Mira waited until Joan was in her room alone, rooting through the closet, before she approached the princess.
"Excuse me... Mistress?"
Tara looked at her. "Yes, dear?"
"Can, um... I ask you something? Please?" she asked, shifting nervously.
"Sure, go ahead," the princess said. Mira moved in close, whispering something in her ear. The princess smiled as Mira moved back, and laughed a little bit. Mira blushed a little bit, and the princess said, "Yes, I think that'd be a lovely idea.
"Joan!" she called out to the other room. "Come here, pet."
While she waited for Joan to come out, she fetched the key for Mira's chastity belt, and carefully unlocked it, gently placing it aside, then putting the key back. Joan stood there, only half-dressed-- which was half more than Mira-- and looking the princess, wondering what she wanted.
Tara smiled, and took Joan, stroking her on the cheek. "Mira would like to play with you for a bit," she said. "Isn't that so cute?" Joan seemed a little too embarassed to respond, and Mira just looked away.
"Er... if you want to, of course," Mira said quietly.
"Of course she does," Tara said, still holding Joan by her waist, pushing her in close to Mira. "Isn't that right, dear?"
Joan hesitated unsurely, but then nodded, realizing that she wasn't really being asked. "O-of course," she said, looking nervously at Mira's naked body.
"Well, both of you, on your knees," Tara said, took a step back, smiling at the two as they quickly knelt down; but then Mira just sat there, feeling almost as uncomfortable as Joan as she realized she wasn't actually sure of what to do at all.
The princess sighed a little. "Don't know what you want?" she asked, disappointment in her voice. Both the girls turned to face her, and Mira nodded. "Well... I suppose I could help. Start with a kiss, pet."
Mira nodded again, and she leaned in, waiting for Joan to turn her head, and placed a kiss gently on her lips. Then she murmured quietly, "Sorry...."
Joan wasn't sure what to say or think, but she knew it felt nice, and she knew how her mistress expected her to respond, so she satisfied both desires by kissing back with equal gentleness, then kissing again, feeling the warmth of her soft lips. Then she tilted her head a little and kissed more, poking at Mira's mouth with her tongue. Mira parted her lips slightly, only letting her in just a little.
"Don't stop," the princess ordered, walking away to her other room in the corner, "I'll be right back."
They kept at it, Mira quickly letting herself go, eagerly kissing back at Joan, wrapping her arms around Joan's neck. She closed her eyes, continuing at Joan's mouth deeply, surprised a little when she felt a hand on her shoulder. It was the princess.
"That's a good girl. Now hold still," she said, and Mira paused from the kiss, a little puzzled by the order. Then she felt the princess's hands slip underneath her wrists; confused, she opened her eyes to see what was happening. Tara had put a collar around Joan's neck, and now Mira's wrists were being tied tightly together, the princess tying the cord through a loop in the collar for good measure, so Mira couldn't remove them at all. Once she was done, she patted her on the head gently, smiling. "There you are.
"Now...," she whispered into Mira's ear, "Tell her she's beautiful."
Mira stared up into Joan's eyes, her lips still pressed against hers. Hesitantly, she said, "You are...," then added, "Really, you are... I-I'm not just saying that."
"Do you love her?" Tara whispered.
"Of course... I love you, Joan," Mira said softly. Then desperate to prove it, she continued, "I'm glad to have someone else around... someone like me, who understands."
Joan just blushed a little.
"Now prove it, show her," Tara continued. "Worship her."
Mira kissed her lips gently, murmuring, "I'm so glad you're here." Then she bowed her head, lowering it until her lips were brushed against Joan's lower lips; Joan shivered, and Mira was about to kiss them too before she stopped, and glanced up, making awkward eye contact. "I'm sorry...," she said softly. "May I?"
Tara grinned, pleased, and then whispered quietly in Joan's ear, "You can refuse if you'd like."
Joan murmured contemplatively, considering how she should respond. Mira breathed hotly on her, begging, "Please...." Joan shuddered, and nodded gently, wanting her to.
Mira quickly went to work, kissing and licking and rolling her tongue inside; Joan moaned out loudly, amazed at the ecstacy brought by Mira's gentle mouth, quickly bringing her to climax then easing her through it, hardly pausing for breath as Joan moaned out loudly. Only once she was sure Joan was finished did she raise her head, licking her wet lips and gulping, staring into Joan's eyes.
"Thank you...," Mira whispered. Joan smiled, leaning down and kissing Mira on the mouth. She stroked Mira's sides, letting her squirm as she gently ran her fingers along the sides of her breasts.
"She's all yours," Tara said quietly into Joan's ear, ruffling her hair a bit. "How will you reward her?"
"Mmm...," Joan said softly. "Kiss me," she whispered against Mira's lips, teasing her by gently running her fingers across her sex. Mira shudddered, unable to respond in any other way; closing her eyes while she kissed back, her arms forced tightly around Joan's neck, happily delving into her warm mouth.
