A titfuckblowjobis a combination of the two words in the word. The guy places his penis between the girls boobsand the girl squeezes them together. Then, the guy moves his dickup and down the girl's chest between her breastsand when it gets close to the girl's mouth, she sucks it. When the guy is ready to blow a load, the girl stops squeezing her boobs together and the guy pulls his dick out. Then, as if he were getting a blowjob or titfucking, he blows his load all over the girl's face and chest.
Dude. My girlfriend and I had a titfuck blowjob marathon all night!
