How often do you do otc with a cf/atf?

1) As often as time, money, and schedules permit.

2) Usually, though I won’t spend as much.

I did do OTC with my ATF Stripper every weekend Saturday afternoon/overnight for about two and a half years, until she retired (sent me a good by text thanking me)
I didn’t see her ITC during that time, because the OTC was the best GFE and ITC couldn’t compete.
