Though he had a gut feeling that Grace would be a bit gung ho if he stayed in her shirt, Jack thought it better to go through another period of jostling with her than a period of uncertainty and possibly pain outside. When Jack gave his answer to Grace, she was very pleased. "I was hoping you'd say that. I won't forget about you, Jack, don't worry," the goth smirked. She closed up her shirt once more and gave her boobs a bit of a bounce, causing Jack to fall back into the crevice between the white spheres. He slowly slid a little downwards before stopping. Jack sighed. He knew what to expect. It was just a matter of time now.
Maybe twenty minutes into the class lecture, Grace kept to her word and began messing around with Jack. She casually gave her chest a squeeze, tightening her boobs' grip on her passenger. Giggling under her breath, Grace continued her little game with him for a few moments longer, shaking her chest with her hands just subtly enough not to be noticed by any student or the professor, but still plenty to toss Jack relentlessly in her bra. When Grace stopped her antics to pick up on her notes, Jack lay face down, feet up in between Grace's boobs. He couldn't see anything other than pale, slightly sweaty flesh. The warmth was growing by the minute, and Grace's heart beat was still at a fast pace. Her excitement was very obvious to Jack, but very well maintained to everyone else outside of her shirt. Jack went to maneuver himself to try and get his upper body above Grace's cleavage, rather than smack in the middle of it, but his movements only caused him to dive deeper. Grace felt this and smirked, giving her boobs a gentle squeeze from either side, sandwiching Jack a little. Not expecting this, Jack plowed face first into the side of the right boob, inhaling some of the moist flesh into his mouth before spitting it out in disgust. Grace felt this too, and giggled. "That's something to bring up later," she thought. "I'm sure he wouldn't expect me to have felt that."
After having just made his situation worse instead of better, Jack stopped moving, and so he stopped slipping further down. The pressure was a little greater where he was, with boob now on either side of his head and shoulders, instead of having a little bit of space to either side. As badly as he wanted to fix himself, Jack knew that he couldn't do a thing. He needed Grace's help, and that was an unfortunate thing to have to admit.
The rest of the class went no different, with Grace rubbing Jack about every ten or fifteen minutes. Fortunately, after the fourth bout of "fun", Grace inadvertently brought Jack back into his original position with his lower body settled in her bosom and his upper body largely free. Jack relaxed once this was the case, having just gone through some crazy albeit not so torturous conditions. He was able to rest the last twenty minutes of Grace's class without her pestering him. Once the class wrapped up, though, the giant goth immediately found some place private to bring Jack out. When he was taken out of Grace's shirt and kept on her palm, Jack was unsure of where he was at. It was dark, barely even visible. The only thing he was able to make out was the outline of Grace in front of him and the hand he was standing on. In an instant, a light turned on and the room was lit up.
Where was Jack?
