She wanted to see my dick in panties

Once, I decided to shave my pubes as a surprise for my girlfriend. When we were together that night and she took off my pants, she laughed.

"What the hell?!" I asked why she was laughing.

"It's just looks so small and cute like that." I was offended until she said, "I just want to see it in some panties." I don't know why, but the idea turned me on so much. I became addicted immediately to the sight of her sucking my smooth cock and balls through a pair set of women's lacy underwear.
