Hard facefucking and sperm cum in mouth

My girl is ideal slave, she ask me to fuck her in mouth.
I and my boyfriend were trying out bondage scenes as we were bored of normal sex every day. I’m tied completely and my eyes and hands too. He is being very rough and I like it that way. I like having rough sex. My mouth is wide opened using a bondage tool too. He is naked and his dick is hard and ready to insert into my mouth which is wide open to take his cock. He inserts his cock and it goes in easily as my mouth is wide open. This is so different than giving him a blow job. It is as difficult as my mouth is open continuously and can’t even close it for a while. He takes in pleasure as he can see me in pain and that gives him pleasure. I like it too as it is very kinky and tough. He is pushing his cock hard into my mouth and fucking me literally. It goes inside so deep and I can feel like I’m eating a dick. He holds my face and fucks me more hard until he feels like he is going to cum. He starts to moan a bit and cum’s all over my face and inside my mouth.
