Harry Potter and the Connubialis Hex/Hogwarts Express/Neville, Luna and Romilda/Sit the girls on his lap
From Create Your Own Story
Harry reached for the girls' hands. They looked at him and giggled. They pulled on his clothes, stripping him naked, then sat on his thighs. He caressed their bare asses. Romilda took Luna's hand and set it on the boy's dick. She could feel it throb in her delicate hand. She gently stroked it, spreading some pre-cum in the palm of her hand and on his cock. His breath got harder. He was ready to fuck.
What will Harry do?
