Exhibitionist & Voyeur

When your dad married my mom last year, you didn’t really know me too well. I’m two years younger than you, only just now turning 18, and a year behind you in school. Of course, I knew you. In fact, you’d already inspired many a restless night before you ever moved in across the hall. Now I was sharing a bathroom with my crush? I don’t think I made through l...

Exhibitionist & Voyeur

I could write a story about step siblings banging. Or about a pool boy and the MILF down the block. I could write about a business man’s affair, or about parallel play on a park bench, at night, on some abandoned golf course somewhere. Or maybe you’d like a story about a cheating wife, caught, pleading for forgiveness? On her knees, begging to show her husba...

Erotic Couplings

It was a common situation: their parents married making them step-siblings, and the world as they knew it ended. It was less about them not liking each other than the fact that each resented the other for the intrusion into their lives.

Submitting with Step-sister

by JerkGently on Apr 22, 2025

You watched in abject horror as Jenny dropped to her knees. Your step-sister. Your second heart. Your eternal rescuer. She knelt down before this ugly, old stranger and brought her hands up to rest against the front of his jeans. He was grinning down at her manically… the look of a starved wolf that cannot believe its own luck. Yet she was smiling back up at...

Mature

To be sure, it didn't end there for either couple. In fact, both pairs enjoyed a robust evening of lovemaking. What would have probably been frightening to the two twosomes if each knew this about the other was that not only did their sex sessions begin similarly with masturbatory action, but they also ended almost exactly the same with the women wanting a s...

"No, just thought you'd still be sleeping and...
