I think what
Alley_Cat was referring to was the scene where Patricia goads & coaxes Sophia to join her in her plan to tease the hobos in the park. Both sisters exercise provocatively in front of the layabout crew & Patricia lightly smacks Sophia's backside as part of this hobo tormenting set up.
I'm not sure that any of what you describe means that there are going to be sex acts with many people, including fellatio, hj, or anything else. It would be totally "against the run of play" to use a football(soccer) analogy. I feel it's more likely that there will be a steady advancement in sexual activity with a select group of people, probably leading to actual sex, which would keep the story shorter & be more in keeping with Sophia's character.
Speaking purely personally, I wouldn't want Sophia exhibiting yet another trait of becoming just another porn game stereotype. There's more than enough of them out there already. I've just stopped playing AEA for the second & final time because the amount, nature & locations of sexual activity was becoming totally unbelievable. I could be thought of as old & somewhat jaded & perhaps I am but that type of porn is something I no longer find entertaining. If I ever want it again I'd just watch real porn. AWAM was meant to be different & it still is in some respects. I hope that it doesn't become just another fuckfest, albeit one that took far too many years to arrive at such a point.
