Guys, its pretty clear the reason the "voice acting" sounds like that its because its not voice acting. Its real porn audio. Of what video? Who the hell knows, but its sure as hell just a real video's audio being played over the animation.
Yeah, the voice acting sucked. I've seen that more and more, futas being voiced by men pretending to be women. But I guess that's the same as many futas not being actual futas (who are supposed to have both pussy and cock) and instead being shemales (cock only). Like in this clip. Kind of surprised they didn't pair the shemale with a man. But give it time and the artist will likely gravitate towards that.
Horrible choices for the voice actors and why did she-hulk start sounding like a man after they started fucking? No lip-syncing for all the stuff black widow says while she's getting fucked either. The models look nice but I'd bet those were stolen.
The only thing missing was cum gushing out at the end.
