... her areola were becoming much puffier.

With every circle around Sarah's pink areolae, they seemed to softer, puffier, bloated almost. Her nipple was unaffected, bit by bit disappearing into the swelling flesh. Within seconds, they were gone, hidden within a horizontal slit that seemed to lengthen until it reached the edges of Sarah's darkening areola. With her breasts starting to swell, Sarah began sliding her fingers along the cleft in her nipples, shuddering from the sensations shooting through her. Her cock tingled and twitched between her legs, already hard as iron and drooling pre.

Sarah closed her eyes, sighing softly at the sensation of bliss radiating into her tits, still languidly stroking her changing nipples while her breasts gained more and more mass. She didn't know how long she spent just running her fingers left and right and reveling in the feeling of burgeoning titflesh, but on one stroke to the inside, her finger suddenly slipped inside the slit. Sarah's eyes shot open - her nipples hadn't just become inverted. Instead, her fingertip was greeted by a moist feeling. She hefted both tits in her hands and lifted them so she could see her nipples better.

There on her jiggling mounds sat not the hard nubs she had had all her life. Instead, pouty lips now adorned her areola. Breathing heavily, she used one hand to pull one mouth open, and a tongue lolled out, drool running from her breast. She could actually look inside her boob; a fleshy channel seemed to run all the way inside of her. It was actually pretty deep, she realized, because her tits had swollen from modest B- to hefty E-cups.

The sight was strange, but excited Sarah at the same time. Her leaking, twitching dick forgotten, she decided to experiment with the mouths on her breasts. Opening and closing them came naturally, but more complex movements like smiling or licking her new sets of lips proved more difficult. Any movement with the new tongues, really.

The trial runs made her breasts tingle and her face flush like a particularly steamy makeout session have made her normal lips. It was then that Sarah noticed her soft gasps and moans had become a chorus - all three mouths giving testament of her lust in unison. She was unable to hold back any longer: Bending over, she began licking her cockhead with her left nipple-tongue. Since she was licking from above, the angle was weird and she could not properly lap up much precum, but she could taste it nonetheless.

Her dick twitched excitedly in response. This was so unbelievably freaky, yet felt so great. Pursing her lipples, she planted a kiss on her cock and popped it inside. The suction was even better than when Adam had blown her. She couldn't help bucking her hips upward, fucking her tit and making the soft flesh jiggle wildly. Twin moans rose to fill her room, one from each free set of lips. Of course her left lipple moaned as well, but muffled as it was by her turgid dick, this only served to arouse her further.

Her right hand hefted the other breast and Sarah began sucking on index and middle finger, her tongue playing around the digits. The feeling was indescribably good - the new lips on her bust were just as sensitive as her nipples had been and the stimulation from having both of them penetrated was incredible. Popping out her dick from the left tit and switching to the right, she continued thrusting and sucking herself off. Raising the left breast to her mouth, she began frenching herself, all three moaning voices now muffled. She could still taste her own dick on her lipple - the aftertaste of precum was delicious.

The new, bizarre feelings soon proved too much for her. Her eyes went wide and with a loud moan from two mouths, she started shooting her jizz into her right tit. Sarah could feel the hot seed spill into her, triggering a swallowing reflex she didn't know she had, then flowing through her whole boob until it ended up in her esophagus and then stomach. Sarah kept sucking with her right lipple until nothing was left in her cock, then she fell back and gasped for air with all three mouths.

This change was by far the weirdest she had experienced so far, but she loved the possibilities it opened up.
