Double penetration

[1] The sexual act may be pleasurable for the female penetrated partner due to the "blended orgasms" from the stimulation of either or both the G-spot and the A-spot (anterior fornix) in the vagina with the anal nerve endings and the PS-spot (perineal sponge), which is situated inside the wall separating the anal and vaginal canals.

[4] The penetrating partners may derive pleasure from the tightness of the vagina and/or anus, as well as from their penises rubbing together either in the same orifice or through the lining of the rectovaginal fascia.

[6][non-primary source needed] The feminist Bernadette Barton has argued that double penetration, because it usually involves two men's penises close together or directly touching, is an "unusually homoerotic" act in an otherwise homophobic culture.

Barton also thinks double penetration is "bizarre" and "body punishing" because it can stretch a woman's orifices to their physical limit.

This sexual act combines both the doggy style position with fellatio; the "spit-roast" is frequently depicted within pornography.
