Recently, it seems my sister has a boyfriend… To get praised by her boyfriend, I (her brother) was used as a practice dummy for blowjobs. 'We're siblings, but if it's just blowjobs, that's fine, right!' she said, and my sister started practicing blowjobs. 'Come on, big brother! One more time!!!' While I was ejaculating, she continued to suck without rest, making me shoot repeatedly with her mouth full of semen. My dick was twisted and turned until it went numb. Unexpectedly, my sister was serious about it…
