Leo woke up in an unfamiliar room. Sarah was sitting on a chair next to his bed, watching over her little brother. His face turned slightly red when he saw his sister's thighs as she crossed her legs in black garter belt stocking. He had a wet dream last night of his sister giving him a fellatio, seeing Sarah right after he woke up from that dream caused Leo to feel embarrassed.
"It seemed like you had a good dream last night," Sarah said with a playful smile.
"Yeah… I haven't been able to dream since the apocalypse, last night was a first."
"Cindy and Mindy already went ahead to pack their stuff, let's go help them."
The rain had temporarily stopped in the morning, Cindy decided she could no longer afford to wait and wanted to move out by the end of the day. The day went by without any trouble and the young mother and daughter had settled down in the family's spacious basement room.
Catherine made a hefty dinner to welcome Cindy and Mindy to the house and Sharon took out her treasured alcohol. The little girl looked at everyone in the family with a strange light in her eyes. To her, everyone in Leo's family was a legendary figure in the future; she felt like an ordinary commoner meeting several popular stars at once.
---------------------------------------
The night had already beckoned. Leo went to bed promptly like a good boy after drinking a glass of water his sister put on the table. Catherine almost always visited her son's room every night at the same hour. By the time the mother opened Leo's door, what greeted her was the usual great tower in its full form.
Today was a special day for her, it was Catherine's marriage anniversary. Yet, she could not resist her desire and came back to her son. Recently, she started to have more frequent wet dreams of doing the deed with Leo. She once dreamed of her and Larry were having sex on bed, but as the rod pierced through her honey well, the overwhelming size and thickness were too large to be that of her husband's. She saw her husband again in her dream and the man turned into Leo; much more muscular, taller and well endowed. Orgasm during her sleep had now been a daily recurrence to her after she came out of Leo's room every night.
Leo had been sleeping completely naked for the past few days since he had torn through the undie with his erection at night. And since his body generated so much heat, he didn't even want to cover himself with a blanket. The towering mammoth was standing tall and proud in plain sight while pre-cum had been leaking out and dripping along the length of the rod.
Catherine laid her finger on the glans to scoop up the thick ooze, the amount of pre-cum alone could have put any other man's fertility to shame without mentioning the thickness that came along with it. The mother licked off her finger then proceeded to clean up the towering rod with her tongue.
Catherine was just only getting started when she put the tip into her mouth, but she felt a great tremor and visible swell from Leo's manhood. Her son was about to climax! She widened her eyes and prepared for impact. She did not have much time to think but could only thrust her head down to take the rod as deep as she could to prevent making a mess on the bed. Out of panic, Catherine used too much strength and now the gargantuan rod was completely in her throat and into the esophagus.
Because Catherine almost always utilized her breast when pleasuring the oversized manhood, this was one of the few times when she took the towering rod to the base. The powerful momentum of Leo's shots hitting the stomach was a unique sensation that will forever be imprinted in her memory. Catherine was able to fill up her stomach much quicker today.
"Why was Leo so sensitive?" After savoring the taste in her mouth, the mother murmured to herself. Now that she thought back, the pre-cum and the throbbing twin orbs were an indication that Leo had been close to ejaculation. The reason why he was in that state was unknown; but looking back at the colossal tower, it was still twitching heavily.
"Mom…," a voice came from behind the crack of the door.
"Sarah? I was just about done. Wait… why is Sharon in here?"
It had been a few days since Sharon came back from her little expedition for revenge. Sharon did not get what she wanted, but Catherine was relieved that her sister wasn't planning on going after the organization again.
"Hiya," Sharon waved her hand in a carefree smile.
"You know aunty is a big pervert, how can I not share this secret when Leo is so incredible. Sharing is caring," Sarah tried to defend her aunt in an amusing way.
"That made me sound worse somehow," Sharon shrugged in response.
"Sigh… I suppose it is a good thing. Sharon, how far did you go with Leo?" Catherine understood the benefits due to the properties of little Leo's semen; it was something that drew her back here every night as well. No one could withstand their body's desire for evolution.
"All the way!" Sharon made a fist and proudly raised her hand.
"What?"
"I went all the way with my nephew, the only part that his monster hasn't touched is my ass. I must admit I am not quite as brave as Sarah," Sharon answered her sister's question and sold Sarah out in a heartbeat.
Catherine was quite surprised, she thought Sharon would have the courage as an elder to not go to the last step.
"Well, forget about all that for now. We got a very BIG problem at hand," Sarah was kind of reluctant to explain the situation. "Well. Uhm… I was trying to prank aunty tonight and added aphrodisiacs to her glass of water… but somehow Leo ended up drinking it. Yeah, I think you saw what happened next."
The three women turned their gaze to the throbbing great tower. Pre-cum had been flowing out relentlessly, it seemed like the rod would burst anytime on its own and Leo's expression had been uncomfortable.
"Do we have enough condoms?"
"I used it all the other day, Hehe. A pack doesn't even last a day."
Catherine sighed again. Unless they wanted to clean up the mess this room would become, the three women here will be responsible for taking every gallon of thick ooze coming out of Leo's monstrous manhood and that obscene bloated twin orbs. It was the biggest predicament the family had ever faced since the apocalypse.
Sharon volunteered to go first and was the first one to fall. After quickly taking a heavy meal with her mouth, she let the gargantuan rod slide all the way in and rampaged in her womb. Her body was quickly overcome with pleasure as she was too full to take in another drop in her body and lay senselessly on the bed. Leo's thick ooze was extremely potent and taking excessive amounts would result in unimaginable pleasure beyond what the women could handle.
"Hey, don't let them flow out." Sarah quickly helped plug her aunt's gaping flower with a random toy from Leo's room to prevent any wasted food. Sharon was basically knocked unconscious for the time being and she then volunteered to be the next victim.
Catherine was bewildered by her sister and brought up something sensible.
"We could just hold Leo up and help him release into a bucket with our hands."
"Hehe, where is the fun in that? But I think we do need a bucket."
After Catherine brought a bucket to the room, Sarah was riding on Leo's behemoth in her rear end and her back facing Leo. Catherine saw the girthy rod mercilessly stretched her daughter's gaping hole and pumped even more thick ooze into the already inflated stomach.
"Quick, bring it here."
Sarah took the bucket and placed it underneath her. After a few moments, another feeling of swell came from the rod and the sister's belly was at her limit. Soon, white thick ooze started to uncontrollably flow out of her mouth. She placed her head down in the bucket and the bucket started to fill as minutes went by. Sharon then was awake and helped take the last couple loads from Sarah's mouth as she kissed her niece.
By the time the bucket was half full, Leo's throbbing tower finally calmed down to its usual level of twitching. Sharon and Sarah were performing post service to the great little Leo with both pairs of breasts and tongues smashed and mingled at the rod. Catherine saw the fervent desire in their eyes and couldn't believe how far her sister and her daughter had fallen for Leo's strong and powerful beast.
Yet, the mother had gotten a little tipsy from the show earlier and she didn't get the chance to enjoy the process due to the sudden discharge. Catherine joined the two women worshipping Leo's behemoth and took over the helm as she worked towards her second serving of the night.
It was the first time the three women saw the rod soften after an ejaculation. The erection usually only died on its own when Leo was fully awake from sleep. Tonight! Shall be a night when victory is remembered! And it shall be written in the annals of history!
Back at bed, Catherine sighed in relief. If Sarah hadn't tried to prank Sharon and caused everything tonight to happen, she might not have the chance to hold herself back today. She could imagine herself riding on her son's oversized manhood like her sister and daughter sometime in the future. The urges had been growing stronger and the temptation was a challenge every night. But for now, for the sake of her morals, she will keep holding on as long as possible.
