Ignore the sound and keep going

As you kiss Loretta's breast, you hear the noise again, what you think is a pebble thrown against the bedroom window. You don't think anything of it and continue to suck on her nipple.

Pushing her long, slim legs apart with your hands, you climb on top of Loretta again. "I can't get enough of you, Loretta."

"Yes, John. I need you inside me," Loretta pleads, staring up at you.

Sliding in her again, you pound her into the mattress, kissing her to muffle her outbursts. She wraps her legs around your waist, squeezing you with her thighs.

Your hard-on twitches just as you hear the stairs creaking.
