Exploring New Boundaries in a Safe Setting

Straight to bi.
I started exploring with letting guys suck me off. I loved it and it was easy to get when they see my cock.
Go to the gloryhole and I could get 3 guys to suck me. Or post a picture and get a lot of replies.
I never had any desire to do anything more with a man.
I had a guy reply to one of my ads. He was local. Actually older. Lived by himself. Clean house. Nice guy.
So I started just going to him for my oral relief. He was super gentle. Passionate about sucking me and making sure I was feeling good.
He would ask if I wanted a message. Or he would go from sucking me to rolling me on my stomach and eating my ass for long periods of time.
With him. It was never hurried, he truly liked pleasing me.
After several months he asked me to fuck him. And I did. Never rushed just pure pleasure.
I started playing with and stroking his little cock. He was embarrassed by his 4" size . But I tried making him feel normal.
I knew I was always leaving his house and him sexually frustrated.
I finally got him to be naked with me. Stroke his cock or have him stroke it until he cum.
Then I started thinking about all the pleasure he gives me and I felt like I should repay him.
I spent weeks thinking about it.
He started wearing panties or lingerie because I asked him to and that turned me on.
On day I had the night free.
I text him to be shower fresh and in panties when I arrived.
I took him to his bedroom.
I layed him in the middle of his bed. Put a blindfold on. I tied his arms wide. I got on him kissing his neck.
I crawled down and started kissing on his small cock outside of his panties. He got to his full 4" hardness. I tour the thin panties off. Started licking his balls before taking his small cock all the way in my mouth. He doesnt even reach my throat. But I can take all his cock and keep it in my mouth.
He keep telling me I dont need to do it to him. But I wanted him to feel pleasure after all hes done for me.
He tensed up and shot in my mouth in 5 minutes. Then asked me to stop as he was sensitive.
He never ask me to do it to him. But about 1 time a month i like to repay the pleasure he gives me.
The cum taste is just salty. I never thought i would be giving pleasure. Just getting. But I'm enjoying it with him.
