I know with my fuckbuddy, the hottest thing that I can do during sex, is when I try to "physically resist" and say "NO" to him or tell him to "STOP" when he takes me from behind with brute physical force.
I know it simulates his "rape fantasy" for him and makes him even more horny, hard and fuel his ability to cum and orgasm. I geuinely love trying to stop his advances, because he gets so animalistic, aggressive and strong with me, that he overpowers me, its a huge turn to be desired and lusted in this manner. Not to mention the bruise marks he leaves on me.
The irony is that he is like 6ft2 and 130kgs and I am 60kg and 5ft5, so he will always win anytime we wrestle and I try to prevent him.
At the end of the day,we are both adults, consenting and have a safe word.
Post orgasm, he is so sweet, affectionate and caring as he always checks on me to make sure he didnt cross any lines or boundaries, so he knows for next time. Even if he did, I wouldnt tell him, we have too much fun and pleasure. lol.
