“Wait,” I say, reaching for her wrist and grabbing the jar from her other hand.

She looks up at me, confusion clouding her eyes.

“Let me,” I say in a hoarse voice. “Remember?”

She gulps nervously, nodding her head, blinking up at me.

“Lie back.”

I really cannot believe I spent almost an hour enduring my little sister’s harassment only to take this dress off damn near as soon as I get here. Before Darren even got to see it! That’s what I get for trying to be seductive and sultry instead of shamelessly horny.

The lesson here is to always be myself.

And there’s nothing wrong with undressing in front of Nadia. Nothing at all.

She’s lying flat on her back, staring at the ceiling, her chest and stomach moving quickly, her breath coming hard and fast. She turns toward me when the sound of my zipper rips into the quiet room. She watches me with wide, hungry eyes as I shimmy out of this dress and push it down my body. She whimpers at the first glimpse of my strapless white lace bra, my ribs, my stomach and the gold charm in my belly button, and the lace underwear I slipped on, hoping to feel her pull it over my hips.

Nadia licks her lips. “You like lace?” she asks.

“Yes,” I nod, reaching behind my back and undoing my bra.

I watch Nadia watching me and go slow so we can both appreciate the building tension. She gasps when my bra loosens and smiles when I hold it to my chest, teasing her for a little bit longer.

“Is there anything you don’t want to do tonight?” I ask her.

Her eyes fly to mine. Technically, we’ve already had this conversation before; we’ve been having it since the night we first connected on InfiniThree. But it can’t hurt to have it again.

My last ex said I was too much, too horny, too excited. I don’t know that there is such a thing — I certainly didn’t think so when I dumped her — but for some reason, her words come back to me in this moment; a small frisson of doubt runs up my spine.

I worry for a second that one of the possibilities for tonight is that this will all come to an end. That Nadia will realize when we’re all here together that this is too much. That it was one thing to watch me sucking her husband off on video or to let me join in as one more hand in the movie theater while we fulfilled one of her fantasies, but this — the three of us — is too much. That letting me into their adorable, perfect, suburban life won’t actually work.
