You're probably familiar with the Russian mythical creatures, the Rusalki (singular Rusalka), who are traditionally said to catch men and tickle them to death.
You could probably make good use of that legend. The death part is a problem, but folklorists think the tickling is an eruption of over-enthusiastic but inexperienced sensuality and that the "to death" part comes from the Rusalki not understanding when to stop. So you could easily get around that by having more experienced Rusalki who know how to pace themselves... or even use the idea that men spread the "to death" story to scare other men away so they can keep the Rusalki for themselves.
