three, four or more-some
Less than an orgy, but more than any typical monogamous intercourse scenario, the three, four or more-some is a friendly gathering of a few sexually randy friends, who writhe twist, slide and slip all over each other's naked bodies in a pile, or hot tub, or anywhere. Usually the more the merrier, and often taking the shape of a "round robin plug a hole fest".
Dude, i am so horny, i need like 80 holes to choose from tonight... lets call the guys and girls over for a three, four or more-some. I have a huge bed, rubber sheets, and a camera so we can show all the kids that will be born out of our unprotected random hole plugging.
