Caught Having Sex by my MIL.

We woke up one morning, and I started rubbing my wife's thick ass. It was light out already, but we're upstairs by ourselves, so we don't shut the door all the way because kids are on the bottom floor of 3. I noticed a couple of minutes in that my wife was already really wet.  I love eating her pussy, so I adjusted myself so I can start licking her ass from behind.  I spread her checks and lightly lick around her asshole and make my way to her soaking lips. She only cums from clit play, so I like to tease her a bit before fully licking her clit. As my tongue gets to her clit, she is slightly humping my face and breathing heavily.  I continue licking and feel her hand reach back and grab my throbbing hard cock. I already had pre cum dripping off of it. She then says,  "Mmmm, I can tell you are enjoying yourself." 

It didn't take long this morning and my wife stops jerking my cock and starts breathing heavily.  I know she is close so I keep licking even though my jaw is getting sore. As she gets to her orgasm, she starts moaning louder then normal. I'm so turned on I don't stop. Her body arches and she lets out a deep breath and loud moan,  cumming into my mouth.  I continue licking until her body can't take it anymore.  She comes back down and says to me, "That was so good baby, now it is your turn,  I'm going to rock your world." She not much of a freak in bed, so this turned me on. 

She sits up and pushes me back onto the bed.  She then positions herself by my cock.  Her ass and pussy facing me, like 69, but not on me.  I can see her sucking and jerking my cock and I can still rub her kitty.  I can feel she is still soaking wet which is turning me on even more.  The cabin is all wood,  so most of the time you can hear people walking around in the living room from our room.  It was sorta quiet, which was weird at this time of day,  but I was enjoying my wife sucking my cock, so I didn't give it much thought.  Our bed faced forward,  but you can see out into the lift in our hallway that leads to our bathroom.  I must have closed my eyes while she was sucking my cock because at some point,  my wife took my cock all the way down into her throat.  I opened my eyes, and let out a deep breath in pleasure. In that moment I noticed,  what looked like a shadow outside our door.  But the kids would have been loud coming up the staircase, and her mom,  being a SSBBW usually doesn't come up-stairs.  As my wife is sucking my cock and stroking it in front of her face I see now that her mom is outside out door. I actually see her looking in. I must admit, it was a huge turn on, seeing my mother in law, outside the door, watching her daughter sucking my cock.  I start to play with my wife clit again. And it didn't take her long to come again, she was breathing heavily immediately and by her dry humping motion I could tell orgasm two was on its way. 

I look towards the door and can see her mom hasn't moved an inch. I keep rubbing my wife's clit as she is now moaning more loudly,  I am also getting close to coming with everything that is happening. I decide to say out loud, I'm close baby.  She moans, "Me too",  and then her body starts shaking again as she comes from my fingering. Just as she starts to come, her mouth closes tightly around my cock and I release my first load into her mouth. She isn't into swallowing, so she took her mouth off my cock for the next couple of loads and managed to squeeze it in between her huge tits. I was able to see her mom, standing there just staring, but now has a smile on her face. 

My orgasm was one of the best I'd ever had. I know it was mainly because I just watched my MIL, watch her daughter come and suck my cock. As we got up to clean, mom walked away. We showered and went downstairs. Mom was in the couch, we say good morning. She then says, "The toilet on my floor wasn't working, so I needed to use yours".  My wife had me check her toilet, the chain had simply come off. I fixed it, turned and stepped barefoot on something on the floor. I look and it was my MIL's panties. I pick them up and find the crotch is soaking wet and gooey. These must have been the ones she was wearing as she watched from the doorway. I must admit, I did have a lick of her juices. It immediately made me hard again. I then took out my now throbbing cock and slide it through her goo. It felt so good. I wanted so badly to go shower again and jerk off to this experience, but I heard my son running up the stairs to find me, so I quickly put my cock away and threw the panties to the side.  

Later that evening, the kids were in bed downstairs and my wife and I were having cocktails. Her  mom asked for one. I made her one and her daughter asked what made her want one tonight. She smiles and says, "It was just a a really stressful morning". My wife asked if it was bad stress,  and she said "No, just eventful" She also said she saw some really neat animals this morning. I giggled to myself in the kitchen, thinking we were the animals. Not sure if she fingered herself from what she saw, but later that night. I took a shower before bed and shot a load thinking about her watching and the taste of her pussy juices in her panties.
