GDHH-164 "No way, sis! If you move any more, I'll slip it in!" Wet and squishy — thrust?! Unexpected live insertion! "Sis is inserting it!" "I'm not inserting it..."

Tired of my kind sister coming to my room over and over again because she's worried about me not going to school, I said, "If you let me do it, I'll go to school!" To which my sister replied, "I'm fine with dry humping." What an unexpected turn of events! The pleasure from dry humping with my sister's soft thighs was like heaven! It felt so good that I came right away. Did my sister get aroused too? My sister, who was vigorously dry humping me, ignored me when I said, "If you move, it'll go in!". She completely ignored it even when it actually went in! It's just dry humping! she insisted, and inserted it multiple times! I ended up ejaculating inside her!
