Spiritual swap
The act in which there are two twin girls. The male has sex with one twin in a dark room and can't see her face. The other twin pops in the room and they swap places. The other twin gets fake jizz all over her pussy. The guy wakes up the next morning sees that he came in two girls. Then realizes they were using fake jizz and didn't realize he was having sex with twins. Since he was intoxicated.
Damn, I thought I was seeing double with twins but they both just did the spiritual swap.
