Get a cheap DD. Great for fun = sucks for daily = compact, noisy, direct and raw.
Even sex can be boring if you let the daily grind get to it. Make a special date. Let her do what she does best. The Z likes it rough, thrown around, on top....not the same 30 sec missionary style that daily commutes represent.
The night before the date (weekend morning drive, autox, HPDE):
- Feed her a nice meal.
- Good bubble bath and feel her curves
- Take naughty pics.
- Think how great it'll look when you two are having fun
- Take naughty video
