Mega Public**Changing room blowjob-Wiped me out by the shop assistant

I went shopping with my mate and quickly found a couple of nice pieces....then my mate suddenly had this perverse idea and offered to pay for the clothes, but only if I opened my mouth wide in the changing room, showed my plump tits and swallowed his cum....it's blatant how he takes advantage of me....he knew exactly that my pocket money was already used up....man fuck I had to take him up on his offer....but there's always a shop assistant in the changing rooms....will she notice? Or is she busy with other customers??? It went straight to the point tits out and mouth open hihi was already cool to blow so publicly and then suddenly this announcement? We were swindled ???? I want to do it outdoors more often again :) Please rate and leave me a commi!!! Kisses your Lisa
