i think link enojoyed sex with shiek and since he thought shieks a guy he thought it meant he was gay. so he went and had gay sex with whoever it is on the last page. once he found out zelda was shiek he immediately regrets what he did (and had done to him)

Sheik/Zelda was waiting for Link(like in the game, Sheik suddenly appears from nowhere to give some clue to Link), and finally Link shows himself with a huge boner. Link wants to have some sex with some other girl and asks Sheik if he knows some "STORE" where he could have sex, as he can't ease his boner by himself anymore. Sheik/Zelda doesn't want Link to have sex with another girl, so she/he offers her/himself to be Link's sex partner.
But Link denies it with a reason of "I'M NO HOMO". Sheik/Zelda still forces Link and *insert sex scene*
Skip to last page, Link regretting his decision as his ass got fucked by a builder, because he thought he will feel good like Sheik back then, but it was Zelda all alone. (Link in last panel: "That's why it hurts so bad")
