Something happens (bra)

You remember you have a bra stashed away in your closet that you managed to buy online some time ago. The bra is big enough to fit your head in one of the cups completely, and you had fun for a while thinking about the enormous boobs it would need to fill out the bra. After a while, the novelty wore of and you stashed away the bra where nobody would find it.

You dig out the bra, lock the door of your room and slip on the bra and attach the hooks. The band size is just correct for you, but the huge cups hang loose. Not before long, you feel a tingling sensation and watch as your breast tissue starts expanding and filling the empty cups. When the growth stops, you have gained a pair of female breasts, each as big as your head. You look in the mirror and are amazed at the change. You take out the bra again and study your new breasts naked.

Both of them are perfectly shaped and just the correct size to fill out the bra. The feeling of them is surprising and a bit unnerving. You stand up and are surprised how heavy your breasts feel. You go back to lay down on your bed and think about how you can use your new body.

You grope your enormous breasts. They feel amazing, and your cock starts to grow hard as you are starting to recover from the shock of realizing whatever magic has taken over you is actually working. After a few minutes of touching and massaging your new boobs, you hear a knock on your door.

Your mom calls out through the door: "John, you okay in there?"

You reply: "Yeah, I'm fine!"

She calls again: "Come on out, you have a 5:00 appointment at the dentist."

Shit. You've forgotten all about the dentist. Your consider your options. There's no way you can hide breasts as big as your head. You don't know if wearing your own clothes again will reverse the spell.
