Liam didn't know what is going inside his mother's and Celestia's head, at this moment his head is like it's floating, whenever he move his hips and push his dick inside his mother's pussy, he felt a different sensation feeling that he couldn't tell.
Not to mention that her pussy and especially her womb which is quite narrow cause his thick dick and it seems to squeeze his dick a completely but it isn't painful.
It's very comfortable feeling, feeling the tightness as if it's virgin pussy, he couldn't help but amaze and at the same feels really good, whenever he moves his hips, he could feel his mother body shaking with pleasure.
Especially those dirty words that seems to come out from her mouth automatically aroused his soul lust.
His hips couldn't help but move fastly and he also started saying "Mom, you are so beautiful. Today I will pregnant you and make you bear my child."
