sisters bf 's bulge

Youre my sisters bf and i think i catch you taking pics of me changing with your new camera. i confront you about it wearing only a tank top and panties. i ask why you always have a bulge always in any pants and you ask if i wanna see it. i say no and laugh but im curious so i say sure why not! you pull it out and im amazed at how big you are omg i need to stroke it. i stroke you and admit ive been obsessed with your cock ever since last summer when you forgot your bathing suit so i made you wear a speedo, god my bf was pissed! i keep dirty talking and stroking you until omg its not what it looks like my bf comes home and catches us. no cumshot.
