I secretly cheated on my girlfriend's sister without her knowing! I gave in to temptation and lost my virginity, and then I came inside her. While she was away... I had an adult titjob and blowjob and cum in her mouth. I had my first sexual experience using a toy. "I can't be satisfied unless it's my sister." I forgot about my girlfriend and had a real creampie! She gently kissed me and inserted herself... I couldn't stop my heart beating for the first time! The more I thought this was wrong, the more I got addicted to her adult sex appeal...!
