Wife cuckolds husband with a coworker while husband is there

[PeterEmery]

Wife is out with coworkers and texts (or calls) husband (or could be a boyfriend), inviting him out. She doesn't want the coworkers to know he is her husband/bf, so I think he was introduced as her gay roommate. As the evening progresses she ends up sleeping with one of the male coworkers, while he also ends up sleeping with another of her male coworkers.
