Gf’s 12” elephant cock ex

Throwaway accounts for anonymity.
This story took place around 5 years ago.
My gf at the time although we were both really young , she was 19-20 and I was 23 had already had her hoe phase . I also had my fair share of experiences but nothing like her ofc.
She was pretty , slutty and athletic . Just exactly my type.

She was always great in bed in every way possible .
Her experiences allowed her to know a man’s body and how to make him cum multiple times. A proper freak mentally and physically already.
One day we were having a little playful argument in which I boasted I definitely was the biggest she is ever had since Im around 8.5 inches long .

I was so fucking wrong. She immediately got annoyed and humbled me by sending a pic of her ex’s 12.5” pornstar cock . I remember just gawking at the pic not being able to believe I saw a man with a cock hanging to his knee . It seemed 100% real which turned me on ridiculously much (my gf didnt know I had a hotpast kink) and I remember instantly cumming .

Ofc I told her its fake etc just to hide how horny it made me . From that point on I had his pic saved and jerked off to it thinking how he fucked her like no-one ever could .
She also shared other very hot stories when she got annoyed but that hotpast moment triggers me till today…
