Well so my gf fucking behind my back has been going on for a bit now and i am used to her fucking her roommate.
But she topped everything this week.
So what happened was that she went to a party with a few friends and that said roommate.
They were having fun with lots of people but when the party was near over most guys and girls left and only few were still there.
One of them my gf and her roommate + his friends.
They decided to play truth or dare and this is where it began. All of the girls were singles, some guys had fwbs and she was the only one with a real relationship.
