I am a 20 year old college student, home for the holidays. When I went off to school, my parents gave my room to my spinster Aunt Glenda. Glenda had moved back home to be close to her sister, who is my Mom.
Aunt Glenda always wore glasses and kept her hair in a severe bun. Her dress was always prim and proper, and I never thought twice about her sexually.
One night recently, I came home from a fight with my girlfriend. I suffered from major blue balls, and my frustration was at a boiling point.
Glenda was the only one home, and she was sitting in the family room with the lights off watching T.V.
"Tony, you're home early." Glenda looked puzzled.
"Aw, Aunt Glenda, Beth is being a bitch tonight." I huffed, as I sat down heavily right next to her.
Glenda was covered by a blanket, but appeared to be wearing only her nightgown beneath it.
I began to pour my heart out to her for half an hour, and the beers I was pounding down from the kitchen fridge loosened both my tongue and my moral compass.
As I spoke to her, she cooed understandingly, and gently stroked my arm in agreement.
My cock began to swell as I studied her serious sweet mouth, and finally I blurted it out.
"Aunt Glenda, I'm sorry, but why do girls give guys blue balls?"
As I said it, I gestured to the rising lump in my sweatpants.
"Bl-Blue Balls? I-I don't know what that means." she stammered through blushed cheeks.
"Here, I'll show you." I grimaced, as I fought to pull my fat cock free.
When the air hit my prick, it lurched obscenely in Glenda's direction, the purple crown smeared with a film of odorous, slimy pre-cum. My cock was throbbing for a solution, and I didn't care who was in the room.
