Though I'm a married man in my early forties, I like wearing sexy women's panties. I love the look of them on my otherwise naked body and how the thin, taut material shows off my erect cock outline. I'm into porn, and as well as pictures of naked women, nothing turns me on more than the sight of a well-stacked guy with his hard-up cock in women's panties.

One weekend, my wife was away seeing her ageing mother, and my nineteen-year-old daughter was away with friends. So, on the Saturday afternoon, I was at our local supermarket indulging my fetish by buying a couple of pairs of women's panties. Fortunately, our supermarket has recently installed self-service tills, so I can buy anonymously without having to run my purchases past a checkout girl.

I was walking across the car park to my car when I heard a man's voice behind me.

“Did you buy those panties for yourself or for your wife?”

I stopped in my tracks, horrified. I'd been spotted. I turned. There was one of our neighbours, Clive. I meet him most mornings on the station platform for our commute up to town. He's about my age, slim and muscular, with a thin clean-shaven face, neat dark hair and glasses that give him a professional look. He's always smartly dressed and that day he was in a light grey sports shirt, blue jeans and white trainers. He lives in a flat down our road. I'd picked up that he was unmarried.

Before I could say anything, Clive stepped into a gap between two parked cars, shielding him from being seen by any one but me. He quickly unzipped and unbuttoned his jeans and pulled them a little way down his bare thighs. I saw he was wearing women's panties. They were in pastel pink cotton with red embroidery at the hems. They were very brief and were bulging over what was obviously a hefty package. As I stared at him, he quickly pulled down the front. His penis was semi-erect. He nudged his hips toward me, sending his penis swinging.

I don't know what came over me. Perhaps it was because my sex life with my wife had become bland of late. Perhaps it was because deep down I wanted something different and kinky. Perhaps I'd been aroused too many times by the sight of men posing erotically in women's underwear. Perhaps it was because back at my all-boys school at eighteen, my earliest sexual experiences had been cock play with other boys as sex-mad and frustrated as me. I'd never forgotten the guilty erotic thrill of those school days.

For whatever reason, I just couldn't resist. I reached down, cupped my hand under Clive's soft warm balls and ruffled his pubic hair. It was coarser than my wife's hairy pussy. I ran my fingers along his steadily stiffening penis shaft and fingered its big, soft head. Clive growled softly and nuzzled his cock and balls against my exploring hand.

“Are you wearing panties too?” Clive asked.

I'd gone too far to turn back. I'd touched and fondled another man sexually, and I’d enjoyed it. I unzipped and dropped my own tan-coloured chinos, lifted my blue shirt and spread my legs. I was wearing a pair of my daughter's panties. They were light grey silky-smooth satin with a little white flower pattern. By then, my own cock was fully erect. My daughter's panties were bulging in a ridge over my shaft with the thin cloth showing the outline of my shaft and cock head in fine detail.

Clive's hand was instantly down between my legs, caressing my balls and exploring the outline of my erection through the thin cloth. At his touch I felt a burst of an exciting, erotic, guilty pleasure I hadn't known since those boys in my school days. Watching his exploring hand on my panties, I saw a wet patch of pre-cum where the grey satin bulged over the big round head of my penis. I wanted more. But a supermarket car park was hardly the place for a sexual encounter.

“Shall we go back to my place?” I asked. “My wife and daughter are away for the weekend.”

Clive was on foot, and I took him back to my house in my car. We went straight up to our main bedroom. We stripped quickly to just our panties. Clive loved how my daughter's panties were just a thin thong gusset at the back nestling deep in the valley between my bum cheeks. I bent over and spread my legs for him to run his fingertips along the thin gusset from behind. He reached right under me to stroke my anus, balls and shaft through my panties. The bulging ridge and the wet patch were much bigger after he'd done that!

We pulled our panties aside to show each other our penises. Clive was uncut, unlike me, and his cock head was fully out. He'd shaved his pubic hair to just a dainty ring round the base of his cock. His about seven-inch-long penis was a bit bigger than mine. My balls are very hairy, my straining cock was sticking up every bit as hard as his, and my erection-swollen cock head was bigger and more prominent than his.

“Have you done much with guys before?” Clive asked.

I told him about my times at school, how I’d masturbated together with other boys, how we'd hand-jobbed each other and rubbed our excited young cocks together to cum. Clive told me he'd had women and had only recently started going with men.

Clive suddenly squatted down in front of me so his face was level with my panties. He pulled my panties aside so my penis bobbed out and stuck up in front of him. Clive lightly kissed my cock head then licked his tongue over it and up and down the length of my shaft. Then he took just the head of my penis into his mouth and massaged it with his lips and tongue. I involuntarily tried to thrust my penis as deep as I could into his mouth.

But after a minute or so of exquisite oral pleasure his lips slipped off my quivering hard cock. Still squatting in front of me he looked up at me.

“Would you like me to suck you off?” he asked.

But I declined. I love masturbating through women's panties. There was one thing I wanted more than anything else. I wanted someone to masturbate me through panties.

“Wank me through my panties,” I said.

I put my cock back into my daughter's panties and adjusted it so that the big ridge bulged again. My cock head came up almost to the top hem. I leaned back against a chair, thrusting my hips forward and spreading my legs wide. I braced myself for pleasure.

Clive stood beside me, his legs astride mine. His panty-sheathed penis head poked and brushed against my naked thigh. I pulled his panties as far down his legs as the taut material stretched around his thighs would allow. Now his penis and balls were naked to poke against me and for my hand to play with them and his buttocks.

Clive's hand started on my thigh, stroking my so sensitive inside thigh tops, then my groins. His other hand stroked my own buttocks along the gusset of my daughter's panties. He caressed my balls through the thin cloth then slipped his hand through the gap where my straining erection had pushed my panties away from my body to briefly play with my naked penis.

Then his fingers crooked over my penis ridge and he began the slow, rhythmic full-length stroking from my balls to his hand, sliding over the bulge of my cock head. I played with Clive’s buttocks, balls and penis as he pleasured me. I didn't take long to climax. As my orgasm rose Clive would have felt my shaft suddenly harden even more against his hand. In any case, my grunt, how my hips rammed forward and how I gripped his bum to pull him against me would have told him I was coming. His stroking hand slowed down in the last moments, stroking just across the ridge where my shaft meets my cock head. I juddered and cried out as my penis exploded in pulses of orgasm pleasure. A massive wet patch of spurted cum appeared on my daughter’s panties, soaking them with semen.

I flopped, panting, then slipped off my daughter’s semen-soaked panties and threw them aside. I stood there with my naked, still half-erect penis swinging as it dripped a long strand of semen onto the carpeted floor.

Clive’s penis was almost vertical. I closed my thumb and forefinger round his shaft just below its head. It had been years, back at school, since I’d hand-jobbed another boy. Since then, I’d only wanked my own penis secretly without my wife knowing. Clive’s shaft was as hard as those excited boys long ago. The once so familiar motion came back to me straight away even after all the years. I began to tug Clive’s foreskin up and down. But Clive took my hand to stop me. He had other ideas too.

He told me he posted pictures of himself in erotic poses in panties and naked on porn social media sites. He mentioned a few. I knew most of them. In fact, I post erotic pictures of my own cock on them, but I didn’t tell Clive. He asked me if I’d take some pictures of him on his phone for him to post. I certainly would. We went into our spare bedroom. It’s a fairly nondescript room that couldn’t be easily identified and for good measure, we moved a few things out of sight.

Clive was still in his pastel pink panties. I had an idea. There were some of my wife’s and my daughter’s used panties in their laundry baskets. I knew some of my daughter’s panties were a lot briefer and sexier than Clive’s pink ones. We rummaged through their laundry, and Clive tried on lots of pairs, enjoying looking at and sniffing the stains.

Clive settled on a pair of the simple white cotton knickers my daughter wore at school till recently. They were much briefer than school regulations allowed. His erect cock only just fitted into them. They scarcely covered any of his backside, and I agreed the white cloth looked good against his tanned skin. Clive especially liked how one of my daughter's dark pubic hairs had got caught in the stitching.

As I clicked away on his phone, Clive posed in my daughter’s schoolgirl panties and then nude. He poked his cock out so her panties bulged in a big cone over the rounded apex of his cock head. He pulled them aside to show his naked ass and so his balls showed and his big stiff cock stuck out. He pulled her panties down round his thighs to erotically underline his upward-bending cock.

Naked, he squatted, knelt and lay back on the bed, spreading his legs and thrusting his cock. He got on all fours with his legs wide and his balls and cock swinging under him. I got some incredibly kinky shots, including zooming in on his bulging panties, on his swinging genitals, and looking straight up between his legs at his anus, and lots, lots more. After I’d taken lots of penis-straining shots, Clive looked at me.

“Video me jerking one off over her knickers!” Clive said excitedly, fingering his cock.

He got into a kneeling position naked on the bed with his legs wide and his erect cock poking straight out in front of him. It’s one of my favourite wanking positions too. I love the heavy feel of my erect cock sticking out and how my balls hang. I fantasize about my wife running her hand under me from behind when I wank like that so I slid my hand under Clive from behind. He liked it too. I switched his phone to video and got ready.

“Ready,” I said.

Clive started fingering his cock the way men do to work their cocks to the peak of erection stiffness and pleasure sensitivity in readiness. He picked my daughter’s white panties from the bed. He brushed them over his penis and balls and ran them under him between his spread legs the way I do when I play with my wife’s and daughter’s panties. I heard him growl softly with arousal and sexual pleasure. I moved round him, catching him from every angle, including his ass. I zoomed in on his cock. Its shaft was gleaming smooth with its veins standing out, and its erection-swollen head was almost glowing purple.

With the camera aimed at him Clive wrapped his hand round his straining shaft and began to tug rhythmically up and down. His hand slid right up over his cock head and down to his ring of cock fur. I hadn’t watched anyone jerk off since my schooldays and I’d forgotten what an erotic sight if was. He thrust his hips and grunted with sexual pleasure as he masturbated. As he wanked, he continued to brush my daughter’s panties over his cock head. He paused, edging as he held back on the exquisite, almost agonising, brink of orgasm. Finally, he grunted:

“Coming!”

His buttocks clenched and his face twisted in the ecstasy of his orgasm. In the final moments before he came, he held my daughter’s white cotton schoolgirl panties in front of his cock head. He grunted loudly and his naked body juddered as his semen spurted over the white cotton. I stayed videoing him with the camera aimed at his swinging flaccid cock, dripping residual semen onto the bed.

“Did you get all that?” Clive asked.

“Right to the last spurt of cum,” I replied.

Clive fell onto his back on the bed. His penis flopped onto his belly, oozing semen. He spread his legs wide.

“Cum over me!” he gasped.

I hardly needed to be asked. After seeing him pose in panties and nude, and watching him wank, my own cock was up, rock hard. I was frantic to jerk one. I climbed astride Clive’s slim waist, wetting my balls with his semen which had trickled over his belly from his cock. My cock arched up over him.

I began to masturbate. Clive’s penis was stiffening again and was poking into my ass crack. As I methodically pumped my shaft, Clive’s hand reached down to lightly stroke the insides of my spread thighs and to reach under me to finger my anus. He certainly knew how a guy likes to be touched.

I didn’t bother to edge but just stroked myself through. I spurted a hefty load over Clive’s belly and his chest. Afterwards, I stayed astride him for a moment with my sagged penis dripping semen onto him. My spurted semen was trickling down his sides toward the bedclothes. So I gave my daughter’s white cotton panties a second soaking of semen as I used them to wipe my spurted cum off Clive's naked body.

After that, Clive and I showered together. We didn't bother to get dressed but just put on some of my daughter's panties. We posted the hottest pictures I'd taken and that video on his porn media sites. Then we browsed porn together and hand-jobbed each other to cum. By then, it was early evening. Clive asked me if I had any plans for the evening. I hadn't.

“There's an adult cinema up in town I go to,” Clive said. “I go there to meet guys, if you know what I mean.” By then, I knew what he meant. “You'd be very welcome.”

“Let’s go,” I said.

That might be another story.
