Of course not

“Of course not, Mom,” you say quickly, pushing your chair back and patting your lap. “Make yourself comfortable.”

“Thank you,” Melanie replies gratefully as she gingerly raises one leg and steps over your thighs. You watch with rapt attention as her exposed breasts jiggle with every movement, and your erection grows so uncomfortable that you shift in your chair to try and get it into a position that isn't so restrictive.

Melanie glances downward, but doesn’t react to the unmistakable sight of your raging hard-on. She merely smiles and sits down on your lap, avoiding contact with the tent in your pants. Since she's not much shorter than you, her tits end up level with your head. With this up-close view, you can really appreciate how deliciously creamy they look, each one capped with a magnificently-pink nipple begging to be sucked.

You feel her gently grasp the nape of your neck with her right hand. With the other she hefts her left breast, bringing it towards your face.

Holy shit... Her husband is right there, you think. He's just sitting there, eating breakfast... Not even batting an eye while his wife tries to breastfeed a grown man in their own home.

“Say ‘aaah,’” Melanie says in a sing-song voice, leaning in to push her nipple against your lips. Your eyes are locked with hers as she caresses your neck lovingly, and you part your lips to allow her teat in.

“There, that’s a good boy,” she says sweetly, gasping a little as you roll your tongue around her nub and teethe the skin of the areola. You reach up and grab her other tit, beginning to fondle it liberally as you suckle. Soon her sweet liquid flows into your mouth, and you moan into her breast with delight. Somehow this feels more satisfying than most of the sex you’ve had so far, and it keeps getting better by the moment.

"Good boy," Melanie giggles, scratching your head playfully as you continue biting and tugging at her nipple. “...Although, you’re much naughtier than your younger sister.”

“He’s a boy! Of course he likes titties,” Greg pipes up.

“He definitely takes after his father there!”

Another wave of pleasure washes over you as your "parents" share a laugh. You really do enjoy the way they treat you; it's truly as if you can do no wrong!

“That’s enough for now, Sweetie," Melanie says after a while, patting your head and giving it the softest push in an attempt to coax you off. "Leave some room for breakfast... Milk alone isn't enough for a growing boy!"

But you refuse. You lean in and suckle more enthusiastically, and take the chance to grab her plump asscheeks and pull her onto your erection.

"John!" Melanie hisses under her breath as you start feeling her up and grinding against her just outside her husband's line of sight. "Ugh. Fine, a little more."

Greg laughs heartily, oblivious to what just transpired.

After several minutes of additional affection, you give her nipple one last lick before obeying, pulling away from her luscious breast. You don't want to cause too much of a fuss, and she's right, anyway; you can’t live off of her breast milk, no matter how enticing that sounds...

...But that doesn’t mean the fun has to stop.

“Give me a kiss,” you demand.

“Sure, Darling,” Melanie replies, kissing you on the forehead.

“No, no. On the lips--Like the ones you give Dad.”

“Oh, um... Alright.”

Melanie licks her lips, then smiles at you with a dangerous glimmer in her eye. You feel almost threatened by her expression, like you're prey face-to-face with a predator.

Before you can react, she leans in and captures your lips with her own. Her hands travel to the back of your head, grabbing fistfuls of your hair as her tongue slips into your mouth. She engages with you passionately--So passionately that you’re caught totally off guard.

The kiss is intoxicating and overwhelming, but you can’t find it in yourself to resist: this is what you asked for, after all. Your arms rest lamely on her waist as she parts from the kiss briefly to breathe, giggling sweetly at your expression before leaning in again. She kisses you deeply and thoroughly, moaning into your mouth. They're sounds of lust and satisfaction, clearly meant to excite and arouse a man.

It seems like an eternity passes before Melanie finally lets go. You stare at her in a daze as she licks her lips again, watching you closely.

“I feel jealous,” you hear Greg say, from somewhere in the room; you're too distracted to even care. “...And really turned on.”

“Oh? We’ll have to do something about that,” Melanie replies in a sultry tone, her face flushed and her eyes still on you. “But only if you take me out on a date, Dear. Maybe John can take care of his sister for a while?”

“Sounds good! Think about where you want to go, and I'll pick you up on the way home from work.”

“Okay, Dear,” Melanie says happily, shifting as she prepares to climb off of your lap.

You blink and sigh, coming out of your stupor. A wry smile creeps onto your face as you realize you've just been given your first chore; you're certainly a member of the household now.
