Mrs. Robinson: by Simon & Garfunkel
Hide it in a hiding place where no one ever goes
Put it in the pantry with your cupcakes
It's a little secret, just the Robinson Affair
Most of all, you've got to hide it from the kids
Misses Robinson laid back with her thick thighs spread wide as she savored the sensations of Jacob Jones pleasuring her with his lips and tongue. The callow, rather awkward eighteen year old was no longer hesitant or clumsy. He was no longer the inexperienced virgin that he had been at the beginning of the summer. He was no longer mystified by female anatomy. Although he was obviously aware that the anatomy of a woman who was literally old enough to be his mother was somewhat different from that of a girl his own age, he was far to considerate and smitten with her to be reticent. She had been his first. She had been his first for almost everything, serious kissing, petting and oral, before finally taking his virginity. Now with his departure to college eminent, he was probably more sexually experienced than most of his peers. He had become almost as adept at pleasuring her as her husband had once been and had finally become, once again.
This last thought evoked Rachael Robinson's guilt. However; it also provided a pretext to justify or at least rationalize her adultery. A wife shouldn't have to be subjected to the chronic complacency that might motivate her to cheat on her husband. Of course Mister Robinson had been suffering from difficulties. However; his doctor had cautioned that given his cardiovascular issues, those difficulties were not so severe and chronic to warrant a prescription. The doctor had even suggested alternative activities.
Rachael felt first one, then two, then three fingers being inserted deep into her vagina. Those fingers sought out her gee-spot as Jacob's lips and tongue continued to pleasure her labia and clitoris. Misses Robinson's large, somewhat saggy breasts jiggled embarrassingly as her body trembled in response to another orgasm.
Jacob obviously recognized that the time was right. He withdrew his fingers then kissed his way up her gently rounded belly. He only briefly suckled at her breasts. He didn't tarry. While he adored her big breasts, he was no longer obsessed. Neither of them needed more foreplay. As she felt Jake's penis slowly and gently but confidently penetrating between her labia, Rachael became acutely aware of the lingering flavor of his semen in her mouth. She had given him a blow job barely an hour ago. Unlike her husband, he had the recuperative powers of youth.
For only a moment, Rachael considered the fact that Jake wasn't wearing a condom. He never did. She never asked him to. She had always hated those damn things. However; Jake also hadn't gone to the bathroom to pee and wash his penis as she had taught him that he should. Along with biology, Rachael taught sex education at school. She knew that she was breaking almost all of the approved rules with Jacob just as she did with her husband. In spite of her alleged negligence, she only had three children, all of whom had been intended. She had often been shamed by the hypocrisy of denigrating the time honored rhythm method as well as the pull and pray method that could serve almost as well as condoms, the sponge, a diaphragm. She had never been willing to risk the side effects of the pill.
Rachael had no doubt that the penetration of Jake's penis into her vagina was being lubricated by a thick film of semen. Far more semen remained in his urethra to be gradually discharged along with his precum during their impending copulation. His precum would contain, many thousands, maybe millions, of sperm. Rachael glanced at the calendar on her nightstand. The Thursday two weeks ago had been circled in red to remind her of when she had last started menstruating. The timing couldn't be worse. However; she had seldom been asking Jacob to take such extra precautions except during those first, few, tentative, guilt ridden weeks. She had gotten away with it before.
Rachael's body eagerly responded to the vigorous but now adept thrusting of Jacob's penis into her. She had never been callous enough to wound his male ego by revealing that her husband's penis was at least an inch or so longer as well as thicker. Jake had remained a virgin during his high school years in part because he was acutely aware of the fact that he wasn't well endowed. In spite of his greater size, Roger Robinson had on occasion commented on the fact that Rachael wasn't quite as tight as she used to be. Jake had never wounded her ego with such observations.
Jake's lips and tongue were as usual to preoccupied with passionate kissing to allow either of them to talk. She could feel him shifting his position, adjusting the angle of penetration, to give her pleasure in spite of his less than spectacular endowment. Soon she could sense that he was restraining his own impending orgasm. He had plenty of time. Aside from her recently performing fellatio on him, they had fucked much earlier when he arrived that morning to finish the wall. She had no doubt that as had become usual, he would succeed in bringing her to orgasm, again.
Rachael's body trembled as she orgasmed again. She instinctively wrapped her thighs around Jake's hips, hugging him close. She felt him trying to pull away. The spasming of her pelvic muscles had finally pushed the young man over the edge. Rachael only reluctantly loosened her grip so that Jake was merely hobbled rather than restrained. That precious first spurt of semen was already squirting from his urethra as his pink glans emerged from between her labia. As had recently become her habit, she playfully impeded his attempts to fully withdraw so that the remainder of his semen spurted dangerously into her unshaven, jet black pubic hair and between her distended labia. Jacob yielded to his instincts as well as her encouragement by plunging his penis back into her vagina. She could feel him throbbing inside her as those last few, feeble spurts of precious semen were unleashed so dangerously close to her unprotected womb.
As their passionate kissing continued, Rachael contemplated her recklessness. The fault was really hers rather than Jacob's. Perhaps Jacob had inspired her, but she had finally recovered from that traumatic miscarriage. The increased diligence bordering on compulsive obsession that had alienated her husband had abated. However; she rationalized that they really wasn't being that reckless. She was also getting to an age when she wasn't as fertile as she used to be anyway. It would be okay.
