Ginny was posting a notice on the Gryffindor message board in the common room, when Harry came up behind her with another notice. His pelvis was against her arse, and he put his arms around her body to get to the board. They had both finished pinning up the parchment but were still in the same position.
Her palms were pressed against the board, and his hands slowly rubbed her arms. He kissed her neck, and sucked on the skin, determined to make a mark.
His hands moved to massage her breasts. She gasped and whispered, "Harry, someone can walk in on us."
"Everyone's asleep," he said, slowly grinding his hips into her, pressing her against the wall. "I love you," he said huskily, she moaned in response, because he had moved his hands up into her shirt to pinch her nipples and squeeze her breasts.
She moved her hands behind her to pull down his pants, and then hers. Their underwear came next and she could now feel his bare dick against her bare bottom. She made to turn around, but he pressed her harder against the wall. One of his hands moved out from under her shirt and down to her wet center.
He moved a finger into her but didn't move it. He slowly put another finger in, and she begged Harry to move them, "Fuck me, Harry." He still didn't move his fingers, but he did squeeze her breasts and nibble at her neck.
He then moved his fingers and rubbed the spot that made her come in seconds. When she was shaking and beginning to hump his hand, he surprised her by shoving his dick in her arse. He slipped his fingers out of her, much to her surprise, and moved his hand out from under her shirt, putting them both on her hips, helping him pound into her.
"We'll come back to that," he whispered as she started to move her hand to put it inside of herself.
He grabbed her wrists and moved her arms over her head so she was spread across the wall. She slowly began to move up and down on the wall as he went in and out of her.
He was having difficulty standing due to the pleasure, so, without stopping his movements he brought her down to the floor. She got on all fours, and he was on his knees, beginning to put his fingers inside of her once again.
There was no sound except the arousing grunts, and the moans of pleasure from the two lovers.
She grabbed his hand helping him move his fingers up and down into her. Within minutess he was coming. His pounding of his hips and his hand into her were growing more vigorous, and she was growing weak because of the pleasure and then they came.
They moaned and she collapsed onto the floor. He continued to hump her as his orgasm climaxed. He grunted and groaned at every pound.
His orgasm ceased, and as they laid together, they muttered words of love and gratitude.
