After just deciding to be better, he doesn't give himself much choice.

James swallowed, his mouth suddenly feeling dry. Going out. Alright. He could do this. Managing a shaky smile, he looked up at his sister.

"Sure, let's go to Baxter's," James said, getting up as he held the squealing Lily by the butt cheeks to keep her from falling. The blonde giggled, holding onto his shoulders with both hands, and gave James another quick kiss, smiling at him.

"Thanks, Jay. I really need to get out of the house, or else I'll get cabin fever. And I'm starving!" Looking down to where the step-siblings' tits were mashed together, Lily pulled a face. "But first, I need some extra layers to hide the twin-- no, the siblings? Whatever. How about you? Think you'll be alright?"

Setting Lily down, James looked down his front. Thankfully, his father's shirt was baggy enough to conceil his lower breasts, hanging from the top row as it did. Still, a bit more protection would be nice. As it was, he was one gust of wind to his front away from getting found out. But considering Lily was a few cup sizes ahead of him, she had to have a plan, right? When James asked her as much, his sister smiled.

"Easy: I have a few really tight tube tops. Put on one or two on under the shirt, and boom! What used to be tits is now a slightly pudgy belly. At least, I hope so. If not, we have bandages somewhere, but that'll be really uncomfortable, I think."

"Seems like you thought this through, then." James replied.

"Not really, it's just an idea so far. Want to try if it works?"

Indeed he did. After putting away the remains of their failed breakfast, the two dog morphs went upstairs into Lily's room. The blonde dug out her tube tops and laid them out on her bed, standing over them with her hands on her hips.

"Alright, that's all the ones I have," Lily said, beginning to pull her shirt over her head. James turned away, his face suddenly feeling very hot.

"What are you doing?" his sister laughed, continuing to undress. "It's nothing you haven't seen before, right? C'mon, you need to try one too, if you don't want your tits hanging out!"

James had to admit the blonde was right. But somehow, without the haze of lust clouding his mind, it was incredibly embarrassing to see Lily half-naked. Or even worse, get undressed himself. His sister obviously had no such reservations, throwing her shirt on the floor, three magnificent rows of soft, jiggling breasts on full display. Lily's nipples crinkled and stiffened in the air controlled room, and James suddenly found it very hard to think. Jaw hanging slack, he watched as the pendulous orbs swung around while Lily bent forwards and picked through her tops, blood rushing down into his groin. They were so big, and soft, and there were six of them, lightly slapping into each other with Lily's every move...

Already James bestial cock was poking out of its sheath, the knot swelling and stretching out his skin and pants. But as he made the first step forwards, hand rising to touch his sister, Lily straightened, one tube top in every hand, pushing one in James' hand, keeping the other for herself. With his mental processes not exactly at peak effectiveness, James grabbed it and stared down at the fabric, like he wasn't quite sure what to do with it, making his sister giggle.

"Put it on, silly," she smiled, getting to work on her own. James couldn't suppress a tiny sigh as her magnificent tits disappeared under the thin fabric; but at least Lily's trick seemed to work. While her stomach bulged weirdly, it didn't look like extra tits - just one or two pounds to much on the belly. Lily poked her lower breasts with one finger and grinned at her brother.

"Am I good or what?" Her face fell a little as she saw James standing there, making no move to get himself dressed. "Come on, put it on, I'm hungreee~!"

"Oh! Uh, yeah..." James turned even redder and pulled the oversized shirt over his head, tossing it on the bed. Putting on the tube top, he had to stretch it a bit, but managed to put it around his mid-section - since he was a fair bit taller than his sister, it only covered his middle and lower row of tits, flattening them against his abs. It looked more like a belly band and would never fit Lily again, but at least his extra tits were covered, and with his shirt back on, James looked completely normal. Lily had put on her own shirt back on, now looking completely normal, if a bit heavier than before.

"Hmm, we need to do something about those things..." Lily murmured, standing on her tiptoes to reach up to the top of her brother's head, and suddenly everything was just wonderful. James felt his eyes fall half-closed, rolling up in his skull, tongue lolling out of his mouth with no input from himself. He collapsed onto his haunches, his voluminous butt pressing into his legs, hands on the floor to keep his torso upright. The dog morph's tail twitched madly inside his yoga pants, unable to wag with the constricting fabric around it.

"Aww, do you like that?" Lily cooed with a huge grin, continuing to scratch her brother's ears and head. "You like that, Jay-Jay?"

James only answer was uncontrollable panting, his left leg now twitching as well. The sensations were entirely non-sexual, but still pure bliss.

"Oooh, who's a good doggy, huh? Whooo's a good girl? Whooo's a goood girl?" The blonde obviously had a lot of fun, her voice overflowing with joy.

He was, of course! Only good girls got scritches! James leaned into Lily's hand, eyes now fully closed. Even through the tight fabric of his yoga pants, James' tail now thwapped into the floorboards.

"Such a good girl, suuuch a gooood giiirl," Lily cooed, her brother now drooling onto his arms from the tongue hanging out of his mouth, a dopey smile on his face.

Lily continued to cooing and scratching, James' mind entirely blanked out from happiness. It couldn't have been more than a few minutes until Lily stopped, but James lost all sense of time throughout it. When his sister pulled her hand back, James pulled his tongue back inside his mouth and pouted up at the blonde. Why did she stop? Wasn't he a good girl-- no, wait. He was a guy, wasn't he? But then again, his only male part was between his legs. And... good girls got scritches...

"Aww, don't look at me like thaaat," Lily smiled, tussling James' hair before she stepped to her wardrobe once more, taking out an oversized grey beret. "I just need something to eat, and fast. I promise, I'll give my favorite doggy scritches real soon. But first, put this one, okay?"

James took the hat, carefully flattening his ears forwards against his head before he but on the beret, receiving a thumbs up from his sister.

"Nice! It's a bold look, and you're rocking it! And nobody is going to notice anything."

The dog morph had to concur. Checking himself out in the full-length mirror on one wall, James had to admit he liked the way he looked. He'd never been particularly attracted to muscle-bound girls, but James had to admit being one himself wasn't so bad. Looking like his mother sucked, of course, so James avoided looking at his face as much as possible. He had a lot of other things to look at after all. Posing a little, James admired how his muscles bulged under his skin respectively his yoga pants. Not that there was much difference between either - the pants might as well have been painted on. The wide shirt and the grey beret completed the look, making sure that no one would look twice, even with the bulge of his tail running down his inner thigh.

"Glad to see you're finding a few silver linings," Lily smirked as she tugged her own tail away, following her brother's example of putting it against her thigh. Of course, she had to trade her beloved hotpants in for a pair of much longer shorts to do that.

"But there's one more thing we need to take care of..."
