The summer heat blazed outside but Collin had bigger fish to fry at the moment: the Kaiju dead set on destroying the city, which could only be stopped by his mech team. The skinny deer boi tapped on the handheld game, a tongue hanging out with concentration as movement ranges were checked and he then stared down the end turn button.

The house's front door swung open and shut, followed by the clatter of the wooden sign against it (All in a Doe's Work) as somebody entered. At this time of day, it could only be his older sister and sure enough she strolled into the living room a moment later.

"Heyy dweeb," Chloe said cordially on her way toward the kitchen.

At that he looked up but any retort he had in mind was silenced in the time it took to see her pulling her hair out of a bun and letting the golden locks loose. She was clad in a snug leotard, leaving a busty hourglass figure covered only by thin nylon while wide, white speckled hips swished. A nicely rounded, white frosted butt looked bare viewed from the side. Huge pointy breasts stretched the top, with a thin strip reaching down her front and between her legs.

Noticing his slack jawed stare, she halted in the kitchen doorway. The rear view was mostly her natural fur and curves, with the only hint she was wearing anything being a small triangle under the base of her tail. The garment disappeared between shapely butt cheeks which, with the white of her inner thighs, almost traced out a heart shape that reflected in his eyes.

"Hm? What's your problem?" She was peeking at him over a shoulder.

"O-oh, just your outfit. You wear that all the way home from practice?"

A shrug, "Yeah. It's hot out, so I figured why not?"

Without further discussion she slipped into the kitchen, hooves tapping on the tiles followed by the fridge opening. Collin slid off the couch, as the idea of an afternoon snack suddenly sounded great. His sister never brought the groceries but she always had milk.

Chloe reached for something in the fridge when his face dawned from under the curve of her bust. He had stood hidden under the sizeable blind spot until she leaned down.

"Yes? Can I help you?"

"Um...I'm a little hungry,"

By that he meant deficient in vitamin D. She could tell what he was thinking standing there eye to nipple with her. Hers weren't hard, but they were still obvious under the incredibly thin fabric.

"We're all out of milk," She said, straightening and placing hands on her hips, "If you wanted some you should have asked dad,"

"But then he'd disappear," Collin insisted.

Despite the roll of her eyes, her mouth twitched into a grin momentarily.

"Stupid," she replied, but with a humored tone and an affectionate pat of his head.

With a deep sigh, she tugged at the fabric of her garment, pulling and letting it snap back against her breast which jiggled slightly. Collin meanwhile embraced one of her legs, chin on her hip as he looked up at her with the most pleading, big-eyed expression that he could muster.

"Okay, fine, whatever. I'm gonna have to strip this whole thing off I guess,"

Collin perked up excitedly, releasing her leg.

"Thanks so much!"

Before the thanks was even out of his mouth, Collin reached up behind her and there was a twanging sound. The garment fell slack just enough to slide off her nipples. Though he wasn't quite able to reach even while standing on the tips of his hooves, mouth working like a fish with anticipation. She planted a palm on his forehead pushing him back down.

"Sheesh, hold on a second! I'm gonna get comfortable first. You won't starve in like five seconds,"

A moment later, Chloe seated herself on the couch as Collin gripped the armrest with excitement while she slid the leotard down her leg. Bundled up, it looked like a mere washcloth as she set it aside. Fully naked now, she crossed her legs to preserve some scrap of modesty as she patted the cushion. Her brother didn't need any more of an invitation and zipped up to kneel by her side. His gaze darted from her face to her breasts, covered and supported now only by her hands and arms. 

She gently released her breasts from the hug, leaving them to be cradled only by gravity. The pair was heavy, sagging a bit with the pink nipples pointed slightly down and outward from the white fur striping the front of her body. Her chest was softer than any pillow- this he confirmed as he rested his cheek against the closest boob. With his nose now aimed toward her armpit, he could detect the faint floral scent of her deodorant just barely overpowering the sweat worked up during gym practice. As well as the herbal wake of her swishing hair as she swept it back over her shoulders.

Lowering his head, he savored the coming meal as his finger moved back and forth over the nipple. It was stiffening as he gave it an experimental lick, eliciting a soft sigh from her. She wrapped an arm around him and leaned her head back on the couch, wincing a bit from the intense tickling sensation as he latched on to her. His lips pinched the point of her breast, and soon her nipple was being stretched and released rapidly. Fresh doe milk rolled in a delicious ebb and flow over his tongue.

The stretch and release was like a pleasant massage, a rhythm of sensation that lulled her to lounge back with eyes half closed. Meanwhile he pressed his muzzle into her breast, leaning forward with a hand braced on her thigh. His fingers slid ever so slightly until he could feel the downy tuft peeking up from where her legs were still firmly crossed. Heat from delicate lips touched the tips of his fingers. The thought lingered, began to stir until he felt his shorts growing tighter. Not for long though. His hardening cock easily slipped down the loose leg of the shorts.

Chloe raised her head slightly, as if rousing from a nap.

"What's that? Am I sitting on a game controller or something?"

His lips parted from her breast with a wet smack and a couple drops of doe milk dripped.

"Uhh..nope. That's me. Sorry, couldn't help it!"

"You wish," She laughed, "That's too big to-"

Her hand found a thick and rock hard shaft, pulsing in her grip in the several seconds she took to process what she was holding. She sat up and looked down, eyes confirming what she was feeling. Collin's cock was so thick that it forced his legs apart. It had stretched the shorts halfway down his legs, pulling the waistband down so that a set of fat balls spilled out to either side.

That third leg of his was probably just as long as he was tall. Chloe shook her head, eyes moving up to his nervous grin and a hand behind his head.

"Sorry!"

"No, it's fine," She was quick to reassure, "I was just surprised. You're, uh, pretty big,"

"Oh? Cool!"

A smug grin came over his face as he rested his chin on her breast, "Bigger than your boyfriend?"

She gave a nod, "Ohhh, yeah. A <>lot<> bigger,"

The shaft flexed under her fingers, as a small burst of thick seed squirted across her lap.

"Uh, you're kinda leaking a lot too,"

She tried to find a better position for the both of them but the sizable cock wasn't easy to get out of the way. And being jostled around, rubbing and bumping against her curves wasn't helping the situation very much. She glanced around, picked up a throw pillow but then put it back. He was making a mess and it was going to be her or the couch. Neither option an ideal one. After some thought, she uncrossed her legs.

"Here. Just stick it in so you're not squirting all over the place,"

Spreading her legs revealed a set of plump lips pressing a perfect line between them. As he stepped in between her legs, she slid his shorts down and then took hold of his cock to help guide it in. He pressed forward with hunger of two kinds now. She was tight but he slid in with some effort on both their parts. She arched her head back, drawing a sharp breath as his knot bumped into her and then he was fully hilted. Then cradled his head as he returned to his meal, this time sucking from the other breast so as not to throw her off balance in gymnastics.

Chloe lay back, sinking into the couch as Collin sat lodged in her and extracting more of her nutritious milk. But now she was milking him- grinding against him and working against the massive member stretching her pussy.

He wasn't complaining, as she hugged him close and buried his face into her boob. Her chest rose and fell against his face, increasing in pace as he throbbed deep inside her. His groan was muffled as pressure built. 

"Nnh..god," She hissed through clenched teeth.

Full of doe milk, he deposited a load in return. His cock twitched and he released a hot stream against her womb, a single long burst that didn't seem to end. And when it finally did, he spasmed and spurted a couple more times before he was done. 

Suffice to say, dinner was on her from that time forward.
