I would do 3 or more of the following things to your Japanese wife. I do many of these things nearly everyday with many cheating Japanese wives here in Japan. It's very commonplace for a dominant bull such as myself. Let me know what you think:
1. Tying her up with rope and hanging her from the ceiling as she takes it from all angles
2. Harking gobs of spit in her face, mouth, and hair before, during, and after Mach-5 Fellatio (Saliva Beauty Masking)
3. Mach-3 - Mach-5 level fellatio (you know, the type where you can't see anything but the afterimage of her head and hair as she chokes violently on a 8'1/2 inch cuntbuster).
5. Shitter splitting anal in all angles, with a healthy helping of ATM intermittently
6. Cum on her wedding ring, while she holds a picture of herself, her husband, and possibly other family members of which I also dump semen on, and then take a picture of myself for my personal collections.
7. Shoving her filthy panties into her mouth and forcing her to wear it around her neck as a leash, or wrapped around her head/nose as a stinky reminder of who and what she really is
8. Handcuffing her to her heels (4-way handcuffs) and providing relentless mach-4 gagging & spit-face training as she lies belly-down on a flat surface.
9. Clipping her clitorus, nipples, and nose with clothing clips while destroying her pussy and asshole endlessly in unison.
