Understanding, you not in acceptance to Dave's request and you put your hands to Dave's shoulders and help him sink further into the canvas. It's interesting to you to see what what happened to you yesterday from the other perspective, it makes you giggle a bit as you watch Dave sink in and turn into a painting of himself.
Dave takes a sudden breath as he feels his thighs and chest sink into the blank canvas and flatten into a picture, the increasing tingling sensation and enjoyment that overtook you starting to affect him as he sinks further and further in. Dave's pants are slowly pitching a tent as he feels his chest, thighs and shoulders sink in and turn into a picture. He audibly gasps in pleasure as he feels his manhood make contact with the magic canvas and gets sucked in tip first, and he quivers a bit as unlike you he's already dripping pre-cum half-way sunk into the canvas.
You smile and giggle at Dave's predicament knowing full well what it felt like when you were turned into a picture and what Dave is feeling right now. You give Dave's shoulders another push and the magic canvas gives way to accommodate them, and watch in glee as a moaning Dave is sucked into 2D. Dave tries to struggle against the canvas, not out of any desire to not get sucked in, but to try to enjoy the experience a little more as he's more than two-thirds a still picture, with only his ass, head, hands, lower torso and pelvis not fully absorbed into the canvas. Dave twitches in enjoyment as the canvas suckles on his groin, his cock already turned 2D and unable to orgasm no matter how much Dave feels the need to cum.
His face makes contact with the canvas next, allowing it to quickly absorb his head turning it into a part of the picture. You then move your hands to Dave's rear, having only this one last chance to fondle him before that to is flattened into a picture. Dave's rear quivers to your touch as you grope him and it slowly sinks in. Now being the last thing left of Dave that is still 3D, you give it a push and his ass sinks into the painting, leaving nothing left of Dave in the real world.
You step back a bit and admire the painting. It's strange to think that you looked like that only a few minutes ago yourself. Perspective really is a huge difference.
After a few moments, the picture of Dave re-animates as Dave seems to recoil from his orgasmic planar transportation, but then again, you already know what that was like, and a part of you envy's Dave who is just now getting his first experience becoming a painting. The portrait of Dave then turns around slowly and you can see his mouth is agape in awe. You then watch him visually speak the word "Wow!" followed by more words, but you can't really make out what he's saying inside the painting. Then again, Dave couldn't hear you when you were inside there, so it was expected that you can't hear him now that he's inside the picture and your in the real world.
You giggle to yourself and even wince when Dave starts to explore his new 2D form with his hands. He seems completely blown away by his experience being a animated picture. After Dave is done confirming he is completely without depth, he motions for you to come over. After a short breath, you approach the picture and place your hand on it.
"Okay, okay, wow... Erin, you weren't kidding about how great it feels being in here... Just... wow... I feel relaxed like I just had the orgasm of a lifetime but I'm still buzzing like I'm still cumming but with my entire body... You were right, it is an intense experience..." the painting of Dave says.
"I told you~ So what do you want me to do now? You said you wanted to try some things after you get sucked in and you're sucked in alright! To be honest, I wouldn't have minded it if you had left me inside there permanently." You reply.
"Yeah, no kidding... This is such a surreal and deeply sexual feeling... I can't believe this is what you felt after being turned 2D... I really could stay in here all day... This feeling is truly amazing..." Dave says looking into your eyes.
"You know seeing you in 2D is turning me on... You don't need to remind me what it was like being stuck as a painting... I loved being in there and a part of me really wants to go back..." You reply, but Dave then cuts you off saying, "W-w-we'll get to that... Anyway Erin, here's what I wanted you to try doing to me... There's some things we never tried while you were inside the painting. I want to try doing those things to me."
"Like what? I'll do anything you ask of me!" You reply.
"Well, for one I want you to try erasing a part of me. Just a small part though, like my hand... Then I want you to re-draw it back onto me. If it works, it will be like my hand was never erased in the first place." Dave states.
You pause for a moment a bit shocked. "You... you want me to erase you? Why? Isn't that kind of dangerous to be try?" You reply worried.
"Like I said, I want to know what happens, then just paint me a new hand. I painted you a new body, so I should be fine." Dave reassures me.
"Yeah, but, you painted over my old body... It wasn't like you were trying to erase me..." You say still worried.
"That's why were trying it with just my hand first. Go ahead Erin. I'll be okay." Dave says with a sure look on his face.
You take your hand off of the painting and step back. You haven't even gotten a chance to check out your strangely rubbery, toon-like french maid outfit and body yet and Dave is wanting you to try erasing a part of him. You think about if you should really try doing what he asked or if perhaps you should try doing something else while Dave is stuck as a painting.
