Yes, he did.

"AH! AH! AH! AH! AH! AAH!" You and your mother screamed out very loud as you're pumping her in and out in her pussy with hot massive erected cock while your right hand grabbed and ravaging her left boob savagely!

And this is happening in your mother's bedroom! On your mother's bed! And it has been going on for two hours!

"Oh! Izuku! OOH!" Your mother said as you are slamming your hot rod into her like your life depended on it.

"Oh! Mom! You... you're so good! So soft! So sexy! And so tight!" You said as you're hitting your mother's womb with your manhood.

"Oh! Faster! Harder! Do both, honey!" Inko said as her pussy is being slammed by her son's massive cannon while her big breasts are bouncing around nonstop.

Inside her body, your penis is hitting the entrance of her womb again and again. Suddenly, your penis is slamming harder and faster against the womb's entrance as strong as a battering ram!

As this is happening, you're also kissing your mother while also massaging her right breast with your left hand as well!

After many more thrusts for another 30 minutes, you and your mother reached the climaxes! You unleashed all of your sperms inside your mother's womb!

Inside Inko's womb, millions upon millions of her son's sperms are swimming around, blindly searching for the eggs to fertilize.

Eventually, many of them reached Inko's two eggs and two of them managed to successfully penetrated into the eggs, thus beginning the fertilization.

Whether or not one of them will be born with your quirk or not is unknown at the moment. But what that can be confirmed at the moment is that Inko Midoriya has been impregnated by nobody else but her own son, you, Izuku Midoriya.
