Good idea bro, but try to use the 'Crown Grip'.
If you wanna lift a bottle you can use all your fingers, make a basket and lift it.
Forget the bottle and use your fingers over the glans instead of the bottle.
Now start wanking the Kings head with his crown !!
Happy wanking and good results ......
.... and don't forget the tight ring !!!
Your cock urgently needs a tight but fat ring behind the glans - and then start wanking with your oiled hand.
Aaaaarrrrrggggghhhhh .........................
