These are both hidden away in the scene where Sami finds you hiding panties. For this you will need to go one a quest to find panties (Haily can send you some). I would be less specific but currently the scene only has that one opening.
See, this is why this game is absolutely amazing and I truly am in awe of what you've done here. I've spent A LOT of time on this game, and have never come across a quest for panties. So much to find and uncover, and you can go as shallow or deep as you want and be entertained. Kudos!
