You let Jake in. He needs help getting cleaned up

You're still naked, so you quickly throw a t-shirt on that's long enough to cover everything. Jake heard you shifting around through the door and has been waiting patiently, so you click the lock open, step back and wait. After a few seconds, Jake slips inside your dorm and closes the door behind him. He awkwardly tries not to stare at you and you do the same and it takes more than a few awkward seconds before either of you speaks.

"Umm, good morning." You start.

"Yeah. Umm..." You keep waiting for him until he finally manages to ask, "can I have the keys back please?"

You can't just tell your neighbor that in the few hours since you locked him you already lost the keys. Looking down, a bit embarrassed, you softly say "no."

"But..." he starts to plead with you. "Please, I need them back."

"You already regret it that much?" You look down again, feeling rejected.

"It's not that... it's just that after last night, I needed to shower and, well, I can't really get clean down there."

You perk back up a smidge. "Did you always unlock it to shower when you wore it before?"

"Yeah. That's usually when I would end each session when I needed to wash up."

"So in other words," you're starting to understand, "you want me to unlock you so you can go rub one out thinking about last night." He blushes harder than he already is and looks down, his eyes finding your legs. Then, looking away from your legs, he changes his stance a bit. "I can't allow that, but I don't mind helping you get clean. Clothes off!" You order him to strip then lead him into your bathroom.

You pull your shirt off in a single move, exposing everything you have to Jake. His caged cock twitches at the sight of you. Your quick inspection of it shows it's still fitting well, but obviously is starting to strain in your presence. You get the shower running and the two of you hop in.

Jake helps rub you down with your soap and you do the same, constantly shifting around to stay under the hot water. When it comes time to wash off his cock, you pull down the shower head to use it manually. You're glad you got the suite dorm room; you doubt the communal showers for the standard rooms have detachable shower heads.

You do the best you can to get soapy water under the ring and tube of the chastity cage, but it's mostly thanks to the water spraying through the holes that you can get Jake's penis clean at all. Your handling of it gets him aroused and he's fully pressed against the chastity cage. The only thing you can think to do is flip the water from hot to cold, and keep working on him. He flinches away as soon as the cold water hits him, but your firm grip on his sack keeps him under control.

Once he shrinks back down, you manage to get everything as clean as you can and turn the water back off. Before you unhand him, you give a quick kiss to the tip of the cage. You need to make sure he stays horny after all that, of course! After you both dry off, you send your neighbor back to his room to change for the day as you do the same in your room. He tries to push you to unlock him for some fun, but you brush off his attempts while leaving the future vague. You'll worry about that once you get the key back, though you wonder if you should have gotten some head from him before sending him away.

Speaking of which, your new goal for the day is to get Jake's keys back from Emily at any cost. Your sub-goals are to meet more of your freshman class and enjoy your last Saturday of the summer.
