Inside-Out Blowjob
The act of a woman widening the hole of a man's penis using various tools. The woman then sticks her head inside the man's freshly widened hole and pleasures him from the inside.
As weird and painful as it may sound, there is no better feeling in the world than your girl giving you an inside-out blowjob. Just thinking of her licking the interal lining of my cock makes me rock hard.
