(Fay is 22 years-old with tumbles of ginger curls and huge, 32FF boobs. Her flatmate, Nadia is 23 and has 32DDs and glossy, black hair. This story continues directly from the last one, so read that for context.)

As Nadia came down from her orgasm, she gathered her wits and pushed Fay away from her pussy as she stood up. She looked down and her excitement grew again as she saw that she was right, and her busty flatmate had indeed shit in her knickers. Grabbing Fay's arm, she hauled the sexy mess to her feet, before slapping her hard across the face.
"You filthy, dirty fucking slut!" shouted Nadia, slapping Fay again. "How dare you shit yourself whilst we're fucking? How fucking dare you?!" She slapped her again, then walked out. Fay was in a daze. Her nipples were so hard they hurt and her pussy was wetter than it ever had been. Her face stung where Nadia had slapped her. She was covered in pee, both her own and Nadia's, her chubby bottom cheeks had recently been spanked and were smeared with the warm poo that was filling her panties and her mouth was full of the taste of Nadia's cunt. She felt like she was close to paradise!
Moments after walking out, Nadia was back, her lovely breasts bouncing as she marched into the room. Fay started to smile as she understood why the dark-haired girl had left, but Nadia was on her before she could react, forcibly spinning her around and pushing her in the back so she bent over Nadia's bed, steadying herself with her hands on the piss-soaked sheets. Fay opened her mouth to speak, but it turned into a cry of pain as Nadia whipped the cane across the redhead's thighs, just below the crease of her bottom.
"Dirty girl!" scolded Nadia, laying a second burning stripe across Fay's legs. The pain was intense, her soft thighs showing a hot, white line with angry, red borders. Fay's tears quickly came, but she made no effort to escape the punishment. "Using your knickers as a toilet, like a dirty baby!" Nadia aimed the next stroke on the crease below her buttocks, eliciting a short scream from Fay, who did a little dance of agony, but still remained in place, fingers squeezing the pissy sheets, tears dripping down her lovely face. Nadia aimed the fifth cane stripe across the middle of Fay's bottom cheeks, above the obscene, sagging mound of poo that was plainly visible in the pouch of her stained panties. The thin, satin material offered little protection as the cane bit into her buttocks. The sixth followed quickly, also aimed at her bottom, but thwacking wetly against the poo-filled panties. Nadia dropped the cane and grabbed a handful of Fay's red curls, pulling her upright and to face her. Their faces came together into a passionate kiss, busty bodies pressed together. Nadia was kissing her aggressively, biting at Fay's tongue, licking her tears from her cheeks, hands stroking and squeezing the younger girl's heavy breasts.
