He pushes in slow. The stretch is immediate and deep, the thick ridge of him forcing me open inch by careful inch. I can’t keep the sound in. My hands fist in the sheets as my body has to make room for him. He stops halfway, jaw tight, giving me time to adjust around the sheer size of his cock.

“You okay?”

“Yes. Don’t stop.”

He sinks the rest of the way in measured inches, eyes locked on mine, until he’s fully seated and we both go still. The fullness is so complete it steals the air from the room—every thick inch of him buried inside me, stretching me in a way no one else ever has. His forehead drops to mine.

“Fuck, Sophie.” His voice is wrecked.

“Yeah,” I manage.

He starts to move. Long, slow strokes that drag the heavy length of his cock against every sensitive place inside me. Myfingers find the silver in his hair and hold on. He’s so fucking good at this—better than the late-night fantasies I used to hate myself for having after that dance at my own wedding, the ones where I wondered what his hands would feel like, what his cock would feel like, whether a man like him would take his time or ruin me. He’s doing both.

“More,” I tell him. “Harder.”

His eyes darken. “Sure?”

“I’ve been thinking about this for five years, Grant. I can take it.”

Something shifts in him. The next thrust is sharper, deeper, the thick head of him punching the air from my lungs as the headboard knocks the wall. I cry out—loud, unrestrained—and he does it again, harder, driving that heavy cock into me exactly the way I asked.

“That?” he asks, voice rough against my ear.

“That, ah!” is all I get out before words leave me entirely.

His hand slides between us, two fingers finding my clit, circling with the same focused pressure he used earlier. The dual sensation—his thick cock filling me deep on every stroke, stretching me open, his fingers working me in tight, perfect circles—builds so fast it almost hurts. He watches my face the whole time, adjusting the angle of his hips when I gasp, pressing harder when my legs start to tremble. He’s reading me like he’s been thinking about this as long as I have, and the realization makes everything sharper.

“That’s it,” he murmurs. “Let me feel you come on my cock, baby girl.”

The orgasm hits hard and sudden, rolling up from where we’re joined and tearing through me. I clench down around the thick length of him, pulsing hard, saying his name loud enough to shame me later, back arching, nails digging into his shoulders.

He follows right after—rhythm breaking, a low broken groan against my neck as his cock throbs deep inside me, hot pulses of him spilling into me while my body keeps milking him through every aftershock. We hold on until there’s nothing left but the sound of us breathing and the quiet, heavy pulse of his cock still buried deep, twitching with the last of it.

We lie in my sheets breathing hard, tangled together, his heartbeat still hammering under my palm where it's flattened against his chest.

Grant's on his back. I'm on my side, head on his chest, listening to his heartbeat come down slow, then slower.

"Well," I say eventually, when I trust my voice again.

He huffs a laugh, rough at the edges. "Yeah."

"That was—"

"Better than I imagined."

I tilt my head up to look at him. "You imagined it?"

"For five years." His hand moves down my spine, slow and idle now, nothing urgent left in it. "Every time your name was in an email from Mom. Every time she mentioned you in a call. I thought about this. About exactly this."

The admission settles into me, warmer than the sex was, somehow. He's been carrying this as long as I have.

"Me too," I say, and mean it more than I've meant anything in longer than a year.

He goes quiet for a moment, fingers still tracing lazy patterns against my back. Then: "I should probably go. Mom will be home in an hour."

"Right. Yeah." But I don't want him to move. My apartment suddenly seems exactly the right size, and his arm around me feels like the only thing keeping the ceiling where it belongs.

His arm tightens around me. "Or I could stay a little longer."
