Shusaku's better

Miyu: (teasing) your dad's better! Compared to him you're just a little boy trying to be a man!

Takeru: (feeling humiliated) damn you!

Miyu: (enjoying her stepson's jealousy) your dad is a real man he can fuck me all night! But you're already close to cumming aren't you??

Miyu grinds herself on Takeru's cock increasing his pleasure and bringing him closer to climax.

Takeru: (involuntarily) ahh!

Miyu: (grins understanding how close Takeru's to climax) I can never be satisfied by your little boy cock Takeru-kun! Not after I've been with a real man like Shusaku!

Takeru: (feeling his cock being squeezed by her tight wet cunt) ahh!

Miyu: (placatingly) but it's ok. I'll let you shoot your cum inside my pussy just this once!

Takeru feels very humiliated but he can't stop himself from cumming. Miyu giggles at how east it was to tease him and make him mad.

Miyu: (smiles taking her stepson's spent cock between her thumb and index finger) like I said just a little boy trying to be a man!
