for the basic premise it's gonna be that while you were cleaning my room, you found my hidden stash of weed, and you're gonna punish me by making me smoke it in front of you. you start to crave a hit as the smoke fills the room, so you ask your son if he could share. you take your hits, the weed starts making you horny, and you begin teasing your titties without realizing it. you continue to reprimand your son, but saying that you understand because you used to smoke. you just wish i would have been honest with you. because of your subconscious teasing, you've made your son hard. you notice the erection beginning to grow in his pants, and ask him if there's anything else he wants to be honest about. he hesitates. you tell him that it's okay, but he still won't say anything. i guess you're going to have to continue punishing him for not being forthright with you. you slowly start taking your shirt off, teasing your son. he's definitely hard now. you remove his cock from his pants. you ask him to take another hit. you take one as well, and blow the smoke on his cock as you start to put him in your mouth. you continue to suck and smoke with him, reassuring him that it's okay to be honest, that your mommy is the one person in the world you can be honest with. the fact that you're doing this to him is a sign of good faith. as you start to feel his balls tightening up, you ask your son if he can at least tell you where he wants to cum. he tells you he wants to cum on his face. finally an answer! you thank him for taking that step, knowing that it must be hard to talk being as high as he is, and reassure him that you were just messing with him this whole time. you take his cock back in your mouth. you've been sucking his cock pretty sensually up to this point, but you slowly start speeding up and getting more aggressive to the point that you're throating your son. he's so taken by seeing his mom gag on his cock that this puts him over the edge and let's you know he's about to cum. you take out his cock and jerk him off all over your face, covering your face in cum. surprised at the size of his load, you let out a soft, shocked giggle. you thank him, letting him know that if he ever wants to do this again, to just let you know, and also to let you know next time he reups, because that was some good stuff and you want some for yourself
