"How can rubbing together with underwear count as sex?" A three-second exchange through the fabric! My overprotective older sister's excessive seed extraction and pressure caused me (the younger brother) to lose my virginity and be forced to ejaculate multiple times! Yuika Onosaka MIAB-481

[Worried Older Sister VS Virgin Younger Brother] How can mere rubbing with underwear count as sex...? My older sister's huge ass kept rubbing against mine, a massive ass-squeezing action! Under the 3-second rule, she thrust my penis deep inside! I wanted to have sex with someone I liked for the first time, but my sister, unconsciously, used her fleshy ass for piston-like movements, forcibly breaking my virginity! Reverse nighttime ass-squeezing, seed-squeezing, pounding, and thrusting made me ejaculate ten times! Just looking at her ass makes me ejaculate; her ass angle is incredibly full! Tonight, I'm completely drained again...!
