19[F] i heard that if its between bestfriends it doesnt count as cheating

i am not sure if it’s slutty enough but someone told me to share it on here so here i am, hi :) me and my bestfriend have been teasing each other for a while now and lately it has started to be more than just teasing. today i was flirting with a guy and she was next to us and i think she got a bit jealous(she is the jealous type lol) and when we got home to get some work done(we were on the bed) i caught her checking my breasts and after a minute she started to unbotton my shirt and making out and uhh it was better than anything. she has a boyfriend and she thinks its fun to touch me under the table when he is just in front of us and i cant say i tried to stop her so…idk who is the slutty one
