What Would You Do?

Hypothetically Speaking 

You met this person through a friend. You have intercourse with this individual, although this individual is MARRIED. The intercourse is horrible and you two never speak on it again. The two of you remain cordial simply because you have mutual friends. The sex was whack so being in an intimate situation is no longer an option. It was just sex with no strings attached.

Before having sex with your married friend, you get approached numerous times by their friend. They know nothing about your secret rendezvous. They actually approached you before you had any sexual endeavors with the married friend. They actually want to talk and get to know you. Rather than solely base your relationship off of sex..

My question to you is would you "talk" to them or is this situation too messy?
