John Bush was very proud of his job with Dutton Pharmaceuticals. He had been hired right out of college as a lab technician and had rapidly advanced in the organization. Now he was the trusted senior technician for any new, highly secret, and exciting medication. The downside to that was the long hours spent in the lab.
One issue his branch faced that he was totally unaware of, was the cost savings initiatives being implemented throughout the company. Lab supplies were a significant cost to the company and reducing those costs was one of the primary goals for the fiscal year. Nitrile gloves were a huge expense and through negotiations with a low-cost country, the purchasing folks had reduced the cost by half. What the purchasing folks didn’t know, because they didn’t do the research, was that the low-cost country they selected was notorious for providing substandard goods.
John was working late in the lab and cussing something fierce at the gloves he was trying to wear. So far four pairs had torn as he tried to put them on. Finally, he managed to get a pair installed on his hands without them tearing. What he failed to notice was the small hole near the tip of his index finger. John proceeded to complete the transfer of the new drug to the test equipment. The nearly microscopic drop of the new drug that normally would have been stopped by the glove made its way to the end of his finger. Shortly thereafter John headed home for the day.
During the half-hour commute home John began to sweat from the sudden heat his body was producing. His body began to tingle, and a rush went through his groin. His penis began to inflate to hardness and was painfully pinched in his trousers. A fortunate red light gave him the opportunity to situate things a bit more comfortably, but that was short-lived. His penis was rapidly turning into a highly aroused cock. By the time he pulled into his own driveway all he wanted was to masturbate and get some relief. He couldn’t remember ever being this horny.
He walked in through the door and was met by Jennifer, his eighteen-year-old sister, who had decided a tickle fight was in order. John quickly pushed her away, his index finger brushing against her cheek as he did so. The last thing he wanted was a tickle fight with his hot little sister while suffering from a raging boner. It might send the wrong message. An honest message, but the wrong one. Holding his backpack in front of his erection he sidled his way across the room just in time for his mother Maria to waylay him. “John, come here and taste the chili. I think there is something wrong with it.”
John groaned as he entered the kitchen. All he wanted at that moment was some relief. Still holding his bag in front of his crotch he reached for a spoon. As he dipped the spoon into the chili his mother bumped into his bag and his fingertip went into the chili. He licked the spoon followed by the tip of his finger, giving it no more thought. Unfortunately, the chili was now as contaminated as John and Jennifer were. John dropped the spoon in the sink and turned to his mother. “You forgot to grind up the jalapeno peppers and add them.”
His mother grinned at him. “You’re so smart! Now help me set the table for dinner.” John grimaced. “Sorry Mom but I have to go to the bathroom right now. I’m about to explode!”
Maria thought it a bit odd that her son was holding his backpack in front of his crotch but didn’t question him. “Okay but don’t hibernate in there, dinner will be ready soon.”
John closed the bathroom door, dropped his backpack on the floor, and practically tore his pants to pieces getting them down. His cock was swollen to a size he had never seen before. It was easily two inches longer than normal and much bigger around. When he wrapped his hand around it the shock of arousal that shot through him made him groan loudly. He began to stroke his swollen cock and the feeling made his knees weak. He knew it would only be a matter of moments before he came explosively.
John leaned back against the sink and forced himself to slow down. It felt so good that he was determined to make it last a few minutes. He had no sooner settled into a nice slow stroke when the door flew open and there stood Jennifer. She quickly entered the room and closed the door. She looked at her brother’s erect cock and immediately dropped to her knees. “Oh god! I am so horny I can’t control myself. Help me, John! Please!”
She grabbed his cock from his hand and began to lick the head. “I want your cum so bad.” She began to suck his cock rabidly. John had to push her head back because her oral ministrations were almost painful in their intensity. He pulled her to her feet and their lips met as Jennifer’s hands pumped his cock. The scramble to remove clothing began and within seconds John was kissing and licking his sister’s luscious tits. He sucked each of her nipples before his lips met hers again. Their tongues danced as John lifted his sister onto the sink. He dropped to his knees and buried his face in his sister’s pussy. He began to lick and tease her clit while his finger searched out her opening. She was already soaked and soon was pulling his head hard against her pelvis. She came so hard that she fell off the sink.
John pulled her to her feet and spun her around. She leaned against the sink and presented her ass to her brother. He began sinking his cock into her as she looked at her own reflection in the mirror. She barely recognized the lust-filled face she saw.
Her pussy felt like the finest velvet to John. Lost in lust, he couldn’t believe he had waited this long to fuck his sister. Who cared about incest when something felt this wonderful? He gradually worked his cock deep into his sister. He grabbed her hips and began to pump deeply and rapidly into her.
In the kitchen, Maria had added the peppers to the chili and had tasted it. Now she found herself extremely aroused for no apparent reason. She was contemplating a trip to her bedroom to find an appropriate toy as she walked down the hall. She hesitated when she heard noises from the bathroom. She approached the door and listened. What she heard convinced her that people were having loud and enthusiastic sex in her bathroom. As she opened the door to the bathroom, she knew it had to be her own children.
The sight of her son pounding his cock into his sister brought her to her knees in the hallway. Her hand immediately went under her dress and into her panties. John looked towards his mother as she knelt on the hallway floor. He pulled his cock from his sister’s awesome pussy and aimed it at his mother’s mouth. She readily opened for him, and she began to suck his cock. One hand was in her panties, desperately stroking her clit, while her other hand rapidly pumped John’s erection. John reached the point of no return and blasted his cum down his mother’s throat. She gulped greedily, not wanting to miss a drop. The orgasm that swept over her left her trembling. Finally, her hand slowed its pumping, and she swallowed the last of his cum.
The sounds of panting as the family regained their collective breath were loud in the room. John’s cock was still painfully erect and the look of lust in his sister’s and mother’s eyes had not abated. Maria stood and grasped her son’s cock. She used it to lead him to her bedroom while Jennifer eagerly followed. They had barely entered the room when Maria removed the remainder of her clothes. She jumped onto the bed and spread her legs. “Come fuck me, son. Please, I need cock now!”
Being a good son and uncontrollably horny, John did as his mother asked. He climbed onto the bed and between his mother’s legs. His cock was swollen to the point that it looked purple as he pointed it at his mother’s wet vagina. He slid in deep and couldn’t help but note that his mother’s pussy was as velvety and welcoming as his sister’s. He began to pump deep into his mother. She grabbed his ass with both hands. “Fuck me hard!”
Happy to oblige, John began to hammer his cock into his mother. She bucked up to meet his thrusts and their bodies slammed together. They fucked like rabbits for ten minutes while Jennifer watched and masturbated ferociously. Maria exploded into orgasm and was shortly followed by her children.
The exhausted threesome lay on the bed trying desperately to recover from their sexual gymnastics. John’s erection still had not gone down but it looked a good bit less angry than it had. He lay in the middle of the bed and held his mother and sister close. His mother snuggled up against him. “Uhm, sorry in advance for the language, but what the fuck just happened?”
John was a scientist and was aware of Occam’s Razor and while the simplest answer is not always the best one, it can be a good start. Based on that, he soon figured out that something strange must have happened at the lab. The sample he was working on must have been the cause and, somehow, he had been contaminated. He explained his thoughts to his mom and sister. The room was silent as they contemplated his explanation.
Jennifer was the first to speak, “What are we supposed to do about it if anything? I don’t know what will happen when it wears off but right now, I am really enjoying it.”
Maria reached down and stroked her son’s cock. “I am enjoying it as well but if anyone finds out we’ll be ostracized. No one can know about this ever.”
John was concerned. “That presents a problem. If I am right that the lab is the cause, then the company needs to be warned about the danger. Can you imagine if this got loose around the wrong people? Just because it makes people uncontrollably horny doesn’t mean they want to be. I wonder how you both will feel when this finally wears off.”
Maria looked into her son’s eyes. “Does that mean you regret what has happened?”
“Not in the least. You are both beautiful and sexy and I love you. I fantasized about you both before this but never did anything about it because, well you know, mom and sister.”
Jennifer gave her brother a squeeze. “We have to promise that no matter what happens we don’t blame each other or feel guilty. I love you both too much to let wild, amazing, earth-shattering sex ruin our relationship.”
John rolled between his sister’s legs. “Speaking of earth-shattering sex…”
An hour later John called security at Dutton and made sure that they sealed off the lab he had been working in. It never occurred to John that the chili might be contaminated. Why should it? His mother had made it, not him. All he had done was offer some advice. The chili had been made in a five-gallon pot so that there was plenty for John to take to work for the potluck luncheon. The remainder was earmarked for his mother’s women’s group dinner.
