I think so too. He could have added an animation of Sophia pulling her skirt up, kneeling down, walking into the classroom with the camera showing off her curves in a sexy way or whatever. But no, he's chosen to create only animations of characters barely anyone cares about to test the waters.
This is also the wording L&P had been using whenever he described the process of creating these animations after his patrons started expressing their frustration about the delays several times. That's not how you talk about this when there's a professional creating 'em for you. Atleast in my opinion.
It would have made some sense to have a variety of animations, not just sex. I really don't want to complain about sex considering how little this game has, but from a standpoint of project management and developing skills, it would have been cool to see a bit more variety. Probably the most erotic part of the update was Sophia hiking up her skirt. A video related to that part of the update would have been cool.
However, I have absolutely zero problem with him using Jen and Andre. To me that makes total sense to start with third tier characters, in fact I think it's a good strategy to build anticipation for the future.
But as always the problem is that the "future" is dictated by his development cycle, and it's measured in years. If we knew that something sexy with Ellie or Patricia was coming soon I think there'd be a lot more leeway granted to L&P. But this sex scene is likely to be the only animated sex scene for a year or two (I'm assuming a sex scene with Liam will happen at some point, I'm not even considering any other lover). So not only is the wait going to be extremely long, but these animations further delayed those future sex scenes from happening. It's a really bad cycle to get in, and it leaves little room to give L&P the benefit of the doubt.
