Stiefmutters schmutziges geheimnis: zum vergnügen des stiefsohns

I spend a lazy day at home when my stepson calls me from college. He's missing parents and his girlfriend, so we catch up on everything happening. What he doesn't know is that I've been having a gassy day and I can't help but let out loud farts while we're talking. I keep farting away, chatting with him like nothing's wrong, even though I know he loves to listen to my farts and use them for his own pleasure. I'm not going to let him know that I know his secret, but I'll keep giving him what he wants, even if it's just a bunch of stinky gas.
