"Thanks for the late night sex," Clary said, smiling, the moment I woke up that morning. Ever since Clary's boyfriend, Jace, died, she's been coming to my apartment at random moments to have sex. I sometimes I wonder if Clary misses she and Jace's sex, not him. I tried to tell her this isn't the way you get over a dead lover, but she insisted she's tried everything and this was the only way to get over Jace's death. I wonder if she'll be ever over because we've been having secret sex for two months now.

"Your welcome," I said and forced a smile. She put her head on my chest as she pulled the blankets closer around our naked bodies. Clary is beautiful, but she's like a sister to me. I had eyes on Isabelle Lightwood, but I hadn't asked her out because Clary is still getting over Jace.

"Clary?"

"Hmm?"

"Are you over Jace yet?" I asked tentatively.

Clary sucked in a breath. After a few minutes, she asked, "Why? Am I bad in bed?"

"No, I mean, yes I mean," I groaned, "it has nothing to do how good or bad you are in bed. I'm just asking."

"Liar," Clary said turning her head towards me, "Simon I've known you my whole life. I know there's a reason."

I sighed. It was time for the truth. "You see I've been wanting to ask Isabelle out for a while and plus I'm not comfortable with having sex with you. You're like my sister."

Clary cut me off, "You once had a crush on me."

I blushed. "Yeah, but now I'm over it. That was years ago anyway," I protested. "Also I don't think sex is the way to get over Jace."

"Jace wouldn't mind."

"Jace would be horrified that his innocent Clary has turned to someone who'd sleep with a guy to get over her dead lover. I bet he's cursing up in heaven at me for letting you sleep with me and I don't think God would be happy with Jace cursing," I said, adding a joke to the end.

Clary just commented, "Isabelle is doing that."

"I doubt she'd be having sex to get over her adopted brother's death," I said then paused. "Unless she and Jace had been having sex in secret."

"Simon."

"Look Fray," I began, "this isn't right."

"But Simon," she began, "this is the only way."

"Your only way is to have sex with someone? Okay then, that someone doesn't have to be me," I said getting out of bed. I started getting dressed.

"What?" Clary said shocked. She obviously expected me to give in like every time and maybe we'd have some morning sex.

"You heard me Fray. Go sleep with Alec or someone," I said, "but not me. Not anymore."

"Simon-"

I cut her off, "Go home Clary before your mum gets worried."

I know that's not like Clary to do that if Jace ever died, but lets say she's really depressed over him that she thinks sex is the only way to happiness. So, what will happen next? Will Clary get Simon to change his mind? Or will Simon ask Isabelle out? Stay tuned.
