The sister, frustrated with her sexual desires from having sex with her brother, starts to tempt me, her inexperienced younger sibling. Noticing my erection, she seems delighted. Stealing glances from everyone else, she grabs my cock and says, 'Want me to teach you about a woman's body?' She then guides my prematurely ejaculating cock into her pussy, moving from slow thrusts to intense piston action, not letting me go!
