WTF
 

I saw this and thought what on earth is happening here, just a stiff cock, no touching and after about a minute and a half he shoots his load. How does that happen?

If you have an answer I would love to know equally if you have anything that makes you think WTF post it here and perhaps someone can explain to us.

Some people can get there with intensive breathing and fantasizing - it's one of the elements of tantra and I think Sting (musician) is on record saying he and his wife would do that in sessions that last multiple hours...

Or the hottest woman/person-of-this-guy's-type is sitting on his face and that's the stimulus!
