When I caught my younger sibling wearing my favorite school uniform I was annoyed but hardly surprised! She's always sneaking into my room and raiding my closet when I'm not around. I guess that's just the burden of being the cool older sister ¯\_(ツ)_/¯ After a bit of scolding she told me that she had a big date with her boyfriend that night, and she was planning on giving him a BJ. The only problem was that she had never given anyone a blowjob, and had no idea where to start. Of course big sister had to come to the rescue as usual! I tried to explain it but I quickly realized that its the sort of thing you have to have mouth-on experience to fully grasp. I really do deserve a best big sister reward, though I do admit that I may have enjoyed giving the lesson just a little bit. Turns out she's really good at sucking huge cocks! // tags: stacy sadistic, axel star, trans, transgender, t4t, nonbinary, non-binary, nb, enbie, cosplay, sailor moon, fuku, schoolgirl, schoolgirl uniform, japanese schoolgirl, hentai, anime, sibling, sister, family, step-sister, cocksucking, blowjob, bj, big dick, big dicks, sloppy blow job, wet and messy, spit
