Proper cock inside your wife

You're wearing a satin robe and nightie that your husband bought for your birthday. "Thanks so much. I really love it!" Running your hands over your body, you say how nice and sexy it feels. "I have a little surprise for you. I found this hot guy and I'd like to put on a little show for you. You want me to enjoy myself on my birthday, don't you? You just sit down on the bed and relax." You walk out of the room and come back in a moment later, leading a guy by the hand and you're smiling excitedly. "Oh, don't mind him, he's just going to watch". You start kissing and the guy has his hands all over you. He starts stripping off. You take your robe off and let it fall to the floor. "How do you like my sexy little nightie?" The guy says he really likes it and keeps kissing you and rubbing you up and down. You take his trousers down and smile "Oh, wow, you're so much bigger than my husband." You take the robe and pe it over his cock and start gently rubbing it.
