Check her houserules option. Toggle the morning blowjob option into yes. In the morning blowjob, you do not need to start the blowjob. Compliment her and end the session. Now you start your day one hour earlier (7am instead of 8am). If she does not do the blowjob, that's fine too. You will notice her Defiance +1. That's good too. Go to sexual options, check bondage, see if you have the proclaim punishment option. It's a safe way to get her into bondage. Get her arousal up to 9 before you choose the fuck girl option. The safest way is to use Stimulate -> caress pussy. Once her arousal is up to 9, initiate oral sex then click the deepthroat option once. It should read "Affection +1, Corruption +2" in there. Pull out, raise her arousal back to 9 again, initiate oral sex, deepthroat, repeat. You should be able to gain 3 affection and 6 corruption in that session. Do not cum in throat or face yet. I am not sure but I think it triggers anger if she does not like you enough yet or corrupted enough yet. Keep an eye out for her stamina too. Again, if her arousal goes in the negative when in the middle of sex there, abort. Go back to stimulate, see if you can get it up.
At some point, when my stats were high enough and the girl's corruption was 20+, just clicking around in the bondage room's options passively raise arousal to 8. What I usually do then is click the stimulate button to open up its options, click cancel, repeat until arousal is 8, click stimulate one more time, and click stimulate pussy to get her to 9. You can also whip her after buying a whipping cane from Devious Tools (this is also a good weapon for capturing slaves in combat). If your flagellation stat is high enough (I think 70 should do it), you can reliably get her to orgasm from whipping which raises affection +1. If your whipping/flagellation roll consistently fails, stop.
