Lots of masturbation first time stories seem to involve sisters. Well this one does too. And it is a sort of watershed sexual thing for me awakening two maximum turnons:hairy pussy and being watched jerking off by a female showing hers. And at age 13(me)and 15(sis) this all began.
It was just before bed and having brushed my teeth and jacked up a semi bone in the bathroom I came out anticipating a good jerk off in bed and passing my sister's room she called me in. She was kneeling up on her bed in pj's. I stood in the door in just pj bottoms which were moderately tented by what would soon become about a 6 1/2 inch puberty hardon. Sis asked if I had hair yet-man I did for a year already! Then she said Mom wouldn't be home for another hour and she looked sort of weird and her tits were showing hard in her pjs. I said lots of hair and she said bet not like she did, let's show it.
With that she pulled her bottoms down to her knees. My first sight of a live cunt and it was a vast triangle of chocolate colored hair on a mound between her thighs. The immense bush was parted in the middle by pink lip type things poking through and wetting hair around them. I was overwhelmed and speechless and she got up and pulled down my pants.
Well for the next 15 minutes or so I leaned back against the wall with my pjs around my ankles and masturbated as my sister sat on her bed and watched with her hand buried in her hairy cunt up to her wrist. I exploded receding shots of sperm on the floor from nearly to her bed back to the last at my feet. It was all I could do to pull up my pjs and stagger out to my room. I jerked off at least three more times by morning with that triangle of rich cunt hair burning in my mind. And I hope some hot lady is reading this with a furry twat gaping and sputtering cum along with my ejaculation.
