When an alpha feels inadequate in their role, it causes a biological effect called bitching. Bitching causes an alpha to gradually lose control over their forcibly relaxed abs and legs the more they're humiliated. The arms, head, and back muscles of the bitched alpha remain usable, but they're completely helpless to stop anyone from breeding their brains out. The fluttery feeling of the affected muscles ignoring impulses is insidiously addictive, and after being fully bitched(i.e. paralyzed completely by submission), disobedience becomes impossible for the bitched alpha, unable to do anything but chase the sensation of forced helplessness over and over again. Alphas, even when bitched are incapable of producing slick. Having a retinue of bitched rivals is a powerful social statement for alphas, and even tenacious members of other genders (omegas and betas) E-bitchers are an illegal weapon that forcibly relaxes an alpha's muscles, forcing them straight into a completely bitched state that their body conserves for over an hour, plenty of time to irrevocably break any alpha's will.
