Bosom Buddies #4: Autumn-Jade and Sierra ...
I don't know if it's one of my favorites, but near the top is the lesbian scene of Autumn-Jade and Sierra in Bosom Buddies #4 from Score.
From the playful beginnings with them trading bras to the unbelievable motion of them sitting up, facing each other and plummeling a double-headed dildo, I can't think of two more curvy women with wide, breeding hips and flying, oversized breasts that could make me go vertical and have to turn it off before I started to spew (and I've been "too slow" a few times to prevent myself from doing just that). Especially that double-headed dildo -- those curves go into perfect, opposing motions and I my eyes are getting way too much of an eyeful of both beauties at once!
I don't know what is the greater fantasy ... to pretend I was that dildo, or to just want to stick my member in their busts while they still got off on the dildo.
