrusting the vibrator in and out of Pinkie. Pinkie bit her lip and shook her head. Maud thrust the vibrator in and out faster and faster. "Now, Pinkie. Don't make me ask again." She hissed, as her hoof snaked in between her own legs, playing with her marehood, and tickling her clit. She was standing right between Pinkie's legs.

"Ahhhh! Maud!" Pinkie moaned loudly as she felt herself lose control of her full bladder, her warm fresh piss shooting out and all over her sister, drenching her in a warm golden shower. Pinkie moaned and squirmed, the release of her bladder too much for her, as she felt her orgasm, the force of it causing her piss to shoot out even harder, leaving even Maud's mane drenched in the warm golden liquid. "M-Maud!" She moaned louder, feeling her inner walls convulse around the vibrator.

"Yes, Pinkie. Let it all out." Maud said, the feeling of her sister's piss drenching her making her marehood drip, leaving a puddle of her juices on the floor. She began to rub her marehood harder, feeling her own orgasm grow closer. "Ohhh Pinkie!" She moaned, her marehood squirting as her orgasm hit it's peak, her inner walls clamping down on her hoof.

"Maud, I love you." Pinkie said sleepily, as her orgasm faded, leaving her breathless and tired.

"And I love you too, Pinkamena Diane Pie." Maud said, breathless herself, as she climbed onto the bed and kissed her sister deeply. "Let's get some sleep. Tomorrow it's your turn to be in control." She whispered in Pinkie's ear. Pinkie smiled and kissed her, and drifted to sleep. Maud followed soon after, both ponies exhausted after their 'sisterly love session' as they called them. They were fast asleep in the bed, which was now soaked with Pinkie's pee and juices from her marehood.
