First of all, it's not happening anytime soon. Secondly, even if it happens, Dylan is first in the line to get Sophia's mouth around his cock. I prefer it happens with Sam first but L&P pushed his content back and he is not due to get any scenes in a while. TBH, it would have happened by now but Sophia's conscience(LP's disgraceful attempt at stopping things from moving on) makes a entry at the last moment to ruin everything.
