My BIL and SIL: So my wife's brother is married to this girl, we will call her Megan. They each had kids from previous relationships and then had one more together for a total of 5 young kids. My BIL works third shift and picks up a ton of overtime, so he is never home at night.
My wife and I: We are complete opposites as far as our sleep schedule, she goes to bed around 8pm every night and I'm usually up until about 2am. I get one night a week that I go out to trivia at a local restaurant, and my wife is always asleep when I get home.
My SIL and I: My SIL talked to me a few months ago about how they hadn't slept in the same bed for 5 months, and had a dead bedroom life ever since the birth of their youngest. We are also both 420 friendly, so after trivia I have been stopping by their house and we usually sit on their back porch and smoke and chat for awhile.
So Megan is my SIL in the fact that she is married to my wife's brother. Megan is stick thin, has small A cup tits, long black hair and has an ass that I can basically fit in one hand. Every Wednesday I usually go to trivia which ends around 10pm, then I would head over to my SIL place and we would chill, smoke and chitchat until I would finally make my way home. My BIL has worked third shift for the past year, so he is usually at work by the time I stop by, but he knew that I was stopping and hanging out. We are all pretty close, so we have a habit of just walking into each other's houses without knocking.
Well about two months ago trivia got canceled one night, but I didn't want to waste my one night out, so I sent Megan a text on Monday asking if she wanted to hang out on Wednesday and that I could be there earlier than normal. She said sure, that'd be cool and that the kids were usually down by 7 or 8pm.
That night I roll up to my SIL house around 8:15, and most of the lights are turned off except the kitchen and Megan's bedroom, which is just off of the kitchen. I go to the front door and knock lightly, no answer. I try the doorknob and it's unlocked so I figured she must have left the door unlocked for me. I walk into the house and head towards the kitchen. I can hear the TV in Megan's room as I'm coming into the kitchen, so again I just assumed she had left the door unlocked and didn't hear me knock because of the TV.
I round the corner and walk into the main kitchen area, and the door to Megan's bedroom is wide open. Megan is on the bed, head titled backwards and her eyes staring directly at the TV. She had a sports bra on, but wasn't wearing pants. Her legs were spread wide open, and she was going to town rubbing her fingers on her clit. By the time I realized what I was seeing, she noticed I was there, snapped her legs together and was standing up.
The first thing out of my mouth was "Oh shit, sorry!" And I speed walk out to the back porch. I'm sitting there, still picturing Megan's wet pussy, with her fingers stroking her clit, and I realize just how hard I am. I did my best up adjust and hide my erection until Megan came outside. I apologized over and over, she said no it was her fault, she forgot I was coming and sometimes she needs some mommy time to watch a little porn and get off. I said nothing wrong with that, and we decided to still hang out.
We smoked, drank and talked for a couple hours until in my inebriated state, I got bold enough to ask her what she had been watching. She said it was just some random threesome video, but I was feeling a little more bold so I continued the line of questioning. What do you like to watch? Does BIL know you watch porn? Do you ever use toys?
It was that last question that I think made her realized just how much I had seen, and the topic of conversation had started to get me aroused again. She noticed. That was when she asked what porn I like to watch, and I told her that it would be easier to just show her. I was half joking, but I was also high and hard as a rock. That's when she said OK, come show me" and started walking into the house.
