After a long time, I returned home to find that my big-breasted sister, who had retired from society and become a hikikomori, was still a NEET. When I entered her room to try and reform her, it was overflowing with trash and anime merchandise. My sister, playing games mindlessly without a bra on, exposed her massive breasts, making me involuntarily hard. I tried to reform her by groping her long-neglected hikikomori tits and immediately having unprotected sex, culminating in internal ejaculation. As a result of having sex for the first time in over a decade, my sister's repressed sexual desires were unleashed! I kept ejaculating inside her until she reformed!
