Penelope groaned and tilted her neck, giving Derek more access.
"You're…you're going to give me a hickey," she gasped as his teeth sunk into her neck.
"Do you mind?" he whispered between kisses.
"Well….well…Hotch might see and everyone else."
Derek's lips turned up in a smile she could feel, even if she couldn't see, "Everyone would know….even Kevin."
Penelope blushed, "Derek, you know I don't…"
"I know you don't sweetheart, but that doesn't mean I mind everyone knowing that you are very, very taken."
She sighed happily as he began sucking on her skin, now determined to leave a mark, "Well, okay, but can I give you one next."
He pulled back to smirk, "Baby girl, you can mark me anywhere you want."
