[MKMP-732] My father, a sex offender, came home after prison release. After more than ten years, my boyish appearance worried him into marking my body with female pleasures.

The final minutes of the film truly capture the reason why we cherish the women in our families.
I imagine Nakata has been using her for a week straight, without any cleanup, as implied by tissue covering the floor. If he needs to rest, he rests on top of her with his cock still deep inside, resuming intercourse once he recharges.
Meanwhile, Ena is filled with old cum, maintaining her position as a literal fleshlight.
A beautiful representation of traditional values.

Ena barely does any movies these days and they pair her with this lazy fat fuck. If public demands she fuck some old guys, then let it be Toru Ozawa or Tomohiro Abe. Atleast they have the stamina and actually fuck the girls.
