Input: Text: this happened yesterday on my 30th birthday. i'm always a playful guy and like to make jokes and make people laugh. my aunt and her wife, yes wife, both like to make stupid goofy joke when there together. they called yesterday and said they were on their way to target and could they come over after? i told them that would be fine with me. while they were driving they kept making corny joke after corny joke about gifts to get me, mostly girl stuff like barbie dolls or makeup...i'm a guy, and they think thats the funniest thing to joke about since there both lesbians. i really don't understand their humor most of the time but i always just laugh and play along, it makes them happy. so my aunt tell me "were on our way to target to buy you girl flowered panties, would you like that lolololololololololololol" so being the nice guy i always am i played along with them. i told them "ohhh i'd love a pair of flowered panties, my last pair was lost." about 45 minutes later they came over and had a birthday bag for me. my parents, my aunt and her wife sat around while i opened the bag. there was a little electronic bug toy that walks on the floor, a card, and flowered ladies panties! the second i pulled the panties out they busted out laughing like it was the funniest thing they had ever seen. i thought i'd play along so i gave them my "oh my god" shocked and disgusted face. this caused my aunt to die laughing. i figured they picked the panties up at target so there brand new, i thought why not act like a pervert that really loves the panties a little to much. in a big "hey everybody look at the thing over there" sarcastic voice i pointed to the other side of the room as to jokingly divert their attention and then i held the panties up to my face and took a really loud deep breath and said "aahhh now thats a birthday gift!!!" everyone was laughing so hard, i was killing it! my aunt said "lol oh my gosh that's funny, those are karen's". my heart sunk! what. the. fuck! my aunt karen is the slut in the family. i think there is rumor she has "something". i just sniffed my aunts old nasty panties in front of my family. i went to the sink and scrubbed my hands and face but they just don't make water hot enough! i felt sick for awhile after that. welcome to the 30's
