Intercrural intercourse (dictionary)

BoyWiki Dictionary: Intercrural intercourse

n

¹ Intercrural intercourse is the sexual activity which consists of a male placing his erect penis between the thighs of another person, whether man, woman, boy, or girl, to simulate vaginal or anal sexual intercourse.

This has been famously called "Greek love," though Greek love is more commonly (but mistakenly) believed to consist only of anal intercourse.
