Also, why not add the option to ask for a creampie if its your first time with them?
If I remember correctly (been doing other things), that's not an option because it's story driven. A lot of the love interest weren't on contraceptives (because, not sexually active. or was it just Laura. Someone correct me if I'm wrong) until you two go official.
Basically, the 3 starting love interest all have trust issues (for good reasons) and they're not about to cum inside them until they can trust you.
- Lewding with clothing - being able to fool around with skirts flipped up or holes in the girl's tights would be great, its a rather broad fetish so I think it would be a great addition.
Holes in tights means extra art assets. Which, I believe is their current bottleneck. They have other priorities at the moment like getting Kitty, Dazzler, Storm and Emma drawn.
As for skirts flipped up...
It's limited, but it is possible. Now, can you get them to walk around like that? No. Unless you're cheating (which, I know you are).
Just keep in mind that it is subverting the game's logic so it can get a little tricky to get them to do it. Also, you need A LOT and I mean
A LOT of love and/or trust.
