We shower together but be careful with your cock
A hot day and everyone wants to use the bathroom, but this kid also wants to see things he’s not supposed to see. However, his stepsister seems to not have as many problems as him, she can set the rules of coexistence at home because they are alone. That means that if she says: “Let’s take a shower together, but be careful with your cock,” it means that he has to get as close to her as he can. And then she will want to give him a blowjob as normal. Because it’s hard and then she’ll want it inside her pussy. As always happens.
