Want? Yes. Expect? No. Not in 11.
Heather only just broke up with Tommy. Something can happen, but I don't expect it. Elena only just got some proper teasing. Nothing before ep 10 really counts. Ep 12 earliest. Would be happy to be wrong about that one.
Sally and Bianca are much more likely based on the previews. Seriously disappointed if there's nothing with Sally. Bianca however is likelier to have a moment that won't cross a line. Build up for that cheating. MC doesn't know about her relationship problems on Others. He only knows if Jill's path is open in season 2 and that blocks the Others path. You can choose another main girl over Jill, but the result is the same. Bianca is for cheating.
Anal with J&M? Actually I'd expect just one of them and it would be more satisfying if Maya were the first. It would defy the expectation.
