Refers to when a dude jumps your bones in a flying leap and
plops down "in perfect
alignment" on top of you, with his cock inside your love-tunnel and his hands
cupping down on your boobs.
Three-point landings are very pleasurable in and of themselves, but give da guy an extra "point" if he also lands
wif his lips on yours, so dat the two of you can start "double-thrusting" (i.e.,
simultaneous lulu and tongue-action) immediately.
