An extra penis will not be superfluous if there is a second pussy

In general, girls are very socialized creatures and sometimes even too socialized. Judge for yourself - if they even go to the toilet as a couple at least, will one girlfriend refuse to invite the other to visit her in the evening, provided that there is sex with her beloved guy. Well, in such situations, a girlfriend who will support a friend’s dick and guide him in the right direction will never hurt... and this is by definition and in fact too!
