When it comes to cock, it seems that many of us believe the more the better. In porn we can see this by the rising popularity of all kinds of exciting films featuring group sex, orgies, threesomes, bisexual men and other kinds of wild erotic tastes. One shines above all the rest as both a fantasy of free sex explorers and a popular theme in x-rated movies: double penetration. This is where a girl is taken by two cocks at once in all different ways. Many women fantasize about this, just as many men seem eager to watch films of it taking place.
Double penetration just means two cocks, so one way it can happen is with one man fucking the cunt or ass while the other fucks the mouth. Sometimes called humorously the Eiffel tower position or Chinese finger trap, the two men take her from either end while she bounces happily between the two, sucking and getting fucked at once. In some cases, the men will both fuck her mouth at once for a double blow job, which can be very erotic for all involved if the men enjoy the feeling of the contact between their cocks.
Comfortable men are certainly required for what many seem to feel is the holy grail of double penetration, which is either two cocks in the same pussy or one cock in the vagina while the other fucks the ass. This usually works best, as frequently displayed by porn stars, with the girl in the middle of the pile with one man on top and the other underneath. First the man lays down, his cock already erect while the woman climbs on top, probably placing it in her pussy. Then the other man comes up from behind and carefully penetrates her lubricated asshole. Although the cocks do not touch directly in this scenario they can be felt through the thin membrane of flesh.
