How can we go public.

I don't even know what to call him, My aunty is married to my moms brother and My aunty's brother is the one I don't know what to call him, Is he my uncle in law, My second uncle, or is he no relation to me at all....One thing I do know is he is my lover.
On my 19th birthday I was in the bar and a guy come up to me, He said "Hey, Are you Maddison *****", I said "yes" and he introduced himself as Wade, My aunty's brother. We had a drink and he wandered off after and I didn't see him again for an hour or so but toward the end of the night I ran into him again, He has a very nice body and is a good looking guy but he is 41, he is tall, Handsome and kind of a rough looking guy, Shaved head, tattoos and I am pretty sure he could F up almost any dude who squared off with him, I asked him if he was driving and he said no, He had too much to drink to drive so I asked if I could share a cab with him, He said I could and once in the cab I started flirting hard, I was showing a lot of leg and kept leaning over so he could see down my top.
He had given the cab my address and when we were getting close to where we would turn to go toward my house I told the cab to go to his house, He gave the cab his address and we both got out at his house. We went inside and made out, He pulled back and said "Maddison, I don't think we should", I stood up and peeled off my top, I am a short girl 5'3" but have Large **, A great ** and thick, Muscular thighs. He sat back and bit his lip looking at me and I straddled his lap. Needless to say it wasn't long before I was on my knees with easily the biggest ** I have ever seen right in my face, He was only half hard and it was just hanging there.
I licked my lips and started sucking him and he just got harder and harder and I could barely fit it in my mouth when he was fully hard, I did my best to ** it and then he stood me up, Laid me on the bed and knelt at the foot of the bed, OMG he is amazing at oral, He was softly licking me and had one hand wrapped around my thigh rubbing my ** with his fingers and had a ** or thumb from his other hand rubbing my ** hole. I was losing my mind and my self control when all of a sudden I felt something I have never felt and didn't really know what was about to happen but he pulled back as a little bit of my...Lady juices squirted out, I panicked and clenched and covered myself until I was able to make the feeling go away.
I was so embarrassed and almost bailed out but he calmed me and looked down at me saying "First time?", I nodded and said "Oh F ya", He spread my legs and rubbed his shaft on my wet lips and said "Next time just let it happen", I said I would try and he pulled back, Pressed his ** against me and pushed it in, I was like "Oooohhhh **, Hold o, Hold on, You're huge, Just be gentle" He tweaked my nips and did absolutely everything right and was able to get it in, I knew he was as deep as he could go and I looked down and he still had more I watched him slide in and out of me and stretch my lips with every stroke, He was big enough that it as uncomfortable but amazing at the same time.
He is very dominant in bed which works well for me but I have never had that before so it was a bit scary at first, He made all my fears melt away and it is a very loving dominance but also very dominant, He tells me I belong to him and my ** will never have another ** unless he tells me to which is sort of scary because I don't know if he will tell me to do one of his friends or something but I know I won't be allowed to say no and I don't know if I physically could say no to him. We had ** that night over and over and I had so many ** that I lost count, He did make me squirt and was choking me at the time telling me not to stop it, It was so amazing and so embarrassing at the same time because it was a massive squirt, He was even surprised at how big it was.
We have been seeing each other for 4 months now and he has absolutely blown my mind every time, It is just a surreal experience every time but my problem is that he wants to go public but I don't know what my family will say, I am sure he is going to be the bad guy and they will say he seduced me etc.
