No need to ask

“I’m only doing this to get you off quicker” Lucy announced, trying to give herself an excuse for her own actions.

“What do you mean when…” you started to ask, only to have Lucy silence you as she moved her lips closer.

She stared up at you and seemed to thrive on the attention that you were giving her now that she had managed to silence you with just one small movement, her lips now pressed against your shaft.

Her tongue extended and while you thought she would tease you with small licks or kisses, she still seemed compelled by her active effect to help you out with your ‘problem’. Her passive effect was also the likely cause for her now being open to giving you head so you looked down at her while she quickly moved to the tip of your cock.

It seemed that your taste was to her liking as she closed her eyes once her tongue licked the tip before exploring the rest of your inches. She finally reopened her eyes to see you still staring back at her and she opened her mouth to accept you inside. She pushed herself down, all the while keeping eye contact in an effort to please you.

She let her lips slide over your length before starting to move her head back and forth, the touch of her tongue adding to the pleasure. You could tell she wasn’t holding anything back to get you off and wanted to try using her mouth to get you off as quick as possible.

Without even trying she managed to hone in on your more sensitive spots and then the fact that you could see one of her hands shoot down towards her crotch and inside her panties, didn’t help you hold back when you were trying to keep your imagination at bay. Your sister pressed on and you knew she was going to make you cum quicker than you expected.

Her technique of just hitting you with everything all at once was getting you close. The feel of her tongue, her lips sliding over your tip, the warmth of her mouth as she sucked. Everything she did was for the sole purpose of getting your cum inside her, whether that was for your enjoyment or her own was still up for debate.

“Fuck I’m getting close” you had to admit, Lucy hungrily keeping your dick in her mouth.

Her eyes widened when you were **** to hold her for support but that was the only other warning you could give her before you started to cum.

You stopped holding back as the pleasure ran through you, Lucy not pulling back as you shot off into her mouth. You felt her swallow around your cock as your load splattered across her tongue, coating the inside of her mouth and getting moans of approval in return.

She continued to urge more and more out of you while she had the chance, her own kink now in control of her actions to both make this as pleasurable as possible for you while also wanting to taste as much of your climax as she could.

Your orgasm lasted longer than you expected with her continued encouragement but even you couldn’t carry on forever, reaching a point where you became too sensitive to let her carry on, the last of your orgasm now deposited in your sister before you were **** to pull back.

It took more effort than you expected to pull out of her mouth however, trying to take a step back only for Lucy to move her head forward to follow you. You were softening in her mouth and she continued to still suckle, leaving you **** but to steady her head in your hands to push her away.

With you now away from her, you had a chance to take a breath and not move out of reflex, the sensitivity rapidly declining and allowing you to take a look more objectively at your older sister.

With you now out of her reach, she flopped back and rested where she was sat, no traces of your cum anywhere around her lips as she had already licked it all off. Her hand was still resting inside her panties but her fingers were no longer moving, looking like a puppet that had had its strings cut now that she no longer had a target to attack.

The white panties were soaked as far as you could tell and while your focus had been on your own orgasm, knowing you had indirectly made her reach her own climax made you feel better about treating her like a cum dump.

Lucy still looked a little out of sorts while you were readjusting but you could soon see a look of clarity once she realised she had given you a blowjob for the first time. Lucky for her, the active effect that had influenced her was now over when you had cum, giving her the excuse she needed to work her way out of this situation.

“Just remember I did that to get you out of trouble…Don’t go getting any wrong ideas” she announced, pulling her hand out of her underwear when she realised what she was showing you.

She raised her hand and you both clearly saw how wet her fingers were, causing Lucy to quickly stand up and wipe her cum with a nearby piece of tissue.

“You can go now” Lucy urged, a hint of embarrassment coming through in her voice after outing herself.

“Well I kind of need to use the bathroom. You know…school and everything” you replied, deciding to actually get ready for the day while you were here.

“Just go and use the one in Mom’s room… You're the one who pulled me in here in the first place so the least you can do is let me use the bathroom in peace” Lucy shot back.

“Fine fine. But I’m gonna need my underwear back if I’m going outside… unless you wanna do a swap. Mine for yours?” You suggested, reaching for the pile of clothes Lucy had discarded to grab what your boxers

“Nope. Just take them” Lucy groaned, turning away from you as if she didn’t care and not taking your deal.

You didn’t particularly care about putting your boxers back on and only asked on the off chance you could get her naked. With that option now out of the window, you finally decided to leave with your underwear on hand, not even bothering to put them on as you opened the door.

“Thanks for the help” you added, Lucy still not looking at you as you slowly closed the door behind you.

You made it seem like you had left and waited with just a small gap in the door, waiting to see what Lucy would do now that you were gone.
