Adam Roth was standing in his backyard, surrounded by his relatives. Today was his mother's birthday, and his family had come over for a cookout. While he was joking with his cousins, and getting his cheeks pinched by his aunts, he was trying to keep his mind off his hot, pregnant girlfriend...and her hot mother.
He was helping himself to some chips, when he heard his mother's voice behind her saying, "Adam, look who's here!"
Just as he had gotten himself into the celebration with his family, he wheeled around to see his mother escorting two females into the yard. Adam recognized them at once: it was Katie and her mother, Martha. Even at three months into her pregnancy, Katie was extremely comely; she had long, golden hair, a full bosom that was well displayed in a pink scoop neck shirt, well-rounded hips that were covered in blue jeans, and bright blue eyes.
Her mother was equally beautiful, with her waist-length hair that was elegantly arranged in a braid. She was dressed a lot more conservatively, wearing a white, long-sleeved turtleneck blouse, and a denim dress. One might have confused her with a woman from a Fundamentalist Mormon community. She had a very stiff expression on her face, as if she had just walked into a church. Despite her austere appearance, Adam knew her so much better.
As he gazed at Martha's modest top, he thought of the large, round breasts that were confined within it. His gaze made its way down to her dress; he knew that underneath, Martha Ridley concealed a massive penis, which he had seen numerous times. Fortunately, she also had a vagina, which Adam had enjoyed, as well.
He and Katie had started dating at the beginning of the year, and in that time, they had started a very intense sexual relationship. He would never have imagined that her mother would be in that relationship as well. For, despite what any of his family members could see, Mrs. Ridley in truth was a sex-hungry futanari.
"Hey, baby," Katie said, as Adam came forward to hug and kiss his girlfriend in greeting. "Thanks again for inviting us."
"Yes," Martha said. "Unfortunately, we can't stay too long; Katie needs to get home and rest."
"Well," Adam's mother said. "It was nice of you to fit us into your day. Please, help yourself to some food, while you're here. Adam, make sure you introduce them to everyone."
"Sure thing, mom," Adam replied.
It was strange to think that only a few weeks ago, they had spent the entire Spring Break confined to the Ridley residence, satiating their lusts with each other. A stream of images came into Adam's mind, reminding him of all the shameful, licentious things he had done to the two females that he was escorting around his backyard. He fought to suppress the memories; now wasn't really the time to be thinking of such things, but it was difficult.
As Katie kissed his grandfather on the cheek, he imagined how those same lips had been wrapped around his dick many times. When Martha shook hands with his Uncle Mort, he thought of how those same fingers had repeatedly grabbed his balls. He caught his Uncle Rick telling Katie a dirty joke that had her laughing madly with her eyes shut, the same expression had been seen before, except she had been naked and bucking up and down on his lap.
This was torture: seeing two women he had treated like whores interacting with his family members. He couldn't look at both of them without imagining them mid-coitus. Adam mused at the irony of his dad cooking bratwurst sausage on the grill, and how they reminded him of the plump, fleshy log that swung between Martha's legs.
Every second seemed to be an eternity to Adam. At long last, Katie and Martha announced that they were about to leave. The two of them gave a round of farewells as they headed towards the house.
"Adam," Martha said. "Before we go, could you show Katie to the nearest bathroom?"
"Yeah, maybe the one upstairs?" Katie said with a mischievous smile.
"S-sure," Adam said.
The trio walked upstairs as casually as possible. Adam knew that the two women weren't looking for the bathroom, but Adam's bedroom. After they were inside, Adam closed and locked the door.
"It's about time," he heard Katie say behind him.
As soon as he turned around, Katie pinned him to the door and pressed her mouth against his. Adam felt her tongue sliding past his lips, and met it with his own tongue. The two horny teenagers let their hands rove all over each other's bodies as they indulged their passions.
"Ohhh," Adam moaned as Katie kissed his neck and ears. "You don't know how much I wanted you. I thought that I was going to go crazy down there."
He felt a pair of hands fidgeting with the button on his shorts. Looking down, he saw Martha on her knees, unclasping his pants and pulling them down. She was breathing heavily and had a hungry look in her eyes.
"We don't have much time," Martha said as she grabbed his dick. "Oh, my god! You're already so hard!"
Adam's breathing grew more labored as she took his erect dick into her grasp and began stroking him. Adam moaned loudly, already feeling as he was about to blow.
"Shhh," Katie urged him as she caressed his face. "You need to keep it down, this is only a quickie."
Before he could respond, he gasped as he felt his dick enter Martha's hot mouth. She hummed with delight as she savored the taste of his flesh. Adam gasped with delight as he felt her fingers enclose around his balls, gently massaging them as she sucked on him. Unfortunately, due to already being super-horny from interacting with the ladies downstairs, so he didn't last very long. Katie tried her best to keep Adam quiet, pressing her mouth against his as he blasted his cum into Martha's mouth.
"Mmmm," Martha said after taking him out of her mouth and gulping down his load. "Thank you so much, honey. That should keep the both of us satisfied for the next few weeks."
"What's that mean?" Adam asked. He looked over at Katie, who was looking at him with a concerned expression. He knew that something unpleasant was going to happen.
"I have it on good authority that your finals are approaching," Martha said. "I don't want the two of you getting distracted from your studies, so, I won't be having sex with either of you."
"What?!? Why?"
"Like I said," Martha said as she got to her feet. "I don't want to distract you from your studies, whether you pass or fail your classes will not be up to me, but the two of you."
Adam felt like arguing, but he knew that it would be useless; they all knew that it was right.
"Sooo," Adam said. "After we pass our classes..."
Martha smiled and put each hand on the chest of both her daughter and her daughter's boyfriend. "Then, I'll make sure that the two of you are well-rewarded for your hard work. Let that be a motivator for the two of you."
The next few weeks saw both Katie and Adam studying furiously for their exams. Adam was already a good student to begin with, so he felt confident that he would pass his classes without incident. He even helped Katie with her studying, and when she felt that she had grasped the materials well enough for one subject, the two of them would relieve their studying tensions the best way they knew how.
On the weekend before finals week, the two of them were in Adam's bed, late Saturday afternoon. Katie lie on her side with leg up in the air, panting and squealing, while Adam lie behind her, driving his rigid cock into her as he held up her leg. Thanks to months of working at the nursery, and amazing sex, his formerly wimpy body was gaining tone and definition. Katie, being almost five months pregnant, was finally starting to show the slightest bump in her belly. For now, Adam wasn't concerned about her baby bump, but only thought of pumping his girlfriend full of his tensions.
