this game is amazing , the exact opposite of big brother , but it's like jumping from an extreme to another , in this game you get pussy way to easily
We've only actually had sex with two (or three, depending on your point of view) characters, none of whom are even family, and to have sex with the twins you've got to betray the family - I played both storylines, but I'm only going to revisit the twins if we get more storyline about the betrayal.. I doubt we'll ever actually see them again. My "going ahead" save is going to be the one where I lied to the twins.
As to the rest of the girls: Mom wants it, but got cockblocked at the last second, Sara probably wants it but not yet (she's young and understandably nervous), and Caroline is conflicted but apparently heading our way. The sex with Celia is quasi-nonconsensual, as she's being blackmailed (despite her actually enjoying herself), and it wasn't vaginal. Our three classmates are just eye candy at this point - only one of them seems interested in us, and the other two are still enjoying our humiliation at the hands of Celia. I expect that Celia is going to come around to liking the MC (or at least enjoying having him around for a boy-toy on the downlow) before we get sex from Sara or one of the classmates.
There's a reasonable amount of sex in the bonus images, but those are "non-canon" - for example, we've not even gone to Auntie's place to clean the pool yet (much less seen her naked) and she's got two hardcore images in the bonus stuff.
