"Oh good you're here." Derek ushered his girlfriend into the living room. The girl walked in shyly with her head lowered. She could feel his stare following her body and groping her firm curved ass that was wrapped in the tight jean short-shorts she was wearing. Her large EE cup breasts were unrestricted by a bra and would have been bouncing freely if it weren't for the tight yellow tube top that was squeezing against her chest like a corset. Laura wasn't the type of girl to wear outfits that showed too much skin, but ever since Derek threw out all of her old clothes and replaced it with a wardrobe more suited for his tastes, it was just another regular slut uniform she was forced to wear. He had been nice enough to let her keep her bras and panties as long as he didn't catch her with any of them on when she met with him.
"Put your tits on the table." He instructed before he disappeared into his room. She looked in disdain and nodded slowly, lowering to her knees before the wooden coffee table. She pulled her giant mammaries over the yellow cloth and laid out the two giant sacks of flesh on the glossed wood. By the time Derek came back her nipples were already erect, the half inch pink nubs ripe for abuse.
He put an odd looking object on the table. They were two clear acrylic cups each attached to a hose that connected to a black box with a couple of dials and buttons on the top. He plugged in a cord that connected from the main box into a power outlet before turning his attention to Laura's breasts lying on the table. His hands reached over and squeezed fistfuls of the tender flesh in his hand. The creamy tit meat bubbled between his fingers as they dug into them roughly.
"P-please Derek... They're still sore from yesterday. Could you not hurt them so much..." The girl's weak protests were cut off by a sharp slap to her cheek.
"Did I say you could talk?" He asked sternly. "I can't believe you're acting like a bitch. I'm doing you a fucking favor by even touching these tiny things." His hands continue to squeeze the giant udders, molding them like dough. Finally after a minute of Laura's pained whines and whimpers he took time to stuff both of her large tits into each of the cups and flicked the switch that brought the machine to life.
The machine gave a low mechanic whir as each tit was vacuumed into the cups. Laura winced in pain as she felt her sensitive tits deforming and forcefully being stretched. He turned a dial on the box that made the whirring become louder, and caused the machine to suck her poor breasts harder than before. The poor girl spewed pained moans as her eyes begged him to stop the evil machine. His cold stare showed no mercy and he turned the dial completely, so that the machine would be sucking her tits at full force. Laura wailed loudly as she saw her encased breasts bloating and swelling inside the cups.
"Alright, this looks good. I need to go out and get some cigarettes and stuff. I'll be back in an hour." He picked up his car keys and left, leaving his girlfriend alone with only the noise of the mechanical box sucking mercilessly at her breasts to accompany her cries.

Derek came back in an hour just like he said he would. His girlfriend was kneeling with her encased tits on the table having them sucked by the machine, exactly where he had left her. Except now the breasts were so bloated that it had completely filled the cups. Not an inch of space was left over inside the casing. He came over and flicked the switch so that the machine slowed to a complete stop. The whirring faded and left Laura's sobbing and hiccuping behind. Her face was completely wet with salty tears that streamed down her reddened face. She shrieked as Derek pulled at the cups roughly. It took all of his force but the clear domes finally came off with a 'pop' and the two swollen sacks of meat plopped limp against the table.
Immediately she felt the air caressing her bloated mammaries. The pump had engorged her massive tit bags with blood causing them to swell and become ultra sensitive. Her tits could feel every small motion in the air, even the vibrations of Derek's footsteps pounded in her swollen lumps of meat flesh. Her breasts were now two cup sizes larger making them two grotesque GG's. They were almost too big on Laura's small frame, making them look like lewd disproportionate globes that clung stupidly to her chest. The poor girl sniffled, thankful that the machine had stopped. However Derek was far from being done with her. He brought over a red ball gag that he had just bought from his outing and stuffed it in her mouth.
"I know you get pretty loud so I was thoughtful and bought this." She could only moan through the gag in reply, but she did her best to say "Thank you". She was so grateful that her wonderful boyfriend was so caring. The light metal clink of his belt pierced her ears as Derek started to take off his belt. It was nothing special, just a plain strip of leather about an inch and a half thick. Laura watched in horror as her boyfriend wrapped the strip around his knuckles and raised it high in the air. It almost seemed like everything was moving in slow motion as the leather swung down, embedding into her tit flesh and bouncing back, leaving a pink stripe behind on her skin.
The ball gag did nothing to muffle her cries. She screamed through the gag spewing spit in the air, and a thin stream of drool down her chin. Derek raised his strap again and gave another blow to her tits with a WHAP! Laura was no stranger to having her tits beaten. Derek would actually do it quite often, but the pain was ten times more excruciating now since her tits were so sensitive. He brought the belt up over his head each time and brought it down mercilessly on the pancake mound like he wanted to pound the fleshy mound right into the wood work.
"Fucking." WHAP! "Stupid." WHAP! "Cunt." WHAP! "Making me waste my time..." WHAP! "On these stupid small tits of yours." WHAP! WHAP! WHAP! Laura's whole body vibrated with her bawling as the pain ripped through every pore of her being. She shook her head desperately trying to send her boyfriend signals that she couldn't take anymore. Despite her cries, her boyfriend continued to rain down blow after blow, tenderizing her tit meat.
It was about twenty minutes before Derek took a break to roll his shoulders, and massage the muscles in his neck. He was getting tired of using his belt and decided it was time for a change of pace. Laura was a complete mess, her chest was throbbing and bright red from the various strokes to her poor breasts. Silvery strands of drool hung from her lips and slid down to wet the lewd fun bags. Each time her saliva or salty tears would drip on to her tender skin, it would cause every nerve in her tit bags to scream in pain.
