Eat the watermelon
After you finish having sex, you dump your cum into a watermelon, stick it up her butt, and then chow it down like it's a snack.
I ate the watermelon after I finished. It was like a post-sex snack.
He stuck the watermelon in her butt and then ate it. It was gross but worth it.
She said she was eating the watermelon, but I know she was doing it for the fun.
