The toilet gurgled behind him as Sokka left the bathroom, pulling up his pants. He crossed through the bedroom, and as he passed Suki's dresser, he noticed something that hadn't been there a few days ago.
It was a black case about half the size of a shoebox, which Sokka didn't recognize at all. Usually, he didn't like going through Suki's private stuff, but she and Aang were at the pool together, so his curiosity got the better of him.
He flipped the latch and opened the case, shocked at what was sitting inside. Besides a set of handcuffs and a ball gag, there was a yellow butt plug and a box of XXL condoms, too. Sokka had never seen any of those items before, although he didn't have to think too hard about where they came from.
Beneath the handcuffs, he noticed something else, and with careful hands, lifted it out.
The collar was also yellow, Aang's favorite color, and there were three words printed in stylish lettering:
Property of Aang
Sokka had a feeling that even if his friend bought the collar, he wasn't the one who wore it. Instead it was meant to be worn by someone else willing to pose as Aang's personal plaything. Someone who really enjoyed letting him use her body and devoting herself to his pleasure, even if it was merely a kinky game.
It didn't take much to imagine Suki wearing the collar, letting Aang handcuff her to the bed and gag her and watching him stretch an XXL-sized condom over his big dick before thrusting inside her and fucking her into his new waterbed.
Or maybe since the toys and condoms were here, they did that on Sokka and Suki's own bed.
Sokka wondered how many times Aang had bound and gagged his girlfriend in same room he was in right now. They usually went back to Aang's place after their frequent dates, and Suki usually stayed overnight, but it was possible that they had sex in both apartments.
Hearing the front door open, he quickly returned the collar to how he found it and closed the box.
