I don't know about a massive thrill. . but last week I convinced my painfully shy wife to go to a lingerie/toy shop. We browsed for a while before we got over to the lingerie section. She found four items she liked. A couple of corsets in different sizes and two teddies.
There were two clerks working, both girls. One approached us and said my wife could only take two at a time into the dressing room. The clerk also had to unhook a plastic antitheft device up at the counter, which took a while. We went back to the dressing room and my wife insisted I come in to help her with the corset. I told her I didn't think two were allowed in at the same time, thinking of the nasty stuff the clerks probably didn't want going on in there. My wife insisted so I went in and helped.
Neither corset really fit (but I think it was user error, neither one of us having much experience). So, tits out, my wife asked me if I could take the corsets back and pick up the teddies. I told her it might be a bit since the first time took a while to undo the antitheft thingies.
I threw wide the door as I left, and my wife hissed and shrank into the corner like a vampire at light.
She pulled the door shut behind me and I walked up to the counter.
The first clerk who had helped us was across the store helping someone else. The second clerk was behind the counter. She was short, nice figure, and smile, had a skullcap of platinum blonde hair. I walked up and put the corsets on the counter. She asked if they fit and I said no.
Without asking she came around from behind the counter with the two teddies. The other clerk had apparently already got the antitheft things off.
Total time I was gone from the dressing room, 20 seconds maximum.
As the clerk walked to the dressing room to give them to my wife, I realized what was about to happen and started to say something. . .then just bit my tongue.
The clerk knocked on the door, it opened, and I heard an "eek!"
The clerk handed the teddies through the door and walked back to me with a proverbial shit-eating grin on her face. I gave her a thumbs up.
I later caught shit from the wife - she'd gone down to just panties in my absence and the clerk got the whole view since my wife thought it was me at the door.
Totally not planned, fun nontheless.
