My wife, Sara, was a virgin when we married, and had naive assumptions about sex and what is permissible. I loved her innocence, yet I did educate her on the basics, then variations, and fetishes. Once over her shock, she became an ardent and flexible lover in every way. Her parents were liberal, but were cautious about exposing her to anything that might harm her innocence. That fell to me.

After our honeymoon, my wife spent a full day with her much more mature childhood friend, Cathy. She glossed over what they did, and hid the best from me for a week. I only accidentally learned the details when we spent a weekend with her parents.

After the first day with them, Sara shocked her parents when their modest daughter walked around their home near naked, in just panties. They adjusted quickly and were happy to wear less around the house in front of both of us. Her mom then dressed as Sara did and spent the day with us in just her panties, while her dad preferred tented boxers, especially when his cock escaped. I adapted and found boxers to wear so I could also flash my cock for them. Though I reset it several times, each time took longer as I enjoyed both parents staring at it. It was a pleasant weekend.

Mother Nancy was still a desirable and sexy woman at fifty with DD tits and a narrow waist. Her dad, Ned, was in good shape for fifty and proud of his thick, seven-inch uncut cock. Mine is about the same size, so Sara wasn’t shocked seeing her dad’s cock, yet something troubled her.

Heading to the hall toilet early Sunday morning, I saw my wife spying on her parents from their ajar bedroom door. Since she was chilled, she wore her threadbare yellow top. It was translucent, except for the worn-out spots made by her hard nipples on her shapely B cup mounds. Something was in her left hand; her right hand rubbed her crotch under her stripped mini panties. I froze and watched her push her panties aside and finger herself just six feet from her barely awake parents.

Unnoticed, I moved closer until I could see her parents naked in bed. We knew they liked to ‘sleep in’ on Sundays. Half asleep, her mom’s tits and one bare leg were out from under the sheets, as were dad’s soft cock and big balls. Sara seemed fascinated since she rarely saw them fully naked. As she began to flush pink, she pushed the door fully open and boldly stepped inside to the foot of their bed. Mom, Nan, stirred, and Sara pulled her damp fingers out of her swollen pussy and licked them as Mom and Dad watched. Where did this boldness come from?

“May I eat you, mom?” she asked in childlike innocence. That was so surprising, given the way she was raised by her liberal parents. I understood both walked around in underwear, mom often topless, when Sara was near — usually naked when she wasn’t.

As she approached her mom, I saw Sara’s exposed and plumped camel toe, and Mom noticed. “What did you say?” Nan pulled the sheets up, over one tit. “We never discussed any kind of family sex. What makes you think to ask that?” Her dad, Ned, stirred, yet left his cock exposed.

“You’re thirty years older than I am, and I wondered what my pussy will look like when I’m your age. My friend, Cathy, took close-ups of mine so I can compare them. She took photos of her parents naked and showed me. She said she ate her mom, then sucked her dad off. Now they are all more relaxed with each other and usually naked. They often have safe, casual sex now. Stu, would you get our phone?”
