[f4m] corrupted into a cheating gang bang

I am dating your white step son/ brother someone who you are not a fan of and love tormenting so imagine your surprise when he lands a cheerleader as his gf this dumb bimbo, the story starts with me coming to see him but he wasn’t home as he was playing duengons and dragons but you and your friends were there, you invite me join your card game to kill time and I do not wanting to be a burden you start to get me drunk and high and start to play a combination of truth or dare or strip poker, you then suggest a fun little game where you and ur friends will place random objects in my mouth and if I guess right I get a point and if I don’t they get a point. This is a corrupting gang bang plot please feel free to ask any questions
