The scene with Vanessa and the old dude was good but I hope he returns at some point and tells the MC a different story. We only got to listen to her version. Would be funny if the old chap tells us that Vanessa practically demanded of him to not stop plowing her even though his boner was already starting to hurt. Throw in sentence that he believes she enjoyed it even more when she realized his predicament and made it her goal to orgasm as often as possible.
This would put a twist on her version of the story because she never made this guy look like a "fool", while the real story is probably a mix of both versions.
