I love doing facesitting where I place my bottom firmly on your face, sit down nice and hard so you find it difficult to breath. If you try to wriggle about so you can breath I will just hold your head in place with my powerful thighs until I am good and ready to let you have some air.
How about me putting you in schoolgirl pins and then sitting on your face until you give in. Or I can be the boss whos ass you litterally have to kiss to keep your job.
You can have full weight facesitting or if you can't handle having my bottom in your face with my full weight pushing it down I can always ease up on you a little bit.
Any facesitting sessions I do is either with fullbacked panties or thong and tights.
