The thing is that I think orgasm denial and multiple orgasms/overstimulation are both very much a part of Shane and Ilya's sex lives. It comes down to the fact that I very much see Ilya as a pleasure top. So, like, I think Ilya's initial instinct when they start being able to spend days on end together is to literally suck that boy dry and then pound him into the mattress until he's crying and begging for mercy. Lather rinse and repeat until Shane is so fucked out that no coherent thought could exist within him. But I also think orgasm delay and denial is so deeply satisfying to Shane and Ilya has come to love it because he knows that, ultimately, it feeds something within Shane's soul to be made to hold off, to control himself even when it feels like he could go wild with it. Plus, Ilya just finds it really hot to tell him no, especially when Shane is dying with need and trying so hard to be good for him.
In any case, what I know for certain is that the decision of when, where, and how often Shane comes is entirely Ilya's decision. At this point, any orgasm that wasn't a response to Ilya explicitly demanding it would taste hollow and wrong.
