"Okay, I'll go with you."

“Please, baby. It would mean so much to me if you went Christmas shopping with me. We hardly ever spend any quality time together…” your mother is practically begging you from her position on the floor. You tune her out, instead focusing on the way her huge tits jiggle and wobble as she gestures animatedly with her hands.

“Okay, I’ll go with you.”

“…I mean, I just feel so comfortable around you and I’d hate for you to be here all by yourself – wait…” she pauses and looks at you like you’ve grown a second head. “You’ll go?!”

You nod at her and smile. It’s honestly a kind of endearing to see her so openly excited, and about you spending time with her no less. What you would have given to have this happen at any point earlier in your life.

Your mother practically launches to her feet, breasts bouncing excitedly as she approaches you. She makes to give you a hug, but looks down at her cum-covered breasts and thinks better of it.

“Thank you, John. I know you don’t like going out very much, but you won’t regret deciding to come with me,” she licks her lips and pushes her breasts upward with her arms.

Your cock bobs as a wave of arousal hits you. Goddamn, even though you just came you feel like you could go for another round of titfucking.

“I’ll just go clean myself off and get changed and then I’ll meet you downstairs,” she says. At your critical look she rolls her eyes. “Mommy won’t wash off her breasts. I promise,” and with that she leaves opens the door and leaves your room.

It’s only a after you’ve started to head downstairs that you realize your mother forgot her blouse in your room and had left your room entirely topless. If anyone had been watching, they could have seen her bare breasts covered in your thick cum. Thankfully, the house is silent aside from the shuffling of your mother in your parents’ room and the dull, distant voices from downstairs. You make a note to give her a good deal of suggestions compelling her to be much more discreet about her new… relationship? with you the next time she’s hypnotized.

The disbelieving look in your sister’s green eyes as you arrive downstairs fully dressed and ready to leave the house makes you chuckle lightly.

“Better close your mouth, sis. You’ll start catching flies,” you tease her.

Her plush blowjob lips snap shut almost automatically. You revel in the knowledge that you’ve gotten one in over her. It doesn’t happen often.

From the way her eyes narrow dangerously, you know she’s going to try to make you pay for that later.

“Whatever, dork,” she waves a hand at you dismissively and pointedly looks away from you, as if you aren’t worth a single iota of her attention. That works for you since it gives you an excuse to ogle her big breasts that sit so invitingly in her tight green sweater. “Where’s Mom?”

“Changing. Where’s Dad, Rick, and Ronnie?” you say.

“They’re getting Ronnie set up in the car. They won’t let me touch the car seat since apparently I didn’t install it right last time,” she huffs and crosses her arms, pushing her large breasts upward.

“Ah,” you can well believe that. Smart though she may be, Tiffany was never one for following directions. She always has to try things her way and will only listen to advice once she fails and gets burned. That’s probably why she got pregnant so early, now that you think about it. And now she’s married and building a life for herself, her earlier mistake turned into a boon. You chuckle. Maybe there’s something to her approach after all.

It’s only after a minute or so has passed that you realize that your sister has been completely silent since she told you about Ronnie’s car seat.

You look at her again.

Tiffany is standing still, green eyes staring ahead. She blinks every few seconds or so, but beyond that and the subtle rise and fall of her chest as she breathes, she seems…

“No way,” you breathe. Your heart rate quickens and your cock hardens. “Um… Tiffany?”

“Yes?” she replies in a far-off voice, as if she’s taken a vacation from her own body and left it on autopilot.

You approach her slowly, looking for any sign of awareness in those gorgeous eyes of hers. Your gaze drifts down once more to your sister’s milk-engorged breasts and further still to trace the curves of her well-rounded hips.

Fuck, you really want to give Tiffany a few hypnotic commands, but you have no idea when your mother might come downstairs or your father or Rick might come back in the house. You don’t want to risk them overhearing you and coming to the conclusion that you can somehow give mothers posthypnotic suggestions; something which should be impossible if your mother’s reaction to the possibility yesterday is any indication.

“Are you hypnotized, Tiffany?” you ask her quietly.

“Yes,” she nods her head.

You bite your lip and glance around. You’re still alone with your sister in the living room.

“Is this your first time being hypnotized today?”

She nods her head again.

You reach a hand to her arm and slowly glide it down the outside of her sweater. She doesn’t react. Emboldened, you slowly inch your arm over to graze the edge of your sister’s big boobs. Though they’re clad in a bra, you can’t help the way your heart races with the reality of what you’ve just accomplished.

After over a decade of harboring a crush on your gorgeous older sister, you’ve finally gone a step further than staring at her in a bikini or catching glimpses of her in the shower. You’ve touched her; violated the distance that all siblings are supposed to respect, and in so doing you have altered the relationship you have with her forever, even if she doesn’t know it yet.

“How do you feel about me being here while you’re hypnotized?”

Your sister’s brow furrows unpleasantly, as if she’s just tasted something that didn’t agree with her.

“I don’t like it,” she says blankly.

“Why not?” you ask. You start massaging her right breast through her sweater and bra.

“It’s embarrassing. Plus, you’re touching my boob,” she says.

“But there’s nothing wrong with me doing that,” you tell her.

Her brow furrows again and you grin.

“Nothing... wrong?” she mumbles.

“There’s nothing wrong with me touching your breasts, Tiffany.”

“There’s nothing wrong with you touching my breasts,” she repeats submissively.

Your cock twitches. Holy fuck. You look around again and find yourself still alone and undisturbed with your mentally **** sister.

“I can touch you wherever and whenever I want,” you say.

“You can… no…” she says.

“You like it when I touch you, no matter where I touch you on your body,” you reach a hand around her to grab her big, soft ass.

Your older sister moans.

“How do you feel about me touching your ass?” you ask her.

She licks her lips.

“I like it,” she whispers.

“You can’t tell anyone else that you like me touching you. It’s just a secret between us,” you say.

“Just a secret between us,” she repeats readily.

“You crave my touch, Tiffany. Whenever you and I are alone, you’ll ask me to touch you,” you say.

“Ask you to touch me…”

“I’m doing you a favor whenever I touch you, especially on your breasts, ass, or pussy,” you tell her.

You hear movement from the upstairs hallway and you know you have moments before your mother comes downstairs and sees you molesting your hypnotized sister. Quickly, you give her a trigger that’ll make these encounters so much more frequent in the future.

“Anytime you’re hypnotized and within a minute’s walking distance of me, you’ll come up to me and tell me you’re hypnotized. If you’re further than a minute’s walk away from me when you’re hypnotized, you’ll call me on my cellphone. Do you understand?”

“I understand,” Tiffany says.

You give her ass a parting squeeze just as your mother descends the stairwell and finds the two of you in the living room.

“Hey baby, I’m all set to go,” she says. You look at her and almost gasp.

Your voluptuous mother is dressed in a thin cashmere sweater that clings to her huge matronly breasts like a second skin and a pair of denim pants that hug her wide hips. Her hard nipples jut against the material and you marvel at the fact that she chose not to wear a bra. Was this your doing? Have your suggestions affected the way she’s chosen to dress?

The questions in your mind disappear when you remember that beneath that sweater, your mother’s breasts are completely covered in your cum.

Your mother looks past you at your still-hypnotized sister and her eyes soften.

“Have you been looking after your sister while she’s hypnotized?” your mother asks you.

You nod at her and she beams at you.

“You’re such a sweetheart,” she mutters. “I guess your father and Rick are getting Ronnie set up in the car?”

“Yeah. They don’t know Tiff’s hypnotized, though. She fell into a trance right in front of me,” you say.

“Well I’m glad you’ve taken the initiative to be a proper man of the house. A lot of men would have just left her alone. I mean, no one would ever do anything to a mother who fell into a trance, but it’s the thought that counts,” she says.

Interesting. So the way your new world is structured clearly incorporates some form of unwritten rule that prevents mothers from being molested while under hypnosis.

“Huh. When did you get here, Mom?” your sister says. She looks between the two of you, her brow furrowed. “Shit, it happened again, didn’t it?”

“I’m afraid so, honey,” your mother says.

“Ugh,” your sister grumbles and crosses her arms, mashing her big breasts together.

You grab your sister’s hand in your own, relishing in the feel of her soft, smooth skin.

“Come on, Tiffany. Rick and Dad are probably all set up with the car,” you say.

Your sister gives you a strange look and then glances down at where your hand is grasping hers.

She smiles, tightening her hand around yours as she feels your skin with her fingers.

“Sure, bro. Let’s go!”

The three of you walk to the door and put on your shoes and coats.

After you exit the house and start approaching the parked white GMC Yukon idling in the driveway, your sister slips her hand back into yours.
