If wife sharing isn't your thing I suggest you pass on by. This is a quick story that may be followed up.
Rachel and I are in bed, spooning. It has been a hard day. An early run, an extended family lunch, a dog walk and Netflix. We idly chat about the day. As I lay there my cock twitches on her naked butt. It always does. She knows that. It's never failed to happen. She lazily says, "I'm tired. Do you mind if I just lay here?"
"Cum on me by all means."
It doesn't take long. I jerk off with our skin touching across the length our bodies and the smell of her in my nostrils. I love the smell of her hair. I come between her legs partly on her pussy, more in her ass crack than anywhere. She laughs and whispers, "That was nice. Now massage it into my pussy and ass. I can't be bothered to get up and towel off."
I do as I am asked and play my fingers into the warm cum and lead it down her ass, over her sphincter and onto her pussy. Her pussy arch's slightly towards my fingers and I play it round her pussy for a full five minutes. I begin to think she has drifted off to sleep, but then something cold touches my fingers. Rachel is pushing one of her sex toys to me from her belly. It is the bell-end that's rubbing against my wet fingers, pushing my fingers off her pussy as it claims her. I rub cum on it and push the tip into her hot hole. She giggles and in a mock moan whispers, "Cuck. Help him in."
I do and take over guiding the dildo into her. I nudge it in slowly making sure that it is wet and slides in without beaching any dry latex on her lips. Once it is mostly in, I gently change the angle and press it into her g-spot. I reach around to press her belly into it to maximise the effect. I am careful not to press on her bladder. Rachel murmurs appreciative noises and asks, "How does it feel having another man use your cum as lubricant?"
I am surprised by her wantonness and confused too, I had thought she was all tired out. Apparently not. Rachel rocks slightly back and forth. After a few minutes her breathing gives away her approaching orgasm and I realise from her movements that is tweaking her own nipples to drive her over the edge. She comes quietly and after taking a moment rolls onto her stomach, the dildo still in place. I stare at it for a moment, wondering what to do with it next. Rachel turns her face to me, sweeps her hair away and kisses me softly, "I didn't know I needed that. I'm going to do something for you now."
I say, "How can I refuse."
Now the whole experience has been great. However I have cum once already, so I am not sure I can follow that so soon. I am at least semi-hard, but will need some encouragement to cum again.
Rachel whispers to me, " I'm going to fuck a big cock with your help. I want you to find a big cock! 9 inches at least and thick too. Can you do that? Would you like that?"
I reply, "That would be a giggle. I'd love to see your eyes pop out as you meet a monster like that."
"Get the big cock sleeve and I will show what I have in mind", is her instant reply.
I roll out of bed and focus on not losing the erection I do have whilst I collect and lubricate the toy she wants. I give it to her and she shakes her head, "Put it on silly."
As I put it on, my hard-on begins to return. Seeing my success Rachel rolls over and raises her ass slightly. Her pussy is now pouting at me.
"Surely it not cheating if I only take a big cock doggy style?" she asks.
"I think I read that's correct in Cuck Weekly," I reply.
