I'm not certain if this is entirely intended, but I don't think this was supposed to happen for either of the two scenes. Decided to see if impregnating Feruze was based on chance; and as it turns out, fucking Feruze on that encounter doesn't remove the Rut status effect. Coincidentally, this also happens to be the case for the Nastizia quest on Tavros on the final fuck, which you get after defeating the Shock Hopper.
So either both of these hoes are lying to Steele and got impregnated by somebody else before-hand, or the game doesn't actually check for virility and just lets plot be plot.
