My sister is cheeky. She's beautiful and at the top of the social hierarchy, so she always looks down on me... "If you can avoid repeating the year, I'll do whatever you say! Stupid brother lol" Damn it! I'm going to make her regret ever looking down on me! I managed to get promoted, and I made my sister my home massage girl! I dressed her in a lewd uniform, a micro bikini, or her favorite costume and gave her a risky oil massage! I showed her my hard dick and of course we negotiated for sex! My sister was reluctant, and we fought for 1cm through the fabric! "Oh... it's big!?" I gradually started to get lovey-dovey, and the positions were reversed! I inserted it deep into her slender, tight pussy, made her understand, and had sex with her! I let her play a slut and do whatever I wanted to her, making her squirt! I ejaculated over and over again because my sister was so cute that she completely fell and twitched!
