Teresa kissed Roland, post-coitally lazy. “You know, if you fed your vampire girl, regularly, with your come, into my body and not into little bags that you throw away, I don’t think I’d have the urge to bite you. And then you could fuck me, face to face, without pushing my face away or tying me down.” 

“I like you tied down.” That was a compliment, one of the odder ones she’d ever been given, but she knew he meant it.

He bit her breast lightly. “And I think you like being tied down, too.”

“Yes, I do. But maybe not every time? You can tie me whenever you like, but it’d be nice to think you trusted me. That you don’t trust me – and I know you’re not completely wrong, given my record – but that’s still … kind of hurtful. ”

“Ok. Then get on the pill tomorrow. And the deal seems to be, at the moment, that we neither of us fuck anyone else. Except with the other’s permission, and then with a condom. All right?”

“Sir!” She said it like a soldier acknowledging an order. Teresa realised she only called Roland sir when she was asking for something, or she was happy with something he’d said. She knew he liked hearing it. In her own way, she thought, she was training him.

“So will you fuck me now? Without you wearing a stupid bag on your cock? I want just your skin and mine together, nothing between us, and your seed when you come in me. Sinking into me. Letting me absorb it. Feeding me. I mean, I’d kind of like that right now, sir.”

Roland shook his head. “I’m still not going to risk you getting pregnant, little Teresa. We’ll still have to wait.”

Teresa kissed Roland’s collarbone, still not quite healed from her bite. “Sir, I can suck your cock. I can swallow your come, taking it all down into me, and it goes through my body. I extract its energy while it’s in my stomach, and what I can’t use passes on into my alimentary canal. And out.”

“You want to suck me off? So that I come in your mouth? And that would feed you? All right.”

“No. I mean, yes, but not right now. That’s not what I want us to do. I’m just pointing out that you don’t have to think only of my cunt. You can fuck me hard, come in me and not get me pregnant. I’m amazed you haven’t taken my arse so far. You obviously like it.”

“I like your arse a lot.”

“So we’ve got the answer, sir, haven’t we? Fuck me up the arse, and I won’t feel I have to feed on your blood. And I won’t keep biting you. Your seed, my lover and my sir’s seed, that’s got to be even stronger than blood.”

Roland stared at her, as if she’d said something strange. Perhaps she had. She could see him waking up from his post-orgasmic stupor.

He said, at last, “You know, you’re right. I come in your perfect arse, and you won’t bite me. So that’s how it’ll be, the very next time.”

“No. Idiot.”

He said, “Idiot?” She glanced at his cock. It was still mostly down, but it was becoming engaged again, starting to take notice and thicken. He noticed her glance.

Teresa still looked at him as if he were a slow child. “Roland, I’m not talking about the future. I’m saying, fuck me up the arse. And come in me. I mean now, sir.” She rolled over and lifted herself onto her hands and knees. As she’d expected, the sight of her, presented, her arse up, inviting and demanding his desire, made the difference she wanted. He woke up.

“Your arse,” he said, “is perfect. And perfectly poised. And you’ve just made the weirdest argument for buttsex I’ve ever heard. But I endorse the no-biting project. Also, your arse has the sexual pull of about a thousand ships, I’d say.”

“So?” Teresa shook that arse at him.
