After school, the excitement of the sports festival still lingers. As the lively after-party echoes through the school building, the introverted protagonist is killing time alone in a corner of the classroom. For him, such bustling events are uncomfortable. Then, a pair of flashy, popular gals with perfectly styled hair and makeup, wearing their sports festival class T-shirts in a revealing, disheveled way, show up. They don't notice the protagonist and start filming selfie dance videos on their phones. Probably to post on social media.
Yui says, "Hey, you know that event at the sports festival where guys and girls were hugging each other? It was trending online, right~" Kanna responds, "Oh, that thing~ The one that looked like a train station bento." Yui laughs, "Station bento, lol." Then Yui continues, "After exercising, you feel like fucking, right? I used to be in the basketball club, and after practice, I'd always go straight to the sports equipment shed with my senpai and fuck, lol." Kanna agrees, "I know, lol. I also used to fuck on the rooftop after PE class pretty often. And just now, everyone on the school grounds was getting all lovey-dovey and kissing."
The protagonist thinks to himself, "I can hear everything you're saying..." and figures that modern gals seem to get horny after exercise (something irrelevant to him). Then, the two gals, still in high spirits from the sports festival, notice the protagonist and start interacting with him.
Yui is startled. "Eek! If you're here, at least make your presence known!" Kanna also says, "You scared me... I thought you were a ghost." Yui presses him, "Hey, you heard our conversation just now, right?!" Kanna adds, "So you heard me say 'station bento'! How embarrassing!" Yui asks, "What are you doing in the classroom? The after-party is lively, you know? Not joining?" Kanna continues, "And you? Don't you feel like fucking?" Yui shows interest, "Oh, I kind of want to hear that, lol. Like, does a quiet guy like you have any sex drive?"
Kanna says, "Ah, I see... Actually, you're not bad-looking when I look closely. Show me your forehead a bit." She approaches and lifts his hair, exposing his forehead. Kanna says, "Don't move, lol. See, this is definitely better." Yui also says, "True! Hey, you have a pretty nice face, don't you? You're a diamond in the rough, lol." Kanna continues, "What, you're unexpectedly athletic and have a good face... You'd be popular, lol. No, that's why don't look away... That's it... You're shy, aren't you? If you could make eye contact and talk properly, I think you'd be pretty good."
The protagonist finds himself being examined by the two, who see potential in him. Yui suddenly says, "Hey, wait... Seriously, it could work. Um, what do you think of me? Is it a yes?" Kanna laughs, "Whoa, Yui, you're amazing, lol." Yui explains, "No, it's because after exercise I'm all hot and bothered, lol. So, if it's a yes... even a little yes... can I tempt you a bit?" She wraps her arms around his neck, hugging him in a station-bento-like position, and as Yui gazes at him, the mood gradually heats up.
Kanna says, "Ah~, Yui's switch has been flipped." Yui whispers, "Just leave it all to me, okay... It's fine... I actually really like your type, for real!"
Teased and seduced by the two, they start kissing him on a whim and simultaneously attack his nipples and dick from all directions. Yui laughs, "It's hilarious that you're getting hard from us, lol." Kanna says, "Want us to make it even harder? lol." Yui says, "Everyone's at the after-party, so no one will find out if we fuck!"
With the lingering excitement of the sports festival, the mood escalates into a spontaneous threesome. The two gals' sweaty, tight bodies are just too amazing, and he forgets all about joining the after-party, creampieing them over and over. Why don't you experience this youthful harem sex for yourself?
