This actually is NOT a breeding. When he bottoms her out, he pushes against her back wall with constant unyielding pressure. It can be extremely painful, but an experienced bull knows just how hard to push. he pushes slowly, but firmly, deeper and deeper. he is essentially stretching every part of her. she is experiencing a strange mixture of pleasure and pain. she is in a state of continuous orgasm at this point. depending on his size, the orgasm can last several minutes. Once she is "resized" to accommodate him, she will never feel his again with this particular lover. Her hole is permanently deepened. the only way she ever feels this again is to seek ever larger cocks. each one will drill her deeper, but the sensation is rarely as intense, or lasts as long as her first. but her addiction is set in stone and she will spend the rest of her life seeking this feeling again.
