F25 – He fucked me in the changing room while my boyfriend waited outside

My boyfriend and I were shopping for his birthday present. I tried on a tight dress and the fitting room attendant (tall, quiet, mid-30s) kept “checking” if I needed help. Third time he came in he locked the door, pushed me against the mirror, yanked my panties down and slid in raw. I had to stay quiet while he pounded me hard enough that the mirror rattled. He came inside me, wiped me with a tissue, and left. I walked out to my boyfriend still holding the same shirt. Still had his cum dripping down my thigh on the drive home.​
