When one girl some a dude's balls and another sucks his dick at the same time. Both girls must drool and moan as much as possible so when the dude pulls out he can cum all over both chick's faces.
Amanda and Megan enjoyed giving Tom a double blowjob and Amanda really liked the taste of balls in her mouth.

When one blowjob just isn't enough; when you are horny enough that you need to cum a 2nd time after the girl swallows your initial load of cum.
Natalie pulled away after I shot a load in her mouth, but then I pushed her head back down; I decided it was going to be a DOUBLE blowjob.
