>”Oh, Aaaanoooooon!” your wife called from the bedroom.  
>Recognizing the mischief in Celestia’s voice you smiled.  
>When she said things like that you knew you were in for either a practical joke of epic proportions or sexy times of equally epic proportions.  
>And since she was in the bedroom you hoped it was the latter.  
>Stepping into the bedroom you looked around.  
>You wife was no where to be seen.  
>”Honey?” you called.  
>”Have a seat on the bed,” you heard her say from the bathroom.  
>Plopping down on the bed you told her you were ready.  
>An erotic vision strode into the room.  
>Your wife was clad in elbow length gloves, thigh high stockings, a frilly pair of panties, and her royal tiara; all her favorite sexy wear when she wanted to show off for you.  
>She had on a new accessory, however, that made you stare.  
“You, uh, let your breasts out, I see.”  
>”Mmn. All the better to show off my new top!” she cooed.  
>In public, Celestia displayed a large but reasonably sized bosom.  
>It was with rare hesitance that on your wedding night she revealed the truth: her natural bust size was actually ginormous.  
>Each divine breast was at least twice the size of her head and she used magic to shrink them down during her day to day life.  
>Fortunately she had read you aright and you enthusiastically embraced her true form.  
>After all, who were you to say no to a pair of perfect breasts so big their cup size exceeded the alphabet?  
>Right now though your wife wasn’t wearing a bra.  
>She had on instead what appeared to be a string bikini, but rather than fabric both nipples were covered by small golden metal rounds.  
>Her bulging breasts rested comfortably, pulling slightly at the twisted silken cords connecting the sun-engraved nipple shields.  
>Grinning at your dumbfounded look, Celestia twisted her torso from side to side, showing off how her skimpy top provided absolutely no support for her jiggling, wobbling tits.  
>You forgot to breath for a moment.
 
“How… How is that staying on?” was all you could think to ask.  
>Celestia giggled, “It’s magic! I used a spell to adhere them. See?”  
>Quite unexpectedly Celestia, Princess of the Sun and co-ruler of Equestria, began to bounce on her feet.  
>Her boobs responded by bobbling up and down a few inches.  
>Each time her feet landed, her tits rippled like pudding.  
>Adding more energy she shifted from one leg to another, doing a damn good impression of a naughty girl bouncing on a trampoline.  
>She seemed determined to get her breasts bouncing properly and with every hop they wobbled higher and higher.  
>Finally, she got them oscillating so wildly that on their downstroke both boobs slapped her stomach and on their upstroke they were nearly slapping her in the face!  
>Satisfied that she had made her point, Celestia stopped.  
>Even so her breasts continued bouncing for another few seconds.  
>”Ta-dah!” she said, “No slippage. What do you think?”  
>What could you say to all that?  
“I like it,” you confirmed, “But…”  
>”But?” your wife smirked.  
“But how do you take them off?”  
>Grinning, your wife minced her way over to you and leaned over.  
>Dangling her soft, massive boobs in front of your face she said innocently, “Why, that’s for you to figure out, dear.”
