The offer

A little reluctant, he left Hermione’s hot body and moved back into Ginny’s embrace. Her pussy seemed to be milking his cock and Harry knew that this was it. He looked to his left, and saw the blissful expression on Luna’s face, the satisfied look on Hermione’s face as she lay there surrounded by her matted hair… then looked back at Ginny, and saw her look of pure love as he slammed into her…
“Fuuuuuck!” Harry yelled out just as the timer went off, and his balls twitched as they began pumping cum into the wet redhead’s cunt. Hermione and Luna jumped up, rubbing their bodies over his and massaging him with their hands, pushing him deeper into Ginny as he kept cumming in her.
“Do it, Harry, all inside,” Hermione breathed in his ear.
“Knock her up, put a baby inside her,” Luna said.

Harry felt himself keep pumping cum inside Ginny’s cunt, surprising even himself as he just could not stop. As the timer went off again, revealing both that Hermione had not stopped him and that he had been cumming in the red-head for thirty seconds straight. Finally, he stopped and groaned.
Before he came fully to his senses, Hermione whispered in his right ear, “Daddy time,” then Luna in his left ear, “You’ll get another shot at Hermione and me next year.”
Harry looked at her astonished, then at Hermione, who nodded… then down at the impregnated red-head he was still inside, and she nodded before taking his lips in a kiss.
