" She catches me off guard when she throws her arms around my neck and hugs me. I groan softly when I register the smell of her skin. Liz had been a big believer in pheromones and though her scent hadn't done much for me, I have a feeling she wasn't all that drawn to mine either. I don't know if I buy into that kind of thing, but whatever the cause, catching a whiff of Annika has always had a strong effect on me. I can't explain what she smells like because it's indescribable. On the rare occasion when she wasn't spending the night in my bed at my college department, I would switch pillows and lay my head on hers. The odd thing is that Annika couldn't stand perfume and only used unscented soap, so whatever I detected had to be coming straight from inside her.
This obviously isn't our first date, and following some sort of protocol seems arbitrary and juvenile. I mean, we've seen each other naked. I know the sounds she makes when she's turned on. There aren't many places on her body that my fingers and mouth haven't explained.
I hug her back and though it's hard to let her go at the end, I do. "
