The expression on 66 year old Elsie Comstock's face was an accurate barometer on how the stunned woman felt when she figured out exactly what her grandson Billy had in mind, yet she knew in her heart that she had only herself to blame.
The widow had enjoyed a perfectly normal relationship with her daughter's son Billy, a charming and adorable boy who was 19 and just starting his second year in college, but that all changed that one night when the boy came across town to pay her a visit.
It was the alcohol's fault, Elsie reasoned. She hadn't been expecting company and had been taking a nip or two of the brandy she used to warm her insides and dull the pain of being alone and lonely.
Billy had been different that evening when he spoke to her and his hands were - well, he was always an affectionate lad but that night his hands were more affectionate than a grandson's hands should be.
The next thing Elsie knew Billy had brought her into the bedroom and was undressing her, and the elderly woman made no effort to stop him. The alcohol may have dulled her senses and impaired her judgement but not enough to make her less embarrassed about having her grandson see her naked body. Billy didn't care though and kept telling her how sexy she was and how much he had always wanted her.
Elsie could have stopped her grandson because while he was larger than the slender senior citizen the difference was not that great, and besides Elsie knew that Billy would never hurt her for anything in the world so if she resisted for real he would have stopped.
In her mind Elsie was trying to tell him to stop but somewhere between her brain and her vocal chords the message was lost. Had she led him on? Had all those hours of reading those naughty stories on that Literotica website warped her judgement?
Elsie Comstock liked the spicy tales of women her age doing things she used to do so often with her late husband and had especially enjoyed the tales of young men with women her age, although to Elsie it seemed unlikely that any young fellow would lust after her like that in real life.
And then there were those awful stories about grandmothers and their grandsons. The first time she saw some of the titles she shook her head, revolted at the suggestion that there were grandmothers doing such things with their babies, and just because the boys were 18 didn't make it right.
So she passes the Incest stories at first, but as time went on she began to get curious. The curiosity got the best of her, until not only did she read the occasional tale of Grandmas and Grandsons being intimate, she found herself searching them out.
When Billy showed up at the door that night Elsie had been at the computer with her brandy reading an especially naughty story, and as if he had sensed her vulnerable state of mine she soon had been maneuvered into her bedroom by her grandson.
Billy's hands were everywhere at once, sliding into the folds of her bathrobe and groping her through the nightie she was wearing while her hands were on the boy's shoulders, trying even less than halfheartedly to ease him away from her as her back pressed against the wall.
"Want you so bad Grandma," Billy was saying, his eyes wild with a look she had never seen before. "Always have and you've known it too."
Had she? She thought it was her imagination when he would see him looking in her direction when she would bend over, not believing that her grandson would be trying to look down the front of her blouse, especially since there was so little to look at.
Yet now Billy's hands were on her breasts, roughly kneading the low-hanging orbs through the satin, and Elsie cursed her body for betraying her as her nipples blossomed in Billy's palms while he nuzzled into her neck.
Her robe was now on the carpet, Billy having worked it off of her as she squirmed against the wall, and although there was no light in the bedroom except for what came in from the hall it was still too bright for Elsie who felt naked clad only in the modest nightie.
"Tell me you want me Grandma," Billy was mumbling as he leaned lightly into her and chewed on her neck.
"Billy - please," Elsie almost sobbed as she felt his hardness press against her while Billy's hands moved up and down her sides, pausing to let his thumbs stroke the moist peach fuzz under her arms as Elsie shivered.
The hardness. Elsie's head was spinning as she recalled last summer when Billy had stayed with her for a while as she recovered from wrist surgery and she had accidentally seen her grandson naked after he showered.
That HAD been an accident, Elsie had kept telling herself afterward, and while that was true it was true only to a point. She could have turned away but she hadn't. Instead she had stayed and watched as Billy dried off oblivious to his audience, and as her grandson dried his hair she looked at the lad who was now a man even if his 5'6" frame was still boyish.
Oh, Elsie's eyes did take in all of Billy as she saw him naked for the first time since the days 18 years ago when she had changed his diapers and powdered his bottom, smiling as she saw his bushy armpits and furry calves which looked out of place on his boyish body, but most of her attention had been focused between his legs and what had certainly changed the most over the years.
Elsie had been stunned when she saw her grandson's flaccid penis hanging there under the nest of brown curls, and while she hadn't seen all that many of them - only one other man since she was 18 herself - the sight of Billy's over-sized organ nearly made her faint from shock.
Afterward Elsie had told herself that it was the fact that Billy was such a slight lad that made his penis look so large on his frame, but that was only part of it. Billy's penis was quite large, as was the scrotum that dangled behind it, and although Elsie thought that her late husband was nicely endowed frankly he paled in comparison to Billy.
Now that very same penis was not soft and harmless but hard and angry, and when Billy grabbed her hand and brought it down, while he might have pushed her hand onto the bulge at first he didn't make her squeeze it. Elsie shivered when she felt the blood making the organ pulsate in her grasp.
"Feel it Grandma? Feel how hard my cock is?" Billy was asking, and as if he was reading her mind he continued. "Remember that time last year when I took a shower and you peeked in the door at me?"
"What?" Elsie mumbled as she felt her nightie being lifted.
"You know Grandma - when I was drying off and you watched? I kept drying my hair and hoping you would come down the hall, hoping that you would see me and want me like I've wanted you all these years," Billy explained. "I wanted you to see that I wasn't a little kid anymore. Did you like what you saw?"
"Billy please - I'm weak," Elsie said just before Billy's lips covered hers, and then his tongue was sliding between her lips as her nightie was pulled off her bony shoulders and quickly dropped to the carpet.
The room spun around the senior citizen as her grandson's mouth and hands were everywhere as once while he moved them both over to the bed with tiny steps, and as she was eased down to the fluffy bedding Elsie stopped struggling.
"Oh man - I knew you'd have a hairy pussy," Billy was saying as she moved under her so her skinny legs were over her shoulders, his voice becoming muffled as his face ducked between her legs, lapping at her sex which was wet before his tongue even got there.
"Billy," Elsie cried as she looked down at the back of her grandson's head wiggling as he lapped her womanhood like a frantic puppy while working his own clothes off at the same time.
