I have a HW now that can only cum with a larger cock in her ass. So I come over while they are both asleep, (I have a key and their dogs know me) I wake her up and mount her. Hubby usually lays and watches or goes to work. She insists on me going deep and ejaculating while she masturbates. I feel her contractions in her rectum when she cums and she squirts a little. According to them, I'm the only one that can go deep and bring her to orgasm....and she cums HARD!! Anal hits spots and nerves that vaginal sex cannot. Work into it. She will find her orgasms are REALLY strong with a large bull dick in her ass.
