A fantasy
Myrafur drew x-rated art and asked for drabbles...
Ron had wanked to an image of a naked Hermione since Fourth year. Ever since the Yule Ball had opened his eyes, he had closed them and imagined those robes coming off.
In Fifth year he added the tie as a blindfold. There was something about the prim and proper Hermione being able to let go while blindfolded.
In Sixth she was usually writhing, speared, on a naked Harry’s lap. So? They were his two favourite people in the world.
In Seventh he had finally seen Luna naked, and hadn’t been able to resist placing her between Hermione’s spread thighs.
