Chapter 8

Romantic Sex Story: Chapter 8 - Jim and Aimee have a chance meeting over a jar of peanut butter. In the beginning, he's a married father, she's a college student. That chance meeting in a grocery store, and the coincidence that follows, will change their lives (and others' lives)! I brought this story back to life in late 2025, more than 20 years after I first started writing it.

Preschool programs are supposed to be cute. Harmless. Paper hearts, glue sticks, a few squeaky songs about love that no one over the age of six takes seriously.

But walking into that cafeteria-turned-auditorium on Thursday evening, my stomach already knew better.

Jake and Ethan’s classes had strung red and pink crepe paper everywhere, construction-paper hearts dangling from the ceiling like we’d stepped inside a giant shoebox diorama of Cupid’s frontal assault. Rows of metal folding chairs were packed tight -- parents in jackets, grandparents holding balloon bouquets, toddlers with chocolate on their faces despite no one giving out any chocolate yet.

Beth slipped her hand into mine as we wove through the crowd. Aimee followed just behind us, scanning for seats like she was bracing for an exam.

“There,” Beth whispered, pointing at a row near the middle. Three open chairs.

We slid into them: Aimee on the far side, Beth in the middle, me on her right.

Close enough to feel each other breathe.

Aimee smoothed her skirt, and my eyes followed before I could stop them. Beth tugged her cardigan into place, and the same thing happened again, a reflex I pretended not to have. I sat there trying to look like every other dad in a folding chair -- someone with one life, one lane, one set of rules. But the truth buzzed under my skin the whole time, a low hum I couldn’t shake. I was surrounded, in every sense of the word.

The lights dimmed a little. Parents settled. Paper hearts shivered in the HVAC draft.

Then someone tall -- a dad, built like a defensive tackle -- sat down directly in front of Beth, blocking her entire view of the stage except maybe the upper left corner.

She craned around him once, politely. Twice. Gave up.

I whispered, “Want to switch?”

Beth hesitated -- a reflexive politeness -- but nodded. “Yeah. If you don’t mind.”

So we shuffled:

Beth into my seat.

Me into hers.

Which put me in the middle.

Between them.

Between everything.

In the tight squeeze of metal chairs, their legs brushed mine -- Beth on the right, warm and familiar in denim; Aimee on the left, warm and illicit in cotton leggings under her skirt. The three of us aligned like someone supernatural had sketched a love triangle and decided to make it literal. Cupid? The devil? I wasn’t sure.

The kids marched out, tiny heart antennas bobbing on their heads. A collective awww rippled through the crowd.

But all I felt was heat.

Their thighs touched mine every time someone leaned forward or crossed an ankle or breathed wrong. The music started -- some jaunty preschool anthem about kindness and sharing cookies -- and both of them laughed softly at the same moment.

One sound, in stereo.

I couldn’t breathe.

This is insane, I thought.
This is beautiful.
This is going to destroy us.
This is going to save us.

I didn’t know. I only knew the moment.

Ethan spotted us mid-song and waved so enthusiastically his antenna headband flew off. A classmate picked it up for him with an exaggerated sigh. Their teacher beamed like she’d rehearsed that exact gag.

The audience laughed. Beth laughed. Aimee pressed a hand to her mouth, eyes shining.

I just sat there in the middle of the two women I shouldn’t want this close, legs on fire, heart doing something unhelpful in my ribs.

Halfway through the program, Aimee leaned in slightly -- so slightly she could have blamed the cramped seating if anyone asked -- her hair brushing my arm as she whispered, “Ethan’s so proud of himself.”

Her voice was warm. Soft. Too close.

Beth heard it and smiled, not at me, but at Aimee. Something in her melted a little, that same gentle fondness from the morning waffles and Valentine robots.

I sat there between them, wondering how the hell any of us were supposed to walk back out into the cold afterward and pretend we weren’t burning alive.

When the kids shouted “HAPPY VALENTINE’S DAY!” and took their bows, parents surged forward to take pictures. Beth squeezed my hand. Aimee’s shoulder pressed into mine as she stood. I couldn’t tell if it was accident or intent. My body couldn’t tell the difference.

We made our way toward the front where Ethan was already barreling at us like a sugar-charged missile.

“DADDY! DID YOU SEE MY DANCE?”

“I did,” I said, lifting him. “You were incredible.”

“AMAZING,” Aimee said, kissing the top of his head, her hair brushing my face.

Beth crouched to hug Jake. “You were both perfect,” she said, her voice thick with pride.

Jake introduced us to a couple of friends, who introduced us to their parents, who turned to Aimee with polite smiles.

“Oh! And this must be...?”

We all froze for a second too long.

Aimee opened her mouth, closed it again.

I tried, “Aimee helps us with the boys --”

Beth added, “She’s basically --”

But Ethan -- God bless him or doom him -- finished it loudly:

“She’s part of our family!”

The parents smiled the kind of smile you give when someone else’s kid says something sweet but confusing.

Aimee flushed, but her eyes flicked toward me and Beth -- soft, startled, moved.

We stumbled through the rest of the introductions using vague terms.

Helper.
Lives with us while she’s in school.
Like a sitter, but more.
Family friend.

None of it fit.

None of it was enough.

The boys led us to the cookie table. Beth snapped photos. Aimee wiped icing off Ethan’s cheeks. Jake insisted on showing us his handmade “heart robot,” which Aimee helped him glue together last weekend.

We looked like a family.

A strange, impossible, fragile family.

And I felt it -- the adults orbiting each other, each caught in different gravity.

When the kids drifted toward a craft station, Beth and Aimee stood side by side, watching them. Aimee’s hand brushed Beth’s sleeve; Beth didn’t move away.

I stood behind them, invisible to everyone but the two people I could not safely love.

Something was going to break open tonight. Or soon.

And none of us were ready.


Beth watched the streetlights slip across the windshield in long, thin strokes, like someone dragging a paintbrush across glass. Jim drove with one hand on the wheel, the other resting on his thigh, posture easy enough that anyone would think he was relaxed. She knew him too well for that. His jaw was set just a touch too tight. His eyes flicked to the rearview mirror more often than the road required.

But the back seat ... that was its own universe.

Ethan was leaning over from his booster seat, reenacting his Cupid dance with wild, inaccurate arm movements. Jake kept correcting him, which only made Ethan bigger, louder -- “And then we all had to hold hands and walk in a heart shape, except Ryan messed up and stepped on -- “

“ -- your shoelace, I know,” Aimee said, laughing. “It was a very dramatic moment.”

They were both trying to talk over each other to impress her. They adored her. Of course they did.

Beth twisted slightly toward the back seat, just enough to see Aimee’s face illuminated by the glow of passing traffic -- soft, open, listening with her whole body the way very few adults ever give themselves permission to do around children. She was brushing crumbs off Ethan’s sweater, smoothing Jake’s hair, tucking her knees close, trapped between two car seats and two little boys who wanted every scrap of her attention.

Beth knew that feeling.

Aimee’s laugh filled the car again -- small, genuine, unselfconscious. Beth felt it land somewhere low in her chest. A tug. A warmth. A want.

It was absurd, the way she felt sometimes. She knew that. This girl -- this young woman -- had slipped into their home like sunlight does through a window crack. First you think it’s incidental, then you realize the whole room looks different because of it.

And Beth loved it. Maybe too much.

She glanced at Jim. He gave a little smile at something Jake said, but he wasn’t actually hearing any of it. He was lost in his own head, and Beth didn’t know whether that comforted her or scared her.

Because yes -- there were moments when she wondered. When she caught him watching Aimee with the boys. Or saw some flicker in his expression she couldn’t read. Nothing overt. Nothing damning. Just ... possibility. The kind that makes your stomach tilt.

But every time her mind drifted that way, she shut it down. Hard. Jim wasn’t the one she needed to worry about.

She was.

Because the truth sat quietly in the passenger seat beside her, humming under her ribs:

Aimee made her feel alive again. Not just as a mother. Not just as someone running a household that always needed something. But as a woman.

Beth let that truth wash over her now, warm and frightening.

She looked back again in time to see Aimee kiss the top of Ethan’s head without thinking. A gesture so tender it made Beth’s throat go tight.

What would she do without her?
What would the boys do?
What would Jim do?
What would she do?

“And then, Aimee,” Jake was saying, “did you see the giant cardboard Cupid? It was SO big -- “

“I saw it, sweetie. Hard to miss,” she teased.

Beth smiled despite herself. This was good. This was so, so good. And terrifying in all the ways good things are.

She reached out and rested her hand lightly on Jim’s arm -- not for reassurance, but to tether herself.

“Almost home,” he murmured.

Beth nodded, eyes drifting to the back seat once more.

Aimee’s smile. Her laugh. Her hands in the boys’ hair. The tiny universe forming around all of them, fragile and bright and not at all what Beth had expected from her life at thirty-eight.

And somewhere under the hum of the road and the chatter of her sons, Beth felt it again -- that strange, thrilling shift inside her.

A three-person team, she thought.

Everything works better with three.

And she didn’t know what that meant. Not yet. But she felt it. Clear as the moonlight catching the edge of Aimee’s profile.

Something was changing. And she wasn’t sure she wanted it to stop.


The boys were still vibrating from the program, even in their pajamas. Too much sugar, too much excitement, too much adoration from a cafeteria full of parents.

I read them “Guess How Much I Love You” twice. Ethan elbowed Jake to correct his recitation of the “I love you to the moon” line. Jake retaliated by insisting he could see the moon from the window, even though all you could see was darkness and the reflection of his own face.

Normal chaos. Safe chaos.

By the time they finally drifted into sleep, I was wrung out in that pleasant, parental way -- like I’d spent the whole evening holding everyone else’s joy and now I could finally put it down.

I closed their door quietly and headed for the stairs.

But halfway down, voices -- soft, close -- floated up toward me.

Beth and Aimee.

I paused without meaning to.

Not to spy. Just ... to listen.

“ ... they would’ve been heartbroken,” Beth was saying, voice thick. “Ethan would’ve cried through the whole program if you hadn’t been there.”

Aimee murmured something I couldn’t make out.

Beth sniffed. “I mean it. I don’t know how you’ve become so important to all of us so fast. I don’t ... I don’t understand it. But it’s real. God, it’s so real.”

My hand tightened on the railing.
