Return Velma's Sweater

I walked back to Velma's room, looking at her sweater. Maybe she wouldn't notice the cum stain?

I knocked on her door. She was still in her bra and skirt when she answered.

"Hey, you got Shaggy's shirt!" She said, letting me in.

"Yeah! Here's your sweater back!" I said, handing it over.

She looked right at the stain, "What is this!?" She yelled.
