Harry Potter and the Connubialis Hex/Hogwarts Express/Neville, Luna and Romilda/Let the girls do their thing
From Create Your Own Story
Romilda embraced Luna, one hand behind her back, the other grabbing Luna's tit. Harry could see Luna was tormented, not knowing if it was right or wrong. Romilda's hand left her chest and migrated south. She caressed her vulva lips and Luna's breath changed. Romilda broke the embrace to show her wet fingers, before licking them in front of a puzzled Luna. Then she offered her fingers to Luna's mouth, which shyly licked them.
Harry couldn't believe his eyes. He was amazed by the game Romilda was playing and how well Luna was playing with her. He was now stroking his dick faster. Neville was doing the same.
Romilda whispered something in Luna's ear, to which Luna acknowledged. The girls looked at Harry and Romilida said: "We need the couch please".
"Since you asked so politely", Harry answered with a smile. He removed his pants and changed couches, and masturbated beside Neville. Luna lied on the couch and Romilda straddled her face. Then she bent to reach her lover's pussy. Both girls used one hand to expose the other's clit and started playing with it with their tongues. The ladies wiggled on the couch, and soon, moans were heard.
