I stared at my teacher's tits and felt my cock throb in my pants. The whole voyeur thing thing had been fun, but her stripping off to show them to me was a whole different level of sexy. She had goose bumps all over, and some red marks from table I guessed. Her nipples were all crinkled up again.
"Hello? Earth to Joe?" Miss parks held her hand in front of her chest and snapped her fingers. "I can't care if you stare but it's rude not to talk to me."
I shook my head and blinked a couple times before looking her in the eye again. "What? Oh, yeah, they're pretty awesome. Want me to make them bigger?" I watched as she tried to frame an answer, opening then shutting her mouth.
"No!" Miss Parks spat out, then stopped and gnawed on her lip some more. "Well, not permanently, then I'd have to buy new clothes, but if you made them shrink back to normal before you leave I'd like for you to do that to me."
"Really?" My voice squeaked a bit I was so surprised. I blushed and kept talking as if I hadn't just sounded like some dweeb. "I mean, I guess you can't lie to me, but why?"
"Joe, I know sex-ed only covers the basic mechanics, but surely you've explored a bit on the internet? I told you earlier I've got a thing about being sexually submissive; that means I want you to do things to me because you'll be doing them, not necessarily because I want them." She got a pained look and blurted out a last sentence. "Actually, the less I want something the bigger the turn-on your doing it will be."
She got up from her chair and stood bent over bracing her hands against the table top. She hung her head, her hair falling down to hide her face. "Whenever you're ready Joe."
"Miss Parks--"
"Cathy. My name's Cathy, no reason to stand on formality when I'm standing half-naked in front of you."
"Um, Cathy I wish your tits were bigger." Miss Parks moaned slightly as her breasts expanded. It was hard to tell how much from the way they were dangling, but it looked like maybe a couple cup sizes. They were at least as big as some of the girls' I'd seen online.
