My girlfriend never lets me do it raw! When it's time to insert it, she always gives me a condom... I'm depressed and want to have more pleasurable sex! But her sister was different! She has bigger breasts than my girlfriend and a body that looks comfortable to hug, and she tempted me by saying it was OK to cum inside her! I like her, but... I lost my reason when I saw her raw pussy! I was so into sex with my sister that she finally found out! But it felt so good I couldn't stop moving my hips! Finally, I cum inside her sister right in front of her!
