Husbands friend recognized me…what to do?

A really good friend of my husbands recognized me and I have no idea what to do. He has asked me not to say anything to my husband, which is probably for the best, but I’d feel guilty if I kept it from him. What should I do?!
Back the friend into a secluded spot/room. Do NOT allow him to say a word. As you are undoing his belt. let him know this goes on for as long as he can keep his mouth shut. By this point you should be on your knees, his cock in your hand as you tease the head. Only then should you engulf his shaft. Don’t be overly gentle. Make sure he knows you intend to swallow.
After he shoots his load, stand up, wipe your lips, tongue kiss him and remind him it only gets better if he keeps his mouth shut.
THEN go home and tell your husband.

Well said keep you mouth shut and keep mine full
