It was a little after college. My girlfriend and I were at her apartment and she just kept wheedling me (I never could say no when she gave me that face and those big brown eyes). We went to her bedroom and stripped, she put a small dog collar on my cock and then forced a little padlock through the material of the collar. After making sure it was secure, she attached a chain. Leading me out to the living room (with all the shades drawn), she put in her favorite movie and had me suck on her toes and tits while fingering her clit to pleasure her. (I never went as far as eating her, for which I regret for we broke up shortly after that.) Now when I want to get turned on, I think about that night, being led around by the cock. (I almost went nuts one day in a Spencers when I saw an item called the big dog leash, but didn'y have the guts to buy it.)
