To get closer to my new stepsister, I started opening up to her about school and relationship troubles. We grew close, building what I thought was a great sibling bond... until one day, she broke up with her boyfriend. She said it was because his huge dick made sex unbearable. Shocked and upset, I asked her to comfort me, but I spiraled into despair, convinced I'd never be able to have sex. Seeing my distress, my stepsister offered to take a look. Stunned by how big my cock was—far beyond what she imagined—she suddenly gave me a blowjob. I couldn't hold back anymore and came right in front of her massive dick.
