When Uncle Bob's car was missing from the drive, I just walked around to the garden of the house and let myself in at the back door, which Rae loves because it brings an element of spontaneity, and I've walked in on her while she's engaged in some kind of sexual activity either alone (mostly) or in company (the gardener, once) on several occasions.
Today I found Rae dozing by the pool, her tanned body stretched luxuriantly on a lounger in the afternoon sun, hands above her head, sunglasses on, and an open paperback on the grass where it had fallen. Rae was wearing a white bikini, barely large enough to cover her, especially with her legs flopped open as they were now.
As I stood there, gaping a little as I always do when I see her naked, or nearly, she sensed my presence.
"Ah, Danny boy! Good afternoon," she said, stretching as she came back to life.
Pulling her sunglasses down to the end of her nose briefly, she looked at my tenting shorts, and then at my face, smiling.
"I do love to see that. Oh, and you, obviously," she added with a chuckle.
Laying back down, allowing her legs to part again as her thighs fell open, Rae continued looking at me over her sunglasses.
"I'd like you to cum over me," Rae said, casually.
My cock jumped in my shorts. I didn't need any clarification or encouragement. I wouldn't be surprised by anything Rae said by now.
"I really want to see your cum squirt from your cock and onto me, from this angle beneath you," she added.
I pulled my cock out of my shorts and began to stroke, my eyes never leaving Rae's.
"Shorts down, Danny, I want to see your balls when you cum -- and stop stroking. I don't want you to touch your cock at all."
Not processing the second part of her instruction, I pushed my shorts to my thighs, neither of us caring what the voyeur neighbour saw, these days, we just hoped it got him off, and took hold of my hard cock again.
"No, Danny, I said don't touch yourself please, just stand over me and let it happen," said Rae.
I wasn't sure if I could cum like that, and told her so, but Rae said "You have wet dreams about me, you tell me all the time, right? So this is no different, you're just awake, that's all. Humour me."
I stood over her, casting a shadow on her as she reached behind her neck and pulled the bow, letting her bikini top fall away, exposing her glorious tits, their nipples standing erect and tall.
Still looking at me, Rae pulled the bow at her hip apart and tossed her bikini bottoms onto the grass, her parted thighs exposing her waxed cunt, which was clearly wet, glistening in the sun from my vantage point.
For the next 5 minutes, we said nothing. I stood over Rae, my cock hard as iron and pointing to the sky, rigid and flat against my stomach. Rae never took her eyes off mine.
I heard Rae inhale sharply and realised pre-cum had started to trickle from my cock, falling in a thin string to the grass below me.
I moved closer, my feet under the lounger, and, amazed, felt my cock start to pulse and my balls begin to contract.
Resisting the almost overwhelming urge to touch my cock, I started to cum.
Rae said, biting her lip "Oh fuck.." and, not touching herself either, pulled her knees up, rubbing her thighs together, having her orgasm as the first heavy cum fell from my cock to her chest, white against her tanned skin.
As I began to cum properly, I was pumping too hard and I was missing Rae's body, sending cum arching over her to the grass beyond.
Urgently, cumming, breathing hard, Rae said "Stand at the end!"
I moved, cum still leaving my cock in heavy, regular streams, and stood quickly at her feet, straddling the lounger. Rae sat up and tossed her sunglasses aside.
All my remaining cum hit Rae, mostly her upper chest and face, some in her hair.
Rae moaned softly, muttering "Jesus Christ that's good." to herself at one stage, tilting her face upward as if to catch the sun.
When I stopped cumming, the remainder of it hanging in a thick, white line from the end of my softening cock, which still jerked spasmodically every few seconds, Rae stood, allowing cum to run from her neck to her cleavage, and from her stomach to her thighs, and, taking my hand, announced brightly "Come on, we're going to see a movie."
After Rae showered and dressed in her usual shirt, sleeves rolled up to her forearms and unbuttoned so that pretty much her entire cleavage was visible, small and delicate though it was, and cut-off jeans (one of my all-time favourite looks on her), we got in her car, Rae pushed a button to lower the roof, and we made the 30-minute drive to the cinema.
On the way, Rae wanted to expand a little on the partner-sharing lifestyle she and Bob, my uncle, enjoyed. I knew that Bob was the instigator, obsessed with seeing other men fuck his gorgeous wife, but I was surprised at how passionately Rae talked about it -- she was clearly very much into it too.
Rae told me that the orgasms she had with a stranger's cock inside her could be immense -- she'd nearly fainted once when she was in the middle of a violent orgasm and she'd heard Bob tell the guy she was fucking "pull that fucking condom off and cum inside her cunt."
They didn't like arranged meet-ups with other members of the "swinging" community and neither did they consider themselves part of a cuckold scene -- this was about their mutual pleasure and any humiliation of Bob was a turn-off for them both, so they didn't get involved in what Rae called "that whole craziness."
Strangers were the thing that did it for them, particularly pick-ups from bars and business hotel lounges. Bob and Rae would say they were friends or brother and sister and Bob would melt into the shadows when a guy started to flirt with Rae.
