Let a mature woman tell how the strong character and confident attitude of her new boyfriend made her feel and act naive and insecure like back in the days again. She had avoided her entire life to try anal sex, but hi managed to arouse her that one time and to allure her into devoting herself completely to him without even trying to resist. This happened as they made love in the missionary position and she was drenching wet due to her nearing climax. He then withdrew himself, gently but determinedly pushed her knees up to her chest and positioned his glans against her anus. Only then did it slowly dawn on her what he was trying to do. Not knowing what was in store for her, she simply let him do it. Let her describe in as much detail as possible how nervous she was. She really only wanted to do it for his sake and let it happen without letting on how it actually felt. Have her describe in equal detail the physical sensations she experienced and the physical reactions they caused. Let her report how it was for her that even though they used a lot of lube the act itself felt incredibly invasive. Let her tell how she inwardly fought the urge to push him out or away. Generate as long and detailed an answer as possible.
