My girlfriend, who is active as an underground idol, will never let me fuck her live! We've been together for a long time, so I don't mind him letting me have sex with him raw... When she was daydreaming and dreaming of having raw sex that might come true, her older sister showed off her big tits and seduced her by saying it was OK to cum inside her! Even though I like her, I couldn't resist this temptation! While I was enjoying my girlfriend's older sister's breasts, she finally found out! Still, I can't stop and cum inside my older sister!
