Having been married for 15 years, I thought I knew my husband. I thought I knew myself, for that matter.

But even at the age of 44, life can still have erotic surprises for you. If you’re lucky.

Exercise and sane eating habits had let me keep my fit figure into what was now, undeniably, my middle age. I was proud of the shape I was in, my tits and ass were still firm, though I wasn’t really trying to impress anybody except Roger, my husband.

I worked at a big advertising agency. I was good at what I did, but sometimes it was awfully time-consuming. Even so, I grew gradually aware that something was off with Roger. He’d been acting strangely.

We had a fine sex life. Roger had stayed in good physical shape as well, and he could still get me wonderfully hot and bothered with just a look.

One night in bed, though, he seemed particularly distant, like his mind was elsewhere as he plowed me with his cock. I enjoyed it anyway as I was swept up into a familiar climax, feeling his cream warm me inside as he came as well. But as we lay together afterward I nudged him.

“Rog… is something going on with you?”

He got defensive, way out of proportion to the question. He said he’d been busy at his own job and we just hadn’t been seeing each other enough. I let it go.

But we had been married a long time, and you get so you can sense things. Even though I knew Roger loved me, I wouldn’t put it past him to have an affair. The thought didn’t tear me apart with jealousy, but I did want to know the truth.

I started to do some unaccustomed snooping. It was distracting and even demoralizing. I actually found myself caring less and less if Roger was fucking some other woman. At some point, I just wanted him to come clean about it.

A young woman named Amanda, who worked in my office, noticed my mood. “Mrs. K, are you all right?” she asked me.

“Call me Zoe, Amanda.”

She smiled at that. She was a pert thing, with nice tits, gorgeous hair and a pretty face. I recalled she’d been working there about two months and always seemed to be by my side, offering help. I’d figured she was looking for a promotion.

Somehow that day her concern hit me when I was most vulnerable. We were alone in my office, and I started talking. Then I couldn’t stop. Soon I’d babbled my suspicions about Roger.

Amanda bit her lip and looked at the floor. I thought I had embarrassed her — and myself — but she said quietly, “I’m afraid I know something about that, Mrs. — Zoe. Can you come to my place after work?”

The moment was like something from a mystery novel. I got back to work and stayed at the office until evening. When I left, Amanda was already gone from her desk. Curious, I drove to the address she’d given me and knocked on her apartment door.

“She was whimpering with need as I got my first taste of her cunt.”

She let me in, wearing a slinky robe. There were candles burning and soft music playing. I was more puzzled than ever as she had me sit while she stood, looking nervous.

Finally, she said, “Okay. I don’t know how you’re going to take this but… ” She bit her lip again, which gave her a cute “naughty girl” look. “But I’m the one your husband has been sleeping with.”

I would have thought, under those circumstances, that my response would have been a lot more violent. Maybe 10 years ago it would have been. But I was older and wiser. I eyed the attractive woman who was probably half my age.

In a steady voice, fixing her with a cold eye, I asked, “Why?” I wanted her to have to explain. I wanted, at least, to see her squirm as she told me why she was intruding into my marriage.

But I didn’t see her answer coming. Quite frankly, it stunned me.

Amanda said, “I slept with him because it was as close as I could get to sex with you.” She blushed.

My mouth dropped open. I don’t think I’d ever been so shocked in my life. But even as I reeled from that bombshell, I thought back over the past two months. Amanda hadn’t just been helpful around the office. She’d been downright flirty, giving me smoldering looks and offering endless compliments.

With the look of somebody going off the high dive, she pulled her robe’s sash and dropped the garment on the rug. She stood nude before me.

I was still gaping, but now it was at the sight of this perky young thing on full display. Her tits were high and full, capped with pink nipples the color of cake frosting. Her body was richly tanned, supple and silky-skinned.

Desire was hot in my throat. Before Roger, I’d had a few girl/girl experiences and had enjoyed them immensely. But I thought all that was behind me.

Apparently not.

Finding courage from the lust in my gaze, Amanda turned in a circle. I stared in wonder at her brash little ass. It looked so enticing I wanted to sink my teeth into it.

When she faced me again, she said in a pleading voice, “Will you let me fuck you, Zoe? Please. Please!”

Now I did react violently, but it was in a fury of overwhelming desire. I launched up off the couch and grabbed the naked young woman. She melted in my arms as our mouths crashed together, delivering a jolt of pure pleasure. She kissed me back madly, tugging at my clothes as she groaned deep in her throat.

After my clothing was flung every which way, I pressed my naked body against hers. My hands moved over her smooth flesh. I groped her luscious ass. She mauled my tits, pinching my fiercely hard nipples.

Panting, we finally broke our lip-lock. Her eyes dancing, she took my hand and led me to her bedroom. More candles burned there. We threw moving shadows onto the walls as we spilled onto the bed, wrapped in a new embrace. Her thigh slipped between mine, pressing against my streaming pussy. I cupped her tits, bending to suck on her stiff nipples.

I moved farther down. All my muscle memories of lesbian sex had returned. Savoring the experience, I kissed and licked my way along her body. She spread her legs, and I lay between them, focused on her pussy.

She was already whimpering with need as I got my first true taste of her cunt. I lapped at her moist lips, then speared my tongue deep into her as she bucked on the bed.

I dove inside her, feeling her slick interior. Her clit begged for attention, and I lavished the pulsing bud with my tongue, teasing it with skills I’d half-forgotten I had. Amanda’s fingers wound into my hair. Her hips jerked, and she cried out as she came, her pussy quivering and releasing a delicious rush of juice.

Amanda didn’t need any recovery time. I grinned as she bounced up, shoved me onto my back and scrambled between my legs. I looked down to see her darker face contrast with my paler thighs. Whatever else, it was very heartening to have someone so young attracted to me.

At the first touch of her tongue, my whole body jumped. Roger loved eating me out, but there is something special about a woman’s knowing mouth. Amanda swirled her tongue over my lips. Her hot breath tickled my sensitive skin. When she slid her tongue into me, I clawed the bed on either side of me, feeling delirious.

Like I’d done to her, she toyed with my throbbing clit. She deftly coaxed the bud, fanning the flames of my pleasure. My hips bucked, and I humped up against her face, losing all control. A wild cry tore from me, and I came hard, my body singing with ecstasy.

But Amanda wasn’t done. In a delightful daze I let her turn me over onto my knees, with my ass in the air. Again, I felt her breath on me, this time as her mouth hovered over the valley between my ass cheeks.

Her tongue touched my butt hole and the sensation electrified me all over again. New surges of desire swept through me; I hadn’t had this done to me in ages.

Amanda was fearless as she licked at my pucker. As my muscles relaxed, my pleasure mounted. She wiggled her nimble tongue tip inside my backdoor, while her fingers reached around to toy with my swollen clit. This time I made a fist and beat the bed as a raw cry climbed my throat. My second climax felt like it turned me inside out and upside down; it was glorious.

“Her hips jerked, and she cried out as she came, her pussy quivering.”

“Stay where you are,” Amanda said in an excited voice as she hopped off the bed. I heard her rustling in a drawer. When she knelt behind me again, she said, “Now, let me really fuck you.”

Without looking, I knew she’d strapped on a dildo. The proof I was right came seconds later as I felt the smooth rubber cockhead pushing past my soaked pussy entrance. It was a good-sized piece of hardware, and Amanda was quite talented with it. She penetrated me slowly, letting me enjoy every inch of it.

When she’d sunk herself all the way in, her hands closed over my hips. I always liked it when Roger fucked me hard from behind. I begged, “Fuck me! Fuck me like I’m yours!”

She gave a ragged groan of joy and proceeded to pound my pussy. It felt damn good. I grinned, thinking that this was right. This young woman had been so smitten with me that she’d gone after my husband. My having sex with her now just balanced the scales.

Yet another orgasm was gradually building in me. It mounted, a powerful force. On impulse I called out, “Fuck my ass!”

With another joyful exclamation, Amanda pulled out of my cunt, set the slick cockhead to my well-licked asshole and drove her dick into my back passage. I shuddered with the intrusive elation of it, my body trembling helplessly.

Amanda confessed, “Every time I sucked Roger’s cock, I thought about it being inside you!”

Her words sent me reeling into my climax, with Amanda’s fake cock buried deep in my ass. The day had been full of surprises. I felt like the luckiest woman in the universe.
