I don't know if you're referring to my comment from a while back or not (as I was one who mentioned "cheating" and "secrecy") but I was specifically referring to with the MC's consent. As in after Tara sends the pic of Laura kissing Nathan, the MC and Laura decide to maneuver her to send pics of her doing stuff "behind his back." She doesn't mention it, but the MC still gets the photos, and they pretend like she's cheating. Just a little roleplay to spice things up in a different way. Again, orchestrated together and with consent.
