Stepbrother!Denki Who immediately has hearts in his eyes when his gaze falls upon you. You're picture perfect! An angel sent from heaven, fulfilling his every fantasy of what a girl needs to have 'equipped' to make sparks fly as his quirk goes into overdrive and his cock starts to painfully press against the confines that are his pants. Or maybe this is divine punishment for him being a perv all his life, because his father introduces you as his new sister and not the future wife he was hoping for.
Stepbrother!Denki Who can't help his instincts around you when he engulfs you into the tightest hugs you'll ever received. All just to feel you up and have your curves mold against him—you can hear the sigh of relief (or was it a moan?) right against your ear as he buries his nose into your hair and takes a big wiff of your sweet scent.
Stepbrother!Denki Who doesn't feel the slightest need to back off with his displays of affection around you, your parents or anyone else really. You're his sister and he wants to bond and have a good relationship, that's all there is to it. He's got his hands on you at all times: guiding you by the small of your back, tits squished against him with every hug, legs thrown over his lap on the sofa or a subtle squeeze of your ass when he walks past you.
Stepbrother!Denki Who can't stop talking about you whenever you're not around. Mineta always listens intensely while the rest of his class just wants him to shut up and Bakugo even sent him flying out the window with a grand explosion one time when he mentioned your favorite color must be blue because all your underwear is different shades of blue.
Stepbrother!Denki Who picks you up like you weigh nothing and sits you down in his lap at every opportunity or hand feeds you fruits that he peeled specifically for you. He always wears that stupid grin around you as well—the one that doesn't feel like much, but is too boyish, too mischievous and too dazed to be innocent.
Stepbrother!Denki Who tells you scary stories and hopes you won't be able to sleep alone and beg him to keep you company. In the end, he is the one who holds onto you tight during the whole night and can't get a wink of sleep in the dark. He's curled up around you, shakes like a leaf and presses your face into his chest while murmuring soothing sentences that serve more to calm his own nerves than yours.
Stepbrother!Denki Who finally gets you to agree to take a long, relaxing bubble bath with him. Hero duties have worn him out, your presence always helps him relax and underneath the bubbles he won't be seeing much of you anyways...it's just like a mixed gender hot spring and people go there all the time, right? You understand, don't you?
Stepbrother!Denki Who loves the shy way you undress in front of him and how your cheeks dust pink even before you enter the hot water. He really tries to keep his cock from stirring to life underneath the water but every attempt is futile when you look so cute sitting on the opposite side and your feet brush against his thighs.
Stepbrother!Denki Who helps you ease into the water and relax, telling you to turn around and lean against his chest. Big brother Denki will take care of everything you need today. He starts slow by running his hands up and down your arms before they make their way over to your middle, pulling you closer so you can feel his cock press into your back.
Stepbrother!Denki Who truthfully had innocent intentions (or at least that's what he tells himself) when he massages your tits and kneads the inside of your thighs like raw dough. It's just to take care of you, of both of you, and because he loves you so much. Always has, always will.
Stepbrother!Denki Who cums right then and there. With the added stimulation of your squirming and the way your slippery skin feels, he really couldn't hold it back—the little twitches of his body behind yours make the water surface ripple slightly and a pathetic whimper escapes him as his head falls forward against your shoulder.
Stepbrother!Denki Who holds onto your hips when you try to stand up in panic right afterwards and almost cums a second time with your beautiful ass right in front of his eyes. He can't help himself when he buries his face between your cheeks, nose grinding against your rim and tongue already taking the first taste of you mixed with the artificial flavor of the bath additives.
Stepbrother!Denki Who didn't wanted it to end this way, but has you bent over and kneeling on all fours in the shallow water of the tub while he stuffs his face full of you, fingers sinking into the fat of your hips to keep you close and simultaneously pull you impossibly closer. Your scent drives him insane as his tongue licks and pokes at everything within reach without rhythm or clue as he's driven by pure instinct. Your clit, your pink clenching hole and cute puckered rim—nothing is safe.
Stepbrother!Denki Who apologizes profusely after he carried you into his room, dressed you comfy and cuddled up with you under his messy sheets. But his teary eyes widen in surprise when all you do is press closer and press a small kiss to his nose with a little giggle, telling him that you hope he feels better now and that you'd like to take care of him as well after everything he's done for you. You're now being brother and sister after all...
