"It feels good," he confirms, with a definitive nod. Believe him, Kanji, he's been doing this for over a century. "As long as you use plenty of lube to make things slide easily, and work your muscles open first, getting fucked up the ass can feel amazing. I'll find you some literature - or actually I might have an instructional video somewhere. Anyway, I'll find you what you need, and you can take that lube home and give it a go."
He grins. "You've got so many wonderful experiences ahead of you, Kanji. I'm almost jealous of all those first times you'll be having!"
And he'd be pleased to know he's defying all the stereotypes and showing that gay guys don't have to be skinny and effeminate. Defying the stereotypes has always been something of a goal of his, after all.
