purse breast separation 

a temporary physical condition in which the breasts of an adult female are separated and thus accentuated by a strap, usually of a purse or seatbelt, that runs between them

I couldn't help but notice your purse breast separation from that seatbelt, and it is quite arousing.

Breast-Volarity Curve

The standard against which optimal breast size is gauged in seeking a suitable mate, etc.

The optimal breast size is equal to the amount that can be fit in one's hand; any less is not enough and any more is excessive, wasteful, and unnecessary.

The curve follows a sharp Gaussian/Cauchy–Lorentz function and distribution.

f (x; 0,1) = 1 / π (1 + π^2)

This is informally known as "The Hand Rule."

Person 1: Wow, she has exquisite breasts.
Person 2: Eh, they're too large.
Person 1: Nonsense!
Person 2: Where do they fit on the Breast-Volarity Curve?
Person 1: Ahhh, good call.

breast relief

When a man puts his stiff cock into the cleavage between a woman's tits in order to achieve orgasm. Either of them can use their hands to press her tits together around his cock, and he moves back and forth just like fucking until he cums. She will receive the sperm between her tits or on her chin and neck depending on the size of her tits and the length of his cock.

Press your sexy big tits together darling, I will give it to you and have a breast relief.

Breakthru 

When you wake up, feeling like you had sex with your crush for the first time. Then, get your band mates together and decide to perform on a fast moving train. Its also a kickass Queen song.

Guy 1-" Why on earth, is that band performing on fast moving train?"

Guy 2- "Idk, either they're having a Breakthru moment or just bunch of Queen fans."
