Story on this one. Several years ago. Awful recorder, upgraded since then.
Wife and friend, his first time anal with her, he wasn't expecting it because she had always said never, but drinking sometimes loosens inhibitions. She just lubed up and stuck it in, boy was he surprised. He had already cum twice so it took him a little while, I edited some from the beginning of the anal part, but there wasn't much going on then as far as sound.
She asks him if looks pretty a short way in, and then tries to talk dirty to get him to shoot it in her ass.
