It’s all began when Harry has stumbled by accident on Teddy occuped to masturbed, only he was not as a male but as a female. Surpised and excited by the situation, Harry propose, without thinking, to take the experience further along and Teddy accept eagerly; both thought it will only be a one time thing, but after this experience Teddy cannot stop to come again, again and again, becoming totally addicted to having sex with Harry.

Ginny discovers quickly the new relationship but in place of feeling anger or betrayal, she is aroused and wants to join the fun, furthermore she discover that Harry, who has never lacked in stamina and libido, had an increase in both and she wonder if it will the case with a new girl or even multiple new girls.

Hermione complains about Ron to Ginny, saying that since the birth of Hugo her husband has touched her lesser and lesser. Ginny hasten herself to propose to try Harry, eager to test her new theory. Hermione is quickly converted and Harry gains a new girl and a boost in sexual progress.
