Tommy Measures Up

This was a novel idea that Tommy actually thought of himself. Get one swat for every Cm of dick he has, both soft and hard. So he measures up and see that soft he gets 10 swats, a normal start. Then he gets hard and and gets 16 swats for that, a decent size cock. But its all a bit much for him and as he gets the 16 swats he starts to jerk off, finally blowing a load onto the floor. he looks like he enjoyed the whole thing and his cock stands rock hard even after he dumps his load so its clear he did.
