The only way a sissy is allowed to have sex with a woman

I couldn't even remember when was the last time I had sex with a woman, let alone the last time a woman was willing to have sex with me, until I met her, she told me she had the fantasy to have sex with someone like me; the sole idea got me excited so I didn't ask for details until a few days before the encounter when she asked me to wear my chastity cage and what size of dildo my ass would feel comfortable with... I should have known better... But If I'm super honest, I really enjoyed it...
