Dee was sitting on a bench in the gymnasium, watching Caitlyn. Really, she should have been watching her university's basketball team, being their water girl, but she found Cait's cheer routine much more entrancing. Cait was the tallest girl Dee knew, just barely eclipsing the captain of the basketball team, Tarah. The coach and Tarah both had hounded her to be on the team but she had no talent for the sport and far preferred cheer, which suited Dee just fine. Dee herself was much more plain, average height and tomboyish in dress. It wouldn't take much to guess she was gay
 
The practice wound to a close and everyone was heading to the change rooms. Cait took a few steps backwards, then bumped into Dee. What followed was an awkward few moments where they each half fell, tried to grab the other, then finished falling. The *clunk* of Dee's head earned a few "ooh"s and "yekes"s from the basketball team as they walked past, before immediately forgetting as the next joke was told.
 
Cait froze for a minute. She quickly processed what had happened, and figured out that what her ass was now framing was a face. The water girl's face. Tentatively, she looked down. The water girl seemed alright, moving but not trying to get her off. Her face flushing, Cait reached down and hooked the back of her underwear with her thumbs.
 
Dee was already blushing. Having front-row seats, she was a touch quicker to figuring out the position they were in. She felt cait slowly shifting around, and when she saw the thin cloth pass her eyes, her face turned from a slight blush to a deep red. Cait settled. Her asscheeks were engulfing Dee's face entirely, squishy mounds forming a mold around her features. Cait felt her temperature rising as carefully, she began to bounce. She looked around, and once she had confirmed they were alone, started to do so with more vigor, her speed increasing but her cheeks never leaving the shorter girl's face.
 
Dee's bright red became a deep scarlet. She was drinking up the sight, the two beautiful globes thrusting up and down as they caressed her cheeks. Hearing Cait's huffing, she decided she had to contribute somehow and stuck out her tongue.
 
Cait moaned, somewhere between oh-thats-new-and-good loud and god-im-in-public quiet; she began to slow her bouncing and instead twisted her but, feeling how the new addition felt with her movements. Before long she was rubbing her ass back and forth over Dee's head in short strokes, each time the tongue touched her anus feeling like a shot of rum in a glass of coke. She kept up the movements and slowly kneeled forward, bracing herself with one hand. While Dee gasped at the cool air, the other hand reached around and grabbed her, pulling Dee up into a half-sit.
 
Cait had started grinding Dee's face into her crack instead of moving her own hips. She aggressively pushed and pulled, Dee's mind had jumped into autopilot, just letting her instincts take over. Cait's hand kept pushing and pulling, and on a single downstroke, Dee's chin met Cait's asshole; it began to stretch. Cait's face contorted in pleasure, and she started pushing down on the back of Dee's head with a vengeance, twisting and shifting until there was an ass resting on two shoulders with long brown hair sticking straight out.
 
Dee was brought back to reality, but not before the act was complete. She took in her new surroundings, smooth and slick; she only had a moment before movement began again. Cait had taken back to bouncing, riding Dee's head like a dido. unsure of what to do, Dee lifted her hands to her unexpected partner's ass hoping to provide support, or catch her attention maybe? but didn't match Cait's rythm and they were jammed into her asscrack, pinned to their owner's neck. In the next few seconds, Cait's ass seemed to suck Dee's arms in, tightening as it rose and loosening as it fell. before long, Dee's arms were straight up beside her head, bending to the confines of the tight bowels
 
Cait had dropped all pretense of being quiet, but Hadden yet given up on not being loud. "ohh..." she twisted her hips, sending her body a short ways downward. "oh...hoohoh" she twisted again and again and was soon sitting on her captives hips. Dee wasn't sure how to describe the dark wet heat, or the position she was in at the will of the tight tube. It clamped onto her, pulsing slightly as its grip got surer and surer. Cait rose again, Dee lifted a short ways before sliding back to earth. Cait brought herself down again, then rose a ways higher. Dee did not come with her this time. Cait lost any apprehension she once had. she was rising as fast as she could and slamming down even faster. "ooohea... Ohyea... OhoHO, OOOAAAAAH" with a final stroke, Cait cleared shoulders to floor and came intensely. Dee had been uncomfortable for the last while when this sudden scream rose above the rest and the intestines around her siezed, practically locking her in place beyond the ability to even wriggle.
 
One of the basketball players ran out of the change room in just a bra and sweats and saw Cait sitting, her back to the door and skirt covering her lack of panties.
 
"are you alright? I heard you shout and-"
 
"I'll be fine" replied Cait, unable to hide the breathiness of her voice
 
"here, let me help-" the athlete was cut short by one of Cait's hands shooting back
 
"I'll be fine, just go change". The woman gave her a quizzical look, then walked back through the door. Shakily, Cait stood up. Though Her hips were lower than Cait's, Dee's feet didn't reach the floor. Cait reached back and felt the wet mess that were Dee's "athletic" shorts. she chuckled, stroking Dee a few times before pushing her upward and losing her to the gape. She clenched her asshole, gravity losing to the gentle incline of Dee's legs. Cait reached forward and down, grabbing ankles and pulling upwards. with a soft "hah" she pulled them the rest of the way, and a long push sent two shoe-clad feet between her pert and round cheeks
 
Two weeks later, Tarah pulled Leah aside at a practice.
 
"hey, have you seen Dee around? she's missed a couple practices and that's not like her"
 
"who?"
 
"The water girl"
 
Caitlin had suddenly become acutely aware of the weight in her lower abdomen she had become accustomed to. Dee was fine, she had moved around a couple times since, but she wasn't going anywhere soon
 
"yeah, I've seen her... around"
