Can you do the pyramid challenge for a week?
It's Day 8, congratulations loser boy.
Hopefully your dick recovers, it might never get quite as hard as it used to. I wonder if you can strain a muscle in your cock? And if you do, how would your little nub ever recover from it?
Let's see your measuring cup stroke-meister!
There are 10+8+7+6+5+4+3 = 43 loads of cum in there. Although considering you barely got a single drop to come out during your last few orgasms yesterday, it may as well be only 20 loads of spewage!
If you have less than 40ml of semen in that cup, YOU'VE STILL FAILED THE CHALLENGE!
But if you have more than 40ml of semen in that cup, then great job! You truly are a stoker champion. You've just about killed your dick to prove it, but it was worth it wasn't it!
