“Shit,” he grumbled. “I don’t have a condom.”

She groaned. “Dammit, Chad.” She sighed. “Just pull out. It’ll be fine. I’m on the pill.” Amelia had been hunting him down for months now and wasn’t going to let Chad go now just because he’s a condom-forgetting blockhead. The pair had been messing around in bed for hours, and Amelia was as ready to go as she’d ever be.

Chad’s hands were rough as they undressed each other on Amelia’s dorm room bed. She hoped her beau wouldn’t mind she wasn’t wearing a bra- as if she needed one anyway. The only curves she had were all in her plump butt. A hell of a lot of guys liked that, though, thick thighs and a bubble butt, tits be damned. Amelia herself, however, wouldn’t mind her curves evening out a bit.

Amelia lay underneath him, waiting for him to finally enter her. They moaned in unison when he finally did. He wasn’t the lengthiest she’d ever had, but the thickness got the job done. Chad moved in and out, one hand on her ass, the other moving between various places, sometimes on her hip, other times teasing a nipple.

“Oh, Chad, you-hmmm-you don’t-aaahh-disappoint.” Amelia returned the favor as best she could, working his cock with her pelvic muscles. “I’m almost, hm, almost, AH, THERE!” She shouted as she came, her ministrations disrupted temporarily by her shaking through her orgasm.

“Oh, fuck,” Chad mumbled before pulling out of her just in time. His thick cock started spouting out his cum on her, forcefully, with most of it landing on her chest. He came longer than he expected to, with a huge quantity of cum now covering most of Amelia’s chest. Exhausted, Chad fell sideways into Amelia’s bed next to her.

“That was amazing,” he said between heavy breaths.

“I’m in total agreement with you there. Let’s make this a recurring event, please?”

“I’d be an idiot to say no to that.”

“Just remember a condom next time, bucko.”

“I will, I will. Trust me, getting you knocked up is not on my to do list.”

“Good- mmph.” Amelia felt a little uncomfortable, somewhat from trying to fit two people in a college bed, but mostly from an itchiness in her chest that was growing more intense.

“You okay, babe?” Chad asked.

“My chest is a little itchy. My skin must be dry or something.” She brought a hand up to her chest and discovered two things: one, her chest was literally dry- Chad’s cum was gone; two- her previously flat chest now had two B cup breasts on it.

“Oh my god!” Amelia quickly sat straight up, her swelling breasts jiggling slightly. “My tits are growing!”

“They- what?”

She grabbed one of Chad’s hands and put it on one of her boobs. “See! They’re getting bigger!”

“That’s… incredible. Holy shit.” Chad removed his hand from her and propped himself up on an elbow to watch her in the dim light. Amelia stared down at her breasts incredulously. They kept growing, gaining circumference with every breath.

Amelia felt their weight increase as her boobs swelled and swelled, rapidly growing to softball size. The itching sensation disappeared and was replaced with a euphoric feeling, a feeling of purely carnal pleasure. As her tits grew larger, the feeling grew stronger, with a slight fullness behind it.

She felt her breasts, sinking her fingers into the pliant flesh, and discovered they overflowed her hands. Her nipples were growing bigger and so sensitive that Amelia couldn’t help but pinch them and tease them. She started to moan softly as the pleasure became intensely sexual, growing louder with her boobs’ increasing size.

“They’re getting so… fucking… big. I’m… huge. Do you… like… them?” Amelia asked between moans.

“They’re beautiful. How big will they get?” Chad answered, his erection back fully from watching Amelia grow.

“Bigger… I hope…”

Her breasts obliged her, still growing, passing through cup sizes. By now they were larger than cantaloupes, her nipples like pinky tips. They grew and grew and grew, passing from big to huge. The full sensation hadn’t left her. If anything, it was getting more intense.

Amelia’s tits were close to her belly button when the growth began to slow. Almost inversely, her nipples thickened more rapidly as her breasts felt almost uncomfortably full. Amelia was shocked as she realized her boobs were clearly larger than her head.

Finally, they stopped, reaching just centimeters away from her navel. Her nipples were disproportionately large, like half inch thick nickels.

“I think it’s done, but they feel… so full. Like there’s more in them than just tit.” As her hand grazed a nipple, a feeling of wetness alerted her to why her breasts felt so full. Before she could say anything, torrents of milk unleashed from her firm nipples. Her super-sensitive nipples made her orgasm nearly immediately. Amelia’s milk flowed and flowed, covering her and her bed. The intense pleasure temporarily fried her brain, and she couldn’t focus on anything except the milk gushing out of her tits.

Suddenly, she felt something on her right nipple, and realized Chad had locked his lips around it and was sucking her milk down. “Oh, god, Chad, that feels so good, please don’t stop.” Amelia’s mind vanished into white heaven for she didn’t know how long. When she finally came to, she had stopped lactating, and Chad was releasing her left nipple from his mouth. “Did you… drink all my milk?” She asked, groggily.

“As much as I could get, babe. You taste delicious, by the way.”

“That’s… good,” she said, still not entirely recovered from her lactation. “What are we gonna do, though? My bed is soaked and I’m exhausted.”

“We can stay in my dorm. Put a blanket over yourself, it’s cold enough that no one will question it. We’ll figure everything else out tomorrow.”
