Step-mom step-son cloakroom diaries - Part 2

Stepmom wants to do more shopping and step-son is still grounded so she has to drag him along with her back to the boutique. She tries on some new dresses and is about to put her clothes back on as she is only in bra and panties. She turns back around to find her step-son stroking his cock. He has been watching her and getting hard! She is embarrassed and knows that they cant come out of the cloakroom like this, so she tells him to take care of the issue. She pulls his pants down and tells him to make himself cum. He is having a hard time with her there just staring at it and wants some help, so he asks her to take her clothes all the way off. She just wants this to be over with so she does so for him. He keeps stroking his cock looking at his step-mothers body. He lets stepmom know that he is about to cum and she frantically grabs a tissue from her purse because she doesnt want to make a mess in the cloakroom.
