I was 15 and had finially made my First Holy Communion that sunday morning in May in the class with the 2nd graders[7 year olds].So that i would fit in,i was dressed like the little girls in a poofy,short sleeve top of the knees communion dress and veil with lace anklets and white ‘maryjane’ shoes.Under my dress,my parents had me wear a cloth diaper and plastic pants and tee shirt just like all of the little girls wore under their dresses.I felt very cute and pure in my outfit and everyone commented on how little girlish i looked! After my party was over that afternoon,mom and dad took my relatives to the airport to catch their flights back home.Shortly after they left,my boyfriend,Kurt,came over and brought me a card and a little figurine! He told me how cute i looked,then we started kissing passionately.I was very much lost in the moment then! He put his hand up under the back of my communion dress and felt my diaper and plastic pants and asked why i was wearing them and i told him they are worn under the dresses to symbolize the girls purity and innocence of her baptism when she was an infant.Kurt got very aroused and undid his pants,pulled them down and put my hand on his hard c*** and i started massaging it.He then unzipped my communion dress and pulled it off of me and i turned a little red as he fully saw my tee shirt,diaper and plastic pants.He then gently pushed me to my knees,thrust his hard c*** into my mouth and told me to s*** it!I sucked it for a few minutes,then he grabbed my head and started thrusting it back and forth and a few minutes later he shot his full load of c** in my mouth! I pulled back,gagging,and some of his c** dripped onto my plastic pants and i swallowed the rest!He made me s*** him for a few more minutes,then he helped me put my dress back on and he kissed me good bye and left.I have had a big guilt since then and it bothers me most of the time!
