I remember when the first Maria build dropped and the forum went absolutely feral over the nun corruption angle. This second edition though, they went straight for the backdoor and honestly I respect the commitment to the bit. The whole thing is deliberately rough around the edges, that work in progress feel where some transitions just sort of happen without much grace, but the anal expansion pack is where they clearly spent their energy.
The internal anal cumshot option is weirdly specific and I spent way too long cycling through it just to watch the aftermath animation. There's this moment where Maria's expression shifts, not dramatically, but enough that you catch it if you're paying attention. The sweating system they added is subtle, like someone actually thought about how skin would look after getting absolutely railed. Her ass bouncing has this rhythm that breaks occasionally, which sounds like a complaint but it's not, it makes the whole thing feel less like a sterile animation loop and more like actual messy sex. The pussy pulsing after she squirts is a nice touch, though the squirting itself goes a bit overboard, like someone turned the particle effects slider to maximum and forgot to dial it back.
The body swaying during anal penetration is where I got distracted though. There's this slight lag sometimes between the thrust and her reaction, a half second delay that I can't unsee now. It's the kind of thing that'll probably get smoothed out in later builds but for now it lives rent free in my head. The pussy licking option feels almost like an afterthought compared to how much attention the anal stuff got, which makes sense given this is literally called the anal expansion pack. I wish they'd added more variety to the undressing sequence instead of just the one way it plays out, but I get that's not what anyone's downloading this for. The sound effects are fine, nothing groundbreaking, the wet noises during the ass licking scene are actually better than the penetration sounds which is backwards from how these things usually go.
