They had sex that morning before she needed to leave for work. He tried to lure her in by showing her pictures of guys cocks bulging out from their pants. Most of them were not sexy. But a few...
She said she wasn't really in the mood, but she would give him a little "time". The two of them have a deal worked out where he cleans all the dirty dishes in exchange for 10 minutes of "time" each day. She gets to use the time for whatever sexual attention she feels like giving him, and if she doesn't feel like using it that day it just builds up. This morning she had 40 minutes stacked up, but there was only time for 20 before she had to leave for work.
She climbed onto the armrest of the chair he was in, straddling him so that one leg was hanging over his knees, and the other over his abdomen. Her chest was even with his face, so she pulled her shirt up and pressed his face into her breasts.
She had her hands lubed up with coconut oil and started right in jerking him, not too fast, not too slow. She knew that since he had come recently, she was going to have to give extra attention to the head of his shaft if she was going to get him to finish. After a few minutes getting his dick really primed and pumped up she told him he would have ten minutes to come, but if he didn't he was out of luck.
He asked her if he had any tokens to use in case he didn't succeed in coming. Tokens were granted to him by her as a means to control his insatiable urge to masturbate. A token meant he could pleasure himself on his own time under whatever conditions she specified. It worked great for keeping him interested and ready in case the urge hit her to fuck him. She rarely granted him tokens on her own accord, but if he asked she often let him.
She told him he could have a token either way, but he would have to edge himself three times before he came. She wanted him to get to the absolute brink of coming each time before he allowed himself to finish. She also said she wanted him to leave her a note with the details of what he masturbated to.
He agreed readily, as it was nearly impossible to disagree with her when she had both hands working his hard cock with such devious intention. She grabbed his shaft near the tip and started rubbing her palm over the absolute tip of his cock. The sensation was unbearable. He stared into her eyes, trying his best not to squirm. She smiled back at him and went all the more aggressively.
Six minutes, she said. She held his balls tightly with her left hand, pulling them downward while she stroked him in a twisting motion on the top 3 inches of his dick. He was getting close. He never knew if he finished early if she would simply keep stroking his sensitive dick to bring the time to a multiple of five. The thought of this pre coming was always very sexy, but she had done it to him enough times that he knew it was nearly unbearable when it was happening. Still, she knew it wouldn't damage him and would give him something to think about both when he was masturbating, and when he was misbehaving so she overstimulated him every now and again. She was a good lover. Fair, yes, but not afraid to use his desire to help keep him in line.
The thought of her torturing his sensitive cock was enough to bring him to the edge. He told her he was going to come and she immediately stopped jerking him. She gripped his shaft tightly below the head and gave him a few soft waps on the balls with her other hand. She had learned a while back that gently hitting him in the balls could keep an orgasm at bay, sometime for quite a long time.
