I [M] fucked a milf [F] inside her clothing shop

There is a small clothing shop, a couple of blocks away from my house. I go there preety often. The shop’s owner is a smokin’ 37 year old milf with big tits and a fat ass. We already knew each other because I visit the shop often. She usually dresses really young for her age. This time she wore a pair of see-through leggings and a red thong which was very visible. I looked around for a couple of minutes when she approaches me:

– Hey there, how you doing, can I help you?
– Yeah I’m good, I’m looking for these exact same pants but a smaller size if you have.
– Sure, let me check.

She bends over to look for another pair. Her ass was right in front of me. The thing and the ass crack was clearly visible. She accidentally rubbed her ass against my leg.

– I found a pair. You should go and try it
– Great. Thanks!

After I tried on the pants:

– So, are they good.
– I’m afraid they are a little tight on me. Don’t you have another pair?
– I’m afraid I dont.
