Got an idea: tiddy growth as punishment but also brain drain.
Being forced to take a pill that fogs your head and blows up your tiddies nice and fat and heavy @.@
Cruel laughter echoes in your ears, almost in perfect harmony with the moans that pour from your throat and the sound of creaking, stretching fabric. The ever-growing tightness of your bra, digging into the new, billowing flesh on your chest, sends pleasure through you, forcing you to arc your back and shove your swelling tits forward.
"Ouughhhnnn! Stooooopppp! My titties are, like, soooo biiiigggg!"
Your desperate, lewd, barely intelligible please just make the chorus of laughter ring out even louder. Your roommates just watch as you put on this lewd display for them. Cassie takes a swig from her drink and pushes off from the couch, sauntering over to you with chilling confidence. The envy you once felt for the curvy, blonde beauty is overpowered by your burning arousal; her bouncing tits make a perfect distraction as she approaches. You jump, both from surprise and a sudden surge of arousal from physical contact as she reaches down and grabs you by the chin, tilting your head up towards her.
"What's the matter, hm? You used to tell us all the time that our DDs meant we had more tits than brains! Those pills we gave you are just to make sure you know what that's really like! Now you have these oversized, lewd pornudders, just like you always wanted!"
While none of them are very long, your roommate's words are confusing, especially amid the arousal coursing through your body. Before you can even attempt a response, Cassie suddenly reaches down and seizes hold of one of your tits. Your mind flashes white. Pleasure fills every inch of your body. Your eyes roll back and your jaw drops open. Your moan trumpets from your throat but only for a second before being muffled. Cassie slams her hand down over your mouth, clamping it there to make sure you don't spit out the three more pills she just tossed in. While that hand stays firmly over your lips, the other moves to your throat, stroking it and coaxing you into swallowing the pills. You don't have any choice. The pills slide down and tumble into you. Immediately, even before Cassie lifts her hand away from your mouth, you can feel what little intelligence you have left burning away. Your tits surge, growing outward, bulging over your bra and threatening to, at any moment, destroy it entirely.
You open your mouth to say something—anything—but all that tumbles out is a series of disconnected syllables, too dumb and too horny to put anything else together. A sound hits your ears and you immediately perk up, now acting more on instinct than on any kind of coherent or intelligent thought. Your eyes track the pill bottle back and forth as Cassie shakes it in front of you. The sound of the pills rattling inside has you deeply entranced.
"God, you're so fucking dumb now! If you still had your bitty A cups, you'd still have more tits than brains!"
The laughter that comes after doesn't make sense to you. Nothing does anymore. That doesn't stop it, however, from making embarrassment burn in your cheeks, the arousal in your core burning ever hotter. You bounce your titties. You don't know why. It just feels right. It's who you are now. They're what you are. You're tits! And declaring yourself as such only makes your roommates laugh harder.
