Brief F/M roommate tickle

[Ticklishfeet76]

I wasn’t a participant in this story just an observer. One day while I was eating lunch my roommate was talking with his gf on the couch as they were drinking wine. At some point she must have tickled him because he flinched and asked if she had tickled him. I had told him to tickle her back, I would’ve helped him but I was eating lol. His gf panicked and protested so unfortunately I don’t think he got revenge. I’m not sure if she was panicking because she was ticklish or if she was worried she’d spill her drink lol. Think later they were talking and she had her bare foot hanging over the couch arm with her sole facing up. I walked by and strongly debated tickling her feet but decided to pass on doing that.
