"I used my saliva as a lubricant and I am now moving my palm up and down on my penis to stimulate it."
She nodded approvingly at his words but looked like she wanted to hear more so he had to think about things to add. He slowed his movement to explain the process step by step.
"I start from the root, like this, and move my hand up until my thumb and index fingers reach the separation between the verge and the glans. This part being stimulated feels good so I stop there and move my hand down again. I repeat the process like this many times."
It seemed even she didn't expect so many details and was fascinated by the view. She was also getting more excited, her thighs rubbing against each other a little.
"From time to time, I go all the way up and close my hand to stimulate the top of my glans. This also feels good but because I need to close my hand, this is like a small deviation from the normal movement, to give a different stimulation and keep the whole thing interesting."
Now he resumed showing what he was doing at his usual speed, alternating between many strokes going only part of the way with one going all the way and surrounding his shaft entirely from time to time. The more he progressed, the more lecherous Sasha seemed to become. At some point, it felt like she couldn't hold it anymore and simply put a hand in her panties to start masturbating at the view. After everything they had done together, she didn't feel ashamed about these sorts of minor things anymore and had no hesitation in doing what she wanted with herself. She moaned and panted, her gaze fully focused on what he was doing. This was a very welcome development for Benjamin. Even though what he was doing felt good, not having any external stimulating factor meant that he would have to either rely on his imagination or spend a lot of time and effort to get off. That would have been a shame with a woman in front of him.
"Can you remove your pants and panties?"
She nodded and swiftly removed those, immediately sending her hand back to where it belonged when she was done. He was now able to see what she was doing. Her thumb was fondling her clitoris while her index and major fingers were thrusting inside her pussy, the whole thing producing some erotic noises. Getting excited due to getting a better view of her schlicking, he slowly accelerated his movements. As if in sync with him, the nurse also did the same, the two of them getting more and more heated in their act.
He noticed her climaxing once after a minute but she immediately continued with her masturbation, as if nothing had happened. A few minutes later, he was the one ready to go.
"I'm getting close, Sasha."
"Yes! Give me details, please!"
She was clearly using him to get herself off now but he didn't mind since he was doing the same with her. Still, this part was tricky to explain. How would you describe an orgasm apart from saying that it felt good? After a few seconds of thinking, he decided to exaggerate things a bit for a better tale.
"I can feel it coming. I can feel my sperm slowly accumulating in my balls, ready to get released."
Her eyes bulged out at the description and she started to schlick at full speed, her juices splashing everywhere. He continued stroking himself a few times and added.
"It's close now, the sperm is moving up my penis and... I am coming, cumming!"
He ejaculated with force, his jet of spunk going up in the air and landing on his belly and pelvis. He thought that Sasha would rush to get his sperm like she usually did but not this time. It felt like she wanted to keep the experience as close as possible to a real solo self-satisfaction session. Instead, she continued to masturbate at high speed and reached her climax just after his own while looking intensely at him orgasming.
He released some more spurts of semen, all landing on himself, either on his hand, penis, or belly. Sasha trembled greatly on her seat, convulsing in rhythm with his jets of sperm and moaning joyfully until Benjamin was done. He thought she would stop there but that was wrong. As soon as her climax ended, she resumed her hand movement.
"Damn, you're so hot covered in your seed like that."
She even added her second hand to the dance, one focusing on her clit and the other one fucking her insides, both going at full speed. It didn't take her more than a few tens of seconds to reach another orgasm, her pussy contracting strongly and her body convulsing while she released a big moan of pleasure.
"Mhmmmm!"
She shivered for some moments before finally stopping herself and relaxing in her chair, happy to have realized her fantasy so perfectly. Once she was good again, she looked at him one more time and declared.
"Let me clean you up."
He thought she would get some tissues like she often did but she surprised him by getting on her knees in front of him and taking her tongue out to lick his semen-covered hand. Seeing his expression, she conveyed.
"Don't move, I will be done soon."
She resumed licking his hand until it was completely clean. She then shifted toward his dick, removing any trace of his spunk on it. She did the same for any part of his body that had become dirty, happily swallowing his sperm and licking him clean. Seeing her so devoted to the cause, he couldn't help putting a hand on her head and caressing her hair with affection. She grinned even more brilliantly at his gesture and continued what she was doing. Soon enough, he was completely free from any remnant of his previous act. He thanked her and they were now ready for the second part of today's session.
Sasha went to get the toy again and looked at him with a perverted expression. This expression never failed to get to Benjamin and he asked her, curious.
"How should we do this?"
