"How was your date with Juliet yesterday?" Alex asked.

"It was fine." Justin said. "And it wasn't really a date, we were here the whole time." He added.

"That's not what I wanted to hear, give me details." Alex said.

"Like what details?" Justin asked.

"Did you get to cum?" Alex asked, getting closer to Justin, hand on his leg.

Justin moved away from Alex but Alex persisted and got closer.

"Answer me, Justin. Did you get to cum?" Alex asked again.

"I did." Justin said sheepishly.

"How did she do it?" Alex asked. "Did she let you out of your cage?"

"Yeah, she let me out of the cage, she wouldn't be able to make me cum if she didn't do that." Justin said.

"Oh but she would." Alex said, winking, obviously referencing what she had done to make Justin cum.

"She doesn't know about that, she doesn't know that I can cum from just cage vibrations." Justin said.

"Really, she has no idea? She has no idea about the various ways you can cum without using your cock?" Alex said.

"No, Alex, for the third time, she has no idea." Justin said.

"Maybe I should tell her, and then she'll be able to have as much fun as we did." Alex said.

"No!" Justin said.

"Why not?" Alex said.

"Because if she know she's not going to let me out as much." Justin said. "And she can't know about anything you've done to me."

"You better let me make you cum again then if you don't want me to tell her." Alex said.

Justin didn't want Alex to make him cum again, but Justin even more so didn't want Juliet to know about Alex making him cum, or Juliet to even know about how he could orgasm without being taken out of his cage, because that would probably mean even longer chastity time for him. The other problem with length was about Alex though. If Alex kept making him cum in his cage, his orgasms wouldn't be as strong as they usually are, and Juliet would probably start locking him up longer.

But it would probably be a few days before they saw each other again in a setting that Juliet could unlock Justin, so it there was no harm in letting Alex do what she wanted just this time, as long as it meant that Alex wouldn't say anything to Juliet.

"Fine." Justin said, and Alex happily dragged Justin into her room and had his pants down.

She plugged in and turned on the vibrator and pressed it against his cage. He was already hard, he was a bit mad at himself for already being hard, as hard as he could be in the cage, because he was hard because of talking to Alex. He was mad at himself for getting erect at their conversation, a conversation with his sister, and it was like his cock was anticipating and enjoying being made to cum by his own sister in his chastity cage.

It didn't feel nearly as good to have the vibrations on his cage as it did before. He wasn't as frustrated and desperate as he was two days ago when Alex made him cum the first time. They were going to be here a while.

It was humiliating, to have Alex hold and rub the round head of the vibrator against his cage and against his balls. Sometimes she moved the head of the vibrator around his cage, making the vibrations feel different on his cock.

He was leaking pre-cum now, but he didn't feel like he was going to cum quickly. The vibrator was starting to get a bit hot.

"Alex it's getting hot." Justin said.

Alex pulled it away.

"Guess we'll have to wait for it to cool down." Alex said.

She rubbed his cage, touching his cock.

"It looks so funny in the cage." She said. "And you drip so much when I play with you, I think Juliet would love this." And she continued to tease him while they waited for the vibrator to cool down, and Justin continued to leak pre-cum before Alex finally took the vibrator and pressed it against him again.

Now he was desperate to cum, with all that teasing that Alex had done to him, he was going to cum really quick and really hard.

He shot out not as much cum but it felt hard for an orgasm that was his third day in a row cumming. Alex watched him with amusement again, cumming in a chastity cage was so interesting to her.

Justin would have to try and get Alex to not make him cum as much over the next few days because he never would know when Juliet would want to hang out again and make him cum again. It would not be as long as it was before, and he was no longer desperate enough to let Alex make him cum.

But Alex, oh Alex, she wanted watch Justin cum over and over again in his cage, it was so fun to watch. If it were up to her, he'd never get out of it ever again, he'd always be cumming in his cage.
