“Remember that time in middle school…” she sighed softly into his ear as his cock slid up inside of her and she settled onto his lap “… when mom and dad almost walked into your room on us?”
His hips wiggled as he felt her warm snug pussy glide down to the base of his shaft. ”Yeah.” he whispered.
“Remember how you had to pull out before you could cum?” she asked softly, nibbling on his ear as she moved her hips in a circle on his lap, twisting his cock around inside of her.
“Yeah.” he gasped at the feeling of the head of his dick rubbing on the roof of his sister’s box.
“We’re alone. No one is going to walk in today.” she whispered every so quietly as she leaned in to kiss him.
