Isabella and the delivery man

Isabella was having sex with the delivery man she had been arguing with before. He had her bent over the stack of boxes he delivered, fucking her doggy style. Her skirt was down at her ankles and his khaki shorts and boxers were on the floor behind him. She was squeezing her own tits through her blouse. He had his hands on her hips and was thrusting in and out of her pussy hard and fast.

"Are you going to sign for those boxes now?" he demanded.

"Yes! Yes! Fuck, Yes!" she gasped in response.

Neither of them noticed me standing there. I was tempted to stay there and continue watching, but I knew I should go back to the counter.
