Susan's parents

Without waiting for her approval, I quickly selected Ron and Cheryl, Susan's mom and stepdad. I knew something she didn't know. I knew that Susan had had the hots for her mom's husband since they'd gotten married when she was 12. I also knew that I had been fantasizing about my mother-in-law since I'd accidentally sniffed her panties once when Susan and I had started dating.

"My parents, really?" Susan protested.

Before she could say anything else, I rolled over onto her and started kissing her. Susan didn't resist. Instead, she wrapped her arms around me and pulled me tightly against her as she started kissing me back. Ron's cock was starting to get hard as it rubbed against his wife's leg.

"How are you, Punk'in?" I asked, using the nickname Ron had called Susan since she was a little girl.

"You're dirty," she said with a smile. "I like it."

I slid down her body, first to her boobs, where O slowly took turns teasing each of my mother-in-law's nipples. Her breasts were saggy, but big. I had jerked off many times imagining what they looked like naked, and I wasn't disappointed. Susan moaned each time I moved my lips and fingers from one nipple to the other.

"Oh, Ron," she moaned allowed.

I moved further down, kissing my way along Cheryl's stomache until I came to a completely untouched mane of silver pubic hair, which probed my theory that my mother-in-law had been dying her hair for years. That was okay. Maybe even a little hot. I breathed deeply, inhaling her scent.

"Love you, Punk'in," I said, then slid my tongue into her. She smelled and tasted a lot like her daughter.

Susan continued to moan as I ate her, focusing most of my attention on her mother's clit. She started cumming at once as I slid a finger into her. I kept licking her for nearly half an hour, eventually removing my finger so I could slowly drop my tongue lower and lower until I could start at her asshole and lick all the way to her clit in one motion.

As Susan and John, she never let me lick her ass. As Ron and Cheryl, it drove her to another orgasm, this one bigger than the last.
