Step daughter gets caught and watched and step dad joins in

This is a fantasy based on the true story I posted about catching my daughter getting fucked.

This is a fantasy based on my true story of catching my step daughter and her boyfriend fucking.
I had come home from running some errands and saw my step daughter Monica's boyfriend Cody's car in the driveway. My wife was out of town at a conference for work and it was just me and Monica for a week.
My step daughter at 18 is what you'd call short and stacked. Thanks to playing sports regularly in school she was in very good shape. She is 4'-10" and barely 100 lbs. She had double Ds and keeps her pussy shaved smooth.
I went inside and put my purchases away and headed towards my bedroom to change into my trunks to go have a dip in the pool. After I changed I started out of my bedroom and heard a noise. It sounded a lot like and moan and thought 'those sneaky Lil shits are fucking after her mom told her not at home.' I quietly crept down the hallway towards her room and found the door hanging halfway open. The shade was wide open allowing sunlight to shine into the room and paint a spot light on Monica receiving a hell of a pounding from her boyfriend.
She was on her back and Cody was fucking her deep and hard. The way they were positioned let me see clearly how much of a grip her pussy had on him and I caught sight of cum running down her ass. I watched them for a while before I dropped my trunks and started stroking my rock hard cock.
They continued like that for about 10 minute and I saw his nuts clench right up into his body and he shot a huge load of cum right up inside of her. When he was done pumping her full, he fell off to one side and i could see her smooth shaved pussy bright red, slightly gaping open and leaking copious amounts of cum. After resting a bit she scooted down and started licking their combined juices off his cock before sucking him hard again.
While watching her sucking him off and admiring her cum slimed pussy from behind I noticed he had lifted his head to watch and saw me there watching them go at it. He got a big grin and told her to lay on her back on top of him so could fuck her in the ass and still be able to play with her pussy.
How she didnt see me I dont know but she positioned herself to take him up her ass and layed back on his chest. He then grabbed her eye mask to blindfold her and and cuffed her wrists to the bars of the head board with a set of fuzzy cuffs she usually has hanging there. He lifted her slightly and started a slow rhythm before moving his legs inside of hers to open them wide and show off her freshly fucked teen cunt.
He started playing with her pussy and pulling her pussy lips wide open for me to see inside and then motioned for me to come closer. Against my better judgment I came in up to the foot of the bed while still beating my meat. He mouthed "fuck her" and hooked a finger from each hand into her pussy to pull it wide open. Finally I could take no more so I climbed up on the bed and slid my cock in balls deep in her pusst and started fucking her in rhythm to how he was moving.
Initially she loved the second dick in her and then it must have clicked that there actually was a 2nd dick inside her and panicked a bit.
He told her "monica its ok just relax and enjoy your step dad's cock." I was pretty worried when he called me out and then when she protested a bit he said "weren't you the one saying you wanted to try him out after hearing your mom screaming and moaning a few months ago when they didn'tknow you were home?
At this I started fucking a bit harder and she started saying "I've always wondered how big you are after hearing mom brag to her friends about you a while back. But damn you are thick."
I reached up freed her hands and removed the mask so she could engage as well. She started groping her tits and said "I finally get to know just how you'd feel inside me Chris. I'm glad you and mom found out you're unable to have kids last month because whenever moms not home I want you to fuck me and cum in me."
"Yep that's the only good thing about that particular birth defect. It means I could fuck you so often you'll never be without cum in you and there's no chance of knocking my step daughter up." I replied.
At that the talking stopped and we committed ourselves to giving her the most thorough fucking of her life. We took turns fucking and cumming in both her ass and pussy and ended it all with us both cumming in her mouth.
"It's a good thing im doing laundry tomorrow cause your bedding is a hell of a mess. But that can wait for tomorrow cause I'm gonna add more to it tonight and make sure you cant walk at all in the morning." I told her and asked "so did I meet or exceed your expectations?"
Once she caught her breath she said "oh fuck yes. If I had known you could fuck like that then I'd of jumped you long before now." She laughed.
I told her "you haven't seen anything yet. I just came in part way through. I eat pussy like im starving so next time you'll get a treat."
She looked surprised and said "next time? I thought this would wind up being a one time thing. Don't get me wrong I'd love to fuck you again but isn't it too much of a risk of mom finding out?"
"Then don't tell her. Cause I'm sure as hell not gonna risk ruining what we've just started and my marriage to your mom as well." I replied and added "besides I owe her for cheating on me before we got married. What better way than to keep her sexy daughter pumped full of cum." As I said this I put two of my finger back into her pussy and stirred the mix of all three of our cum and brought my fingers out for her to lick clean.
I stood up and admired the view of her cum soaked form and said "well I was on my way out to the pool so I'm gonna head on out there." I turned back and said "you both are welcome to join me out there."
Cody said he couldn't since he had to leave for work but Monica said "yeah sure just let me put on my bikini first so I won't drip cum clear across the house."
I said "OK but its coming off in the pool so dont get too attached to it."
When she got outside I had to laugh because the bikini she chose was so tiny it didn't stop the cum dripping out of her much at all. I pulled her bikini off and pulled her into the pool with me to scrub the leftover cum off of her and then took ahold of her and pressed her up against one of the jets pussy first to help flush all the cum out of her pussy.
She said "God damn I love how these jets feel on my clit."
I chuckled and said good cause you're gonna like this even more." I grabbed her by her waist and lifted her out and onto the deck beside of the pool. I pushed her back and spread her legs so I could get a taste of her pussy. I sucked her thick pussy lips into my mouth and ran my tongue over her opening making her moan and arch her back. I spread her lips open so I could get at her clit and attacked it with my teeth and tongue while pumping two fingers inside her.
I ate her pussy thru four organs and then made her squirt on her fifth when I sucked her clit into my mouth and sucked as hard as I could on it while rubbing my fingers on her g-spot. It's a good thing we live out in the country because she screamed through her last orgasm. As she laid there panting she motioned for me to join her and slipped back into the pool.
She said "Scoot up to the edge so I can suck your cock. No one had ever made me squirt before so that requires a reward."
I told her "well hun no one has ever been able to get me off with oral before but give it a try. By the way i love that you have an innie pussy, those are my favorite. " She smiled and started in on me.
My god can that girl suck a dick. She had me at the brink in no time at all. Finally she pulled almost all the way out and started swirling her tongue around the head while sucking hard and I told her "OH FUCK BABY GIRL I'M GONNA CUM."
She kept at it and I blew a huge load into her mouth. She swallowed a couple times and then opened up to show she had swallowed it all.
I flopped back on the deck and and she climbed up to stroke him back to full mast again and I said "damn girl you're gonna be the death of me. You just tried to suck out my soul through my dick."
She laughed and said "its not much different than eating pussy and I'm told I'm pretty good at that."
The thought of her eating pussy made me hard again and she climbed up on top of me and lowered herself down onto my cock. Even with how hard Cody and I had fucked her earlier she was still a snug fit. She sat down until my cock head nestled right up against he cervix and said "wow no one has ever been this deep inside me before. My gyno doctor complains about my high cervix is and how hard it is to find but you found it pretty quickly."
I chuckled and said "well this'll likely be the last time I can fuck you without a few hours to rest up for more so you'd better take advantage of my deep seated cock while you can."
She started slowly bouncing on my cock while mixing in some gyrating, twerking and grinding and before long she clamped down on my cock and came hard. I reached down to strum her clit while sucking and nibbling on her nipples and she came an additional 2 more times before I hit my limit and said "I'm gonna cum baby." And she slammed down and ground my dick as deeply into pussy as it could get. I came hard right up against her cervix. We sat there for a while in the after glow and I said "damn I wish I still had the stamina I did twenty years ago because I could go for hours on end back then."
She laughed and we slipped back into the pool for a bit. We played around for while, sneaking little touches here and there and then went inside to rest up for later.
We spent the rest of the time my wife was gone fucking ourselves silly. She had a limp for days on end to the point her friends and coworkers asked what happened. She just said she must have pulled and a muscle or something. She even went put with Cody a couple times already dripping my cum when he picked her up for their date. She wore her miniskirt without panties like usual so my cum was running down the inside of her thighs.
She told me later after her date that Cody found it so hot that he pulled off the road and bent her over the hood of his car to get some of her presumed pussy. She even went out with her little girl friend the same way and the girl loved how she tasted with cum already in her. Since the time we first fucked, she has become a sexy little cum slut I can use whenever I please.
I was nearly a dried up husk by the time her mom came home.
We still have sex when her mom isn't around. She has even mentioned bringing over the girl that bought her how to eat pussy and pleasure a woman but that's a story for another time.
