First time wax at a girl friend's house

Well this is funny, I have this friend, she is a girl, and a friend, we sometimes met up on a Friday night for drinks hers,I was round there a few weeks back, yer I go nude, she does at times but this day I was hairy lol not bothered for ages. I mentioned thst I hate the look, she normally sees me smooth. She then says she has a wax machine and can do it properly, well I've never been waxed before, just use hair removal cream, and she said she will wax me if I want. Fire it up I said. It takes about 30 minutes to melt the wax, so I'm sitting there nude waiting for this machine to melt the wax, I don't get hard when there as just friends, but this day sitting there waiting to be waxed, my first time, i did start to get a bit.. Now I've never been waxed before as i said, so she tested a bit on me and asked if it hurt, to be honest it never, so I said carry on. I'm laying there on a towel on the floor when she put the first bit on, then rip, then next bit, rip, I felt the skin and yes so totally smooth. She was doing just under my belly button to start with moving down to just above my covk. I never got hard at all until she said, can I move my cock to the side to do there. This is when I started to get a bit semi, she done the one side while I'm holding my cock out of the way, then I moved it to the other side, by this time I was hard, I hid it behind my hand and arm while she waxed thst side. Now is the time to wax my cock, she said move your hand.... which I did and I'm sticking straight up, she looked and just went, it happens lol, so now she putting the wax on me while I'm rock hard, she holding me in one hand or moving it around and just carrying on as normal. She then said pull my balls so the skin is smooth then continued to wax them.. once they were done she said all finished??? I said can't leave me like thst, smooth at front, hairy at back lol, she asked what? I said your need to wax my bum lol.. So now I'm on my front while she putting wax in my bum crack and getting there smooth., all this time in still tock hard.. Once she had finished she said to stand up so she can check to see if any left behind, so I'm standing there, cock in front of her face and she rubbing her hands over me too feel for any loose hairs, man I don't know how I never cum there and then. She never done anything to me, but I'm standing there rock hard, ib was tempted to start wanking but never, I just stood there, admire myself in the mirror trying to find loose hairs, I kept on saying here is one there is one while she then waxed them off. I stayed nude all night, hard must of the time, posing , lol, whst a brilliant night and yes waxing does list a lot longer
