When a female does not want to have sex, the male ejaculates onto the females back while she is sleeping and puts the sheets over her. In the morning, the female wakes up with the sheets stuck to her back like a cape. Therefore looking like superman.
when a guy jizzes on a girl's back and tells her he's gonna wipe it up with a towel, when really he just throws it on her back so that it gets stuck and looks like superman's cape.
preferably with a red towel.
To remove the sheet from a sleeping girl, then proceed to ejaculate all over her back without waking her up. When done, put the sheet back over her and make sure the sheet sticks to her back. Then throughout the night your manlove will dry. Resulting in the sheet being glued to her back with your juices. And finally when she awakes and gets out of bed she will get up with the sheet stuck to her back like superman's cape.
