The Omnistore System

"Given that you've already given him a blowjob once or twice, I believe," Maria mentioned, glancing down at a streak of white trailing from the corner of her mouth.

Keith nodded, his member in her hands, which she continued to stroke, keeping it firm. "So, there's not much for me to teach you, but I can certainly refine your skills," Maria said proudly. "Especially in pleasing my own son's dick. He's quite fond of my technique, you know?" Kevin smiled, recalling her adeptness at handling his ejaculations.

Keith gazed at the duo with a perplexed expression. Their relationship was beyond her comprehension, even for someone with her level of openness. She'd had seen this scenario of mother and son having sex in a porn, even pleasured herself to the thought. Yet, witnessing it in real life, and seeing them revel in it, left her with a mix of emotions—primarily a desire to pleasure herself. Her request for a blowjob lesson from Maria was partly to stoke jealousy, believing it would heighten her arousal.

However, the notion of Kevin being her son was unexpectedly more stimulating for now. The idea of getting instructed by Maria on pleasuring her own son's penis turned out to be the most arousing of them all.

Maria glanced at Keith kissing Kevin's penis, noticing her fixation on its head before starting her lesson. "First thing about giving a blowjob is eye contact... so try to keep looking into his eyes and convey your intentions with his penis through them..."

Keith followed her guidance, shifting her gaze from the penis head to Kevin's eyes. However, now with a video call screen showing Maria looking at her, their eyes met. Keith's contemplative expression turned teasing as Maria's face grew increasingly jealous. Despite that, Maria continued to instruct. "Don't just kiss it's head, kiss all around it...Start by kissing his balls, it's part of the equation too, don't forget to show them some love. Lick them, put his penis on your lips, keep stroking it... ohh, maintain eye contact just below his penis... ahhh..."

While giving instructions, Maria began to moan, feeling Keith's gaze directed at her.

Finding it oddly arousing to watch another woman pleasure her lover's penis, she felt a mix of jealousy and arousal. 'What am I doing?' she questioned herself, never expecting to feel turned on by witnessing someone else perform oral sex on her partner, let alone teaching them how to do it.

"Put them in your mouth... ahhh, stroke his penis... ahhh, with your hands... ahhh..." Despite these thoughts, she couldn't resist. Kevin smiled amusedly at his watch screen, observing Keith grinding her hips while maintaining eye contact. Her ample breasts swayed gently, nipples hard, and he noticed the bite marks around them, longing to have them in his mouth. 'Damn... I miss her soft body,' he thought, reminiscing about the days when Maria stayed home, glued to him, naked all day, her soft curves against him, her breasts in his hands and mouth, her lips always tantalizingly close.

In the hours before leaving home, his hand practically never left her body. Well, except when Riya was there, and even then, it was solely to work on pleasuring her like a passionate scientist.

As he reminisced, Maria had already progressed further in her lesson, teaching Keith how to deepthroat. Since Keith already knew how to do it, there wasn't much left to cover. Maria proceeded to instruct on how to receive semen in the mouth or swallow it. "With this, you'll be able to make him cum with some effort," Maria explained, glancing down at Keith's moving face. "You can either let him ejaculate in your throat, mouth, or on your face... whichever you prefer. But I usually ask him where he wants it, so you can do that too."

Keith wasn't fond of the taste, so having it in her mouth was a big no for her. Swallowing it down her throat was acceptable, and she had experienced a facial before, but following her instructor's advice, she silently asked Kevin with her eyes what he preferred.

Kevin smiled, nearing the edge, and as he reached that point, grabbing her head gently, he said, "On your face..."

With a smile, Keith withdrew his penis, saying, "As you wish..." His lips were moist as she began stroking his saliva-drenched shaft and sucking his testicles. Meanwhile, Maria, now providing detailed instructions, was also pleasuring herself, fingering her own vagina while requesting, "Yeah... ahh... Kevin, can I cum now?"

Kevin, preoccupied with his own impending orgasm, responded, "No, not yet... Wait for me to finish first..."

Maria continued to stimulate herself vigorously, changing positions from riding a pillow to spreading her legs and raising them high against the wall. She displayed her unshaven vagina, fingers moving rapidly in and out, creating squishing sounds. Her eyes filled with desire as she gazed down at Keith, who was stroking his penis and sucking on his testicles. "Ahhh, I'm..."

Kevin wore a wide grin as his hand gripped Keith's head. She showered his balls with affection, using her tender lips and tongue, sucking, licking, and cradling them while maintaining a steady stroke on his penis. Soon enough, his climax erupted, a white, blurry substance shooting out forcefully—some splattered on her hair and bed. With instinctive precision, Keith directed the remainder of the orgasm toward her face, continuing to stroke and guiding the semen across her forehead and cheeks. She closed her eyes to shield them from the fluid.

In slow motion, Kevin observed his semen coating her entire face, culminating with the last shot landing on her lips. She took it into her mouth, eliciting a moan from him, and then sucked out the remaining residue.

Kevin breathed heavily, peering down at her. Her eyes remained shut, mouth open, playing with his semen using her tongue. Suddenly, she swallowed it down. Kevin observed and grinned widely, finding it more arousing.

Keith herself wasn't sure why she opted to do this, but she knew it would please him, so she did it without much thought.

Maria, witnessing this, felt the throes of orgasm building within her core. However, she couldn't reach climax without Kevin's permission, so she pleaded, "Kevin... ah, please... let... let me cum..."

Kevin smiled as he watched Keith clean her face and scoop his semen with her finger, putting it in her mouth. "Okay, you can cum now..."
