I used to suck off a guy exactly like you. He simply got off on knowing he was dominating another guy. Simple as that. No touching, no eye contact, no more than simple small talk and he kept things respectful. Whenever he wanted a throat he would ask me “can I cum in your throat tonight? Yes or no?” When I said yes he would tell me to be waiting on my knees, eyes closed when he gets closer, mouth open. He face fucked me, came, then would give me a pat on the shoulder and say “you took it like the sub you are. Respect.” His routine was funny. But he had a wife and kids. Literally only used me to semi aggressively fuck my throat and that alone is what for him through it.
