I’m a straight guy who fucked his Asian friend / landlord. Idk how to stop.

Don is my friend and occasional gym buddy. We have a lot of mutual friends. He is Asian, in his mid 20’s, black hair, fit. I’m white, just entered my 30’s, kinda fit but taller than him (sorry I suck at descriptions). My friends warned me it’s probably not a good idea to move in with Don because A) I should just buy my own place since I can afford it and B) because Don is single and everyone suspects him to be gay, even though he hasn’t told anyone. He just doesn’t share anything about it. Against their advice I took the risk. Few months everything went smoothly. Nothing g out of the ordinary. Things changed tho when I came home one day and Don had another guy over apparently because I could hear that guy absolutely fucking the daylights out of Don. I didn’t need to physically see it. Sound and words were enough and it was clear that Don was getting fucked by what was being said by both. My leaving made just enough noise apparently for them to figure out that they had been caught, because driving to a local coffee shop to wait it out, I got repeated called from Don. In a panicked and confused state, I didn’t answer them. Don just blew up my texts with “please don’t tell anyone”, “please pick up the phone”, “we need to talk PLEASE”. I called him back a bit later and told him I’d be home soon. When I got home, Don had clearly been crying and was distraught and ambushed me as soon as I came in. I heard him out and his pleas to keep quiet because his family would disown him. They don’t know. I told him it’s none of my business and I would never. I promised him I would keep it a secret. He hugged me and knowing he had been fucked just an hour ago made me kinda turned on. I just let him hug me. As time went on we talked about it, he came out and told me everything over time and said it was good to finally tell someone he is friends with. That’s cool! But this is where things started to get murky. The more he told me, the more comfortable he got with me. He started wearing less clothes around the house. Talking to me about gay sex and dating. And started to compliment me, a lot. All of this led up to a night where we both got wasted and one thing led to another. Don asked me if I had ever thought about men, I lied and said not really. Don paid compliments to me and my bulge and told me how amazing gay sex can be and then told me he would love to show me. To thank me for being a good friend and keeping his secret. My curiosity and alcohol consumption and disregard to friend’s advice led me here: I let Don suck my cock that night. He pulled down my sweats, got me hard, sucked on my cock, sucked on my balls, slapped his face with my cock, and deepthroated me until I came. He swallowed it all. I can’t even begin to convey how friend my brain was after this with pleasure. Don had corrupted my brain. I couldn’t stop thinking about it after that. I eventually let him suck me a few times a week. I kept telling myself it’s just two guys helping each other out. Nothing gay here. The boiling point came when Don made the next move: he came to my room one night, lights off, and whispered asking if I was still sleeping. I said no and he quietly crawled into my bed. He was clearly naked which kinda made me tense up until I felt a jockstrap on him. I thought he was gonna suck my cock again until he climbed onto my lap under the sheets and we were face to face. I sleep naked and I got hard really fast. Don just whimpered that “I can’t sleep, I need you to give me your cock.”My brain took a minute to register what he wanted but the warm wet hole swallowing my cock made it clearly quickly: Don wanted me to fuck his ass. I just laid there and let him do what he wanted with me. He sat fully into my lap and took my big dick inside him and sighed in relief. I lasted like 10 minutes maybe with him slowly riding up and down and saying “you like that? You like Asian pussy? You gonna cum inside me?”It felt like I was dreaming. I came inside him so fucking hard that I felt like my balls were gonna shoot out of my dick too. He stayed seated in my lap and stroked himself to finish with me inside him. I got to feel a dudes ass spasm and clamp on my cock for the first time ever too. Fucking awesome!!!He got up and I slipped out, zero cum came out of him. He went back to his bed while saying “thank you”. It’s been almost 2 months of this and I haven’t told anyone. It’s the biggest weight on my shoulder and chest and I feel like I’m living a double life. I can’t stop fucking and breeding Don. We have sex like 4-6 times a week if not more. I work like 60 hrs a week and all I’ve been doing is work, eating, gym, sleeping and fucking Don. His parents came to town to visit and he recently got the “you need to find a wife already” talk and I had to overhear him appease them and defend himself. All while hiding the secret that their son got railed by me the night before and he has another dudes cum and DNA inside him. This is SO FUCKED UP that I can’t think straight at times. Welcome to my fucked up existence guys.
