Chernobyl Poptart
This act of charity requires 5 partners. The 1st partner will siphon semen from the genitals of the 2nd. The 2nd partner will then swallow the semen and allow it to digest, many hours later once the semen has left the body in the form of feces, the 3rd partner will swallow the feces and then force themselves to vomit it back into the rectum of the 4th partner
I got Chernobyl Poptarted last night, and now there are stains on the carpet
