My girlfriend never lets me do it raw! She gave me a condom before penetration, and I still can't do it raw... I was starving for the raw sensation, daydreaming about when she'll say "it's okay to do it raw," but her sister showed off her big tits and tempted me by saying it was OK to cum inside her! I like her, but I can't miss this temptation and opportunity! I was rubbing her soft tits and fucking her sister, and she finally found out! But it felt so good that I came inside her vagina!
