The gentleman caller then copulates the "lady" anally (although no penetration is actually shown). During this mission, Mercury becomes lustful of Lara and copulates with her, begetting twins. In the castle Beauty meets another slave, Prince Alexi, with whom she copulates passionately. The two seasons are personified as brothers, born after Enlil copulates with a "hursag" (hill). After pairing, the male frequently copulates with the female. As in many other animals, the dominant male copulates with the female. The female continues the calling as the male copulates with the female. The pair copulates for about three minutes. Usually the pair copulates several times, even in orders that lay only one egg per-clutch. The heads used are swapped each time the mammal copulates. One brother, the dominant, copulates while the other male, the subordinate, helps. Each time it copulates, it alternates heads in sets of two. Finally the male mounts and copulates with the female. The pair lands and copulates, a process which can last more than an hour. Each female copulates with many males, and vice versa.
