ANGELUSNo, not at all. I just think that Angelus would have staked William if he had tried anything, or if he had cooperated if Darla tried anything. William believed him, so, even if the situation presented itself, Spike would have run away rather than put Angelus to the test. Though, now that I think of it, right after Spike killed his first Slayer, Darla might have wanted to share in the bounty, or just to put newly ensouled Angel in his place as #4 on the pecking list by that time.
As for Dru, yes, I do believe that she let herself be controlled sexually by Angelus, at least to the extent that dhe was his, any time that he wanted her.
(to Darla) Did he hurt ya?
(writhes, smiles naughtily)
Not until I asked him to.
(stands, wrapped in a sheet)
Oh, come on. Have you seen him? With the eyes and the chest and the...
(in the corner dressing, putting on a robe)
Not like him. I mean, he's not some common vampire. He's—I don't know what he is. A giant. A titan straddling good and evil, serving no master but his own considerable desires.
And spiritual. Did you know he spent 150 years in a Tibetan monastery? Which I guess explains all the desire.
He's my arch-nemesis.
Darling. It was just fornication.
Really great fornication.
(steps in for a closer look at Darla)
She's glowing, mate.
(brushing him off)
(to Angelus) Best fit you for a pair of antlers. Been made the right cuckold, you have.
(steps out from the next room wearing a lacy negligee)
Time for another pony ride?
(sees Drusilla, gasps)
Son of a bitch!
(points from Darla to Drusilla)
The both of ya?
Angelus really did not have any control over the sexuality of either woman. He couldn't even convince them to leave the Immortal's house and stop sleeping with his enemy.
