It had been a hot sunny summer and I'd been using every opportunity to ogle the two young blonde beauties next door. They were Becky, just turned nineteen and about to go to university, and nearly twenty one year old Debbie back from university for summer, both at home with their parents.
Most afternoons that summer they'd been sunbathing in their garden in microscopic bikinis displaying the kind of perfect figures only girls that age have. Our upstairs bedroom window overlooked their garden. Making sure my wife didn't catch me, through my high power binoculars I'd explored every millimetre of their young bodies. My hungry eyes had enjoyed long shapely legs, firm young breasts all but oozing out of skimpy bikini tops, and hints of vagina slits under the thin cloth of tiny bikini bottoms.
I masturbated thinking of what I'd like to do with them. Sometimes when I fucked my wife, in my mind it was Becky's or Debbie's naked body under me. I'd thought my sex fantasies about them were as far as it would go, then one weekend events combined to create the perfect opportunity, for all three of us.
My wife was away for a few days looking after her aged mother. Mid-morning the doorbell rang. I opened the door and there on my doorstep were Becky and Debbie. In the few seconds before they spoke my eyes involuntarily explored them.
Becky was in a thin shoulder-strapped bright-patterned sun dress high up her bare thighs and making it obvious her big breasts weren't in a bra, with her long blonde hair cascading over her shoulders. There was a big grin on her sweet young face. Older sister Debbie had her hair tied back in a loose pony tail and was in a red sleeveless boob-clinging top, again obviously with no bra, and very brief white shorts as tight over her pussy bulge as her bikini had been.
They glanced at each other as if confirming something they had previously decided, then Debbie spoke.
"If we take all our clothes off for you will you show us your cock?"
Her voice was calm and determined. Becky giggled excitedly and said:
"I've never seen a man's cock before."
"Come on," Debbie continued. "You've been watching us all week in our bikinis. I'll bet you've been wanking thinking of us." I felt my face go red. I certainly had. "You want to see us nude don't you? Our parents are out shopping. Now's your chance, if you want."
As Debbie spoke my eyes followed her hand as she swayed her hips sensuously and reached down to lightly finger her pussy through her shorts in case I'd missed the message.
I wanted! I wasn't turning down an invitation like that. A couple of minutes later I was with the girls up in Becky's bedroom. It was a typical girl's bedroom with lots of pink and a pile of fluffy toys. We were hardly in the room before Becky slipped the string-thin straps of her dress off her shoulders, slid her dress down her body, let it drop down her legs and kicked it aside.
Underneath she was just in tiny white cotton panties sheer enough to show the shadow of her cunt bush through. A moment later she'd dropped her panties and stepped out of them.
As soon as her panties were off, standing there she spread her legs wide and arched her back to thrust her hips forward and to swing her breasts up and out. She put her arms behind her back as if to prevent any part of her obstructing my view of her naked body.
"Do you like my body? I've never shown myself nude to a boy." As she spoke she rocked her hips smoothly, setting her breasts swinging.
Her young naked body was everything I'd dreamed of: superb legs, firm young breasts with deep pink nipples, and an untrimmed bush of light brown hair between her legs, all as delicious as anything I'd ever ogled myself in porn. Before I could give her the obvious reply Becky continued excitedly:
"Touch me between my legs! Feel my pussy!" As she spoke she jerked her hips toward me.
An instant later my hand was cupped over Becky's cunt mound ruffling her pubic hair, so much softer than my wife's. She nuzzled her pussy against my hand and gasped:
"Yes! Yes!"
with excitement as I slipped my fingers between the juice-moistened lips of her vagina.
My other hand found her thigh, and a moment later I was behind her caressing the smooth cheeks of her bottom, exploring the valley between them and reaching under her between her spread legs to tease her from behind. It had been years since I'd played with a girl so young. I let my frantically exploring hands make abundantly clear that I liked her naked body, and how! She gasped, squealed and moaned with excitement.
"Now my tits!" Becky cried out.
I hardly needed to be asked. Becky's breasts were smaller but rounder and firmer than my wife's. Her young nipples were up with arousal like deep pink corks. She gasped with excitement and pleasure as I ran my hands over them, then she squealed wildly as I licked her nipples and flicked them with my tongue at the same time as I fondled her cunt with my fingers.
As I played with Becky, Debbie stripped too. She was just wearing that top and her shorts, with no underwear. Her naked young body was every bit as exquisite as her younger sister's, with slightly bigger breasts, and her cunt hair was trimmed into a neat strip around her vagina slit.
Becky stepped back from me, sliding out of my exploring hands and squealing:
"Come on! Now let's see your cock!"
She was all but bouncing up and down with excitement. I'd already decided I was going to treat them to more than just showing them my straining hard erection. I started to unbutton my shirt. As soon as it was off Becky was in front of me running her fingers over my bare chest. She was so close to me her nipples were brushing against me. The girls watched as I took my trousers off. Underneath I was in light blue briefs only just big enough to cover my erect cock. My straining penis was pushing them out in a huge bulge with my cock fur showing at the sides where my cock pushed my briefs away from my body.
I stood there in my briefs and thrust my hips toward Becky, inviting her to pull them down. In a moment she had them down round my thighs and my erect cock bounced out. Seven inches of hard muscle, almost fully erect, stuck out just above horizontally in front of me above my thickly-haired balls. I let my briefs fall. I spread my legs wide and thrust my hips toward Becky like she'd done for me. I swung my shaft at her. Becky gasped:
"Oh! It's huge! You'd never get that up my vagina!"
I was sure I could with her legs wide and some good hard thrusting, but I didn't say anything. Though I'm more than twice Debbie's age I keep myself fit and I knew I was nothing to be ashamed of. Becky's hands were all over me, running through my thick pubic hair, caressing my balls, feeling and stroking my cock. As her hands explored me her naked body brushed against mine and my hands roamed over her. Within moments my penis was straining hard, taut with that exquisite feeling of full erection.
Becky looked at Debbie, who'd been standing watching her little sister playing with me, as if a thought had just come into her pretty little head.
"Debbie," she began, "you said you'd show me how to do sucking off, like Annie says she does for Dave."
I had no idea who Annie and Dave were, but he sounded like a lucky boy. Debbie stepped forward and stood next to me. My hands instantly started exploring her naked young body.
