Mijn vriendin gedraagt zich niet geïnteresseerd in mijn oudere stiefbroer, maar spuit eindelijk als Niagara Falls

I revealed a secret to my girlfriend that I know about her fck affair with my stepbrother and she promised me to stop it and next time don't do it anymore. step But this secretly recorded video I got now is something strange and I don't know should I be happy or sad. It's more like sick I would say...
