When my girlfriend came over to my place wearing a revealing outfit, I instantly felt aroused. I hugged her from behind and kissed her; she shyly responded, looking incredibly cute. I gently pushed her down, caressed her entire body, and inserted myself as she moaned with pleasure. We passionately made love until she reached climax. Later, her best friend came over and we had lunch together. When my girlfriend stepped out for an errand, I was left alone with her scantily clad friend. Unable to resist my rising arousal for the second time today, I started having sex with her. When my girlfriend returned, she joined in, leading to an intense lesbian threesome orgy scene.
