and again a take on Sebastian's Happy Sack idea ^^
But this is not a normal Happy Sack this one is a "Happy PET Sack" the only real difference is that it looks like a pet, which makes it for some more appealing to look at and/or to try it on.
Also I added a means to get the suit off again. In that small thing beside the box is a zipper shrink-wrapped. If you put this zipper anywere on the sack you can zip it open and if you want also close it again.
Sure that only works for the one inside the Sack if he/she remembered to take the ziper inside and if he/she can ignore the Happyness for a moment.
Well in the case of Kas she did not remember (or did not know) to take the zipper inside so someone would need to free her from the magic sack.
I drawn this because of

who wrote a stroy about Kas and her Happy Sack.
The story would need here and there some changes and the Sack in the story is a normal Happy Sack but he thinks about to rewrite the story.
And here is the story:
Finding Happiness
by ~Dr-Golgoth
Kas sat in her apartment, completely alone, her legs drawn close with her arms folded around her knees. After being bimbofied, covered in brain slugs, hypnotized and dressed as a Ducklett, caught by a Chandelure and made to do things she still couldn't forget about (not that she really wanted to), not to mention that ordeal dressed as a witch, she was more than a little worn out, and couldn't fully describe the emotion she was feeling. Was it boredom, or was she stressed out? Maybe she was just depressed... At any rate, she didn't want to keep feeling it. There was usually something highly traumatic and sexual happening to her that would distract her from any of her own emotions, but now that she had time to relax she found she didn't like being left to herself. Despite everything that had been happening to her, she desperately wished that something new would happen. "Please," she muttered out loud. "Anything."
Then she heard a knock on the door. She perked up, surprised by the immediate answer to her plea, and hopped up to go answer the door. She felt her foot come in contact with something sticky and soft as she walked, and used as much of her willpower as she could to resist the sudden feeling of numbness and sexual pleasure as she kicked the stray Brain slug to the side and continued to the door. She shook her head, exasperated, wishing there was a way to get those slugs out of her apparentment without touching them. She'd tried, but one way or another the slugs always got to her brain and made her masturbate while they fed off of her thoughts.
She opened the door, and was met by a medium hieght, attractive blonde dressed in a bussiness suit and holding some sort of package. "Uh, hi," Kas greeting, not sure what this was about and trying not to appreciate the other woman's bust, or how the suit revealed her cleavage. "Hello," the other woman responded cheerfully, bouncing on her feet so her breasts gave a nice little jiggle that Kas couldn't help but notice. "I'm May, I work at Sebastian Inc. and I'm here to deliver your free Happysack!"
"A Happy... sack?" Kas asked confusedly, trying to make eye contact while repeatedly glancing at May's breasts. "Yeah, a Happysack! See, Sebastian Inc. is developing them, and as a promotional event we've been giving a few models out by lottery, letting girls try them on, see how they feel, give us a review, stuff like that!" She bounced on her feet a few more times, happily smiling as he breasts jiggled to earn Kas's rapt attention again.
"Okay..." Kas responded slowly, getting the gist of what May was saying, though openly gazing at May's bust. "So... What's a Happysack?"
Bouncing several times as she did, May lifted the package and held it towards Kas, who accepted slowly and glanced down at the package curiously, then started to stare as she saw the label. Under the broad, colorful words 'Happysack', the was a picture of a young girl, completely naked inside of a transparent bodybag sort of thing. She was curled up suggestively with her hands positioned on her crotch, wearing a broad, sincere smile on her face. Kas glanced back up at May, who stood there still smiling broadly as if none of this was unusual. "You see," May began, "The Happysack allows women to relax and unwind while shutting out outisde influences, and it produces a series of endorphins and chemicals that actually trigger happiness in the brain, hence the name." She giggled, as if she herself hadn't understood the explanation. Kas didn't feel any more enlightened as to what the Happysack actually was, but the picture on the label seemed promising, since she found herself glancing at it more often than she was May's bust.
"So," May said, "Can I come in? I'll help you... try it on." The last part sounded almost suggestive to Kas, but it was probably just the aftereffects of being Bimbofied messing with her head. Regardless, Kas eagerly nodded, backing up and letting May bounce her way in, closing the door behind her.
"Alright!" May said, skipping arround the room as Kas watched. "Let's find a comfortable place to let you put it on... You'll have to be naked, by the way."
Kas perked up, following May towards the couch and looking at the other girl expectantly. "'Kay," said the blonde, taking the package from Kas and opening it. "Go ahead and take those off while I get this ready..." Kas eagerly tore of her shirt and bra, letting her breasts bounce freely as she leaned over to pull down her shorts and panties. She felt her pussy getting damp being naked in the presence of another woman, and it was no wonder why she was aroused, she would get this way around practically anyone after everything she'd been put through. Though, recently she had noticed herself being more drawn to women like herself instead of the men she'd liked before...
"We're ready!" Kas was jolted from her thoughts and looked up at May, who was now holding a strange pink bag made of some sort of rubber-like material. "If you'll get down on the couch, I'll help you slip this on!" Kas quickly did as she was directed, laying down, then spreading her legs wide apart. Force of habit.
"You'll need those a little closer together," May said, not once breaking from her usual smile. Rather disappointed, Kas put her legs together, blushing slightly. May knelt down at the foot of the couch, Happysack in hand, and started sliding the bag over Kas's feet. Instantly, Kas's arrousal doubled, her pussy juices dripping on the couch as a strange sensation from the sack shot up her leg and went to the spot between her thighs. Kas had to hold back a gasp as she felt the sack begin to slide up her legs, brushing brightly as she was made all too aware of her arousal. "Is-Ah! I-is this-Ah!" Kas struggled to speak between short moans, jolting as her pussy was assaulted with new sensations every time the Sack slipped an inch up her legs.
"It's okay, your body is supposed to react this way!" May explained happily, forcing the Happysack up to Kas's thighs. She paused and reached up to clasp each of Kas's hands, humming cheerfully as she guided them to the spot they were needed most. Kas's eyes widened as she watched the blonde move her hands down to her pussy, placing them there and withdrawing her own so she could force the sack up past Kas's waist, trapping the arroused girl's hands right on to of her sopping wet cunt. Kas had been using every bit of resistance she had not to take her hands and fuck herself to oblivion, and now that May had trapped both of her eager hands right where they most wanted to be, her 'resistance' pulled a vanishing act. She didn't care that May was right there, she didn't care where she was, she didn't care who she was. All she knew anymore was that her pussy wanted to be fucked, and it was going to be fucked right now.
Kas's hands began their work, rapidly massaging her wet pussy as May merrily continued to slide the Happysack further up Kas's body. Kas was moaning loudly now, her hips bucking with every movement, and her hands becoming more forceful in their efforts as her arousal doubled and tripled. This wasn't like anything she had ever felt before, and she loved it with every once of her being. It was like most of her brain had just taken a vacation, and all of her mind that remained was wholeheartedly focused on her sex. Her vagina was the center of her existence right now, and she worshiped it wholehearted, her hands thrusting against it as her fingers made their way even deeper inside, ramming into her core and soliciting blissful moans. She didn't know who she was anymore, and she didn't care in the slightest, she was being fucked, and that was all that mattered.
"Almost done," May chirped, coaxing the suit over the convulsing girl's bouncing breasts. She was sitting on top of Kas's chest, her legs wrapped around the other girl sensually as she moved the Happysack over Kas's shoulders. She'd been sure not to respond to Kas's attemps earlier, but in all honesty, May was enjoying her job WAY too much, she wasn't hiding it anymore. Her cheeks were deeply blushed, her eyes half closed in arousal, and her pussy was sopping wet through her clothes. Knowing that her job was almost done, May figured she could have a little fun, and so she gave into her lust, just for now.
Lifting her skirt up so it didn't obstruct her pussy from it's goal, May lowered herself onto Kas, rubbing her arousal directly against the Happysack and moaning loudly. Kas was completely unaware of her surroundings and paid no heed to May, thrusting her fingers deep inside of her and moaning as she had before. Her eyes were open, but they were completely glazed over and stared past the other woman, not processing or understanding anything they saw. May was now very busy with her new job, her wet pussy gliding back and forth against Kas's Happysack, her brain picking up on some of the aphrodisiacs the sack was soaked with. She still wore her usual smile, but it expressed more than happiness now, it shone with arrousal.
As she continued to grind eagerly against Kas, May reached up to her bouncing breasts and slowly undid the buttons holding them inside of her shirt. Tearing open the clothing, her hands gripped her breasts tightly, slowly massaging and pulling them. Soon she had a nipple in between her finger and thumb, and began to squeeze and rub it eagerly as she did the same with her other hand. For the first time since she'd entered the room, May broke her smile and let loose a load moan, harmonizing with the oversexed Kas underneath her. Now the both of them were moaning loadly, and while Kas had already came several times, she had not eased up her efforts on her cum-covered pussy.
After a few more minutes of thrusting, grinding, and squirting milk from her bulging boobs, May came, squealing with pure pleasure and soaking Kas's Happysack with even more cum. Once she had recovered, May reached down and pulled the hood over Kas's head, earning a load, yet muffled squeal from the Happysacked girl. May grinned. The Happysack was built to repurpose women, in a sense. Once Sacked, a girl lost most of her brain's functions, and her body was made to do only one thing- Pleasure itself. The bag itself provided the nutrients and oxygen necessary to keep the girl alive, but it didn't take much. The brain hardly needed any oxygen to function, and the body required minimal energy to power the hands, which became the only moving parts after a few days. May stood up and hopped off the couch, not bothering to clean up Kas any as she went about tidying herself up. The Happysack was designed to absorb female ejaculates, of course, so she didn't need to worry about removing any... evidence of her little joyride. As soon as she cleaned herself up, she'd call some workers at Sebastian Inc. to come pick up Kas and move her back to the company building. She had a feeling Kas would make a perfect display model for the Happysack...
As May made her way to the bathroom to pick up a towel and clean herself up, her foot came in touch with something soft and sticky. She tripped and fell of the ground, but as she was about to pick herself up, for the second time since she'd entered the room, she stopped smiling. Then she stopped thinking. The Brainslug on her foot had now firmly attached itself, completely sapping May's brainpower and replacing it with only one order, which she hastened to obey.
As May yanked off her suit, pulled her panties completely off, and began fucking herself on the floor, Kas was thrusting into herself even faster than she had before. Faintly, her body noticed it could no longer breathe, but it didn't concern her at all as her fingers pistoned in and out of her vagina. The lack of oxygen in her brain actually added to her arousal, taking it to heights it had never reached before. She squealed and moaned through the rubber covering her as her orgasm began, exploding inside of her and wiping her brain empty once again. She moaned loadly, bucking and humping the couch for several minutes as the orgasm blew her mind again.
As she began to settle down again, her mind was hit by a new wave of sensation, one that was becoming a norm while in the Happysack. She smiled broadly, her eyes wide but unseeing, smiling serenely as she started fucking herself all over again. She couldn't think anymore, but it didn't matter. As long as she was inside her Happysack, nothing mattered. As long as she kept fucking herself, she would be happy. Happy, happy, happy....
