Nick wiped the last of the cum and pussy juice off his face, staring past his mother's sopping wet hole into his father's intense gaze. He was scared out of his mind. But he felt oddly brave, too, as though getting laid in such a dirty manner had resolved something for him. What that was, he still had no idea.
He shifted his weight, feeling really uncomfortable. What a nightmare, being caught by his father having sex with his mom! But Nick had somehow managed to get away with it again, just like when he was punished for stealing his mother's sex toys. He couldn't believe his luck.
"Ah, Mom, Dad? Is it ok if I go to school now?" Nick asked, picking up his clothing and trying to cover himself. "It's probably about lunch time. If I leave now, I can get to 5th and 6th period."
"I'll give the school a note tomorrow saying that you had a sudden case of the flu," Susan said, causally stroking her pussy. "If you were seen leaving the house now, it might cause some unwanted rumors. And I'm sure missing one day of school isn't going to hurt a man of your caliber."
"Mom, it's Elisabeth who's the genius, not me," Nick exclaimed.
"You don't give yourself enough credit," his mother laughed, pushing her breast up so that she could flick her tongue against her nipple. "Besides, it seems you could get quite an education right here."
"I don't think I understand you," Nick replied nervously. He didn't like where this was going one bit.
"Please!" his mother replied, spreading her legs in front of him. "You could stand to learn a lot more about sex. You have a nice, healthy eagerness, and with a little stamina, you might make a really good lover. But you really lack a lot of know-how. And so, I intend to give you a special lesson. Why don't you take your father's place in the chair for a while, and I'll use him to show you exactly what I mean."
Nick gasped. It was really too much for him. He didn't want to watch his parents have sex. No son would what that! Eew! That was just wrong. It was dirty. He couldn't take it. But he immediately realized that he was somehow drawn to the prospect.
His mom was really hot, and seeing a cock in her would be great. Besides, being dirty could be fun. Nick would have to do a lot of naughty stuff when he started doing sex magick with Elisabeth and Amber, so he ought to get used to the idea. How else was he ever going to learn to be a real man for his little sister?
"Ok, Mom, teach me," Nick said, throwing his clothing onto the floor and taking the chair next the bed. His father quickly shed his clothing and got on the bed next to his mother.
Nick was surprised to see that his father had an erection that was every bit as big as his own. Nick had never really seen an erect cock before, and was convinced that his own nine-inch member was insanely big.
Susan touched Samuel's cock lovingly, as though performing a well-loved rite that she hadn't been able to conduct for years. Samuel grunted, and Nick whimpered in pleasure. It wasn't hard to pretend that it was his own cock she was fondling.
"You've probably noticed, with your little experiments in masturbation, that the head of the cock is the most sensitive part on a man. There's a little nerve cluster here" - she gave her husband's cock a little nibble, causing him to groan - "that really gets a guy worked up. But that doesn't mean that you ought to focus entirely on pleasuring the head. The testicles and the nipples are often very erogenous, especially when a man is really aroused."
Nick didn't ever expect to have to pleasure a man. He was only interested in women, but still, his mom telling him about a man's body turned him on. He imagined his mom's mouth sucking on his balls, her teeth nibbling at his nipples. Imagining her touch on his nerve cluster made his cock begin to swell. He couldn't help it. His mom talking about this was so damn hot.
"Now you know that the clit is very sensitive on a woman," Susan said, spreading herself apart to give her son another glimpse of her absolutely fabulous pussy and tickling her clit playfully. "You also didn't have much trouble finding my G-spot. I suppose you know about the G-spot from erotic stories and porn?"
Nick nodded so his mother continued.
"But the same principle applies to women as to men. Other regions of my body should be stimulated for optimum results. You could have increased my orgasms tenfold if you paid a little extra attention to my other sensitive regions."
"Oh," Nick said, feeling a little deflated. He had thought he had given his mother the fuck of a life time.
"Don't get me wrong, you were a great fuck," Susan replied when she saw her son's downcast face. "You made up with earnestness what you didn't have in knowledge. I'm just trying to be a good mom and give you a little sex ed. Besides," she added, rubbing little circles around her prominent clit. "I know it makes you horny to hear me talk about it."
Nick moaned his agreement. He liked that his mother wanted to pleasure him with her words.
"I'll use your father to give you a blow by blow account of everything you did right and wrong. You might see something that you didn't catch, and it would be really kinky having you here to watch."
Nick was so horny now that he really wanted to stay and watch. Who was he to turn down free porn, even if it was his parents? It felt really weird, but who was he to be picky? He'd just fucked his mom, and that beautiful cunt of hers was so damn appealing. Now that he had given in to his darker desires, no amount of moralizing could stop him. He was invincibly dirty now, and loving it.
Nick watched in suspense as his mother laid herself back down on the pillow, like she had before he had entered her, and his father began to climb on top, supporting his weight on his elbows just as his son had done only minutes before.
It was so wrong, so absolutely evil, but Nick couldn't take his eyes off of the sight before him. Every moment, every sensation drew him in and made him shiver with desire. He wanted to climb on top of his mother again and thrust his cock into her. He wanted it to be his cock that pounded away inside of her, not his father's. By what right did such a cad possess such a beautiful woman? And why did he have to come home now, right when his mother was most vulnerable to his desires?
Nick shivered, his hand savagely pumping his cock. His mother pounced on his father so he toppled back, his member still buried deep inside of her while she straddled him, forcing herself up and down on him.
Nick heard tapping on the glass outside and looked to see Elisabeth and Amber standing out in the back yard. Elisabeth motioned for him to step outside, and Nick reluctantly began to put on his clothing.
His mother was fucking his father like a wild woman, but she looked up when Nick moved.
"Uh, there's something I need to take care of outside, Mom. If I'm not back soon, can we continue this another time?"
Susan laughed and continued bouncing up and down on her husband's cock.
"Any time you like," she said with a little wink. Nick got up and left the room.
What was Elisabeth doing outside, he wondered absently.
The moment he closed the sliding door behind him, his sister pulled him by the arm into the bushes by the swimming pool where Amber was waiting, fidgeting absently with the dildo that filled her pussy underneath her pleated skirt.
"Where have you been?" Elisabeth exclaimed. "Amber and I went to check on you at lunch to make sure you were still wearing your butt plug, and your teacher said you never showed up. So we got worried and cut class to see what happened. Mom didn't find out about the sex toys already, did she?"
