My stepson treats himself to his first assfuck!

Since he seems to have enjoyed the fuck with me and he finally realised that I like him, I hope well fuck more often! That was a really cool thing. Last night he shyly asked me if I wouldnt like him to fuck me in my ass.... I had to think about it again because I always told his dad that his ass only belongs to his dad. The next day he surprised me in my bedroom...
