First time anal dildo play, edging and cock milking..

I've always been interested in cock edging and milking,plus having my tight ass hole explored with toys and maybe one day penetration by a hard cock..
I met a willing older helper to train my ass to take a dildo after meeting him on an online male bondage/fetish site.
After a few exchanges of messages I decided to meet him in person for a session..
My master was a gent of 55 years of age,prior to meeting him,we had exchanged details of my cock edging and milking and the use of toys to slowly open up my asshole.
My meeting started with me showing up at his apartment,on entering I was instructed to remove all my clothing,including my boxers and then lead to a chair,where in the background was a porn showing of a man being edged and having his cock teased..
My master then bound my hands and ankles to the chair and placed a cock ring around my cock and balls..
After checking that I was bound and couldn't move,my master then proceeded to stroke my cock and pulled back my foreskin to expose my now red pre cum stained knob-the sensation of being teased was great,I could clearly see the knob glisten by my pre cum and this got my master excited as he pulled out a vibrator bead and attached it to my cock shaft and balls..
I was so turned on that I begged my master to place a dildo in my tight never been penetrated ass..
After releasing me from my bounds,my master told me to get on my hands and knees and proceeded to lubricate my ass with some lube and began to insert a dildo into my virgin tight ass..
It felt tight at first,and quiet pleasurable to start,I begged my master to keep inserting more of it,until I couldn't take it..
After some 10 mins of ass play it was time for my cock milking,to which my master masturbated me until I came..
