I am grateful to another Literotica member SylviaG who has helped me with this story.
As I said in Chapter 1, I have plans for my wife Sylvia. The night with Ken and Phil was by way of an experiment. Sylvia passed the test. Over the next few weeks I made sure we chatted about the cards night in bed before we made love. Sylvia seemed happy to do that and it spiced up our lovemaking. I told her I wanted her to make herself available to other men. Because I said it casually with a grin on my face I think she took it to be just sexy talk, a form of foreplay and she kind of played along. Sylvia is the faithful type so I knew it wasn't going to be easy to get her compliance but she'd shown that in spite of herself, her high sex drive makes her vulnerable. I know she loves fucking; it's probably been the cement that's kept us together for so long.
Deep down she knows I'm a swine but even after she's caught me cheating she's been drawn back to me because I can give her what she needs. There's something else too; not sure what you would call it. For example I knew she didn't fancy Phil, he's a bit ugly to be honest. But something about me pushing her to fuck him when he wasn't her type turned her on. Aren't women weird eh?
She's by nature very trusting too. She thinks her sister and I don't get on. The truth is we do and we don't. For a couple of years now I've been saving up in a bank account Sylvia knows nothing about. It's what I've earned mainly from playing online poker and a few things I've sold that I nicked from work. Sylvia thinks I'm looking at porn but I get a real kick out of fleecing those poker players who are "putting their foot in the water" for the first time. I somehow seem able to sniff out the greenhorns and I've got the patience to wait till they join the game before I make my play. Anyway having a bit of capital has given me power over others which I like. This is what happened a couple of weeks ago.
"Where's Sylvia?"
"At work."
"I don't know why she married you; you really are a bastard to her."
"She loves me Julie, now how is my favourite sister in law, ready to pay off the last of your loan?"
"I can't believe I let you talk me into this, god you're an arrogant prick. Where did you get the money anyway?"
"Does it matter? Now take off your dress."
I sit there with a grin on my face as she slips her dress down. She pretends that she does it reluctantly but her eyes betray her. She kneels in front of me and pulls my zip down. She pulls my cock out, and her brief hesitation makes me wonder if she is contemplating attacking it with those long fingernails. I relax when she just jerks it a few times and licks its tip. I've seen her hubby's member so I know mine's longer and thicker. She begins to suck and slurp on it as I feel it grow.
"Good girl, just like Sylvia. Now get on top and remember, this is the last time sexy, so enjoy yourself."
She scowls at me as she lowers her pussy down on my now fully extended prick. I notice her wince a little, but her cunt is so slick and slippery it's obvious she's loving this as much as I am. I like to think that she's creaming herself thinking about me as she sits on the bus beforehand.
"That's a good girl. You know, perhaps I married the wrong sister. But hey, you're not as submissive as Sylvia."
I'm pinching and pulling on her nipples which I know she likes but her first orgasm takes me by surprise. I'm nowhere near ready to come yet. She must be really getting off on this. I wonder if it's the thought of cheating on her husband and her sister that gets her going. I've fucked her five times now and that's what we agreed to pay off the loan.
Gradually she slows up as she comes down from her orgasm.
"Hey my turn now, so get your ass moving."
She starts bouncing harder and I can see she's getting into it again. We must have been fucking for the best part of half an hour by the time I'm ready to let go of my load. I pride myself on the quantity of spunk I shoot. The randy bitch orgasms a second time as she feels me spurt inside her. I'm feeling good now and after I've pulled out I reach over and pass her a handful of tissues to stem the flow. I slap her hard on her ass as she stands up. She snatches her dress up off the floor and heads to the bathroom.
"Run me a bath," I shout up the stairs.
I hear the bath running, then she's back just standing there. I can see she wants to say something but can't seem to spit it out. I give her a wink and move over to her, cock still hanging out of my trousers.
"You know, now you've paid off the loan you don't need to come here."
I can tell she hates herself but doesn't want it to end there.
"Okay, but I could do with a bit more cash, in the future I mean."
I smile and nod, "You know, if you want to carry on seeing me, you can come round next Thursday, and don't use a loan as an excuse, you've got money. If you want a fuck, just come and get it."
I can tell she wants to but can't bring herself to say it so I just slap her on the ass again as I head upstairs to the bathroom.
Three hours later.
"It's me I'm home. Oh was Julie here? That's her scarf on the sofa."
"Yeah, the stuck up bitch came round to talk to you."
"Don't call her that, I know you two don't get on."
"Sorry babe, I've just missed you. What's up?"
"Well she knows I work Thursday."
"Well I guess she forgot."
"You were nice to her weren't you, you didn't upset her?"
"Of course not Sylvia. We sort of got on better, well when she left she was okay, sort of happy I guess."
"Good I'm glad you two are finally getting on."
"Well she is trying her best. Oh speaking of trying her best your mum came round this afternoon. She asked if she could borrow some money off of me."
"Oh?"
