My Big Dick Young Neighbor Continued! Part 3

I again have him come to my home after he gets off work. He strips in front of me before I have him shower. I started to watch him shower, it turns me on! I brought up somethings during his shower. I asked him if he would be open to trying something I've always wanted to try. He asked what it was. I told him I wanted to fuck him. He kind of laughed and told me I fuck him all the time. I told him no like I want to put a strap on, on. Use it to fuck your ass, make you suck it! He finally asked me since he's submissive and he is letting me explore my dominate side. Would I like to make him my sex slave? We basically have a Dom n sub relationship. I was not sure what he meant. I know we can't be in a relationship publicly. So he said we can commit to each other sexually! I would be his dominate woman. Him my submissive man, my sex slave! I keep him naked when in my home, I make him stay hard in between my feet or in my hand when we are just relaxing, I use him to do what ever I want sexually, besides our first night I have not let him have an orgasm for 5 nights. He has blue balls since! He makes me want him so much everyday! I told him yes! After his shower he worshipped my whole body! Gave me a full body massage. Licked me to my satisfaction! Then I kept him hard in between my feet while we looked for a strap on for me to buy. We settled on a purple 6 inch. Same size as his cock, my favorite color! I'm so excited for it to get here! I want to fuck him so bad! He is coming over again tonight!
