Surprisingly, yes. A woman I met at a gathering was rather tipsy and quite flirty. She "started it" by poking and taunting me which turned into me tickling her. As soon as I started tickling her she sort of fell across my lap face down. I tickled her sides and underarm and all she did was squirm around laughing like crazy. She didn't try to stop me or say anything about stopping. I paused a few times not wanting to overdo it but she just stayed put while breathing hard. Once, she turned her head and looked up at me which was my indication to tickle her more. That lasted for an undermined time but was a nice surprise with, literally, a stranger.
