The Beginning of the End

[youknowwho]

I was surrounded by a few mates, drinking more than necessary considering the party had just started. My eyes scan the room, hoping to recognise some faces in the crowd of strangers around me as the music pulsed through my body. But then, my heart stops. It was you. I hadn't seen you since we'd split but as I notice his arm around your waist, I can tell you're not here alone

First or third person is fine!
I'm dominant so looking for submissive or possibly switch
I prefer Adv lit - Novella please
Any other questions - just ask!
