Grinning widely at the two girls before she got up to get the strapon, Heidi realized how lucky she was at this moment.
Heidi chuckled at Ginny's loud enthusiasm. The redhead was always like that during sex, in difference to Tracey's more reserved acceptance of new things.
Kneeling behind Ginny, Heidi took a moment to just watch as Ginny's mouth was on Tracey and the way Tracey reacted. A small part of her felt a slight tinge of jealousy but it was quickly forgotten by how sexy the sight was.
Slowly, Heidi rubbed the fake phallus against the Gryffindor's folds, teasing her as the brunette's hands went to hold Ginny's hips. "Ready?" she asked. With Ginny, the asking was more of a tease than an actual question of concern. She knew Ginny was ready.
Not waiting any longer, Heidi slid the strapon in Ginny's cunt, not stopping until she got it in to the hilt. Keeping it still for a few seconds to let Ginny adjust, she soon began to pump it in and out as she looked over Ginny's shoulder to watch the redhead lick her girlfriend.
