When in the middle of a "69" the guy who is on the bottom brandishes a large rubber (preferably black) dildo and proceeds to insert into his GFs ass. It usually ends in her cumming until she's completely incoherent.
I took my very hot and sexy G.F. to a motel on 8th street and while we were 69ing, I eased a black dildo into her big, sweet, hot and unsuspecting ass. After introducing her to that hot and nasty Rubber 70, she really wants to marry me!
