Even though it's wrong, he accepts!

Touched by your gesture, your dad nods through his tears, raising his head so that his face was opposite yours, you kissed your dad right on the lips. Blushing, he returns the kiss and soon, you two are deeply making out. After a few more minutes, you broke the kiss, eager to get underway with your dad's breeding.

Leading him to his room, you tell him to strip off and lie on his back with a pillow underneath his back. Meanwhile, you head to your room and grab some lube that contained a mild analgesic to numb the pain, you also quickly swallow a Viagra so that you had the best possible chance of getting your dad knocked up.

Once you enter your dad's room, you smile as you see that he did exactly as you asked. Stepping closer, you spread some of the lube onto your cock, with a fair bit more going onto and inside your dad's hole. As soon as you felt that both your dad's asshole and your cock were ready, you got close enough that you had to pull your dad towards the edge of the bed for his hole to be at the right height, making sure he kept the pillow underneath him, you held your cock at the entrance to his hole.
