No, they do not. But there is always next time.

"Mom, I'm home!" You entered your apartment in a green jumpsuit. Ever since the day you successfully impregnated your own mother, you decided to participate in the U.A's entrance exam. And ever since then, you've been training both your quirk and yourself physically in order to get yourself ready for the entrance exam.

"Oh! Izuku! You're just in time! U.A has sent you a letter!" Inko walks out of the kitchen with a letter in her hands. And her body is still in a voluptuous shape with big breasts and thick legs as usual.

"Really?! That's great!" You said and then you opened the letter. After that the holographic form of All Might, the Number One hero of Japan appeared, and congratulated him for passing the exam and for be able to enter U.A as a student.

After that, you cannot help but smile and turn to look at your mother.

"Congratulations, Izuku!" Inko said as she walks toward you and hug you.

"So... what do we do to celebrate?" Inko asked and with that, you already have something in mind.

"Well... I know what we can do. How about... giving Kenta and Sara... playmates?" You asked and with that, your mother smirked, knowing what you meant.

"Speaking of Sara, she just breathes fire a few hours ago. As for Kenta, he starts to attract a number of small objects to him." Inko told you about the twins, the children who were born from the result of you successfully impregnated your own mother.

"That's great! So now, let's go have some... fun and... see if we can give them a little brother or sister." You said as you lead your mother to her bedroom and start another baby-making session with her.

As for the twins, they are sleeping peacefully in their bassinet in the living room. Having no idea, that their elder brother is about to impregnate their mother in an attempt to give them a little brother or sister.
