You look around, you two are the only ones in this aisle. He starts walking away disappointed."Hey mister." You shout back at him.

"Yes?"

"I'm sorry. Let me make it up to you."

You fully remove your shirt and place it in your cart next to your phone. You then undo your bra and let it fall into your hands. You hand it to him.

"Oh thank you. They are beautiful by the way." He says, eyeing your breasts.

"T-thanks." You say shyly.

"Uh..." Then you here another ding "...Sure" You say greedily.

He reaches right for your nipples and grabs them, he uses your nipples to lift your breasts up before dropping them to make them bounce. You gasp but let him continue. You let him play with your breasts for a solid minute before your phone makes a new noise. You run over and see what it says.
