I know this probably isn't going to be updated, but I figured I'd put this out there nonetheless. I had a lot of fun with this game, but there are a couple of ways I can think of improving it. First of all, you can get absurd amounts of value and Scales if you just make trades with one person repeatedly for the purpose of increasing relationship, then buy all your stuff back with a singular Sex transaction because all the useless trades you did raised relationship so much. I think a change to the way that Sex specifically is valued would probably make this a lot more fair. Or maybe make it so that sex value is increased by having sex more, and have the relationship stat let them... stock more goods or something? Secondly, I love the fact that the characters strip, but the fact that they do it only once, on the second stage and never again is a bit disappointing, since Lizbeth and Tanya both remain partially clothed through the whole 10 bukakkes. You could've made Samara have panties and have all three strip their lower-body clothes at Sex 4 or something like that, which I think would have made it a lot better. Third, a minor error, I noticed that in Tanya's bukakke images, she gets a larger glob of cum dripping from her mouth, but it immediately goes back to what it was before on the next sex.
Also, I really like how the character props like Samara's bottle and Lizbeth's basket get gradually filled up with cum as you have sex with them. And all the bukakke image progressions look good and really natural, although except for the fact that the boobs usually got covered from the bottom-up in most cases.
Even if you don't update this game, I'd love to see another game with a similar concept, either in the vein of item-trading or in the vein of progressive bukakke/stripping sequences.
