It's from a Gintama Dj by Harada

What the hell

I've seen porn with guys fucking themselves. Amazing (๑•ㅂ•)و✧

Thanks for reminding me of this one, I completely forgot about it and here you go

I've re-read this question almost 10 times, hoping that I've just misread it...
Yaoi manga where a guy literally fuck himself? Like he can detach his dick and put it in his ass or suck it himself, or detach his head (dulahan) and his detached head suck his dick? Something like that?
