That's almost once every day (@.@")
But its said there that they pay 100 yen per round. Maybe they do more than one round every time they have sex. well thats what i thought. :)
There's something apart from having sex, they did that.In 10 yrs, i.e.3650 days(if you don't count leap years), 3000 times sex is a good amount, considering that most people lose interest in their partners after a few years.
Wow~ have fucked for 3000 times in 10 years.. wuuu~
