Orochimaru isn't a rapist. Sasuke was the only Uchiha around that he could defeat, so it's not strange he had an interest in him. And since he's one of two Uchiha left, of course his interest in him would be quite extreme.

Naruto gaiden shows the Shin Clones. It's fairly safe to say Orochimaru simply made Mitsuki as a clone. It's interesting Sasuke influenced Orochimaru enough that he realized he wanted to be a parent.
