stamina contest: does size matter?

"Lead a stamina contest: stroke & suck the guys on your left and right -- whoever cums first loses, and the winner's prize is to fuck you in a pose of his choice" There's only three of us left in truth or dare, and that's what my dare of choice says. The two guys left with me have to compete, which is interesting because they're two very different boys. One is kinder, quieter, a good friend, and the other is just a total jerk. However, when they take off their pants to compete, there's another much more obvious difference -- my sweet friend has a tiny dick, and the asshole's cock is HUGE. I really don't want to fuck that monster cock, so I encourage my friend to hold on so he can be the one to fuck me. I tell him size doesn't matter at all! I bet the guy with the huge cock has no stamina! Turns out that isn't exactly true, even though he's throat fucking me deep enough that he should cum, for some reason my friend cums first -- and not even while I'm touching him? But instead as he was watching the guy with the bigger cock use me? Weird! It sucks I have to try and take the big cock, but I keep jerking off my friend a little, telling him to stay hard cause I'll fuck him after to feel something nicer! Although once that big cock is inside me... WOW!! I didn't even know my body could feel like that??! He went SO deep, hard, fast, I came before he did! Well, multiple times. As he reduced me to a total size queen and melted my body and mind with his god tier cock, he held on all the way, showing off to my friend and I how much of a stamina king he is! To my friends disappointment, I realize that size DOES matter!!! But maybe my friend isn't so disappointed, cause when I collapse and that huge cock unloads a massive load of cum all over my face, my friend also cum just by watching!? Maybe big cocks are just powerful like that!
