(A/N: This is a lemon. I wrote this on a document as an imagine, so just bear with me guys! BxG, Sebastian's POV. Crush is you, and for the sake of male, female and diverse genders I am using they/them pronouns (please excuse any others))

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Imagine your crush slowly pushing you onto a couch and kissing you softly. They deepen that kiss whilst pulling away just a tad and catching your bottom lip between their teeth. They lightly nibble then suck on your lip before shoving their tongue into your mouth and feeling around just a little. Pulling away teasingly. They slowly run their hands up the back of your shirt and drag their nails down your back, occasionally scratching deeper, leaving red marks along your back from top to bottom. They move back and sit on the floor, tugging at the front of your pants and boxers, giving you a knowing smirk with a dangerous and sinful look in their eye. You knew this would happen. And you know what happens next.

With that knowing look, they move closer, kissing your thighs whilst slowly and gently grasping your dick and licking the underside of the shaft from base to tip. They lightly suck on the head before lowering their head, taking more of your length into their mouth. They suck softly while bobbing their head slowly. They grab your hands and moan just a little as they pull up to take a small breath, they give your hands a squeeze before standing and slowly removing their clothing items, one by one. They keep on their panties to be a tease and they sit beside you, letting out a pleasant hum of satisfaction, a hum that sends shivers down your spine. "Are you ready?~" They ask in a soft hushed tone, their hands moving over your back and down, along your dick slowly. "I know I am~" They let out a small laugh as you smile and sit back, awaiting their next movements.

They looked over you slowly before moving onto your lap, so they are facing you. They placed their hands on your shoulders, squeezing them slightly before gently grinding their hips against yours, they moved their hands down to your chest and set their head on one of your shoulders, they moaned softly as you closed your eyes and tilted your head back, giving them space to bite and suck on your neck. They moved the underside of their panties to one side soon enough and they reached for your dick, grasping it lightly they rubbed the head against their entrance, their hole rather wet from the previous play of teasing you. As they slowly lowered themselves onto your dick they moaned out softly into your ear "Ooohh~ Y/N~" They would whisper as they took in your entire length, slowly raising and lowering their hips, causing your dick to flinch and you yourself to lightly buck your hips into them, driving your dick deeper into their tight, wet hole.

They smiled and moaned out as you set them onto their side on the couch, they smiled and let out a happy breath as you started to thrust into them, they moaned out happily, begging for you to keep going, pleading for you to slam into them, take them and mark them as your own. They continued to work their hips back on yours before they quickly moved away, grinning at you teasingly and as you let out a soft annoyed groan they slowly got back on the couch, laying on their back for you, legs spread, offering their hole to you and you alone. Did you take that oh so generous offer? Yes, you did, you grabbed their legs and set them over your shoulders, and as you drove your dick back into them they let out a scream of pleasure as you pushed much further into them than ever before.

You slammed a hand over their mouth to try and keep them quiet, but you knew that their moans, squeals and screams would only turn you on further, you smiled at them and they looked up at you innocently as you thrust hard and deep into them, you slammed into them, pressing against their cervix causing them to let out another scream into your hand, you shuddered at the muffled sound as they bucked their hips a few times, closing their eyes tight and shuddering as they were soon panting heavily. Their hole was tighter than before and you pulled away with a gentle groan, your dick was slick with their cum. You flipped them onto their front and held their hips, going back into them you moved your hips slowly, back and forth causing the one under you to moan softly as they caught their breath over time. You looked at them knowingly before leaning over them, driving your dick deep into them again, making them let go of a high pitched moan which only made you chuckle.

You slammed into them a few times, biting their shoulder harshly, you closed your eyes and moved your hands under their front, holding their breasts in your hands. You made them arch and stand slightly and while you squeezed and played with their nipples you fucked them faster and harder, causing them to let out another loud moan, they cried out your name and you felt them tighten up around your dick again, you groaned and bucked your hips a couple of times before pulling out and letting out a huff, you released them from your hold and watched as they collapsed onto the couch yet again. You watched their body rise and fall quickly with their quick deep pants and soon enough the two of you were sharing eye contact. You knew it, from the look in their eyes, that they wanted more, you also know they wouldn't last much longer which only caused you more enjoyment. You pulled out the hair tie that was keeping their hair done up in a neat bun. You grabbed their hair and pulled back, forcing them to stand up.

You got them to lean a bit more forward so they were holding onto the couch. Then you did nothing besides slide back into them. And you waited, you waited till they looked back at you and whimpered, you leaned forward, giving them a rough kiss, making them groan, said groan turned into a loud moan as you rammed into them a few times. You pulled back from the kiss and pulled on their hair, going back to biting their shoulders and marking their back, soon enough marking their neck in multiple noticeable places. They moaned out louder, begging for you to go faster, you granted said wish and muttered a few harsh words into their ear which only turned them on further "Consider this your punishment pup~" This made them snap their hips back onto yours and they moaned out, another orgasm racked their body and you let go of their hair as they collapsed for the last time.

You weren't done, however. You grabbed their hips and pulled them back onto your length, you pounded and slammed and shoved your dick as far as you could into them, their screams and cries of pleasure were music to your ears, their dirty words teased your mind, this only encouraged you further. You scratched down their back as they arched and moaned, you continued your fast deep pace before letting out a few soft grunts, you slowed your pace, teasing yourself and the one underneath you and that's when you felt it, you quickly pulled out and grunted and as you jerked off for barely a few seconds before releasing your load onto their back. You panted and slowly sorted yourself as the other shivered and smiled. You helped the other clean up slowly and then held them close, you gave them a small kiss, praising them on how well they did, and soon enough the two of you were asleep on the couch, exhausted from your wonderful, thrilling experience.
