Karyn opened the door and, shocked by what she saw, screamed, "What are you doing, Jon? She's your mother!"
Jon had an orgasm, shot his seed into his mother's eagerly awaiting pussy, withdrew and said to Karyn, "But I love her! Why should I hide my love just because society says incest is wrong?" Jon and his mother cuddled, unashamed by both their nudity and their incestuous act.
Surprisingly, Karyn started crying. "I thought I was the only one," she sobbed.
"What do you mean?" asked Jon.
"My mother and I have been lovers for years," replied Karyn. "I've just been too ashamed to admit it because society says incest is wrong. I was also afraid to admit it to you because then you might find out how we felt about you and your family. We're as much in love with you as we are with each other, but I didn't say anything because I was afraid you would reject my love because of my incest with my mom."
"I was afraid you would say the same thing to me," said Jon. He got up, hugged Karyn and began to undress her. "Looks like we're going to have to make up for lost time then, won't we?"
A few hours of intense lovemaking later, Karyn and Jon's mother snuggled in Jon's arms, their heads pillowed on Jon's naked chest. Jon's mother said to Karyn, "I've been wanting to get you and your mother's panties off for years now. Guess now I can finally make our little threesome a foursome. Isn't that right, sweety." Jon grinned as he felt his cock getting stiff again. Karyn and Jon's mother giggled as they competed to give his member a friendly squeeze.
