From Sister in Law to Slutty Wife (MFF Fiction)

I submitted this story before under my old user name. Please enjoy and send me any comments you may have. This is unfortunately fiction.

“Off to work,” I chuckled to my wife as she pulled away from the garage.
“Yeah, yeah you jerk.” she replied. I waved at her as she backed out and then closed the door. I had already set up my computer on the work desk. Sure the pandemic might have destroyed all of last year but at least my position changed to permanently work from home. I guess not bored employees are productive employees.
“Hi Johnny,” I heard behind me.
“Oh hey! Good morning. Heading to work?” I responded to Yvonne, my sister in law.
“Not today, I called out. Mental health day, I want to just take a day to myself. I’m still not over everything that happened. Maybe today will help.”
She moved in about 4 months ago after her relationship with her fiance ended badly. Without anywhere to go we offered our extra room for her to crash until she was ready. Which would take extra long since her ex fiance was in upper management at her job so she quit. So is life. The first few weeks she was a sad mess but lately she seemed to be doing well. Well since the incident.
Yvonne had an attitude but our personalities complemented each other. To be honest, I got along more with her than my wife sometimes. She was a bit heavy set but had a thick hourglass figure, short, wavy, auburn hair. She loved to do her make-up and was always glammed up well except for the few weeks after the break up.
“Well, time to take a shower. Then I’ll cook some eggs and bacon for us,” She said with a smile.
“Thanks! That sounds delicious,” Her new job did not pay as well as her old one so she volunteered to help around the house to make up rent.
I turned back to my computer. I could not concentrate. Seeing her triggered that memory. The incident.
It all happened about a month ago. Working from home has its advantages like surfing the net on stuff you’re not allowed to look at during work. Well this day was one of those days. It was a slow day at work. So I began to surf some porn on my phone. Once I found something that titillated the senses. I took my member out. It grew as I started to play with it. I was about to start the finishing touches when I felt a weird presence. It was Yvonne! She had not gone to work and had come out of the room. She stood there with her mouth opened. I quickly tried to put it away but being as stiff as I was I was doing a poor job of it.
“Sorry,” is all I blurted out as I struggled to put it away.
“Me too, sorry,” she said as she snapped out of it, “don’t worry I didn’t see anything.” She lied.
She hurriedly took off to the garage. How could I forget that today was her late day. That embarrassing moment brought something good though. Her demeanor changed overnight. She was less sulky and more open and happy. Did my 6 inch uncircumcised Latino cock cause that? Maybe, maybe not. That night I had one of the best sex sessions with my wife. I thought of her sister as I came in her. I was feeling guilty afterwards. I shouldn’t have done that. I love my wife.
Today at work. It was a super slow day. As I was working I heard Yvonne get out of the shower and go into her room. “Time to make breakfast,” she mentioned as she passed me. I was almost done with everything on my “to do” list. I sent an email to my work group telling them I was logging off early.
I closed my computer and left for the kitchen.
“Taking a break?” my sister in law asked.
“Nah, called out. I finished with everything on the docket.” I responded.
She gave out an approving nod and, “Aaahh”.
She had done her makeup, I noticed that she had put on a nice orange lipstick. It looked good on her. She was wearing a loose blouse that showed off her cleavage. I wondered if her big breasts were augmented by a good bra. Her black yoga pants showed off her bubble butt. I love yoga pants.
“You’re all dolled up today.” I told her as we were eating.
“Hey, you only live once and I think if you look good, you feel good. Some self soothing. I can have a crappy day but at least I’ll look good having it” She grinned as she said it.
After breakfast however I could see her demeanor changed. She stopped smiling and looked depressed. I asked her what was wrong. She said nothing at first.
“C’mon you can tell me.” I assured her.
“I had happiness in my hand but it all left one day. I was going to get married,start a family, but then HE had to throw it away by going back to his vices.”
“Hey,” I started, “it’s better that it happened now rather than when you were married,”
“I guess,” I stood up to give her a hug. She was holding in tears but we hugged. “Thank you for what you and Kate (my wife) have done for me. I appreciate it so much!”
She squeezed me tighter. I felt her breasts press on to me. I started to rub her back. I felt a sensation in my crotch. “This is a very inappropriate time for this.” I thought as she pressed herself harder to me, “Thank you” she whispered as she took her head off my shoulder to look at me.
Her blush was a bit smeared but she looked at me with a sheepish smile. She had to feel my cock pushing against her. She smelled good. I wanted her. Her eyes triggered something in me. We both leaned forward to each other and exchanged a single kiss, then another, then another until I made the move and passionately started kissing her. She did not pull away, on the contrary. She kissed back. Our tongues eagerly explored each other’s mouths.
“What did we just do?” She exclaimed. Her chest heavily panting up and down.
“I know, we shouldn’t have done it.” I said, “but part of me feels that it was right.”
“Same here,” She looked at me. Her longing stare telling me that she wanted more, everything, “please if just for today. Let me show you how much I want to thank you.” She slipped her hand under my shorts. Finding what she was looking for she gently scratched my balls with her manicured nails. She then ran one of her fingers along my shaft stopping at my slit and gently scratching it.
“There was only one person that had ever done that to me and she was at work! How did she know..” another kiss broke my train of thought.
“Please,” she said. I kissed her back and led her to my marriage bed. I began to nuzzle, lick, and kiss her neck as I helped her take off her blouse. She undid her bra revealing her heavy breasts. They were nice and tan, hung a bit but were nice and plump. Her areola was a nice brown like my wife’s but they were much larger. I cupped her breasts, kissed them and took them into my mouth. She slowly murmured in pleasure.
“Yes, Johnny, they’re yours. All of me is yours. Use me. Explore me. Treat me as your wife. I’m your personal slut.”
I did not expect her dirty talk but it drove me wild. With that I pawed at her pants and took them off along her panties. Her pussy was visible. I threw her down on the bed and began to feast at her sex. Her pubic hair was trimmed, her pussy was hidden between two thick lips. Unlike my wife whose whole flower showed. I dove in tasting her. I thrusted my tongue into her and lapped up all her juices. My tongue explored and found her clit. I opened her lips for easier access. I started to suck lick the clit under its hood. She squirmed, pushed my head down on her as she wrapped her legs around me. Her moans echoing through the house only for me to hear.
As I finished. I moved to her. Her tongue greeted mine. She was drunk on her taste on my face. I rolled over. She began to lick my nipples. Gently she bit them then kissed my body until she was face to face with my cock. She kissed the tip as if greeting him. Kissed the shaft. I noticed some of her lipstick had rubbed off on it. She began to kiss and lick my balls. She engulfed my member in her breasts. It was away in a dream cloud. They felt so soft. She finally took me into her mouth. All the way. She gagged and gurgled. I love that. She never looked away from my gaze. She came up for air spit dangled from her mouth. She continued until she was satisfied then we made out. I tasted myself on her. I was just as drunk on our love as she was. I took my cock and pushed it inside while she was on top of me.
“Aaaay, si damelo.” she said in Spanish, “put it all the way inside.” I did as she commanded. She bounced on my cock. Screaming in pleasure.
“Thank you!Thank you! Thank you!” She said as she rode. I was at my limit. She felt it too. She stopped.
“Not yet, baby.” I want another position. She got on all fours facing our open bathroom mirror. “I want to see us at our climax” We kissed and I started to fuck her doggy style. I saw us in the mirror. She was looking at me. Her mouth opened in ecstasy. Her breasts swung heavily. I wanted Kate below her, pleasuring Yvonne while I fucked them.
“Yes baby, make me yours Make me your bitch! Mark me as forever yours!” She screamed while moaning.
I rammed as deep as I could and released everything I had in her.
“Yes baby, give me all of it. Fill me.”
I stayed in her while I grew soft. We kissed and enjoyed this moment. She began to clean me with her mouth. Kate had never done that.
“I promised to clean up when I moved in, remember?!” She exclaimed jokingly. Slowly I became hard again. She began to suck me off. Before it became too much I asked her to put her glasses on.
“You perv,” she joked but put them on. She began to suck me off again. Her tongue found my slitt and began to play with it. My toes curled in joy.
“We taste delicious,” she murmured.
I was close, She took me deep. I told her I was about to cum. She took me out and took my load on her face. Even though I had just came, I covered her face. One of her lenses was covered as was her auburn hair. Cum dripped over her mouth. She took a finger full and tasted it.
“Hmm sweet,” she said.
She moved up and we made out. I tasted myself and her. She was right. That’s when I heard the door open. We both turned around. Standing there was Kate, my wife.
I stammered but was interrupted.
“You couldn’t wait until I got home could you?” Kate said.
Yvonne had a sheepish smile. “No, now I see why you chose to marry him,” She turned to me. “What do you say? Got a few rounds left in you?”
**********************************************************
My cock immediately stiffened. My sister in law sat next to me naked. Her face was covered in my cum. My cum was also starting to leak out of her pussy. My wife was standing at the doorway. She had caught us at the end of the session.
“You couldn’t wait until I got home could you?” Kate, my wife’s words echoed in my head.
Kate was moving towards us. “Espero que tengas mas.” She said to me pointing to my cock.
“Siempre,” I responded.
She began to undress once she was naked atop of the bed. She went up to Yvonne, my sister in law and licked what was remaining of my cum off her. She then guided Yvonne’s face to hers and shared my cum with her. I was ready to have them both. I was in heaven.
While Yvonne was more heavy set Kate was voluptuous. Hourglass figure, big ass, big breasts although not as big as Yvonne for both ass and breasts. She had long straign brown hair, she also wore glasses. She moved her figure down to Yvonne’s pussy and began to eat her out.
“Yes, keep going. I’m both of your slut. I’m just your naughty sister and sister in law.”
Kate looked up, “ No, you’re no longer Johnny’s sister in law. You’re his wife.”
“Yes, big sister, I’m his wife!” She, as my wife brought her to completion, “Thank you for letting me join you,” She turned to me, “I will be a good wife, always loyal, eager, always ready.” With that I kissed her. My wife came to me and we also kissed. I tasted both myself and Yvonne on her. She moved down to my shaft and took it into her mouth. Yvonne joined and pleasured my sack.
“Do you want to know what he also likes?” she took me out of her mouth and began to lick my asshole.
Yvonne took the opportunity to start to suck me off. “He’s naughty,” She murmured. Kate went to my balls. I felt Yvonne starting to tickle my asshole. Her nails felt amazing. Kate whispered something to Yvonne’s ear. She giggled and left. Kate took me and we rolled over to missionary position. I penetrated her wet pussy. I began to pump her when I felt Yvonne starting to lick my ass. I felt some lube being poured as she massaged my asshole.
This drove me wild but Kate wrapped her legs around me preventing me from going faster. That’s when I felt the unmistakable feeling of Kate’s strapon. Yes, my wife pegs me and I love it. No kink shame. I was getting a train ran by Yvonne. I did not last long and felt myself spurting into my wife. Each time Yvonne rammed me it made me spurt a little more. She rammed me all the way as I did the same to Kate. I twisted back and kissed Yvonne before my wife. After we all separated I stood up to allow Kate and Yvonne to get closer to each other. I had payback on my mind. Hopefully I could pull it off.
The show my wives were giving me put me back at attention. Yvonne had pinned Kate on the bed. She was on all fours kissing Kate. I moved back and began to kiss Yvonne’s asshole. Kate got the jist and freed her legs to hold her in place. I lubed her and myself and began to stretch her out before penetrating her asshole.
“Please,” she pleaded. “I’ve never done that. Please be gentle.”
“It really is our wedding night. Johnny you’re about to break my sister’s anal cherry.” Kate said
I inserted myself into her. Yvonne let out a yelp of both pain and delight. She began to gyrate her ass as I started to pump her.
“Ay, ay, ay, si,si, si” She said I started to apply more force. I looked at her on the bathroom mirror. She was enjoying it. My wife was playing with her big tits as they swung. I started to caress her pussy with one hand. Her head instantly perked up and asked for more, harder, break me! She was sex drrunk. I felt my Kate’s hand playing with herself. Looking at her expression she was almost done as well. I came inside Yvonness asshole. It was not as much as before but it was plenty. I felt warm wetness at my knees. My wife was squirting.
I got to my tummy and began to lap Kate’s juices as I ate her out. Yvonne helped me but I heard her gasp. Kate was eating her asshole collecting my cum as it oozed out. When finished she shared my cum with both of us.
My sister in law had become my other slutty wife.
