I got to know H-cup Kahori, who loves sex parties, and she asked me to help her cuckold her husband. I swapped husbands with I-cup Nana, a married couple who are friends, and started cuckolding her! He kissed her in front of her wife, and she got excited and jealous when she saw that her husband's dick was harder than usual, so we started a reverse threesome! The two of them made use of their voluptuous bodies to give her a titty fuck, and with a close mutual piston-like thrust, the masochistic husband ended up ejaculating inside the pussy of another woman.
