[IENFH-014]

Playing a prank on my sleeping schoolgirl sister, she suddenly woke up and begged for unprotected sex—I couldn’t escape as she locked my balls in a crab clamp and forced me to cum inside her! Amu Ohara

Stumbling and barely able to move, the younger sister climbs the stairs after pulling consecutive all-nighters studying for exams. Her body feels heavy and weak. She collapses onto the sofa and starts dozing off. At some point, she briefly wakes up, muttering, "No... I can't," trying to get up, but falls back asleep. Just then, her older brother walks by. "Huh? What are you doing, sleeping here? Hey, you'll catch a cold!" He calls out, but she doesn't respond. "Hey! You okay?" he asks, concerned. She opens her eyes, dazed, whispering, "Ah... Onii-chan..." and suddenly hugs him tightly. The brother is pushed down, instantly aroused by her helpless state. He starts unbuttoning her blouse and peeks under her skirt, checking if she's really asleep. Suddenly, the sister wakes up and passionately kisses him, moaning, "Onii-chaaan." Surprised, he yells, "Hey! What are you doing?!" But she ignores him, clinging close and asking, "Onii-chan, what were you trying to do to your little sister?" He stammers, "I-I wasn't... I mean, I wasn't doing anything..." She smiles and says, "It's okay. I'll let it slide—just for today. I haven't had time to masturbate these past few days from all the studying." Tempted, he protests, "You idiot! What are you saying?!" She hushes him, "Shhh! You'll wake Mom and Dad!" He's shocked. "What?!" She reaches into his pants, touching his crotch, and giggles, "Just as I thought—it's Onii-chan!" He asks, "What's that supposed to mean?" But she's already stroking his hard cock, whispering, "Do you want me, Onii-chan?" He tries to resist, "Wait a second—" but his body betrays him. She starts giving him a blowjob, then switches to a deep kiss, and they immediately dive into a 69 position, greedily pleasuring each other. Both are turned on, but they suppress their moans, afraid of waking their parents. After switching back to a deep kiss, she begs, "Onii-chan, put it in me~. I need you inside. Otherwise, I won't be satisfied." He hesitates, "Huh? We're siblings—we can't have sex. Let's just rub, okay?" But she insists, "No way! I want it inside!" and guides his cock into her pussy. He protests, "You idiot! It's bareback!" She replies, "It's fine~!" He's too turned on to stop and starts thrusting. Holding her close, he covers her mouth with his hand to muffle her sounds as they continue. They switch positions—missionary, cowgirl, reverse cowgirl, doggystyle, standing doggystyle, standing face-to-face, then back to missionary. In missionary, the aroused sister suddenly locks his balls in a crab clamp and keeps moving her hips. He gasps, "I'm about to cum." She tightens the clamp, and he yells, "What are you doing?! Ahh!" as he erupts inside her. She clings to him, nuzzling close, and whispers, "Hey, let's do it one more time—in your room~," before locking him in another deep kiss, ending the scene.

せめて黒髪に染めてほしかった 兄妹の設定で見ても、実際にはお父さんと娘の関係に見えてしまうのはちょっと違和感があった。白髪のお兄ちゃんという設定は、どこかに違和感があり、それが全体の雰囲気を少し崩してしまった気がする。少し期待はずれではあったけど、全体として楽しめた作品だ。
