A special massage, Part 2

John’s cock immediately responded to the proximity of their bodies. Lilith felt it throbbing against her panties as she settled into place. The thin fabric of her underwear was the only barrier against something truly forbidden. She knew she needed to do something more than hold her body against his to get him back in the mood though. She gently took John’s head between her hands and guided it towards her own. Her tongue thrust between his lips as she moved in for a kiss.

Her son's eyes widened as she probed her tongue into his mouth, but he quickly relaxed and allowed it to happen. Lilith took the initiative, not knowing if her son had ever passionately kissed a girl before. She ran her tongue along his to coax it out, then sucked on it as it responded. After a few cycles, John followed her lead, and their tongues began to dance together as they sucked on each other’s tongues and lips.

Lilith felt all the stress of her poor performance melt away in John's mouth. Her hands, now remembering the motions she’d spent all day practicing, moved down to rub his shoulders in what Lilith felt could finally be called a massage. John, in turn, brought his arms up around her, and slipped his hands under her panties to grab her ass. She moaned as he touched her, encouraging him to keep going. His groping and squeezing sent jolt of pleasure through her body, and she poured that feeling into the passion of their embrace.

John had been taken completely off guard by his mom’s kiss. The moment she’d started pouring oil down her front, he knew she had something sexy planned for him, but he didn’t expect her to dive right in to making out. The kiss was incredible, more passionate than the doctor’s and more experienced than his exe’s. He couldn’t help but melt into it. His hands instinctively went for her ass, wanting to feel as much of her pressed against him as possible.

Lilith’s body was intoxicating. Everywhere their skin made contact sent jolts of pleasure firing through his body. The sensation was overwhelming. John couldn’t contain himself any longer. He felt the orgasm approaching moments before it ripped through his body. His body spasmed as his seed spilled out in waves into whatever gaps it could find between their bodies.

As the pleasure receded, John felt himself flush with embarrassment. He couldn’t believe a single kiss had been enough for him to blow his load. It had been his most humiliating performance since starting his treatment. Lilith somehow hadn’t noticed yet, still completely engrossed in their kiss, but once she did it would be an end to the moment. ‘It happens to everyone’ she'd say, to rub in his failure as a man.

As the minutes passed by however, John felt no indication of starting to go soft. His whole body remained charged up with arousal and his cock still twitched with need. Deep within he began to feel the slow, unmistakable build-up to another orgasm. He had no idea how, but by some fluke his body was ready to keep going and he wasn’t about to turn down that blessing.

Lilith was still oblivious to John's embarrassing accident. If he played his cards right, she'd never need to know. He just had to clear away the evidence. Carefully sliding his hands out of her panties, he began rubbing his jizz into her body. He tried to spread it evenly to help it soak in, but found most of his attention went to her breasts. Earlier when she’d come into his room, unknowingly wearing the bra he’d used as his cum rag, it had been such a huge turn on for him. The thought of her walking around, completely unaware that her tits were covered in his seed as it slowly soaked into her pores was so hot, he couldn’t pass up the chance to cover them in more. Still lost in whatever fantasy she was having, Lilith moaned into his mouth as his hands brushed across her body.

John couldn’t see how well he’d rubbed the fluid into her skin and the massage oil made it difficult to feel how much was left. Nevertheless, he had to stop at some point and he desperately wanted to sink back into her embrace. The whole time Lilith had been lapping at his face in a show of passion and John had been keeping up to keep her from breaking from her reverie, but with his task complete, he could put his full focus back into enjoying their kiss. He was feeling much more relaxed now. Having came already, he was sure he could endure the pleasure as long as he wanted and enjoy whatever his mom had in store for him. His hands slid back towards their place on her ass. Of their own accord, they started to push aside the fabric of her panties, wanting to fully enjoy what lay underneath.

***

It was only as John tried to slide her panties down that Lilith snapped back to reality. She grabbed his wrist to stop him. Her panties needed to stay on. It was proving far too easy for Lilith to lose herself in John’s touch. The garment was their only barrier from doing something she couldn't let herself do. With great regret she recalled the purpose of their time together wasn’t to make out and pulled her face away from John’s lips. Gratefully, she found, the kiss had put them both back in the right state of mind to enjoy the rest of their massage.

Lilith’s body was still slick with the massage oil. It had started soaking in, rendering her skin extra sensitive. It was time to make full use of her body. Supporting herself on her elbows and knees, she pressed her body close to his and began to rub them together. The slippery oil allowed her tits to slide effortlessly over John’s skin. Her nipples hardened under the stimulation sending pleasure coursing through her. Lilith ran down to the bottom of his ribs then circled around the other way. As she reached his chest, she looked up at him and met his eye. His gaze burned with unbridled lust that sent a shiver through her own body.

Lilith noticed something at the edge of her vision. Looking down, she found her bust had become covered in the same goo she’d found coating her bra earlier that day. Her sweat and the massage oil must have drawn it out of her skin again. John noticed it too, and his eyes locked on the slime smeared over her tits.

“I’m sorry honey. My body’s a bit gross today, I’ll have to switch out my body creams.”

She pushed herself up from John, not wanting to get any more of it on him than she already had. There were streaks of it here and there on him where she had rubbed herself across his body. She couldn't stop the action to get herself cleaned up, so her only choice was to rub it back into her skin instead. John’s eyes lit up and his cock twitched as she started doing so, clearly finding the action incredibly arousing. Once again, her heart skipped a beat as John showed appreciation for even the grossest aspects of her body.

Lilith couldn’t help but want to please the only man to show her the attention she craved. She needed to make it the sexiest show possible for John to enjoy, letting her boobs bounce and jiggle as she groped and rubbed at them. The increased sensitivity from the massage oil turned Lilith on more as she pawed at them. Once the goo coating her breasts had soaked in, she scooped up the streaks on John’s body and rubbed them into herself as well. By the time she was finished, her bust reeked of sex; a smell that pushed Lilith’s mind into a sexual frenzy. For a second she could have sworn it smelled like cum, but that was impossible. John had yet to ejaculate, and the goo had come from her own tits.

With the slime all soaked back into her body, Lilith poured a fresh coat of massage oil down her and John’s front. She began to repeat her earlier motion, rubbing her body in long, sensual laps across John’s skin, each time sweeping herself lower than before. John’s body began to shiver under the touch of her skin, reacting stronger than any massage she could hope to achieve with her hands.

Before she realised it, she’d slid her body down into John’s lap. His cock poked into the valley of her cleavage, threatening to **** its way between them. He held his breath, silently willing his mother to continue her journey down his body. A jolt of pleasure ran through her body as they made contact. Something inside her begged her to continue and swallow her son’s cock between her tits, but she didn’t want to go there yet. Once she started stimulating his cock, she knew the scene would quickly draw to a close. She wanted to draw this out as long as possible.

The doctor had said she should be able to make him cum without touching his penis. She needed to make up for her earlier blunder; She had to at least do this right. He was a premature ejaculator, and she was a mature slut. He hadn’t announced himself masturbating in several hours now, so he should have been ready to come on a hair trigger. There was no reason she shouldn’t be able to get him to without touching his cock.

Yet as she continued to rub her body across his, John never for a moment showed signs of approaching orgasm. There was no tenseness in his abdomen like he was holding back his ejaculation. Niggling doubts started to eat at Lilith’s mind. Was her massage not good enough? Was her body not sexy enough to make even her son cum for her? As the worries grew, she asserted all of her efforts into getting him off.

“Does that feel good honey? Don’t you want to cum for mommy? Please cum for me” she started to plead him in the sultriest voice she could manage as she became more ****. “I want your delicious cum all over me so, so bad. I’m your little cum slut, darling.” John responded well to her dirty talk, so she the her pride to the wind. "Please bless your fuck-doll mommy with your jism, honey. Dump your load all over this dumb cum slut. Please, I need it so bad." But for all her effort, there were still no signs of him approaching the edge.

Lilith’s frustrations continued to grow with every passing minute. Every time she brought her body down to John’s lap, she found it took greater and greater restraint for her to pull herself away again. Part of her longed to let go and take the easy way out. She soon found her body once again come to a stop by John’s lap, as though some invisible **** had drawn her in. She couldn’t bring herself to continue. Her body locked itself in place as she mulled her actions over.

The slut inside her ached to worship the cock of the man who idolised her body, but it also wanted to prove to herself that her body alone was sexy enough to get him off. The mother inside her wanted to give John what he needed to make up for all the discomfort her massage had brought him, but it also wanted to take John’s treatment seriously and make the massage special for him. She was so deeply conflicted, but she knew that giving in to her temptations would not be good for either of them.

It was clear her current technique was not good enough however and was just giving her ample opportunity to lose herself to temptation. She needed to gather herself and come up with a new plan of action. Just as Lilith was about to pull herself from John’s lap for the last time however, his impatience got the better of them, taking the choice out of her hands. He grabbed hold of her shoulders and pushed down. At the same time, he rolled his hips upwards, and his cock penetrated the gap between her tits.

As John’s dick found it’s home between within her cleavage, a strange sensation ran through her. She felt a knot loosen in her chest, one that she’d been bearing inside her for days now, one that had weighed down on her as she tried to sleep, and with its absence her entire body felt at ease. It was like she’d been reunited with a missing part of herself. It made no sense to Lilith, but she had no time to think on it. She was so high-strung with arousal that the sudden release of tension pushed her over the edge, and she started to orgasm.

“Oh fuck! Fuck John, yes!” she moaned as the pleasure overtook her. John watched on in shock and awe as her body responded to his simple act of penetration. Lilith squeezed her tits hard around his cock, refusing to let go of the thing making her feel this good, as the rest of her body trembled against his.

She had never orgasmed during a titty fuck before, let alone before she even started one. A small part of her was concerned it was her son that elicited such a response from her but the greater part of her was just **** for more. His cock felt so right within her bosom that she couldn’t bring herself to part them. She couldn't allow that knot to reform in her chest.

Lilith’s body moved on its own to assume a proper position. It was inevitable at this point. She needed him to fuck her fat tits. That’s what she knew deep inside herself. It was the only way to release herself from the tension that had been plaguing her for the last few days. John’s cock was the most important thing in her world right now. She needed it so bad, and she wanted nothing more than to worship it with her tits.

By the time she had moved into a proper position between his legs, John’s cock was completely submerged within her titty flesh. She could feel it twitching in anticipation. John’s excitement was obvious and infectious. This was exactly what his body desired since she’d begun her massage, and she wanted to give it to him so bad. The thick odour of sex emanating from her cleavage clouded her mind with lust.

‘Before his mother, I am a slut.’ Lilith’s mantra played on repeat in her head to justify her actions. It suppressed any trepidation she had to what she was doing. ‘Women only exist to pleasure men.’ She was only surrendering to her natural instincts as a slut. She was simply fulfilling her purpose.

“Fuck, mom. That feels so good” John moaned as Lilith began to rub her tits against his cock. His immediate response to the pleasure was already stronger than anything she had done to him to this point. It made everything that had come before feel irrelevant in comparison. Why waste her time beating around the bush around when the direct approach to servicing a man was the most effective. On her knees, serving a cock directly with her body. That was where she felt most at ease.

The oil soaked into Lilith’s flesh made her skin feel so tingly and sensitive, that the pleasure her tits imparted on John’s cock reverberated through her own body in harmony. Lilith had never felt so attuned with a man before. She could feel the pleasure of John’s building orgasm coursing through his body as if his nerves were her own, and she knew that when he reached his peak, she would crest it with him.

“Do you like that baby? Do your mommy’s fat titties feel good on your big cock?” she goaded him on shamelessly.

“Fuck Mom. I can’t hold it. I’m gonna cum.”

“Do it baby. Cum all over mommy’s big titties.”

John’s cock was twitching fast now, and his climax was moments away. Lilith gave her tits a few strong bounces on his dick, pushing him hard over the edge. In the same moment, she squeezed hard on her breasts and pinched her nipples firmly with her thumb. They both hit their orgasm together. Their moans rang out in unison as a fountain of semen shot out from Lilith’s cleavage, covering every inch of her face and chest as it fell back down. Even as she came herself, she continued to rub his shaft, milking his cum with her tits as they started to come down from the bliss.

Once the last vestiges of their orgasms played out, Lilith finally came to rest, completely exhausted by the ordeal. The stench of sex was all around her, but for now Lilith felt fulfilled. The pair lay still for several minutes, as John’s erection slowly softened between her breasts. Their heavy breaths were the only sound to be heard.

As the cloud of lust in her mind began to fade, Lilith began to feel a sense of guilt at what she’d done.

“Oh my God John. I’m so sorry.”

This wasn’t how it was meant to go. She’d made a total mess of the massage she was supposed to give him, if any part of what she’d done could be called a massage. Lilith had been determined to do it properly, to make up for all the times she’d failed to follow the doctor’s instructions, but she’d let her own desires take over and ruin the moment for him. All of a sudden she felt all of her failures over the last few days begin to well up.

“It’s okay mom. I-”

“No, it’s not okay John” she interrupted him. “I mess everything up. I slipped out of the shower, I slept through one of our sessions together, I skipped the one from this morning, and now I can’t even give you a massage properly. I keep messing up these very important parts of your treatment. If your never cured of these unhealthy desires, it would be all my fault. I’m failing you as a mother.”

John’s mouth hung open, completely unaware of where her feelings were coming from. The doctor had been quite clear with Lilith. In order to fix John’s incestuous desires, she had to follow her instructions. Sure, she’d managed to get John off just now, but not in the way the doctor had told her to. She had just as likely cultivated John’s attraction towards her with her actions as worked to fix them. It was vital she did things the way the expert told her to, or she was just making things worse. So far, she’d only managed to follow her instructions once without screwing it up somehow. That just wasn’t good enough when her son’s health was on the line. His lust for her was stronger than ever, and it was all Lilith’s fault.

She pushed herself up on shaky legs and turned to leave. She knew if she remained, John would attempt to console her, but she didn’t deserve that. She ignored him as he attempted to stop her and headed for her bedroom. As she went, words from the doctor echoed in her head. ‘Sluts live to bring pleasure to men. They aren’t really good for anything else.’ That felt especially true to Lilith now. Perhaps all she was really good for was making John cum.

Lilith shut the door behind her and collapsed into bed. There was no sense in wallowing in her failure. She just needed to sleep it off and come back at it with a renewed sense of resolve. She couldn’t afford to mess up John’s treatment anymore. She had to follow the doctor’s instructions perfectly from now on.

Lilith found sleep coming a lot easier than she had the last few days. The knot in her chest that had left her so restless had seemingly lifted completely as she pleasured her son. She didn’t know what it meant, but she’d have time to think on it later. For now, she was just thankful to finally get some restful sleep.
