I feel like we are slowly building a tradition here. Luke stop by for cleaning, as thats the only way he can get shower unlocked, as I keep his keys on me all the time. While I dont think he would misbehave if I lend it to him for a while, I think it serve few purposes. First its reinforcing the hierarchy, as he always needs to ask if I am home and if can come for a shower. Second, its symbolic of his penis being no longer completely his. He cant be unlocked unsupervised. And lastly, it create natural opportunities for tease and denial sessions, as he needs to stop by every few days. Back when we were starting I once surprised him with sexy lingerie and teased him when he came out of the shower. Thats something that sticked with me. Now I am always looking forward for, at least a short, weekday teasing. Sometimes I do it in sweatpants and oversized shirt, sometimes I pull out more sexy costume like in this video. Its been just a few days since Luke last half-ruined orgasm, so I wont be playing with his unlocked dick again for some time. While we inevitably normalized the sexual nature of our arrangement, I still want to feel unobtainable. I just want to remind him, that I am not his girlfriend, but just a friendly keyholder. He cant get everything every time. To put it simply I dont want to spoil him. I want him to be horny and constantly lusting. And most importantly I want him to be horny as hell. So, next time we are hanging out somewhere in the city I will know, that under his clothes are pair of completely full balls with a locked dick only I can (and will not) unlock. Its the best kind of secret.
