Dura-san's anus was also silver, but it had a properly erotic shape designed to swallow cock. Every single wrinkle led deeper into the hole, promising that a dick would slide in smoothly all the way.
For someone like me who had been jerking off with red, yellow, and clear onaholes, a silver anus was plenty arousing all on its own.
By the way, "falling off a horse from horseback," "a headache hurts," and "feeling a sense of discomfort" are all redundant expressions that repeat the same meaning. I just realized that "jerking off with an onahole" is also a redundant expression!
That said, if I just say "onahole masturbation," people might misunderstand and think I'm jerking off in a banquet hall or assembly hall! Damn it!
I pressed my glans against Dura-san's anus and, driven by a mysterious impulse that felt like sudden anger, thrust my hips forward with all my strength—.
Zubuu! Byuuuuuuuuuuuurururururu!
"Fuaaaaaaaaaaahhh?!"
What the hell is this? It feels insanely good!
