Tips for 🧍‍♀️🧍🧍‍♀️

So my fwb casually throws in wanting a 3 some and I’m lowkey down for it but I’ve never had sex w/ a female before but I am attracted to females. Wtf do I even do though? I don’t want it to be horrible (since I wouldn’t really know what I’m doing) 🥴

Any tips !!? Were y’all first 3some experiences bad,good,? Lol
