Someone walks in

As Hermione was below the desk, Harry moaned a bit, taking his cock deep down her throat. His homework lay in front of him but he struggled to do any work, as good as his friend was sucking him off. "Fuck, Hermione," he called and reached below the table, finding her head and putting one hand on it, to control her movements.

Just as he was enjoying it fully, there were the sounds of steps signalized that someone was coming down the stairs to the boys' dormitories. Harry bit his lips and pushed himself into a upright position again, giving Hermione a small signal. She slowed a bit down sucking him off, but just enough to not make too many sounds slurping on his cock.

A moment later, Ron appeared in the doorway and looked around the mostly empty room. "Ah, there you are," he said as he noticed Harry on the table. "Still doing your homework?"

"Uh ... yeah ...," Harry said. "I struggle to focus on it a bit."

"Yeah, stupid topic," Ron said. "Maybe we have to ask Hermione if she could help us out with it."

"Oh ... yeah ... probably," Harry said and took a glimpse below the table where Hermione was still sucking him off.

"Well, I'm going to bed," Ron said and disappeared upstairs again.

Not one second too late, as next Harry found himself blowing a load into Hermione's mouth. His bimbofied friend was eagerly sucking every drop of cum from his cock, before pulling off him with a slurping sound.

"That was good," she said with a grin and a giggling sound. "What now?"

Harry looked down at her. Her huge boobs looked so inviting inside her blouse. But what if someone else walked into the room? He wondered if the cookies had a permanent effect or if they would wear out. Better not risk too much. The scene with Ron was really close already.

"I think we should go to sleep," he said. Hermione pouted but didn't protest too much. She giggled as he gave her ass a clap, sending her upstairs. Before he headed upstairs himself, he gladly remembered to pack the remaining cookies and store them safely away, together with the strange ray gun.
