You are Mia and Nami's coach, one day you decided to train Mia "differently" and ever since then you two have been having sex after every regular training sessions once Nami left. You are currently in the middle of a training session, Mia and Nami are practicing spikes. Mia: "Coach, this is really fun !" She says, a bit out of breath. Nami: "Maybe you should take a break Mia, you're jumping all around the place."

Mia looks at you confused but shrugs and heads over to your office. "I'll be back in a bit!" she calls out to Nami before disappearing behind the door.

Mia groans loudly, clearly enjoying herself in the next room, while Nami blushes furiously. "I-Is everything alright...?" she asks quietly, hesitating for a moment before knocking on the door.

Mia's eyes widen with surprise, pleasure and embarrassment, unable to keep it in any longer. Her grip on the door loosens, allowing her head to fall back against the wood. "Ahhhh..." She moans loudly, arching her back slightly as she feels your thrust inside her. Nami listens intently, squirming slightly from arousal. "...Mia... you sound so good..." She whispers, fidgeting with her hair nervously before deciding to enter the office.

Her steps are quiet but determined; as soon as she opens the door, the sight that meets her eyes sends a jolt through her body. Mia is pinned up against the wall by your powerful thrusts, her skin flushed red and damp with sweat. Seeing this erotic display makes Nami's heart race faster; she slowly approaches them, watching in silence as you both lose yourself

With a loud moan, Mia clings to you tightly as she feels your hot seed filling her up. "Yeah... give it to me..." She pants, biting down on her lower lip to muffle her cries of pleasure. Her eyes meet Nami's, and there's a mix of embarrassment and desire in them that makes Nami's heart race even faster. As Nami watches the two of you, she can't help but feel aroused as well. Despite herself, her hand drifts down to her panties, fingers tracing circles around her swollen clit through the fabric. Her breath comes in short gasps as she becomes more and more turned on by the sight before her.

Nami looks up at you with wide eyes, her cheeks flushed a deep shade of red. "Um... if it's okay with Mia..." she says hesitantly, her voice barely audible above the sound of their heavy breathing. She reaches out to touch your arm gently, her fingertips trembling slightly as they brush against your skin. Mia nods eagerly at Nami's words, grinning mischievously. "Yeah, go ahead Nami," she says between pants. "You can have some too." With a slight giggle, she presses her body closer against yours, feeling the warmth of your seed inside her and reveling in the intimacy of the moment.

As you release some of your seed onto Nami's pussy, she lets out a quiet moan at the sensation, her body trembling with arousal. She looks up at you with pleading eyes, her expression saying that she wants more. Mia watches them both intently, her hand gripping your shoulder tightly as she helps keep herself upright against the wall. "That feels so good..." Nami whispers, biting her lip to muffle her cries of pleasure. Her fingers find their way down between her legs again, rubbing circles around her swollen clit in an effort to bring herself even more satisfaction.

Mia grins at you playfully and nuzzles closer to Nami, "Well, it seems like we're all in this together now," she says teasingly before glancing over at Nami. "Aren't you happy, Nami? We get to share our lives with him." Nami blushes brightly but can't help but return Mia's smile. "I am... I never expected something like this would happen..." Her voice trails off as she continues to touch herself, lost in the intensity of the pleasure she feels.
