Bottle and kefir in the pussy

Last summer I had a photo shoot with kefir))) I was covered in kefir! naked and in panties))
And then I decided to try to fuck myself with a bottle of kefir!!
The bottle turned out to be too thick and only slightly fit into my narrow pussy...
But the cool thick kefir filled my pussy completely!
I experienced a very strong orgasm from such a filling!
And then, when I stood up, the kefir began to flow out of me in a thick stream!! And I caught an orgasm again!
It was a wonderful sexual experiment!
I have a question.... where can I get so much sperm.... instead of kefir...
