I'm your annoying step-sister and I'm about to go out with my friends. You're sitting on my bed chatting with me casually as I get ready. I say I've been super gassy all day and have to keep burping to let it out before I leave, even moaning after some burps and talking about how good they feel. After about 5 min I see you shifting around, uncomfortably trying to hide a boner. I begin teasing you in a gentle, flirty, playful way for being turned on by my burps and begin burping even more often. I continue this until it is time for me to leave. PLEASE NOTE: this video is from November 2020 so my burps aren't as big here as they are now :)
