Ignore.

Beth got undressed, pulled on some shorts and a t-shirt, and got straight into bed after brushing her teeth. She was exhausted from her evening fuck session, the kind of deep, in the bones weariness that comes from getting fucked to satisfaction. As she teetered on the edge of consciousness, Brian's body slid up behind hers in bed. She could feel his cock against her ass: he seemed to be naked.
"Hey... I missed you tonight... do you want to..." he started kissing her shoulder.
Beth very much did not want to. Now you're getting all sexual? Now you want to fuck me? She was annoyed.
"No, baby. I'm tired."
"Oh... ok..." he seemed disappointed, as if he expected her to leap at the chance. "..goodnight, then?"
"Yeah, baby." she didn't really care if he was suspicious. She drifted away into dreams of more good dick.
