Shimakaze's dialogue in the first panel slightly changed to preserve the pun more. You could also use 'spurt forth/final spurt' and link that into ejaculation, though.
Eheheh~
I'm number one!Shimakaze-chan, you're amazing!...not that getting off.
抜く /nuku/, amongst other things is both 'overtake/surpass' and slang for 'male ejaculation'I'm also quite skilled at getting them off myself!Oh, you're quite adept at getting things off too, aren't you, Shimakaze-san.Well, I am the anchor, after all!
Getting things off my tail is what I do!
