Welcome to the board.
I may be on the wrong track here, but sometimes I think it's useful to imagine a conversation with him in which you would explain your feelings. By practicing what you'd say you can make sure you don't give him too much of a shock about how you feel.
You don't describe what these little tasks are, but let me choose a "submissive behavior" that will lead you towards a more sexual relationship.
If you begin sleeping with each other, it's very common for men to become aroused first thing in the morning. So, why not make sure you're awake a few minutes earlier than you need to be. You check if he's hard and, without him asking, you give him a blow job. As soon as he comes, you head off to the shower so that he does not feel obligated to return the favor.
I'm pretty sure he'll be delighted...and after you've done this regularly for a week or two you have a perfect opportunity to tell him why you're doing it.
Choose a non-threatening time. You could be eating, or just relaxing somewhere. One key point to what you say to him. Don't ask open-ended questions where he'll have to think about the answer. Ask questions that have an obvious answer - basically yes or no. That way you can explain things to him, and by ending each thing you say with a yes/no question you don't allow him a chance to drift off the topic.
You: "Do you like it when I give you a blow job in the morning?"
Him: "Like it? You bet!"
You: "I love doing it for you...I know you're always hard at that time and I just feel like doing something to please you. I'm so glad you like it. Is it OK if I carry on doing it for you?"
Him: "Baby it's more than all right! It's great that you like it so much, because I sometimes feel guilty that you never let me return the favor."
You: "There's no need to feel guilty...I want it to be my gift to you. I know this sounds a little crazy, but it makes me feel like I'm serving you...like just for that few minutes I'm being your slave. I know it's just a fantasy I have...I hope me telling you this doesn't freak you out. Are you ready for dessert?"
OK, so you've now established that you love giving him head in the morning, and that you feel like his slave when you do this. You've made it clear that it's a harmless fantasy, and that he doesn't need to feel guilty about you doing it. Then you change the subject before he feels that he has to share spontaneous feelings with you. Try not to put a man in that position. So many stand-up comedians have the same joke.
"What's the stupidest question a woman can ever ask a man? What are you thinking about right now?"
Because the most likely answers are probably not ones you want to hear:
- Nothing (this can literally be true - men have the ability to think about "nothing", but they feel embarrassed when women catch them doing it).
- Banging your best friend / sister / etc.
- Sports stuff
- What's for dinner?
Even if he's thinking about you, it will probably be in a sexual context that he would feel embarrassed about sharing - like wondering how he can persuade you to wear a cheerleader outfit in the bedroom. So tell him what you want to tell him, don't make him think too much about his replies, and change the subject before he feels obligated to start "sharing feelings".
If it looks like he does want to talk about this more deeply, give him some time to think about what he'll say. For example, the conversation might continue something like this...
Him: "Well...I have fantasies too."
You: "Oooh...that sounds interesting! Why don't I serve the dessert and we both think about a couple of things we fantasize about. Then we can write them down and share them one at a time!"
Now he has time to get his thoughts in order. While he's thinking you can always toss in some hints. You can even "play dumb" so he doesn't feel that he's being put on the spot. Say to him:
"Gosh, I'm thinking about a ton of really naughty stuff and it's getting all muddled up in my head. Shall we see what fantasies other people have? I bet I could Google it."
Search for "top ten male fantasies" and let him check those out for ideas.
Lean over his shoulder while he's reading and toss in some comments like:
"Oh my God...I never let anyone do anal sex with me - ever!" Then kiss him on the cheek and whisper in his ear. "I'd do it for you, though...if that's what you want from me."
For one of your fantasies you tell him you're going to give him a "golden ticket". That ticket allows him to anything he wants from you - no matter how naughty or perverse. He gets to treat you like his own personal sex slave. Anal sex...you tied up...you being spanked by him...you dressing up...him watching you masturbate...you with another girl. You want to make it possible for him to live out his fantasy, and you'll do anything to make it happen because you love pleasing him so much.
I hope that helps.
Cheers,
Stanley
