Stepson buys stepmom a new dress. She was surprised by his choice of clothing for her but she agrees to try it on. He wasn't expecting her to undress in front of him but she begins to try on the dress with the bra she was already wearing but apparently that one will now work for this dress. She begins to take off her bra and put on another one that she thinks might suit the dress better. He's amazed at the size of her boobs once they drop out of her bra. She loves the dress, it makes her feel sexy and stepson is getting hard just watching her.
