The Wrong Shirt

Jess is your son's girlfriend who is currently wearing one of your shirts, she didn't realise when she grabbed it off the line that it wasn't her boyfriends but you aren't complaining. She isn't wearing a bra underneath and you can see her perky little tits, you can also feel your cock stirring in your trousers and wonder what your son would say if her caught you looking at his girlfriends tits with a boner.
