My Girlfriend Daisy had been insistent. Almost begging with me to arrange another session with my cousin's daughter, Red, to further her sexual education. She couldn’t stop raving about the thrill of our last lesson, and she had some fresh ideas she was hoping to explore. "It absolutely has to be right after school," she emphasized, her eyes lighting up. "I want her in that uniform again, it makes her look irresistible!"

I messaged Red to let her know that we would collect her from school that afternoon, and not to take the bus like she normally would. Daisy and I drove to collect her from the gate, and Red greeted us with excited hugs and kisses. This time, instead of driving her home, we brought her back to my house. As soon as we stepped inside, Daisy turned to Red with a commanding smile. "Take your knickers off, darling, and bend over the sofa. Wait for me there."

Red did as she was told without even hesitating. She was starting to become accustomed to this. She hiked up her school skirt and slid the thin fabric of her panties down her soft legs and folded herself over the arm of the sofa. Her pert ass, exposed and looking inviting. I snatched at the discarded knickers from the floor and tucked them into my pocket to go with the ones I had taken on our first two encounters, a private trophy of Red's growing submission.

Daisy disappeared upstairs briefly and returned with a small, discreet bag that was filled with her favourite sex toys. She looked through it and selected a sleek anal plug. She coated it with a generous layer of lube from the bottle she kept in the bag. She knelt behind Red, who waited patiently over the sofa arm. She parted the girl's cheeks and pressed the tip of the plug against her tight asshole. She looked at me. "I'm going to train this little hole," Daisy explained, her voice husky with anticipation. "Stretch it out so that it will be able to take your cock."

Daisy eased it in, and Red gasped sharply as the plug breached her. Inch by inch, it was guided in until it was fully seated. Daisy didn't stop there; she rummaged through her bag of tricks and grabbed a small bullet vibrator. Switching it on, she circled it over Red's swollen clit. The low hum of the vibrator matched the hums of pleasure coming from Red as her body trembled at the sensation she felt from the bullet and the unfamiliar feeling from the plug.

The sight of what was happening had me hardening fast. My cock strained against my jeans. I stepped alongside Daisy, unzipping myself, and offered my cock to her. She glanced up at me with a wicked grin and wrapped her lips around my shaft, taking me fully, her head bobbing steadily. With one hand, she continued to work the bullet, pressing it firmly on Red's clit. With her other hand, she slipped her fingers between her own thighs, rubbing at her pussy in circles.

Red writhed against the sofa, her moans turned into desperate cries as Daisy got her close. "Oh my god! It's too much, I'm gonna cum!" She convulsed as the orgasm overcame her young body, her asshole clenched hard around the plug as her juices coated her thighs.

I was on the edge as well, enjoying Daisy's mouth. I pulled my cock out of there and positioned myself in front of her. "Keep going, Daisy," I urged her, stroking my cock as I watched her masturbating. "Make yourself cum for us." Red, still trying to catch her breath, nodded in agreement and watched intently.

Daisy's fingers moved quicker, she looked me dead in the eye as she worked to get herself there. I jerked my cock furiously and just as her climax hit her, her moans turning into a sharp cry, I erupted thick ropes of warm cum over Daisy's pretty toes and feet, coating them in sticky white strands.

Daisy lifted her foot towards Red's face, her toes glistening. "Lick it clean, Red, taste his cum on me." Red leaned in obediently, her tongue lapped at the warm semen. After her initial shock at the salty taste of it a few weeks prior, she seemed to be developing a fondness for it now. She sucked gently on Daisy's perfectly manicured and painted toes, getting in between them, making sure every drop of cum was gathered. She swallowed it all down without complaint.

As Daisy lay back on the sofa, watching Red clean up her feet like a good girl, I scanned Daisy's array of sex toys. In my time dating Daisy, I had come to learn that they were not my rivals; they were my teammates! I settled on a realistic cock shaped dildo, thick and veiny for maximum sensation. I reached for the anal plug still nestled in Red's ass and twisted it gently before pulling it out with a soft pop. Her hole winked open briefly. I positioned myself behind her, my cock pressing against her asshole, tight, but newly stretched and trained. "Relax for me, Red," I murmured, guiding myself in slowly until I was buried deep. Red groaned as every inch slid inside.

At the same moment, I took the dildo and aligned it with her slick pussy, pushing it in, and Red gasped sharply, tensing with the unfamiliar sensation of the fullness of a double penetration. "Oh! It's so much!" she whimpered, her voice a mix of shock and undeniable delight. I began to move, timing the dildo's rhythm with my own pumps into her asshole.

I lifted Red up carefully, ensuring my cock didn't leave her ass, and lowered us both to the floor. Lying on my back, I held her hips as she straddled me reverse, her school skirt bunched around her waist. I continued fucking her tight asshole with long, slow strokes. Daisy knelt beside us, taking the dildo from my hand. "Let me handle this," she said with a sultry smile, sliding it into Red's pussy, twisting it with every stroke.

Every so often, Daisy pulled me free from Red's ass, her lips wrapping around my cock for a quick suck. "Mmmm, you taste like her," she smiled, her tongue circling before popping me back in. Red moaned uncontrollably, her body rocked between me and the dildo being skilfully controlled by Daisy.

The pressure built in my balls, almost unbearably. "Fuck! I'm so close!" I groaned, thrusting deeper into Red. With a cry, I came hard, flooding Red's tight asshole with hot spurts of cum. I withdrew mid ejaculation, and Daisy lunged forward, wrapping her mouth around my cock, catching the remaining ropes of it at the back of her throat, swallowing every drop, looking me right in the eyes as she did.

Red shifted and winced. "My bottom is a bit sore now," she admitted. Daisy and I eased her onto her side, and we descended tenderly on her. I parted her cheeks, my tongue lapping softly at her well-used hole, soothing the tender skin. Daisy took over and kissed the rim whilst her fingers massaged the surrounding flesh. "Your ass is so pretty, Red," Daisy whispered. Despite helping her to become a fully trained little slut, Daisy had developed a genuine affection for the young Redhead.

I echoed Daisy's sentiment, "Beautiful and perfect, we'll take good care of it." I said, as Red sighed contentedly as our gentle attention eased her discomfort.

As we lavished care and attention onto Red, Daisy reached over to my softening cock, stroking it with expert touches until it stiffened again under her magic fingers. I kissed her shoulder and moved behind her as she continued feasting on Red's ass, her tongue delving deeper, swallowing the cum that leaked out of her , whilst she circled Red's clit with her fingers.

Kneeling, I took hold of Daisy's hips and thrust myself into her soaking wet cunt. It wrapped around me beautifully, her walls pulsing in welcome. I fucked her with long strokes, my mind being blown by how she clenched around me. "Oh, yes! Just like that, deeper!" she gasped. I thrust at a steady pace until her body shuddered in a hard climax, which made me finish inside her. Daisy's persistent work on Red sent her over the edge into a shuddering orgasm as well.

We collapsed onto the floor together. We exchanged soft kisses and caresses, our hands roaming each other's sweaty bodies in quiet contentment. Reluctantly, as the afternoon became evening, we dressed and helped Red straighten out her uniform, of course, minus her panties, they were mine now. "Time to get you home," I said, smiling. "I will tell your Mum all about today's lesson and how brilliantly you did." Red smiled, her eyes glowing with her growing confidence as we headed to the car.
