Sister Mocks Your Cock and Pity Fucks You

You finally get the confidence to ask your bratty sister if she can set you up with one of her friends. Your sister considers this for a moment but says that she needs to see what you are packing if she is going to recommend it to one of her friends and ask you to drop your pants. You do, and when you reveal your tiny cock she can't help but laugh. She mocks your little cock and states that maybe you are a "grower" and not a "show-er" so instructs you to get it hard. It is still very disappointing and she tells you that you will never get a woman with that thing. Feeling bad though, she makes you a deal. She's wan a car for a while and in exchange for your vehicle she will let you fuck her. You just can't tell ANYONE about this. **This is a POV roleplay and there no visible penetration**
