I had a pal who got a couple from a lad at work...
He wanted to give one a wirl with hot chix but wanted to know what it would be like before hand..
So he had half one evening, raging hard on for hours was on 6/2 shift next morning still had it up, got to work and it was still going he had to crack one off in the locker room.. powerful stuff he reconed it was top class when on the job you could go for hours even if you jizzed its once in a blue moon stuff apparently it takes it out of you...
