It was midway through my daughter Cathy's senior year of high school. I was cleaning up the kitchen after dinner, and Cathy was in her room with Kent, her boyfriend, studying. A typical suburban scene.
After wiping down the counters, I went upstairs to Cathy's room. I know that Cathy and Kent fool around a bit, and being the conscientious mother I am, I knocked on the door. I certainly wouldn't want to embarrass my daughter by walking in on any hanky-panky!
I listened for any sounds of them jumping off the bed, rushing to put clothes back on, or anything like that, but all I heard was Cathy saying "Come in."
I walked in and sure enough, they were really studying, Cathy on the bed and Kent at her desk. "Hi kids, I just wanted to know if you needed anything before I turn in."
"No thanks," said Cathy, echoed by Kent's "No ma'am."
"I just have a couple more chores to do, and then I'm going to bed," I said. "Don't stay up too late!" I turned towards the door, but turned back. "Actually, I just had a thought! Kent, could you help me get something off the top shelf in the garage?"
"Mom, we're studying!" said Cathy.
"Selfish bitch!" is what I thought, but I said "This will only take about ten minutes, honey. Just to get a can of paint down so I can write down what kind it is, then to put it back up."
"Sure, Mrs. Anderson," said Kent, jumping up. "I don't mind."
Kent followed me down to the garage. I held the door for him, then closed and locked it. I heard his zipper, and then his belt buckle hit the garage floor. I bent over the car and pulled my slacks and panties down. My hands were shaking. I felt Kent's huge cock poking at me, trying to find my slit. I reached between my legs and grabbed it. Kent was rock hard. My hand barely fit around it. It was one of the biggest cocks I had ever had, and I have had a lot of big cocks.
I guided the head to my hot canal. I had been wet ever since Kent had come by to visit my daughter. He pushed it in, so far in! It was so good, I would have screamed, but Cathy was right upstairs, so I whimpered and grunted while Kent drove his huge monster in and out of me. He pumped without stopping for about five minutes, and then arched his back as he shot spurt after spurt of hot come deep inside me.
If Kent had one flaw, it was that he was too quick to come. The first round, anyway! There were advantages and disadvantages to sleeping with an 18 year old, but the fact that he could usually do it two or three times in a row, with a little encouragement, was a big plus.
Of course, it was also a little problem that Kent was dating my daughter, but I could definitely see the advantages in that, too. First of all, Kent's dick was too big for Cathy, and the poor girl couldn't even give him a blow job. A dick like that wouldn't go underused for long, and I liked to think that I was even doing Cathy a favor. If it wasn't for me, Kent would soon have gone off to greener pastures. As it was, all three of us got what we wanted. Kent got sex as often as we could get a little privacy, I got the huge cock I liked, and Cathy got to keep her boyfriend, none the wiser. Or so I thought.
Kent and I straightened ourselves out a bit in the hall mirror, and then went back upstairs. As Kent opened the door to Cathy's room, I called out to the kids "Good night, you two! Don't stay up too late! Thanks again, Kent," I added.
"No problem, Mrs. Anderson," said Kent. I shut the door a little quickly, as I just that moment felt a big glob of Kent's semen ooze out of me. It would have stained my slacks if I had given it a chance! I hurried to my room, peeled off my clothes, and jumped into the shower. I was wearing red lacy panties, and they were absolutely full of Kent's come. "It's a good thing Cathy never does the laundry," I thought to myself, as I soaped up.
I did my best to make Kent forget he was fucking a gal old enough to be his mom. Big boobs and a deep throat went a long way to help him forget, but I tried to wear sexy underwear and stay clean shaven for him. Not that he noticed much this time!
It was a few days later that my problems started. Cathy began to mope around the house. She became more and pouty and unhappy. Even worse, Kent wasn't coming around. I began to worry. What if they had broken up?
I confronted Cathy. "Honey, tell mommy what's going on." It took a while for me to get anything out of her, but it finally came out, with tears and sobs. Apparently. that last night Kent stayed over, Kent and Cathy had fooled around. Kent's cock was too big for Cathy to get it in her mouth, but it seems that Cathy licked it, and tasted something on it she didn't recognize. It took her a few days to realize that what she had tasted was pussy.
Cathy held me and cried. "Honest, mom, when I realized that I had been licking some fucking bitch's pussy juice off Kent's cock, I almost threw up."
""How would you have felt if you knew you had been licking your own mother's pussy juice," I thought to myself. If she and Kent had started fooling around a few minutes earlier, that pussy juice would still have been wet. That was so wrong. "Poor baby!" I said. "But are you actually sure that is what it was? Maybe he was working out, and the sweat..."
"No, that's what I thought at first, but the more I thought about it, the more sure I was. I can't believe that stuff came out of some gross snatch and there I was, licking it up like a stupid puppy."
"Shh," I said, as I smoothed her hair. "What did Kent say about it?
"I haven't spoken to him about it. I don't ever want to see him again. I'm sure he knows why."
I used all my powers of persuasion to convince Cathy to get back together with Kent, to not tell him what she had discovered, and to act as if nothing had happened. "You told me that Kent has a really big dick, and you two were unable to have vaginal intercourse. You can't expect an 18 year old guy to go without forever. The good news is that Kent really loves you. He wants to be with you, even without the sex! You can't blame him for slipping up once, sleeping with some girl he doesn't love just for relief!"
"But mom, I get him off with my hand all the time!"
"Oh honey, that's not good enough for a man. You know he has to have the real thing. I think it was good that he met someone who could deal with his size."
"Yeah, probably some fucking slut with a huge gaping pussy. Do you think he came on to her, or she came on to him?"
"I can't really imagine Kent ever looking twice at a girl besides you. She might have... talked him into it."
"Yeah, 'talked him into it.' She probably heard he had a big dick and threw herself at him. She was probably so wet that he could smell her dirty hole, and it was hard to resist. Do you think she just grabbed his dick through his pants and started rubbing it? Fucking horny slut."
Actually, some of this was uncomfortably close to the truth. I wanted to defend myself, but I couldn't really. "Well, she might have been lonely."
"Lonely my ass. She's probably one of those girls in the back rooms at the frat houses, spreading her legs for any moron with a dick. Or one of those girls who gets drunk in a bar and sucks off five guys in the bathroom. I bet she has big boobs that she shakes at the boys to try to get them to stick their cocks in her. Fucking loose slut!"
This got me a little angry. I was certainly not a loose slut like that, although I had normal desires. I could have been one of those women sucking cock in the bathroom, but I wasn't, for who? For Cathy! For her sake I had to be respectable, so at least she shouldn't begrudge me her boyfriend's cock once in a while, especially since she was hardly using it.
Still, being a mother means not always saying what you want, so I had to go along with Cathy. "Sure, honey, some back room slut that all the boys have had. Kent would never date her in a million years. Some baseball groupie that the whole team probably fucked. He couldn't get out of it. You know how boys are."
I have to admit I was making myself a little horny. Imagine a whole baseball team of boys with cocks like Kent's! But Cathy was comforted. We cuddled a bit, and I suggested that she not even say anything to Kent. She agreed, and went to bed.
Things went back to normal after that, with Kent and I being even more careful not to be discovered. Because of that, we were fucking less than we had been, which is probably partly why we got into trouble at the party.
