Unwilling to give up her view of Ginny frying, Hermione got on her knees in front of Harry and lay her body across the low table in front of him, lifting her young ass into the air as her diamond hard nipples pressed against the lacquered wood. She reached back with one hand, her eyes never leaving Ginny or her tube even as she spread her sex invitingly for her best friend's use.

Harry stared, caught between the show that Ginny was putting on for him and Hermione's positively dripping slit. He reached down and touched it, stroking the soft petals of her sex before driving his fingers into her pussy without any warning.

"Oooouh!" Hermione moaned, bucking back against Harry's probing digits even as she stared at the redhead finger fucking herself in front if her. Distantly, she imagined that Harry's fingers were hers, that Ginny was playing with her cunt instead of her own and she marvelled in the illusion as she watched Ron's sister's final show.

Hermione was soft and damp, her pussy warm and welcoming, and Harry needed no further invitation to indulge. His fingers came free with a wet squelching sound, soaking wet with Hermione's own arousal. Unsure of what to do with them, Harry wiped them dry on his friend's frizzy brown hair; Hermione didn't object, allowing Harry his fun as a sort of thanks for giving her the gold to buy their friend. The scarred boy grabbed his still erect cock with the same hand and carefully guided it into Hermione's beckoning cunt, groaning in satisfaction as Hermione stopped spreading herself open, allowing her sex to envelop him completely.

With her eyes still glued to the redhead in front of her, Hermione began to rock back and forth on the Boy-Who-Lived's turgid rod, enjoying the sound and feel of her friend's balls as the slapped against her body. The oil was rising now, and any second it would start to splatter into Ginny's chamber from the tube it began in.

Harry grabbed hold of Hermione's hips with both hands, impatiently slamming his cock into the depths of her cunt as he took control of the rhythm of their coupling. The inexperienced virgin took to fucking with abandon, gleefully using his friend for his own pleasure while she stared rapt at the show in front of her, rolling one if her nipples between her finger and reaching beneath her body towards her pussy to play with herself even more.

Ginny was frantically finger-fucking herself, playing with her own tits with her free hand. She could hear the bubbling hiss of the boiling oil as it rose, and she knew that once it hit her fun would end and the real show would begin. She was close! So close! She could feel it! If it wasn't for this spell she'd be done already! But the tingling numbness of Hermione's charm had knocked her prize out of her reach.

Hermione shivered in anticipation as Harry neared his climax. His thrusts were getting shorter, more erratic, and she could see that the oil was just about to boil over into Ginny's tank. Ginny yelped as the first bits of oil hit her, sizzling against her skin and adding an almost random set of angry red spots and streaks to the redhead's already haphazard collection of freckles. The yoinger girl's shout sent her crush over the edge as well and Hermione could feel Harry's warm cum coating the walls of her sex in powerful spurting jets. She didn't care, watching raptly as the oil began to splatter across Ginny's pale young tits instead. She wasn't about to miss a single second of the spectacle in front of her.

Harry pulled out, a few final shots of cum landing on Hermione's back and in her long brown hair. He could feel himself already starting to get hard again as he watched his white cum oozing from between his friend's legs. This was incredible! Absolutely incredible. And it was all Ginny's fault. He needed to thank her.

Harry walked towards his redheaded soon-to-be-meal, his cock swinging between his legs where it emerged from his open fly. Ginny's eyes widened as she watched him approach, her gaze alternating between his smiling face and his dripping cock. She held in the pain, straining not to react as the boiling oil splattered across her once pristine skin. This was for Harry. This was important.

"Thank you," Harry spoke, leaning in to seize the redhead's lips with his own in a brief, almost chaste kiss. Ginny wanted to lean in, to pursue his lips as he withdrew, but she couldn't. She was trapped. The collar Hermione had transfigured keeping her in place and preventing her from deepening their first, and almost certainly last, kiss the way she wanted to.

“Of you take a few of her hairs I can give you a surprise,” Hermione commented, sultrily.

You didn't need to tell Harry twice, not after Hermione's track record with surprises so far. Ginny barely realized what was happening before Harry had finished tugging several long red strands of hair from her trapped head and turned around to return to Hermione.
