Go in of course.

Ginny wasn't about to miss out on finding the truth.

She moved to the door and carefully opened it. She slipped in quietly.

Once inside she was stunned by the sight.

Harry had Hermione on her hands and knees and was fucking her hard! Hermiones face was buried between Luna's legs and eating her pussy!

'Merlin this is fucking hot.' Ginny found herself getting wet at the sight.

She still couldn't believe the show she was seeing. Her three friends were fucking. Then Luna's voice was begging.

"Master! Can I cum? Please?!"

'MASTER?!' Ginny went pale at that.

"After I fill Sluts pussy." Harry ordered.

Hermione was moaning into Luna and the blonde was twisting her nipple rings as she fought off her orgasm.

'They're fucking and Harry is their Master! They're sex slaves. That explains everything!

She saw Harry slam his hips into Hermione and she could tell he was cumming.

Luna moaned louder and came all over Hermiones face.

The three jerked against each other and fell together.

She saw Harry pull his cock out of Hermione and she was stunned again.

'He's bloody huge!'

She was so enraptured she was standing stone faced and didn’t notice Hermione pulling her face out of Luna's pussy and sitting up.
