I'm a 63 year old enthusiast. I love variety so I rarely see a provider twice unless she is exceptional. I do remember the rowdy sexual escapades of my college years that often meant Sally was leaving just as Gina was arriving. Back-to-Back encounters.
In my decade watching ads I have never seen two providers offer a tag team 2 hour buffet. What would be my preference would be an in call at a 4* hotel like the Crown Plaza where both providers are punctual. First hour with provider #1 and provider #2 arrives to start hour two. A twist would be 30 minutes solo with provider #1, 30 minutes in doubles with both #1 & #2, then 30 minutes solo with #2.
Any others think providers would be interested in this or as a rule providers can't manage time we'll enough to be punctual for a single session let alone something this logistical?
