It gets better once you get past the pain. But you have to stay still and take it. If you push back it gets better faster. Trust me I've done it and I love it. You will too.
I may be wrong because I have no experience in such matters. I think if you like a guy and you want to have sex with him, then you shouldn't run away from him. Moreover, the domin its time on you, on preparation, on opening the ass, it also takes a lot of energy for sex, and you, as the bottom, can't do just two things: first, spread your legs, and secondly, as a thank you, expose your ass, relax your buttocks, and give your ass to be torn apart. Well, it hurts a little, and that's okay, and anyway, I think someone who's bottom should be able to enjoy the pain.
So hot. I LOVE when a top is presistent and keeps going even if I'm trying to pull away or push him away. Don't let me stop you from getting your nut... I agreed to this. Hold me down and go harder. Even if it hurts I'll be grateful.
