He nods. We’re both flushed and clumsy and out of breath, and I have no idea how to put on a condom. But I don’t want to say, Please, do it yourself, because my school didn’t really do the banana part of sex ed, and my mom put me on birth control on my third date with Oscar. Erik is staring eagerly at the foil in my hand, like it’s a gift of myrrh for the newborn king, and I think he’s more than a little into the idea of me doing this for him.

I grin. I have a Ph.D. in engineering: if I can build sophisticated machinery, I can figure out how to put on a damn condom. And there’s some trial and error, but Erik doesn’t seem to mind, spellbound by the way my small fingers work on him. When I’m done, his breathing is shorter. More stilted.

“Come back here.” He pulls me down to him.

“I— Do you want to be on top this time?”

“No.”

“Are you sure? I think I’m okay with—”

“Sadie. I want to fuck you, and I need you to like me fucking you. So you’re on top for now.”

I have no clue what the parameters for the magnum size are, but I do get why he needs it. I’m as relaxed and turned on as I’ve ever been, but it still takes a while to work him in, with small increments and false starts and lots of careful maneuvering. By the time he’s in as far as he’ll go, I’m sweating, and Erik is drenched. He smells delicious, like salt and soap and his intense skin. So I lick the place on his jaw where the drops have been collecting.

“Can you . . . ?” He arches experimentally into me. We both let out a groan.

“What do you want?”

“I want to feel your tits.”

“Oh.” I’d forgotten about my top. I straighten to take it off, which involves some twisting and grinding that has Erik gasping and trying to still my hips again. They’re not much, I almost warn him. But I remember something he said earlier. Uncanny combination of every single feature I’ve ever found attractive. “Did you mean it? When you said I’m your type, physically?”

His pupils track the progress of my hands, blown wide. “I noticed you.”

“Noticed me?” I undo the clasp of my bra. He twitches inside me. His jaw ticks with restraint.

“In the building. The lobby.” He closes his eyes. Then opens them. “Once in the elevator.”

I take off my bra, feeling stupid to have been worried. He’s staring at my body like it’s somewhere between holy and utterly, deliciously pornographic. “What did you notice?”

“Sadie.” His throat bobs. “A lot.”

“And . . .” I push down on my knees and circle my hips twice, working him a little deeper. A fraction of an inch, but the friction, the sense of fullness—my eyes roll back in my head. I didn’t know anything could be so far inside me and feel so good. Couldn’t have imagined. “And what did you think?”
