I Wasn’t Watching Dan
Watching them had become routine in the worst way. The accident excuse had died weeks ago.
Sometimes I stayed away on purpose. Sometimes I heard Lillian moan and found myself halfway down the hall before I had finished inventing a reason.
The jealousy still showed up. It was just no longer the only reason I listened.
I told myself I wanted to know what Dan saw in her. That excuse was getting flimsy too.
Another meeting reminder popped up on my laptop. Apparently getting fired was tomorrow-Mia’s problem.
I closed it and stood up.
Lillian’s door was open.
Dan was on his back. Lillian straddled him, riding him slowly, her hands braced on his chest. She was completely naked, head tilted back slightly, lips parted. The afternoon light through the window caught the sweat across her chest and stomach.
I stayed in the doorway longer than I needed to.
I had seen them together before. But my eyes followed Lillian instead: the movement of her breasts, her stomach tightening as she rolled her hips, her mouth opening every time she sank down on him.
Studying the competition. Sure. Very academic.
I stepped into the room.
Neither of them stopped. Dan glanced at me with a lazy smile, but his hands stayed on Lillian’s hips.
Lillian’s eyes opened and found mine. She paused for half a beat, then arched her back a little more.
The little exhibitionist.
I sat on the edge of the bed and touched her side, just above her hip. Her skin was warm. Her breath caught.
That little moan went directly between my legs.
I slid my hand higher and cupped one of her breasts, brushing my thumb across her nipple. She moaned again, so apparently I was not completely fucking it up.
I had no idea what the fuck I was doing.
I pinched too hard. Lin flinched, and I immediately flattened my palm over the spot like that had been the plan.
Her hand closed around my wrist and moved me slightly higher.
Oh.
That worked.
Dan watched us with the pleased, lazy expression of a man convinced this was somehow about him.
I watched Lillian’s face instead: every caught breath, every small change when my hand moved.
