My boyfriend is very crazy, the BDSM goes

My boyfriend is very crazy, very out. The other day he took me to his basement and showed me a very rare collection of leather gadgets, straps and weird things that when I found myself trying them I could not believe it. When I wanted to realize my boy had tied me against a kind of bed that looked like a colt of tortures, and began to wrap me up like a sandwich and to jerk off and rape me in the ass until I came, completely at the mercy of his touching.
