"You seem uncomfortable."
"You caught me at a bad time," Matt blushed.
"I'm sorry. I wish I could get a boyfriend like you."
"You can. You know Matt Hopper? I'll set you up with..."
"That's not the Matt I was thinking about," she interrupted.
"Uh. Come on, I'm going out with your sister," Matt was feeling very uncomfortable. He cock felt like it was going to burst out of his pants. He didn't want Lisa to see it, so he crossed his legs even tighter.
"What are you hiding down there?"
"Nothin'."
"Why don't you spread your legs then?" Lisa said. She waved her hand over his scrotum and mumbled something strange.
Matt felt a surge of pressure inside his pants. His balls started to hurt him badly. He put his hands over then as if to protect them. He could feel them pulsating. They were growing with every heartbeat. The pressure built and started to push against his crossed legs. He was forced to open them. He looked up to see Lisa smiling in anticipation as she stared between his spreading legs. It looked like two flesh colored oranges were inside of his pants. His legs were spread wide when Lisa reached over and unzipped his stressed jeans. His balls rolled out instantly as his boxers cracked under the enormous stress of his new size. Lisa then pulled his underwear and jeans off in one swift motion. Matt threw his head back and started to moan as the pressure in his sac swelled and grew.
"What the fuck is going on!" Stacy screamed. She watched stunned as Lisa took off Matt's shirt. She looked down between his legs and saw two huge grapefruit-sized testicles. His erection was way over his navel.
"Why don't you two continue what you were doing?" Lisa had an evil grin on her face. She waved her hand over her sister and muttered something strange. Stacy was being pulled between her boyfriends' legs against her will. Then, her mouth opened and she began to involuntarily lick and suck Matt's huge swollen cock. Her mouth ran up and down his shaft fast as she moaned for her sister to stop it. Matt's hips began to buck.
"So, this is why Matt likes you so much. I just wanted to watch, but now you make me force you two do it."
Lisa waved her hand over her sister again. Stacy grabbed one of Matt's balls in each hand. They were now the size of soccer balls. She started to massage them as she sucked his throbbing cock. Matt broke out in a sweat. Stacy could hear him breathing heavily. She knew he was about to cum. Stacy was forced to go faster, thrusting his apple-red cock in and out of her mouth faster and faster.
He started to seizure as the pressure built beyond his capacity to hold back. He blew his load into her head. She fought to take it all in. Her cheeks puffed out like balloons as she swallowed gallons of cum. Her moaning turned to muffled screaming as cum filled her tummy. Her belly started to bulge out of her tight cotton shirt. She stopped massaging Matt's gigantic balls and began to cover her bloated belly. Her stomach was peeking out from underneath her shirt and it started to push down her shorts. Matt stared at his quickly inflating girlfriend in shock. He was practically stuffing her with cum. The pressure pushed her shirt up so far that they could see the rounded bottom of her tits. Her shorts exploded, buttons flew across the room. She looked like she was overdue for twins. Her eyes rolled back as Matt finally blew the last of his load into Stacy's mouth. Stacy released his cock and rolled off of him onto the ground laying on her back. She appeared to be unconscious.
"She always was the skinny one," Lisa laughed.
"What are you going to do with me?" Matt said very apprehensively.
"I'm going to make you want me," she answered.
Lisa slowly unbuttoned her silk shirt, revealing her young firm cleavage. She looked over to him as she threw her shirt to the ground. Her breasts were a size or two larger then Stacy's. Lisa's nipples stuck out, showing that she was very aroused. Then, she slid her jeans down and stepped out of them towards him. He tried to get up from the couch, but the weight of his sac held him there.
"You're not going anywhere, Matthew."
She walked over to him slowly, sat down on his lap facing him, sliding his erect cock behind her so as not to penetrate quite yet. His huge hard cock rested halfway up her back, burning hot. She leaned over to kiss him, but he turned his head. She started to kiss his neck softly like Stacy had. She rubbed her fingertips gently across Matt's chest. She must have watched Stacy and him make love before because that drove him wild. She wrapped her legs around him and drove her burning hot pussy against him. He couldn't take much more of this treatment before he would have to return her affection. He stopped holding himself back when she whispered into his ear.
"I'll let you cum inside of me."
Stacy was always afraid to let him do this because she was justly afraid to get pregnant. She would always want it in her mouth.
Lisa slowly slid him inside of her, stretching herself to her very limits. She gave out a great gasp as his monstrous cock was fully inside of her. She pushed her hips back as she began to move up and down. The couch cracked as she accelerated. Her tits were gyrating as she pumped him. Matt cupped his hands around her breasts and began to suck on her palm sized nipples. She began to groan, just like Stacy did when they would fuck. Her swollen clitoris was sending tidal waves of pleasure over her. Her soft breaths turned to panting. She arched her back and shoved more of her tits into his mouth. Matt got small tastes of warm breast milk as she reached her ultimate orgasm. She screamed when she came. Large squirts of her lubricating juices pumped out of her maxed out pussy. The drops rolled down Matt's mammoth balls. She quickly realized that he wasn't done yet. Lisa tightened her cunt and caressed his dick with its tenseness. Matt suddenly became rigid. His huge balls cuddled tightly between his legs. He felt the pressure explode inside of her as he came. A huge rush of hot cum ran up his shaft into Lisa. She felt a strange warmth inside her breasts.
"Oh shit!" she shrieked.
She had forgotten the first rule of witchcraft: whatever you do to someone else will come back upon you twice as worse. She looked down at her sister. She looked like she had a beach ball inside of her stomach. She couldn't imagine two of those hanging on her chest, but just then she felt a surge of pressure. Matt leaned back on the couch when he felt the surge. Lisa let out a great moan and grabbed a tit in each hand. She could feel hot fluids fill her tits. They were far past D cups now. She threw her head back and arched her back to compensate for the growing weight. The skin became glossy as it stretched far past its limits.
Her breasts were about the size of Matt's nuts when milk began to ooze out and roll down her belly. Blue veins surfaced. They were still growing and the milk was now shooting out. The weight was too great and Lisa fell forward, smothering Matt between her tits. He tried to push out but couldn't get a firm grip on her expanding flesh. They were pushing out her arms. They looked like two over-filled trash bags hanging off of her young body. Her dinner-plate sized nipples were shooting hot milk out like a garden hose. Her skin began to whiten. It was being pulled too thin to take much more growth.
Then it stopped. Lisa could hear Matt's desperate muffled cries for help but there was nothing she could do. Just then, Matt's head popped out from in between her cleavage. He drew in a huge breath of air as his face returned from blue to its normal color. He realized that they were all freaks now: Stacy with her huge stomach, Lisa with her massive tits, and the two globes between his legs. They all rested there paralyzed in silence.
