Immediately the liquid entered Alan's gut, he felt a stinging pain swimming through his body. It was like a large electric snake was coiling around him. There was no part of his body that was protected from these stings.
Normally, this amount of painful electric sting would have created dark patches on his skin, but surprisingly, his skin still remained healthy.
Alan was not able to bear the pain any longer. He thrashed around, smashing all the furniture as he tried to please his pain. There was nothing he could do that could make it stop.
It was akin to the feeling one gets when he tries to scratch his back but his hands can't reach the exact spot.
After this entire ordeal went on for about five minutes, a different sensation took place.
Was it painful pleasure or simply pleasure?
