Bruhdah, foreplay relaxes the muscle and makes it safer and easier for sex.
Like how a woman can be so tight means they are not aroused.
But for a bottom it shall be the ass that's to warm up and spread it's muscle instead of clenching.
And for loosening the ass Something like a lubricant will be needed.
I bet the top would like to do the foreplay, coz seeing the bottom being pleasured, arouses him.
what's foreplay²?!?! you're getting fucked anyway!
