Sis gives her cousin an explosive blowjob and swallows her cum. After finding out her parents were not arriving home for a few more hours, the young sister excitedly reached into her brother's underpants. For a long time, she had wanted to try his penis and now was her moment. Taking out her brother's red hot dick, she put it in her mouth and started pleasurably massaging his testicles. Her sensual performance ends with her taking his cum on her tongue.
