I'm your big step-sis, I take care of you and have almost a maternal relationship with you. We are very close. I love you and only want good things for you. I catch you masturbating and explain to you that what you are doing is normal. I mention that your penis is quite small, and I feel bad for you because I can tell you can't talk a girl into having sex with you with such a small penis. You're a virgin, and totally oblivious to everything sex related. I ask if you know what the white stuff is that comes out, and tell you it's called sperm and it's normally for impregnation, but it feels ...

I'm your big step-sis, I take care of you and have almost a maternal relationship with you. We are very close. I love you and only want good things for you. I catch you masturbating and explain to you that what you are doing is normal. I mention that your penis is quite small, and I feel bad for you because I can tell you can't talk a girl into having sex with you with such a small penis. You're a virgin, and totally oblivious to everything sex related. I ask if you know what the white stuff is that comes out, and tell you it's called sperm and it's normally for impregnation, but it feels good to a guy when it comes out. I take pity on you and tell you that I can take care of your urges and can make you squirt the white stuff when you need to. I show you my body, knowing you have never seen a girl's body up close before. Then I lovingly sit down on your dick, and you immediately explode in my pussy. I am a mess inside. I mention that your sperm is everywhere inside me. I am surprised that you came so fast, but I understand, because you are a virgin. I tell you that you can come to my room when you are hard, and I will make you feel good and make you squirt out that white stuff so that your penis will feel better. I explain that you probably won't find a girl who will want to let you inside her because of your small penis, and because you cum too fast. But I am sweet and tell you it's okay and tell you I will sit on your penis and make you cum again, even though you are small and cum right away. Near the end, I laugh and tell you that no, you didn't make me feel good, you're too small and much too quick, it did nothing for me, but, this is for you and your needs, so it's okay. You can squirt the white stuff inside me anytime, and I promise it will make you feel better. Just make sure to keep this our little secret.
