Blindfold
Rose wakes to the familiar sound of someone trying and failing to come to bed very quietly. “Doctor? S'that you?”
“Nope.” He snuggles up behind her.
She giggles. “No?”
“No, not the Doctor.” He kisses her shoulder. “Just a random naked man.”
She reaches back to stroke him. “Mmm. Well, whoever you are, you’re very hard.” She pushes him onto his back and climbs over him. “You better shag me before the Doctor gets home.”
“Rose!” he squeaks, indignant, then, “oh.”
“S’okay. I knew it was you,” she whispers, rocking gently against him.
“You did?”
“I could pick you out blindfolded in a naked lineup.”
“Impressive.”
“I’ve got all kinds of tricks up my sleeve.” She takes him deeper.
“Show me?” he gasps.
“Oh, I’m about to.”
