The very thought of Viv sucking my cock to completion had my pulse racing.
Viv put her hand on my chest and used it to push herself up on all fours. She paused, looking down at me, her heavy breasts only inches from my face. I craned my neck so that I could reach them with my mouth. Viv lowered herself to make it easier.
I sucked the nearest nipple, getting as much as I could of her soft breast into my mouth. The other breast I caressed with my other hand, my thumb rubbing that nipple.
Viv's hand traced down my chest and stomach, between my legs and around my hardening cock. I started growing more in her hand as she stroked me.
"I..., I've never done this before."
"I know, but from the way you cleaned me up just now, I think it'll come naturally to you."
She smiled and instead of scooting down the bed she turned around, giving me a glorious view of her pussy and bum. Her breasts were now pressing against me, warm, soft and cushioning out. She held my cock vertically by the base and closed her warm mouth over the end.
"Oh yes Viv."
I cupped my hand over her smooth bum and squeezed and stroked it. Her thighs were together, so her outer pussy lips formed a clamshell, her inner lips protruding, her anus clearly visible. I stroked my thumb down her slit.
"Mmm," she murmured on my cock.
She still had just the tip of my cock in her mouth but her tongue was moving around the head, giving me waves of pleasure. She momentarily released me with a pop!
"Am I doing it right?" she panted, (she'd been holding her breath.)
"Oh yes, what you were doing with your tongue was fantastic. You could try taking more of me in your mouth, just be careful of your teeth. Then move up and down so I'm fucking your mouth. Then mix it up and go back to doing just the tip and perhaps wanking the exposed part of my cock as you do that. You could lick my shaft and balls, like you did when you were cleaning me, that felt really good too.
Just remember to breathe through your nose and do whatever you feel like doing.
I love this view of your rear end by the way, you're so goddamn sexy"
She'd got her breath back somewhat, "I thought you might, I just love exposing my private parts to you." she took a deep breath and went back down on me.
It all came naturally to her, the only thing more she could have done was deep throat me, but there would be another time for that.
I was in heaven, at one point she'd drawn my foreskin right back and was flicking her tongue on my cockhead near that rib of tight skin. I was stroking the side of her breast with the backs of my fingers of one hand and the thumb of my other hand was in her vagina, the index finger rubbing her rosebud.
"I'm ready to come!" I warned.
"Mmm mmm!" she acknowledged and started bobbing her head up and down rapidly.
My orgasm overtook me and I held her head as my cum spurted into her mouth. I'd already come once, so it wasn't so forceful, but some still leaked out.
When she was sure I'd finished she lifted her head. I saw her throat move as she swallowed and then she caught the dribble on her chin and sucked it off her finger.
"How was that?"
"Absolutely wonderful!" I gasped, "You are a natural."
"It makes me feel so close to you, doing that, I want to do that for you more often."
"I'll always let you," I then said, "what we can also try is for us to start in the same position, but then you swing your leg over me, so I can lick your pussy at the same time. It's called the 69 position."
"69?"
"Think of how the numbers six and nine look when written next to each other, like ying and yang."
"Oh, I see, yes, ooh I'd really love that!"
She kissed me and I could taste my cum in her mouth.
We pulled the quilt back over us, I was on my back, she was laid on her side with one leg over me, holding my cock in her hand. Not moving her hand, just holding me to be intimate and close.
It felt surreal, only a month before, she was just my mother in law, my wife's mother. Now she's my lover with a voracious appetite for sex. Her lively, warm body lying next to me in her marital bed, I needed to be careful on that front. I couldn't keep going home shagged out when I was on the early shift. Late shift wasn't a problem, as I'd have plenty of time to recover at work.
I explained this to Viv, she understood and we agreed we'd do Tuesdays and Thursdays when I was on earlies, but we'd start the next day, so she could have me three days that first week!
It was obvious there was no jealousy from her regarding Yvonne and me, nor for that matter would I be jealous of her and Phillip, if they were still having sex. I then had an idea.
"Do you think now that you know you can have full sex, you should try again with Phillip,"
"Whoa...! WHAT!" she exploded, sitting up and glaring at me, "Are you pushing me away?"
I held up my hands, taken aback by her vociferous reaction, but then understanding it, "No, no, no, nothing like that, please, hear me out.
Just as you are not jealous of Yvonne and I, nor am I with you and Phillip. It's going to be hard for this changed, fulfilled, radiant, happy Viv, to still be the normal Viv around Phillip and Yvonne. Sooner or later one of them will pick up on it and suspect you of having an affair, perhaps not with me, but they will if you don't mask it when you're around me.
This way your excuse is your rejuvenated sex life with Phillip."
"Oh yes, I see what you mean now... God you had me worried! I don't think of him like that any more and I don't want to. I have you now. Anyway, how would I explain the fact I can now do it when I couldn't before?"
"Well it would also give you chance to come clean about why you pretended to be in poor health, so you don't have to keep doing so. I just think it's going to be a strain on you to keep up that deception.
As for how do you explain, you could say you read an article in Cosmopolitan regarding the g-spot and take it from there.
Just make it absolutely clear to him there can be no more wham, bam, thank you ma'am."
"I'll think about it and how best to approach it."
She lay back down and we cuddled and chatted. I left soon after.
I was home well before Yvonne and prepared a meal for us ready for when she got home.
