Faye couldn't take it anymore after watching Mary balloon outwards and needed immediate relief. She dashed to bathroom and locked the door behind her. Reaching down with one hand Faye began to stroke the 18" rod from the base to the flared head, her other hand massaging her perky breasts. Pinching one of her enlarged nipples, Faye nearly squealed from the sudden sensation.
As she continued to pleasure herself Faye felt her pelvis begin to tingle. Meanwhile, her stroking was reaching the end as pressure continued to build. Looking around the bathroom, Faye realized this was going to be big and the toilet didn't look up to the task. Finally she decided that the tub would have to do and aimed.
Her cock throbbed several times before she felt her apple sized balls tighten. Her first load splattered inside the tub as she intended, but then her cock suddenly lept upwards with the second stream splattering against the wall above the tub and back on her. With Faye's third load, her legs buckled and she fell to her knees with the length of her cock draped over the edge of the tub thanks to her increased height.
As her balls emptied into the tub, Faye felt a strange sensation behind her balls, like something was shifting. Reaching down Faye lifted her heavy sack and felt her vagina being pulled backwards.
"What the fuck?!" Faye reached behind her and gasped as something began to grow behind her. Bracing herself on the tub, Faye pointed her ass to the bathroom mirror and gasped as her vagina and asshole darkened to a similar shade as her cock sheath and both began to grow. Her asshole reshaped itself into a large fleshy donut while her vagina grew to twice it's original size.
"What the hell? I look like I have a...a...a horse's ass and vagina." Faye reached timidly toward the donut and was shocked at how good it felt to touch. She experimented and prodded the hole with one finger and then 2, all the while her cock was being woken up again.
"Mmmm, guess I'm ready for round 2." Faye wondered how she was going to take care of this many needs when she got the idea to invite some people over.
