Let's see, for 900 bucks...
Considerring:
Blowjob discounted `husband` rate @ $15/pop, drops $1 per year with age over 40 until reaching $1 where it stays for life.
Unexpected sex @ husband rates is around 35/pop.
I value that ring at 20 bjs and 17 fucks on top of the usual woman rate of 5/week over a 12 month period.
Hope it's worth it!
Does look very nice though!
