where a man places his dick in between some nice firm tittys usually DD+ and makes his dick rub up and down, I'd use lubricant or you get burns I know. This is good for horny guys who have easy girlfriends, I would suggest doing this if your not ready for sex.The man usually should cum in there tits,neck,face and mouth.
John: I titty fucked sarah last night, my eyes went to the back of my head.
Steve: Wow! What size tittys has she got?
John: 40DD . . She said that before we had sex, that I had to titty fuck her.
Steve: Holy shit! You gotta let me have some of those tittys!!!
