"Let's switch over to the main part now."
She straddled over him once more and raised her waist until her pussy was on top of his dick. Even though she had been much calmer compared to women Benjamin had to deal with before, she still looked quite excited right now. Her pierced clitoris was as erect as her nipples and her vagina was releasing fluids continuously, flowing down on his rod. Her smell was starting to fill the room, enticing and erotic, pushing Benjamin's tool to throb impatiently.
She took his cock in one hand and adjusted her aim before gently lowering her hips. She went very leisurely, dropping herself centimeter by centimeter, both of them enjoying the sensation of him entering her. Eventually, her butt arrived in contact with his thighs and he was fully inside her. The feeling was different from all his other experiences. She was enveloping him but the pressure was low, as if he was in a wet and warm glove. It felt comforting and reassuring but the stimulation was quite limited. This was also what he had expected. If he could fit his hand inside her vagina, there would surely be plenty of room for his penis.
He was soon proved to be deeply mistaken. She started to strongly contract her pussy walls around him and began moving her waist up and down, the squeezing on his member increasing by several times. He was taken by surprise and couldn't help letting out a groan of pleasure as she did this, making her grin cheekily, as if she had completely understood his thought process. Once again, he was proved that he shouldn't have underestimated his grandmother.
And that was not all. Instead of simply clutching her twat all the time, she began to do it intermittently, contracting and releasing the pressure, and then contracting again. It now felt like her pussy had become a living organism on its own, pulsating over his dick. Added to the combination of her moving up and down on him, he was being stimulated in a way he could never have imagined. Tight virgin cunts were good but this was something else together. As expected, experience really delivered during sex and the new sensations pushed him toward his climax much more easily than he was accustomed to.
"The way your vagina is pulsating around me feels so good. I am going to come again soon."
"Go ahead, release everything inside me, darling."
This time too she didn't increase her speed and, barely twenty seconds later, he sent a thrust into her to reach as deep as possible and let himself go inside his grandmother with a grunt, sending wave after wave of his seed into her depth. She closed her eyes to appreciate the feeling, commenting with a moan.
"Mhmm. It's been so long since I felt warm semen inside me. That's the feeling, it is so addicting. I don't know how I did without it for so long."
She continued to make her pussy pulsate until he was completely spent and took a small break after that, enjoying the sensation of her vagina being filled by both dick and cum. After that, she opened her eyes again and noted.
"You're still hard? That's incredible, love. You are like the dream lover of all women. And at least for now, you are all mine."
She smiled meaningfully and started to move her hips again before bending her upper body and going for another kiss with him. They entangled their tongues once again while she carried on with making her ass bounce on his dick for some time. A few minutes later, she suddenly accelerated her movements for a few insertions, a bit frantically, and then trembled greatly, moaning in his mouth, her pussy twitching uncontrollably and drenching his member with her juices. She orgasmed like that for a few seconds before breaking off their kiss.
"This time and last time too, I am coming so fast. It's really different to be with a man."
Benjamin felt that she wasn't quick at all, at least compared to what he was used to. If this was fast, he wondered how long it would normally take for her to cum. He guessed that she was so used to sex that it had gotten harder for her to climax.
She resumed smooching him and moving her hips and they went like this for some time. As always, it felt great to kiss while having sex and after a few more minutes, it was him again who couldn't hold it anymore and came inside her for the second time. She waited for him to finish, enjoying the feeling of his spunk inside her cunt, and commented.
"Let's change position a little."
She turned around and instead of facing him, she was now riding him with her back to him, in a reverse cowgirl position.
"This is another common position during normal sex. It is a bit less popular because partners cannot see each other's faces anymore but it allows for a different stimulation since the penis will get to feel the vagina at a different angle."
It was not his first time trying the position since he had gotten the opportunity to try it with Sasha as well as during his work the day before. It was still very pleasant and a welcome change after having been in the same position from the start. He thought it might be a good opportunity for him to move along with her and started to slowly thrust his hips up in coordination with her movements, only to be stopped by her.
"Don't, love. If you need more stimulation, I will provide it to you."
She misunderstood his intention but he didn't correct her. It seemed she really wanted the whole session to be under her control. Since that was what she wanted, he decided to let her have her way until the end. She began moving her waist at a swifter pace while continuing to make her twat pulse on his dick. It still felt amazing and both of them soon became entranced in the sex. Her butt cheeks were now slapping regularly against his thighs and the view of her behind was very erotic. After a while, she was the one who came first this time, letting out a shout of pleasure. She shuddered for a while, her fluids flowing down on the sheets. The room was now filled with the odor of their sex, each breath making them hornier than the previous one.
She rotated herself once more but only by 90 degrees this time, her side facing him, and continued to bounce on him. Her two orgasms did have their effects on her and she was also starting to really enjoy the session for herself and not just to pleasure him.
"I can't believe you are still hard after all of that. You're amazing, darling. Mhmm, your big cock feels so good inside me!"
As time went on, she was moving faster and faster on his penis, getting more and more disorderly. She rotated one more time, her other side facing him, and it felt like she was now going full strength on him. He was surprised by her stamina, which was really good for someone her age. Soon, she was close to another climax and she rotated one last time, facing him just like at the start.
"Yeess! I am going to come again! I can't believe a cock will get me off so many times!"
"I am close too!"
"Good, come together with me, dear!"
She impaled herself a few more times on him before suddenly trembling, her pussy contracting strongly on his member and her face contorting in great pleasure, letting out her feelings with a squeal.
"Ooooohhhhh!"
Her walls gripping him like a vice also became the breaking point for Benjamin, who cummed together with her, his sperm exploding deep into her insides one last time with a satisfied groan.
Once their orgasms ended, his grandmother flopped powerlessly on the bed, his dick getting ejected from her cunt. Her head fell behind his and her cunt started to let out his three ejaculations worth of semen on the sheets since she had relaxed her pussy muscles. He aligned his body with hers and took her into his arms, cuddling with her. She smiled at his gesture and feebly returned his hug, looking tired after so much activity.
