This is almost exactly how I found out my ex-wife was cheating. She bought a ticket to a concert and then freaked out when I bought one too. Why wouldn't I want to go to a concert with my wife? She said it was just going to be a thing with her friends from work. When we arrived there was exactly one friend from work. A guy friend.
thrust distance per coitus session: 13 cm x 300 thrusts x 2 (accounting for insertion & removal) = 78 m
coitus sessions to accumulate 5 km of thrusts: 5 km / 78 m = 64.1 -> 64 sessions of coitus
So OPâs wife would have to fuck 64 times to accumulate 5 km of cock. Even with amazing refractory periods, thatâs still a minimum of 32 guys running a train on her.
Edit: working through this reminded me of that episode of HBOâs Silicon Valley where they started talking about handjobs and hotswapping dicks and hit on middle out compression.
Sir I think you are forgetting that you do not pull the pens completely out with every thrust unless you want to snap it off by accident. I think a 1.25 multiplier to your calculation is therefore necessary.
Why would OP's wife not just sign herself up if she was going to run? Or realise something was off when her partner told her that they'd done it for her. "Hello, I'd like to sign my wife up for this run. Oh no, I won't be participating myself." Feels kind of weird. But this a 4chan post so can't possibly be fake or gay.
