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."

Nami watches Mia intently as she makes several attempts to perform the spike jumps, cheering her on with words of encouragement. She wipes away a bead of sweat that trickles down her temple and adjusts her sports bra, trying not to get too distracted by how breathy Mia sounds from exertion.

When it's finally Mia's turn again, Nami feels a jolt in her stomach as she anticipates the spike attempt. She bites down on her lip anxiously and unconsciously crosses her arms over her chest, wishing she could be doing more to help out. Despite this, she remains focused on watching Mia's every move with intense concentration, silently cheering her on.

Nami's cheeks flush as she feels her body heat up even more under the coach's gaze. She briefly glances down, taking a moment to compose herself before nodding firmly and squaring off against the net once again. With renewed determination, she springs forward with increased speed and agility, her muscles tensing as she gathers momentum for another spike jump attempt. The anticipation of the movement causes her breasts to press against the fabric of her sports bra while her tight panties hug her curvaceous ass, accentuating every flex of her powerful legs.

As Nami finally releases the ball with all her might, there's a loud slap as it connects with the ball on the other side before skimming over the net toward Mia. The coach watches intently as she tries to return it, taking note of each movement and stride that Nami makes during this attempt

Nami's heart sinks as she hears the news that she lost the mock match. She knew she could do better and is disappointed in herself for not measuring up to Mia's abilities today. With a heavy sigh, she picks up her water bottle and takes a long swig, trying to quell some of the rising frustration within her.

"Yeah..." Nami mumbles softly, "I guess I just need more practice." She glances over at Mia briefly before looking back down at the floor, unable to hide her disappointment. "Sorry Coach, I'll do better next time."

Nami looks over at Mia once more, feeling a mix of admiration and jealousy towards her. "I know... I just wish I could be as good as you." She sighs again, then shakes her head resolutely. "Anyway, we should get to the showers now, right?" Her tone is slightly more upbeat, trying to change the subject and focus on something else besides their current lack of success in practice.

Mia nods in agreement, flashing a reassuring smile at Nami. "Yeah, I'm looking forward to it too," she says with a wink. "Who knows? Maybe after we'll have enough energy left for another round of... spike practice?" Her eyebrow arches playfully, teasing both herself and Nami about their secret post-training activities that they don't want anyone else to know about just yet.

Nami smiles bashfully at the idea of taking a shower with Mia and their coach. "I-It would be nice..." she murmurs, her cheeks turning slightly pink from the anticipation. She glances over at Mia, who gives her an encouraging nod before looking back at you expectantly.

Mia, on the other hand, seems eager for the shower already. "Alright then," she says with a grin, nudging Nami playfully in the side. "Let's get going, shall we?" She leads the way toward the locker room, making sure to give her tight behind a little wiggle as she walks.

Nami blushes and hurries to follow Mia's lead, not wanting to be left behind. As they enter the locker room, both girls quickly begin changing out of their sweaty clothes, revealing their tight, curvy figures in various stages of undress. Mia lingers a bit longer than usual, teasing Nami by taking her time with her bra and panties. The excitement of having another secret session with their coach after the shower is palpable between them.

As they near the shower room, Mia can't help but feel her anticipation building. She looks at Nami with a mischievous glint in her eye and leans in close, whispering seductively, "You know... we could always invite Coach to join us." She giggles softly, enjoying the idea of getting even more intimate with all three of them together.

Nami's face turns bright red at the suggestion but there's also a hint of excitement mixed in. She glances over at you shyly before whispering back, "Really? I mean... we could try it, if he wants to..." Her voice trails off as she imagines the two of them with their coach, moaning and writhing together in the shower.

Mia grins, looking like the cat that's gotten the cream. "Of course he wants to." She squeezes Nami's arm playfully and winks before leading her over to you both. "Coach," she says seductively, leaning in close enough for her breasts to graze against your arm, "do you think it would be alright if... we invited you to join us?" Her breath is hot on your neck as she whispers the words, her body language making it clear that she means exactly what she's saying.

Nami bites her lip anxiously, watching your reaction with bated breath. The air feels thick with anticipation and desire as all three of them stand there together, barely able to contain their arousal.

Mia steps even closer to you, her breath warm against your ear as she whispers, "To join us in the shower. We're all a little sweaty, after all..." Her fingers trail down your chest teasingly, making it clear that she means more than just washing up.

Nami swallows hard, her gaze fixed on your reaction. She bites her lip again and shifts nervously from foot to foot, unable to hide the excitement that's coursing through her body at the thought of being this intimate with both Mia and their coach.

Hearing your consent, Mia's eyes widen with excitement as she pulls you even closer. "Great!" She squeals playfully and then turns to Nami, her grin triumphant. "See? I told you he wanted it too!" With renewed confidence, Mia grabs your hand and practically drags you toward the shower room, giggling and bouncing along like a excited child.

Nami blushes brightly but can't help but feel relieved and thrilled by the developments. She trails behind them both, her heart racing with anticipation as they finally reach the shower area. The tension is palpable in the air as all three of them stand there together, barely able to contain their arousal any longer.

The sound of running water fills the room as Nami tentatively steps up to one of the shower stalls and turns on

Mia waits impatiently for the water to heat up as she watches you and Nami undress. She can't help but let out soft moans of desire, her body already craving your touch. Once the water is warm enough, she steps into the shower stall with Nami, pressing their bodies together from behind.

"Coach," Mia whispers in Nami's ear, "join us..." Her hand slips between them, pressing against Nami's wet and already swollen sex. "Please... let's make it a good time for everyone." Her other hand trails up your chest, stopping just short of teasing one of your nipples.
