So I showed my new girlfriend some wrestling pics and she said it would be fun to roleplay, now she is ,6 ft tall and 350lbs and I'm 5-9 220 , so we started on the floor she was wearing leggings and a sports bra and I was wearing just shorts it didn't take her but seconds to get on top of me and pin me a few times , I said good thing you don't know how to smother and she slide up sitting on my face, I turned my head a few times but she grabbed me by the hair lifted my head and slide one leg under my head and it was over , I couldn't escape or breath and I tapped a few times before she released me and asked me if I liked that and I said wow when you wrapped your legs I was at your mercy and couldn't do anything she laughed and now that's her favorite position cause she can ride my face and get off while I struggle for air , I can't even go down on her without her locking her legs in a figure four and smothering me and if I don't go down she will force me between her huge legs and smother me or use my face for her pleasure, so the other day she comes home with her sister and out of no where she just pins me to the floor and folds her legs under my head and smotherd me in front of hee sister, her sister is now texting me and asking me questions and wants me to show her how to apply that hold , do i tell my girlfriend she is asking , i told her no and now she is threatening me that she is gonna tell her sister I'm flirting with her and if she does my girlfriend might just sufficate me cause she said if she ever caught me cheating she would smother me to death , what do i do
