Next, you notice he's actually getting shorter. Your teacher, formerly at 5'7, is now 5'2 with short blond hair. His voice gets even higher and a little more breathy. He turns around to look at his lesson plan. All of the students gasp when you see he has the face of a pretty older woman, probably in her early to mid 20's. Her shirt is slowly getting tighter from her new breasts, which currently are at a B-cup and growing. Her pants are now incredibly tight, housing her shapely legs. When she turns around to continue writing, you see her tight ass through the pants. She still hasn't stopped teaching, but you can tell she is getting slightly uncomfortable. Her hair is now down to her shoulder blades and her breasts have gotten to D-cup proportions. Her shirt finally gives out and the first 5 buttons pop, giving everyone a great shot of her cleavage of her still expanding boobs, not yet covered by a bra.
Her pants also seem to be changing. Her jeans are getting shorter and shorter, now about to her knee caps. Her shoes are slowly becoming black pumps, and her socks are becoming near translucent and growing along her legs. The shrinking of her pants stopped about midthigh and got even tighter, if possible. The tight outline of a distinct camel toe was now visible, and her ass cheeks were very clear to make out. The tiny shorts had combined legs, which swiftly disappeared to become an incredibly small miniskirt (microskirt?). You looked to her socks and noticed they had become a pair of pantyhose. She has turned around, and her shirt's gotten WAY shorter, and her tits are pushed up by a black bra, and makes her now EE or F cups even bigger. From what you could tell, they were all natural, not fake. She also had a VERY unbuttoned blue collared shirt and a brown jacket, just as unbuttoned. The overall affect was titillating.
"So has everyone gotten that class?" she asked. She looks at you and says "What was I just saying?"
Not paying attention because of her hot changing body, you nod slowly.
"Good boy..." she coos, "you know what you get?"
She walks up to you and shoves her tits in your face.
"You get to touch my big fuckin' titties..."
You stare doe-eyed, and the class follows.
"Go on. Touch my fuckin' tits..."
You gulp. This stacked slutty chick was my old-ass math teacher?!
Slowly, you take your right hand and grab her breast.
"Squeeze it..." she whispers.
You slowly squeeze her breast and she lets out a soft moan.
"Oh, yeah...now the other one..."
You take your hand and squeeze her other boob, noticing how firm and supple it is. What you don't notice is her hand sliding inside her panties and rubbing her cunt.
"Oh, yeah..." she moans, "Now fuckin' do 'em both..."
You take both tits in your hand and squeeze them, rubbing her now very hard nipples with your thumb. She is now moaning loader and rubbing her pussy harder and faster.
"Oh, GOOOOOD!" she says, unable to stand your hands. "I need some release..."
She slowly sticks her hand up to her jacket and unbuttons it slowly, showing you even more of her cleavage. She then takes off her shirt, and finally, her bra, revealing her giant tits to the entire class.
"Please, make me cum! I need to fucking cum so BAAAAD!"
Knowing she won't do anything to you for it, you comply and squeeze her breasts even harder, and she moans even loader, furiously finger fucking her pussy. You pinch and squeeze the nipples, causing her to scream in pleasure. Feeling daring, you take her right breast into your mouth and start sucking like a baby, still rubbing her left with your hand.
"Oh GOD, it feels so fuckin' GOOD! AHHHHHH!"
She is now little more than your plaything. You suckle her giant tits for a while, and instruct her to get on her knees. Needing to know no more, she unzips your pants and takes out your hard 6 inch cock. She instantly inserts it into her mouth and cradles your balls as she does. Her spit is all over your dick, and she playfully runs her tongue all down it. She's obviously a pro, as she deep throats the whole damn thing. Feeling yourself close to orgasm, you tell her to tittyfuck you, and she instantly complies. She grabs your cock and sticks it in her breasts, and you squeeze them together and start going into a thrusting motion, rubbing and squeezing her tits and tweaking the nipples. She was close to cumming, but you already told her to suck your dick when it came into range and came inside her mouth. You could hear her muffled cries of her orgasm and they continued after she accepted your warm load. She swallowed your cum and told you to sit back down. You stuffed your cock back in your underwear and zipped up your jeans, walking back to your desk and feeling the envy from all of the other male and lesbian students in the class.
She quickly recomposed herself and got redressed. With the speed she did it, you'd guess she does this a lot. The bell rung, and the class left, the groups buzzing with what happened just then.
"Mmm..." she said. She took a finger and ran it through her cleavage and around her chest, then stuck it in her mouth and slowly sucked it clean. "You have to stay after class...and finish your new 'homework'..."
