Professor nerd is sad because Karma doesn't want to fuck him anymore. Being that we're scientists I suggest that we just make a clone of her! We buy a pair of her used panties offline to get her DNA. As soon as professor nerd hits the button Karma's clone comes to life and is sex crazed! She immediately undresses me while professor nerd goes to work eating her pussy. Her tongue feels so good on my clit! Next, we share professor nerd's cock in a hot double blow job. Then, he fucks her doggy while she eats my pussy. We switch positions and I get fucked doggy while I eat Karma's pussy. To finish things off professor nerd fucks Karma missionary and gives her a nice creampie that I cannot resist licking!
