I had a threesome with a guy and another girl a few months back. First time with a girl, nervous af. She takes my shirt off and starts rubbing her fingertips on my nipples. For me this is fucking torture. Probably the most ticklish spot on my body. I tried so hard to keep from giggling but failed miserably. When she noticed this she exploited it, teasing me about how my nipples were so sensitive. The guy we were with commented on it saying "she's ticklish" to the girl. They spent the rest of the time talking about me like I wasn't even there, making comments about how wet I was and stuff like that, which was a bit humiliating but hot. She even started tickling me on the lower part of my ass and inner thighs, telling the guy to take notes.
I think about this experience a lot.
