For sure, there is nothing more natural than a girl surrendering her body to two guys for the purpose of lovemaking. Of course those horny guys have a biological urge to pump their semen into as many willing girls as possible, but from the girls point if view she knows that a guys semen is a precious gift showing his body has considered her worthy of being inseminated by his seed. To accept the seed of two or more guys increases her feeling of self worth. She happily accepts her role as a preferred breeder.
