Sis Wet Experience 

Just when you are about to bust a nut up in your girl, you ask her if her sister gets as wet as she does and hold on for the bucking final ride.

May also be used in the case of one’s sister-in-law as well. The outcome is usually the same.

What was all that screaming from your room last night braahhh? Wild sex? Had a sis wet experience braaaahhh.
