I saw a wordless comic of two versions of Roll (I'm pretty sure they were the Rolls pictured here) and I'll describe what happened in it:

-Roll 1 suggests that they should exchange clothes, for fun.

-Roll 2 thinks it's a good idea, and we see her putting on Roll 1's clothes.

-Roll 1 is shown offering Roll 2 her panties, as if to say "here, you put on my panties, too!" This shocks Roll 2, who clearly didn't think they would be exchanging underwear also.

Again, this was wordless, expressed by movement and icons. Also, I think the comic was part of a series, where the artist made the two Rolls play a lot with each other, but one of them was always a bit naughty and teased the other.

Anyone has it? Thanks.
