Unexpected Connection at the Beer Festival

Part 1. Beer Fest. Recently, had went to beer festival located in San Antonio, Texas. I am not a big drinker, but being in the business it's good to mingle. Was talking to a group of friends and a guy I have never met, Alan, was there with his girlfriend who was not enjoying herself. Complaining about the weather, dust and such. She was just miserable. Felt for her. He was a bit intoxicated and did not pay much to her concerns. Which I don't agree with but kept my opinions to myself. After a bit they walked away from the group and went off to the side to talk. Alan approaches later and says she left and that was his ride, but he did not want to leave and wanted to stay longer. Told his buddy he would just get a ride later.
He started up a conversation with me about my time in the service industry and was surprised that I don't drink much. He laughed in a good way and said he does not have that type of self control. As the day went we all made the rounds to each of the exhibition booths and had some good conversations. After 6 hours of being there I began to excuse myself saying I would be leaving and said my goodbyes. Alan approached me and asks what part of town I live and he stated he was not far from me. Asked if he could catch a ride with me. I said sure. We get to my car and I put his address in the GPS. He joked saying he maybe locked out of his own house when he gets home, he tried calling his girlfriend. They live together, and he wanted to tell her he was on his way home. I said if he wanted to go anywhere else, just let me know. Not going to just drive off if he is stuck outside. He asked if my 'girlfriend' allowed me to stay out without her. I stated that I am single and gay. He made a slight sigh. I commented saying that if he was uncomfortable being around me, I would just drop him off and no bad feelings. He laughed and said no, he was actually 'bi' and his GF did not know. I said ok. We get to his place and she is not there. Her car is not parked out front. He tries calling her again from the car and no answer. He asks if I want to come in for a shot of liquor which I declined. "I am driving my man." I reply. He said ok. "Well, want to see my beer glass collection?" I replied "Sure". Just wanted to leave and get home. We walk in and this guys house is nice. Clean and organized. He walks to his fridge and pulls out a beer and asks if I wanted anything, I request a glass of water. He has a large cabinet with not only glassware but beer steins as well and other items. He stated she does not like the collection but it's his house and it was there long before her. As he is telling me about the collection, he rubs his crotch at various moments. Noticing that his cock is growing slowly. After a bit and he is done with the 'tour'. His cock has now became very obvious. I can tell he is a little nervous in his speech. "Well, time to go man. Hate to intrude on your time and enjoyed getting to know you." I say. I give him my business card with my number and say call sometime and we can hang out if his chick does not 'kill him', jokingly. "I enjoyed meeting you. Don't worry about her. She will get over it. I will sleep in the extra room for a couple nights probably and then it will be ok." He responds. "I hope they bed is comfortable." I say with a smile.
He looses his train of thought with his words and says "You want to check it out?" I say "yes" as I put my had on his shoulder. He begins to shake a little with nerves. As he walks in front of me to the room, my hand on his right shoulder. We walk in a bedroom. Curtains closed Bed made. I question "Are you ok Alan?" He responds mumbling in his voice "Yes. I am". I lower my hand to his lower back and slide my hand below his beltline. He turns around to face me and puts his hand on my hips and pulls me to him. Continue to part 2. Beer Fest.
