I asked the sexy exchange student in my house to follow me to my room as I wanted to fuck him. After he pulls his cock out I see how tiny and pathetic it is, and he tells me that it's grows bigger. I don't believe him at all, he isn't going to fuck me with that little thing so I jerk him off, and it does start to grow. I then oil up my tits and tit fuck him and it grows even more. I decide to give it a shot, but I'll need to clutch my pussy hard to feel it. He cums so quickly I'm so disappointed. I start to dismount and I realise that his cock is fully swollen and enormous now and I need to ride it again as it's perfect for me. It fills me up so much now, I was wrong to judge him, I love his cock.
