In this video in the min 6 starts the tittyfucking part, that cock is clearly big like 7 inches, and those boobs are DDDs and yet that cock dissapears like it doesn't pop out at all at the other side of the cleavage, can any tittyfuck expert explain to me why or how does that happens? I have seen 7 inches cocks fucking bigger tits and they always pop out and stuff they never completely dissapear, I wonder what trick or physics is involved or angle they there big cock didn't popped out of those DDDs..

I have a 6 inch shorty and tittyfuck an H cupper. Sometimes I pop out, sometimes not. I can tell her to let me pop out the top so I can feel it or tell her to keep me buried each stroke... it just comes down to the position and how she's squeezing em.

I'm 6" & my wife 34DD , I have to make an effort to come out the topside !

I have a 7" cock and my wife has H cups. I do not pop out the top of her cleavage. But as the first man to answer stated, it really has to do with the position of the breasts. The way the woman squeezes them together.
