my best friends alpha father

Hi Sam, I submitted this earlier but not sure it went through so doing it again just to be safe, I had lunch with my college best friend John on saturday who I hadnt seen in a year, I arrived at the restaurant 25 minutes early as it was a saturday and busy, I got a table for two, not long after I arrived , Max-Johns father arrived, he is a total dilf, late 40's, silver fox and radiates Alpha energy, he was wearing a navy pinstripe suit and black loafers, carrying a briefcase and a tan coat, I had briefly met him once or twice over the years but this was my first proper time meeting him one on one, he strolled over casually casting a cool glance at me , I said hello and he grunted, i asked if he wanted to sit down and wait for John who was parking the car , he said yes , we walked back to my table for two (I wasnt expecting three people so there was only two seats) there was a woman behind me by herself I asked if i could use her free chair for john she said no problem, I put it at my table and what happened next floored me,Sir Max spread his legs out across from his seat on to what had originally been my seat propping his feet up and put his briefcase down on johns chair, he said ''you dont mind do you my feet are aching from working and my briefcase cant sit on a dirty floor'' I was stunned and secretly turned on at his display of dominance over me, I said I understood and it was no problem, there were no more free seats, I was totally confused, I asked him where I should sit and he said right here and pointed to aspot on the dirty floor right next to him, I obliged to be polite and sat on the floor next to him as he propped his feet up,i could tell he was enjoying it putting me in my place, not long after he asked me to check his coat and order him a cappauchino ,I expected him to offer cash or his card but he didnt, I didnt say anything as I checked his coat and ordered his coffee and brought it to him,still waiting to be reimbursed (my mistake) he just grinned and said good boy, i sat down next to him on the floor fixated on his feet as he sipped his drink and scrolled on his phone, after 10 minutes John finally arrived,John was confused to see me on the floor and asked what  I was doing down there, Max answered for me and said I was more comfortable down there, I smiled making a joke out of it and said yeah much more comfy, Alpha Max moved his briefcase for his son John to sit down on and handed me his briecase saying he didnt want it touching the floor and asked me to hold it on my lap all during lunch, I agreed to and held on to it for dear life, i took my original seat where maxs feet were spread out, John insisted I sit down so I did, Max kept his feet in my space all during lunch and my knees were practically on top of his, lunch was plesant and the conversation wasnt out of the ordinary, Max left after 45 mintes to return to work, he had been spending time with John in the city as they dont see each other often as they live in different cities hence why Max was here today, at one point during lunch max mentioned his feet were aching and he was looking for a good massage place to massage his feet while staring directly at me, I was turned on and started fantasisng then and there about worshipping and kissing his big sweaty meaty alpha soles, Max had to leave and as John and Max said goodbye he gestured for me to fetch his coat which I did and helped him put it on, he said it was ''nice to meet you boy'' and grabbed his briefcase outta my arms and was off, John and I spent another hour chatting and having lunch but my mind was fixated on his dad Max, I felt and still do feel so guilty but he turned me on and exerted dominance over me, my question sam is what do I do next? how do I approach Max about servitude and being his slave/Fag? I really want to serve him but dont know how or what to do next, please help, kind regards-Kule, Thanks
