After cake and party favours, the foals trotted home — all of them except Diamond Tiara, who sat with her forelegs crossed on the sofa, waiting for her dad to come by and pick her up. He was always late.

Rarity trotted up to her, levitating the cake, and offered her another slice. She shook her head. The party had been rubbish, the birthday girl refusing to even come out of her room, and Rarity refusing to start any of the party games until Sweetie Belle appeared. Rarity put a forehoof on the grumpy filly's shoulder. "Why don't you go up to Sweetie's room and see if you can talk some sense into her? You could give her your present — it might cheer her up."

Diamond shrugged. "Fine!" She barely knew Sweetie, but her father had insisted she come to this party because they'd be starting at the same school after the summer. She didn't see why she had to make friends — she already had a friend. Diamond picked up the wrapped gift and climbed the stairs.

Diamond looked around the unfamiliar house. She didn't know which room was Sweetie's, but only one door was closed, and all the other rooms clearly unoccupied, so it didn't take a genius to work it out. She tapped the closed door with her hoof.

"Go away, Rarity!" came a squeak from inside.

Diamond pushed the door and it swung open. "I'm not Rarity," she announced. Sweetie turned her head towards Diamond. She had lipstick plastered all over her muzzle, was wearing a cheap imitation pearl necklace, and a dress several sizes too big, exposing most of her chest. If it weren't for the tears in her emerald green eyes, Diamond would have suspected that the little unicorn was playing dress-up.

"Go away, Diamond!" Sweetie squeaked, turning away.

"What's wrong, Sweetie?" Diamond asked in concern, trotting over to her.

"You're as bad as the rest of them. It's always Rarity this and Rarity that. Everypony always loves Rarity. Nopony pays any attention to Sweetie Belle."

"What? It's not like that." Diamond sat on the edge of Sweetie's bed, and looped a foreleg around her shoulder. "At least ponies turned up for your party."

Sweetie sniffed. "You had a party?"

Diamond frowned. "Yes, I turned five three weeks ago."

"I didn't know. I was in Manehattan with mummy then."

Diamond exhaled, blowing the tip of her mane out of her face. "So was Silver Spoon."

"Silver who? Never mind. Well, I'm sorry. Happy birthday for then." Sweetie took the loose strand of Diamond's mane and tucked the soft lock behind her ear to keep it out of her eyes.

A tear formed in Diamond's eye, and she threw her forelegs around Sweetie, crying. "It's OK." Sweetie comforted her, and stroked her long violet and white mane. Diamond held onto Sweetie tight, sobbing.

Diamond felt something warm, soft, and moist on her neck. She pulled back, sniffed, and wiped her eyes. "What are you doing?"

"Whenever I'm crying, mummy or daddy give me a kiss to make me feel better."

Diamond couldn't remember her mother, and her father was far from affectionate. "Does it work?" she asked. Sweetie nodded, and Diamond sniffed again, blinking the tears out of her eyes. "Do it again then." 

She watched as Sweetie's lipstick-covered face came towards her. She closed her eyes and felt the filly's lips make contact with her cheek. When Sweetie pulled away, the moisture that her mouth had left on Diamond's fur felt cool in the open air. Not wanting Sweetie's warm, comforting kiss to end, Diamond lunged forward and the two fillies' lips met.

Sweetie's eyes flew open in surprise. A kiss on the mouth had been unexpected, but it felt nice. Diamond's lips tasted faintly of the birthday cake Sweetie had missed out on, and Sweetie found herself starting to salivate. She instinctively licked her lips, and her tongue brushed against Diamond's mouth.

Diamond giggled. "That felt weird… your tongue."

Sweetie looked unsure of herself. "Sorry."

Diamond smiled. "No, it was nice. Let me show you." She leaned forward, slowly licking Sweetie's lips, her tongue gently tracing the top lip from left to right, then back along the bottom lip. "It's nice, isn't it?" Sweetie grinned; it had been nice.

The two fillies hugged again, and kissed each other gently. "Put your hoof here, on the side of my muzzle," Diamond whispered, "that's how daddy and his fillyfriend do it." Sweetie did as instructed, and Diamond's fur felt warm and soft beneath her hoof. Sweetie gently stroked Diamond's cheek, and Diamond pulled Sweetie towards her, hugging her tight, while her tongue continued to explore the birthday girl's lips.

After a few moments, Sweetie pulled back to take a breath. A string of saliva connecting their lips broke. She looked at Diamond and started giggling. Some of her lipstick had rubbed off onto Diamond's muzzle.

"What? What's so funny?" Diamond asked.

Sweetie suppressed her laugh. "N-nothing."

Diamond giggled. "No, really… what?" She pushed Sweetie gently on the chest.

Sweetie pushed her back mischievously. "Nothing!"

Diamond pushed Sweetie again, and the filly fell backwards onto her bed. Earth ponies are very strong and sometimes Diamond would forget her own strength. Diamond leaned over Sweetie to check she was okay, but when she saw the playful grin on the filly's face, it was clear that she was fine.

The enormous dress that Sweetie was wearing gaped down, exposing her chest and most of her belly. "Tickle fight!" Diamond squealed, her hoof heading straight for Sweetie's bare tummy.

Sweetie laughed, squirming and trying to push Diamond's hoof away. "No! Stop!" she squeaked, but the enormous grin on her face let Diamond know she didn't mean it. Diamond kept tickling Sweetie's belly relentlessly while Sweetie kicked her back legs, the long trail of her dress beginning to ride up, exposing her bare legs.

Sweetie's fur felt soft beneath Diamond's forehoof, and she couldn't resist kissing the filly again. Diamond stopped tickling and leaned over to press her lips to Sweetie's mouth, silencing her squeals at once. Sweetie raised her head up into the kiss, and looped a foreleg around the back of Diamond's neck, drawing her in.

Diamond moved her hoof in small circles on Sweetie's belly, ruffling the ivory fur. Sweetie shuddered. Diamond broke off the kiss and quickly drew back her hoof. "Sorry, did that tickle?"

"No," Sweetie whispered, a blush coming to her cheeks. "It was nice. Keep doing it… please?"

Diamond couldn't resist her pleading emerald green eyes, and responded by moistening her lips and pressing them against Sweetie's again, her forehoof returning to rubbing Sweetie's belly, in little circlular motions, each loop moving lower and lower, until she was brushing Sweetie's little nipples.

"Mmm…" Sweetie sighed happily, feeling warm and slightly tingly inside.

Soon Diamond's hoof reached the limit of what Sweetie's dress would allow. Diamond broke away from the kiss to ask, "do you want to take it off?"

Sweetie nodded. Diamond's belly rubs had been feeling better and better as she'd moved her hoof lower, and Sweetie didn't want that to end. She stood on the bed and used her hooves to strip the dress off. Rarity kept telling her to practice using magic, but she such a little filly, and was no good at that yet. She lay back down on top of the crumpled garment.

Diamond leant over Sweetie again and their lips connected. Her forehoof resumed its work, rubbing her belly, and cautiously moving lower and lower with each stroke until it strayed between Sweetie's legs. Sweetie gasped. "No! Not there!"

Diamond stopped and looked at Sweetie with confusion and concern — the last thing she wanted to do was upset the birthday girl. "It will make you feel really good. I do it sometimes. It feels nice."

Sweetie frowned. "Mummy told me never to touch myself there."

Diamond rested her hoof on Sweetie's flank and thought for a moment. "You won't touch yourself. I'll touch you. She didn't say I couldn't touch you, did she?" Driven by desire, Sweetie hastily rationalized that Diamond must be correct. She reached out and grabbed Diamond's foreleg guiding her down.

That was all the encouragement that Diamond needed. Her hoof sought out the soft, warm flesh between Sweetie's legs. Sweetie sucked in her breath when she felt Diamond's hooftip graze against her most private area.

Diamond traced her hoof slowly up and down the length of Sweetie's slit. It felt warm, and not wet, but moist. Sweetie shuffled slightly, spreading her legs a little — not much, but enough to give Diamond better access, and let her know that her attention was appreciated. Diamond leaned in to kiss Sweetie tenderly on the lips, and Sweetie closed her eyes and eagerly returned the kiss.

As the tip of her hoof slid carefully between Sweetie's lower lips, Diamond felt Sweetie quiver beneath her touch. Sweetie tilted her hips forward, pushing up against Diamond's hoof. While she built up speed with her hoof, Diamond broke away from Sweetie's mouth to plant tiny kisses on her neck, muzzle, and bright pink cheeks.

Sweetie's breaths became harder and irregular. Her eyelids fluttered open and her gaze met Diamond's. "Y-you were right, D-Diamond. It does f-feel nice." Diamond nodded and smiled, keeping up her steady rubbing, and feeling Sweetie's pussy grow warmer and wetter. Sweetie rocked her hips back and forth against Diamond's hoof and grasped at the bed sheets with her forehooves, a quiet whinny escaping her lips.

Diamond could tell that Sweetie was getting close to the good bit, and tried to locate the tiny nubbin that she knew would drive the filly wild. Finding the hard little button, she gently flicked at it with her hooftip, causing Sweetie's back legs to tremble, and a brief moan to escape her lips before Diamond silenced her with another kiss.

It was only a few seconds longer before a Sweetie let out a muffled squeal into Diamond's mouth. Her back arched and she clamped her hind legs together, trapping Diamond's hoof between them. Diamond felt something warm and wet oozing onto her hoof and kissed Sweetie back, using her other hoof to stroke Sweetie's mane to comfort and reassure her.

Sweetie lay on the bed, recovering her breath. "That was amazing, Diamond," she panted. "Do you… umm… do you want me to—"

"Diamond!" Rarity's voice drifted up the stairs. "Your father is here. Would you come down; he's in a hurry."

Diamond gave Sweetie a hug. "I'm glad you're happy now. I'll see you at school in a few weeks. I'm sure we'll be the best of friends." She trotted towards the door and down the stairs.

Sweetie sat up in her bed and unwrapped the gift that Diamond had brought her, a framed painting of an apple tree. She'd have to find a way to thank her next time they met.
