Best foot fetish experience?

[In****]

Laying in bed with my Gf watching something. I remember she was snacking on something...I was laying behind her...she must have known I wanted it...she shoved my face in her ass and just melted my dick between her feet. I was cumming b4 I realized wut she was doing. I was genuinely embarrassed and confused...I was still recovering when she gently asked me to get a towel...not even making glancing at me...I was genuinely intimidated and turned on...
