"Oh gee wiz." Melanie would exclaim as she arched her back a little bit and bent over, using her left hand to pull her buttcheek out. "My asshole is a bit sore this morning."
Alex felt the pressure of the ginormous cheeks being lifted from her tiny body as she'd attempt to pull away from the gunk which glued her face to Melanie's giant butthole, pushing against the wrinkles as long, slimey strings of brownish green sludge would connect between her face and the center of her hole.
Alex would cry, opening her mouth to scream up, hoping Melanie would hear. But as soon as she opened her mouth, Melanies other hand would rocket inbetween her cheeks and press against the back of Alex's body, firmly pressing her face back tightly against her sore butthole as Alex couldn't help but get a mouthful of her sludge.
"Oh dang. Guess my butt had a bit o' fun last night." She'd snort as she'd rub her hand along her sweaty, soiled crack, brushing Alex's body around before her pucker would flex, punching Alex's face as a loud, squeaky fart would explode through, blowing it's wretched stench right onto Alex as even more liquid diarrhea would drip onto her already soiled buttcrack.
Her hole would soon close up again, but a sludgy stream of waste would still penetrate through and slobber against Alex's face, all while the throbbing muscle would continue to pummel away, slapping her head repeatedly. Unfortunately, Melanie wouldn't even feel the abnormal bump on her asshole, but instead just shrugged it away as a lump of shit that was stuck to her.
She would bend down and pick up a pair of underwear, a G-string, although much skimpier than the one before, this one just had a quarter inch thick string which would go through her butt.
She would keep the underwear clenched in her fist as she'd open the door to her dorm, walking into the hallway as she would proceed down the stairs to the main floor as she'd approach the only functioning bathroom in the building. As the other ones had either been broken, or clogged up.
Meanwhile, Alex was in hell. Throughout the walk, she'd be viciously grinded and smacked by the bubbly buttocks which kept her lodged tight, as well as smearing the front of her body against the sore, throbbing anus which hungrily gaped and closed repeatedly, almost ready to swallow her. Alex was in panic, squriming and struggling with all her might to break free, until she threw her dignity out the window, and opened her mouth to bite down against Melanie's anus.
Melanie would let out a loud squeak as she straightened her back, her buttocks clenching as they pressed Alex's open mouth against the slightly gaping hole, all while a thin string of liquids kept squeezing through. Melanie would bend over, reaching the hand which held her underwear towards her asscrack, and furiously scratch it. Alex would feel the string of her thong rub against her, swirling around her body as she would feel the tight tug of the string around her throat, torso and left leg.
"Mnfh, fuck me. No toilet paper either. And I should really shower more often, god damn." She's giggle goofily as Alex would feel the string tug against her body, all while her front was being glued stuck to the gluttonous asshole. Melanie would retract her hand and underwear from her messy crack, and Alex was....
