This particular girlfriend was a pretty hot Asian girl (part time model for magazines). I usually go for the very slim/toned girls with smaller breasts, but this girl had a rounder ass and bigger tits. Most skinny Asian girls have no armpit smell at all and you'd have to have your nose touching to actually smell anything, but this new girl had a stronger odor that was noticeable from maybe 1 foot away.
She was familiar with my fetish, and had no problems catering to it, letting me use her armpits any way I wanted during sex. We would even roleplay sometimes and she'd wear a high class evening gown and pretend to fix her hair, exposing her week-long stubble.. Or wearing a tiny singlet and finding excuses to put her open armpits right next to my face etc.
She wasn't slutty but she really enjoyed the "validation" she got by getting men horny. Before she met me, it was always her tits that were attracting attention so she was always in tiny tops making poses that showed her chest. Guys would get closer and stare, she would keep providing a nice view for them. Most of the time she would lower her arms if they got close, as she was conscious about her sweaty armpits. I kept telling her to keep her armpits open and flaunt that but she was too embarrassed to do that.
