Called it, I KNEW that to have Sex with Shirahoshi normally, Luffy would have to use Third Gear to fuck her. Too bad we couldn't see him get more than a Paizuri...
@SeekerOfDestiny. The Doujinshi artist wrote it somewhere in his notes that Luffy blew up his dick with Hone Fuusen, perhaps his logic was that Luffy could blow up his muscles as well as his bones. The DICK is technically a muscle, afterall. Either way, not my problem but his for getting information he should know wrong.

@Luke78 the author probably wasnt sure how the vagoo of a mermaid works. personnaly i suppose its jus like with reptiles and some fish, that its usually shielded by scales that can be moved out of the way if needed.

Actually, Gear Third wouldn't work in this kind of way. Gear Third is also called "hone fuusen" (or similiar) which translates to "bone ballon". He actually blows his bones up to make them bigger and we all know: there ain't no bone to pick in a mans dick :p

Actually after the time skip Luffy overcame Gear Third's side effect of making him small. Great comic in general, I wish he came on her face though.
