Stiefbruder liebt meine furzen

I don't feel good so I am under the blanket in bed.I have bad gas and try to relieve myself. My step-brother sneaks in my room.When I see him he tells me that he wanted to see how I am.I apologies for the farts he had to listen while he was standing there, but I see that he likes to see me farting.I continue to let farts out while I tease him.I see his dick getting hard in his pants.I tell him to take it out and to stroke while I fart.We are home alone and I always wanted to watch him doing this.I want to see him cum for my nasty long farts.
