Party for three

I ring the doorbell. The twins answer the door, smiling nervously. I notice they are dressed in identical school uniforms. They both have their long blonde hair tied back, one in a ponytail and the other on either side of her head.

"Hey, girls, what's up?" I say as they stand aside to let me in. I notice no one else seems to be home. There is no music on or food or drinks laid out. It looks like no company is expected at all. "Where's everybody else?"

"Um, it's just the three of us," one admits.

"Oh yeah, what happened to the party?"

The twins share a mischevious smile. The other responds, "Well, we thought it could be a party for just the three of us." She runs a finger down my chest and smiles up at me innocently.
