Congratulations ... you've just had an orgasm, well done.
Now, put your hand back on that cock and start stroking. You're not finished until I say you're finished, you're not finished until the skin is raw and there are callouses on your hand. So, get your hand back on that cock, I don't care if it's not lubed, your eventual tears will act as lube.
