My husband kept looking at me in disbelief, so I got on all fours on the bed, so he could see my availability. To make it even clearer to him, I spread my buttocks, showing him the way to follow. Mike knelt behind me and began caressing my ass with both his hands and his erect penis. I told him it was ready and he held it, carefully placing the tip into the hole. He put it in me very gently, held onto my hips with both hands and began to push subtly. I couldn't deny that it hurt me, but there was something so morbid about what was happening that it made up for the pain. He slowly made his way until he entered as much as my tight anus allowed him. Although I avoided screaming at all times, my husband knew me well enough to know that I was hurting, so he accompanied everything with caresses and nice words to calm me down. It made me happy to know that I was fulfilling a fantasy.
