Dogxxx

I have a rather big German Rotty and for the past two years he gives my ass a good fucking like four hours worth every three days or so. The first time I kept his knot out of me but I held him right up to his knot inside of me and his cock got so hard and big it was almost to big for me, little by little I got use to him and one afternoon I decided to let him tie with me like he's been wanting to do for months and god did he ever. For over a hour he was tied to me making me his bitch pumping his seed into my ass and I was in heaven.
I now own 2 German Rotties and they both have me for their bitch.

I've done thast five times already, its a really amazing feeling getting filled up by his knot even tough i am a male. It only hurted the first two times. But i still feel kinda bad because its unnatural. But this is probally because all of the hormones i am getting, cuss i am 16 y.

I would love to do that too!
