[FM] I cheated on my fiance during coffee shop opening

Throwaway,well for obvious reasons.So i am with my fiance for 13 years,we have hooked up at highschool and since then we have ‘mostly’ steady relationship.Before our relationship i was quite interested in sexual acts,i can’t say i was experienced since i was too young but i was eager to explore.I am a white 5’1 woman with pear shaped body and curly hair so even back then i could see that men having sexual fantasies revolving around me.My boyfriend on the other hand is all talk but no act when it comes down to sex.He is keeping the ‘main act’ for the marriage despite not being too religious and for 13 years all i had was foreplays.

So my boyfriend has a friend named Frank.Frank is like head of their friend group,they call him ‘the godfather’ for some reason but yeah basically he is the most respected member of their friend cycle.There has been many girls (some even in front of us) who confessed their love to Frank but he rejected almost all of them.As the matter of fact i have never seen Frank with long-term relationship and i’ve also known him since highschool.My boyfriend is blonde clean shaved guy and on the contrary Frank is bearded brunette guy (which i find really hot) so combined with his mysterious side,i have always felt attraction towards him but i held myself back.
