Both Steven and Matt are very well hung. Steven is much much skinnier than Matt and that may enhance the comparative size of his penis against his body. His extremely thin body adds to the impression that he is younger than he really is.
Definitely bigger than Woods, who's not shabby by any means. I think Titch Jones is a bit larger than Prior, but it's very close, along with Matt Hughes......all incredibly blessed and all a challenge for any eager bottom.
