Chapter 7: Opening Pandora’s Box
Erotica Sex Story: Chapter 7: Opening Pandora’s Box - This is the story of how helping my daughter, Katie, keep her vow to remain chaste until marriage led me to violate my own sacred marriage vows. One decision led to another as I descended, bit by bit and drop by drop, from being a moral and faithful wife to committing adultery by fucking Katie's 17 year-old boyfriend in our marital bed – all right in front of Katie.

At that point I knew where all of this would end. Suffice it to say that after that day I was nude daily while Brad and Katie kissed. We repeated the events of the prior day, me holding Brad’s cock and Brad fingering and licking me. Clearly Brad was spending more time with his lips between my legs than in kissing my daughter, his actual girlfriend.
But it didn’t take long before Brad wasn’t content in just fingering and licking me. He continued to try to push the limits further and further. He started jerking himself off while he fingered and ate me, and he would aim his cum at my exposed pussy while Katie stood over him, watching.
In my libertine days, I had permitted boys to rub their cockhead on my clit, and Brad eventually reached that point as well. My legs were splayed open, he stood over me, and he masturbated himself on my clit as Katie watched. I was on regular birth control pills, so I wasn’t concerned about Brad’s cum flooding down from my clit into me.
The final inevitable step was the day that Brad’s cock slipped into my pussy. First, just his cockhead slid over my opening. But when he found no resistance from me, on the next pass over my pussy he pushed in and entered me. I was just too far gone at that point to force him to pull out, and I have to confess part of me didn’t want him to pull out. I wrapped my legs over Brad’s back and pulled him into me. I even let him come inside me. My final descent into adultery was complete.
I didn’t know whether Brad’s friends fucked their girlfriends – he never claimed that they did. But Brad definitely got to fuck his girlfriend’s Mom in her place. There was no going back after that. We moved the three-way relationship upstairs to my bedroom, where each afternoon after school I was fucked in the marital bed I was supposed to share only with my husband. Brad and I were always nude and Katie was always dressed, sitting on the edge of the bed, demurely watching.
When Ben came home after work, he typically found me in the kitchen making dinner for the family, but standing with a pussy filled with Brad’s cum leaking into a panty liner. Later in the evening, on those occasions when Ben and I made love, my pussy was already wet and ready, lubricated with Brad’s cum. But he never had a clue.
Epilogue
Katie and Brad dated for the rest of high school and went to the local college together. They seemed to everyone to be the average well-behaved teen couple, holding hands at the movies and never going further than a light kiss now and then. Katie was happy and Brad was sexually satisfied; why wouldn’t he be – he had me! Meanwhile, Katie got what might be considered an advanced college level course in libertine sex – or at least she “audited” the course and never had to take the exam to show what she learned.
After graduation, Katie and Brad got married and Katie finally shed her chastity vow. On her wedding day, as I was helping her get dressed, she turned to kiss and hug me:
