While you'd been uncertain as to what you should expect from this giantess, this was most assuredly not one of them. While trapped inside her bra you'd been held against the soft flesh of her right breast, which bounced ever so gently whenever she walked and swayed with the occasional twist of this massive giantess, causing the warm flesh to rub against your body. Whenever you lean your head against her chest you can hear the sound of her heartbeat, which oddly seems to speed up from time to time whenever you try to adjust your position inside of her bra.
Her scent reaches your nose and despite your position you find your body responding to its environment. You can feel your penis grow erect and press into Mary Lynn's flesh and it's a struggle just to keep control of your body throughout the day. In the end it's a struggle that you lose on more then a few occasions as you find yourself helpless to escape Mary Lynn's bra or the warm embrace of her breast.
Even as she finds herself in her home Mary Lynn still can't shake the feeling of excitement, embarrassment, and arousal as she considers what she's done. Without his consent she'd kept the tiny person trapped within her bra the entire day and while she'd been able to resist her more wild urges she hadn't been able to bring him out to apologize or even learn what he was doing there. Now she finally manages to steady herself and once again reaches into her bra gently and gently pinches the little being between two of her fingers.
The sudden change in air temperature hits you like a hammer and instinctively you try to pull yourself into a ball. Your arms wrap around your chest and for a moment you can only think of how cold you suddenly feel. Given your tiny scale though you suppose it's only natural what you would be extremely vulnerable to rapid temperature changes. As the initial shock passes, though, you suddenly remember your situation and find yourself staring back at the massive giantess that holds you between her fingers. Much to your surprise though you notice her face seems slightly flushed.
You can't handle the tension. "So what are you going to do with me?" you ask.
She clearly doesn't know how to react. She's clearly not meant to be a towering, domineering giantess. "I don't know," she says, eventually. "I don't know why I put you in there."
"Whoa," you say, not wanting to get this giantess in a bad mood. "You didn't do anything wrong. You were just having fun. No one could blame you. I had fun too." That was mostly true, too.
"Really?" she says, looking up. "This is just such an odd situation."
"Exactly," you reply. "I'm not sure how to handle it either. Let's just see how it goes. I appreciate you keeping me safe."
She nods, probably thinking for the first time about how dangerous things are for you at your size.
Eventually Mary Lynn speaks. "I'm sorry I didn't ask before putting you in my bra. What should we do instead?"
This is a real opportunity for you. You should respond carefully.
