(A.N. I'm not gonna put +18 warning signs before the smut. Mostly because most chapters will have some small amount of juicy goodness.)
After hearing Adam's promise, both the girls ate as fast as they could. After finishing they washed their dishes and headed straight for the bathroom. Albeit, Albedo had to wait for Mamako to show her where it was. Afterwards, Adam calmly finished his food and washed it. Ever since he said those words he has been fantasizing about tonight. He was going to join the girls in the bath to have some fun but as soon as he opened the door, the girls yelled at him.
"WE'RE GETTING READY FOR TONIGHT, DON'T COME IN!" They said. So, he simply waited outside on his phone. He wanted to do some research on recent events in the black market. Seconds of waiting turned into minutes and minutes turned into an hour.
Only after one hour and 21mins did the two beauty's leave the bathroom vacant. They rushed into Mamako's room before Adam could even blink. He didn't question them and simply went into the bathroom himself. He washed himself and exited with nothing but a towel. He heard many giggles coming from Mamako's room on the way to his room. Women bond over the weirdest thing.
He arrived in his room at 9pm, he simply put on some trunks (type of underwear) and lay down under the blanket. It was cold tonight, 'A great night to get some exercise in.' He thought. He eventually got tired, closing his eyes to rest. After some time, he accidentally fell asleep.
*SLUUURP* *SUCK* *SUCK*
He woke up to the sound of slurping and a pleasant sensation on his crotch. After fully waking up he looked down to see the most amazing thing he'll ever see. Albedo was doing her best to deep-throat his giant cock and Mamako was sucking his balls as if she were trying to get water in the desert. Judging from the amount of saliva and precum covering his dick he knew that they were going at this for a while.
*POP* *SLUURP*
Albedo kept sucking, the more she did it, the better it felt and the less she gagged. Mamako disconnected from his balls for a second.
"Hey honey! Don't mind us, just enjoy it!" Without saying another word, she went back into it. On careful inspection, Adam noticed that both women were wearing see through lingerie, there were outlines of lotus' on Mamako's and Rose's on Albedo, both were black. He could clearly see their nipples peeking through the gaps. Adam could feel himself getting close to ejaculation, Albedo had been steadily getting better, probably because of her instincts as a succubus, therefore he had been edging closer and closer to covering them. Just before he was about to cum, he tightly gripped Albedo's horns and pulled down. A large amount of cum flooded her mouth, however her mouth was tightly shut, the cum forced its way out of her mouth with a large amount of force and the rest travelled through her nasal cavity to escape through her nose. Adam's pelvis was covered his is own cum. Mamako once again disconnected from his balls in order to lick what she could of his remains. Albedo was coughing her lungs out, however, as soon as she finished she looking at Adam with a large amount of desire in her eyes.
Adam hadn't tested the fertility of his sperm and as a perfect human he suspected that it would be extra volatile. 'Would it even be possible to have sex with them like this?' He pondered, he wasn't ready for children just yet so this was a big concern for him. And just as he thought of this he got a gift from god.
------------------------------
Received Gift!
Reward: Skill "Fertility Control"
From: God
------------------------------
Adam didn't think twice about the use of this skill, he simply used the skill to kill the swimmers in his sperm and sat up, reading to insert his penis into the two girls. While he was contemplating his sperm, the girls had gotten up on all four and pulled down their panties. Adam now had a perfect view of their glistening pussies. Mamako had a slightly gaping pussy, however, her hymen could still be seen. Her ass was the best he'd seen and she was right next to a succubus' ass. It was the right amount of firmness while still being extremely fat. Looking over to Albedo, Adam saw a beautiful untouched pussy. It wasn't gaping in the slightest, she had been summoned here before falling in love with Momonga therefore she hadn't ever masturbated before. Her ass, although not as great as Mamako's was still a sight to behold. If not next to Mamako, he would have to praise her ass as perfect. It was fat enough to give an ass job but not too fat as to cover up any of her pussy. Face to face with such a sight to behold, Adam's penis stood up instantly. He decided to insert it into Mamako first, after all, she was his first love in this life. He got halfway through before feeling significant resistance in the form of her hymen, he quickly thrust the rest of his cock in all at once.
"Ah!" She moaned. Blood came out of her pussy, while she adjusted, Albedo held Adam's hand up to her mouth and started to seductively suck on every finger she could fit in her mouth. Soon, Mamako allowed him to continue. He slowly started to thrust, in and out. Mamako's pants and moans filled the room while her pussy tried to battle an 11 inch goliath. The more she moaned, the faster Adam thrusted, which would in turn make her moan more. With the speed of the thrusting accelerating, Adam need both hands on Mamako's child-bearing hips. Albedo allowed his fingers to exit her mouth and be placed on Mamako but she wasn't done. She got underneath Mamako's jiggling breasts and started to suck on them, with her mouth on one and her hand on the other, not to mention the increasing intensity of her pussy being invaded, Mamako's pants and moans turned into cries of distress. She was pleased beyond what her mind could comprehend.
"Stap, plees, I'm gonna die!" Mamako's words were slurring, she couldn't handle being pierced so ferociously. Ever since he started to accelerate, Mamako was constantly cumming, her juices covered Adam completely and made a mess of the bed sheets. Soon, Adam was ready to release again, although he felt no reason to tell Mamako. He simply came inside her without telling her, her eyes rolled back into her head as the cum flooded her womb. She fainted with an ahegao expression. Adam took a picture of the beautiful sight.
After getting a good pic of Mamako, he turned his attention to Albedo. She noticed his gaze and lined up her juicy pussy with his cum-covered cock. Truth was, she was quite scared of it after seeing what happened to Mamako but that didn't stop her from wanting to try it. Adam didn't give Albedo the same mercy as Mamako. He knew that succubae were experts of sex, they could handle what he was about to do to her. Adam thrust his large dick into her womb without warning, breaking her hymen. She instantly made a pained ahegao, saliva flowed down her chin and tears formed in her eyes. He slowly exited and quickly thrust back in. This cycle continued for 20mins, Adam would speed up the frequency of his thrusts every time she stopped constantly orgasming at the previous speed.
*PLAP* *PLAP*
"Ha, ah." The only thing that could be heard in the room are the rhythmic singing of the flesh as well as muffled moans from Albedo. He was using her horns as grips to continue to dick her deepest parts. Soon, Adam once again met his limit. He bit her lip and released his cum into the deepest pits of her womb. She instantly fell unconscious, just like Mamako. Once again, he pulled out his phone, he took a pic of Albedo's ahegao, and lastly took a picture of the complete mess they created. Cum was flowing out of both of their pussies, forming a waterfall to the sheets. Albedo was further decorated with cum exiting her nose and mouth. He cleaned as much as he could without waking the girls up. Soon, he hopped in between the two of them and fell asleep. All of them completely nude.
