Alpha sperm possibly??

I think I met someone who has an Alpha sperm. Now I’ll explain, I met a man in a grinder, he’s 52 years old, an average body for a mature man, his penis is about 18 cm. He lives alone with his cat. So our meetings are the same. I come, undress and get on my knees, suck his dick, he fucks me in the mouth and all that.. then when he cums I naturally swallow everything, and then I leave.. that’s all. nothing unusual, BUT... I'm starting to think about sucking him even faster than usual, unlike when I meet others and suck them off. Every load that i swallow makes me want more. I don’t know what exactly is happening, but it seems to me that his sperm somehow affects me. It’s possible because it’s ALPHA sperm and it’s addictive to me.
I don’t know, but this has never happened to me before. unfortunately, he doesn’t write to me very often, sometimes he simply ignores my messages, but I can’t be angry because I made it clear that I’m his bitch and I can only wait for an order from him.. but when he writes to me, my useless dick is starts to leak just because I'm going to suck him.
Also, when I'm horny and I think about sucking some Alpha dick I got really hard, but when I'm at his place, kneeled... my penis is shrinking and turning tiny. And then it’s immediately clear who is the Alpha male and who is the pathetic fag-got, cocksucker.
I will be glad to hear your opinion about this, maybe someone has already had a similar experience, share your experience.
