When I returned to my parents' house after a long time, my shut-in big-assed sister was still a NEET. She doesn't even have a part-time job and is a parasite on our parents, so I peeked into her room to see if it was overflowing with trash and anime merchandise. She didn't listen to what I said and was obsessed with games with her cheeky attitude, so I gave her a "tickling punishment"! My sister has been ticklish since she was a child, but she couldn't take it anymore and wriggled and wet herself in no time! She showed me her honest side, so I lectured her with my piston-like movements in her squirting pussy and tickled her until she was ready to return to society, reforming her with creampies!
