For context, this isn't actually a real couple. He's more of a glorified simp for her who she keeps "maybe"ing into sticking around, bringing pizza over to us when we hook up, and occasionally help prepare her for her "date" with me. Let's call her F.

Recently, in the heat of the moment, F started getting close to cumming and making him admit all kinds of things to her, including that he would even swallow a load from me in order to prove his devotion to her and for a chance to maybe get to touch her intimately one day (probably never sex, though).

Well, that was all the permission she needed. Since then, F has consistently either snowballed my load into his mouth or popped a squat over his face and squeezed it out. She even asked me to start taking supplements to increase my load size. She also always does this thing where she implies that this time is probably the last time she'll make him do it, because it's starting to bore her, but then the very next time I come close to orgasm, without fail, she summons his open mouth over to us and his face scrunches up and bites the bullet.

However, a few days ago, the cuckold spoke privately to me while she attended to the bathroom and asked me to "chill out" with feeding him so much "stuff" all the time (lol I don't think he could bring himself to admit aloud that it was cum he was eating). I told him I'm not the one choosing where to cum, as F keeps popping my dick out of her holes as soon as I'm about to cum and then she calls him over to position it over his face. I also told him that it kind of wasn't my problem because I have heard him answer her every single time she asks if he'd mind if she "needs something from him later". Whenever wifey says she might "need something later" and is "counting on him", nobody says it aloud, but I am 100% positive that all three of us know that that exact phrasing means "I might need to empty OP's load in your mouth later, do you mind?"

Anyway, we all met again yesterday and I told her his concern. I suggested that it might be nice to cum elsewhere for a change. She asked me why I said that. I said that maybe this cuck would prefer it elsewhere if at all. I don't know him that well yet, otherwise I would be more comfortable in dismissing his requests. However, he wasn't dating her anyway, so I thought it would be fine to indulge them and tell her what he wanted.

His response was so surprising. Instead of thanking me, he actually got angry at me for revealing his concern. He flat out denied having said anything like that and said I must have "misheard something, like always". However, even F has informed me that she thinks this isn't true, since he can't seem to remember what we really were talking about if not about him not wanting to eat my cum.

The loser was literally asking my help in putting a stop to the practice without having gone to ask her on his own. I had no obligation to help his irritating ass and I still told her what I did. I'm pissed about it, and I may even want to take it out a bit on him or on F, the subject of his affections. But I'm going to wait for you guys to weigh in first before I decide on what to do.

As an aside, there is a small possibility that I can talk to wifey and get her to impose some new rules and restrictions on him. I don't know if that would be relevant or helpful at all.

We are at the house again today and he will be buying dinner for us. He'll probably be here by the evening (it is currently 9:34am central time), so we have several hours at least.

So... AITA? I really do not think I am the asshole in this situation.

TL;DR - Woman keeps feeding my semen to a cuck who asked me to help him get her off his back; when I tried to help, he got angry at me for giving too much away (at least that's part of the impression I got from him).
