Your cock is beautiful – 5

Things had gone back a step between us in everyday life, the relaxed chatting replaced with the former icy silence. But she still didn’t dare insult me any more. And Stella didn’t really notice any difference. My sister was great, but she could be somewhat socially dense at times, completely missing out on the clear tension between me and Mia.

That night she knocked on the door at around midnight.

“Yes?” I said.

She opened slowly and walked in, closing the door gently behind her. She was wearing a thin nightgown. It wasn’t anything too erotic, but I could tell from the thin weave that she wasn’t wearing any underwear. I doubted she would have dressed like that to share a bed with my sister.

She stood at the door, her arms straight down at her sides, staring at the floor.

“What?” I said.

“Look…” she said. “Are we going to…do something tonight, or not? I’m getting kind of anxious, if you know what I mean.”

I sighed.

“No Mia, what do you mean?”

She looked up.

“I mean…” she said, “I haven’t…cum, since the last time we…you know…”

“Well, you went your whole life without an orgasm up until two weeks ago, why the sudden hurry for another?” I asked.

She looked away. She laced her fingers in front of her, fidgeting and nervous.

“It’s…it feels different now. It’s like my body has…woken up, or something.” she said.

I didn’t say anything.

“I just…I never really got horny that much before, but now…I get wet, sometimes, when I’m alone…And you told me not to…to touch myself…” she trailed off.

I was surprised she’d remembered to obey that rule even when I wasn’t around.

“I dumped my boyfriend.” She said, “I know you don’t care, but I don’t want to be with him any more.”

She looked away again, nervously.

“And…you told me to practice, I’ve been practicing.” she said.

Told, not asked. Better.

“Practicing what?” I asked.

“Giving head. I’m getting pretty good, I think.”

“Oh, and who have you been practicing with, if not your ex?” I asked.

“No, no one else. I’ve been using…other stuff.” she said.

I really wasn’t sure about this. She obviously wanted to do something, and she was a lot more submissive than last week, but she wasn’t quite desperate enough to beg. I was pretty sure I’d have to leave it another week or two for her to get really desperate.

“Ok, slut,” I said, turning to her.

She smiled brightly. It was kind of hot to see how much she seemed to enjoy being called “slut”.

“I’ll make you a deal. If you can fit my whole cock in your mouth, I’ll do whatever you want tonight. Sounds good?”

Her eyes widened. She looked terrified.

“I…I don’t think…” she stuttered.

“If you don’t want to try then just leave.” I said.

She only took a second to decide. She pulled her night gown off in one sweep, revealing her wonderful naked body to me. She walked over to the bed and took her usual spot, kneeling beside my crotch. I didn’t move this time, just waited.

After a few seconds she realized what I wanted, and climbed up onto the bed.

She got on her knees and reached forward. She dug her fingers under my waistband, and I pushed my hips up as she pulled down my pants and underwear. I still felt a little thrill from the sense of exhibition. My dick was already getting hard from seeing her body. She took it in her hands and began slowly licking around the head.

She spent a minute or two just admiring it, slowly running her hands up and down, feeling its girth and weight in her grip, occasionally planting gentle kisses on the shaft. She took her time with this, seeming to enjoy being allowed to hold it.

She seemed to have a better idea of what she was doing, this time. She kept swirling her tongue around the head, and never stopped the rhythm she had with her fingers. Within a minute my cock was rock hard and pointing straight up. She was almost massaging my shaft firmly with both hands, rather than the frustratingly light strokes she’d been using before. She kept her teeth completely out of the way, too. It felt amazing, I could do nothing but close my eyes and enjoy it.

Then, without any sign of preparation or ceremony, she started trying to force my thick shaft into her mouth. Her tongue felt much better than last time, she seemed more aware of how to use it. As she pushed her head down farther, she began to moan loudly. This was so much better than two weeks ago. She really had been practicing.

But not quite enough, it seemed. No matter how much she tried, she could only get about 3 or 4 inches of it into her mouth before she started gagging. She kept trying, each time seeming to get just a little bit closer, but in the end she didn’t even make it half way.

After maybe 5 minutes of this wonderful sensation, she pulled it out. She was panting loudly. Her mouth was covered in her own spit, and it was drooling down on to her heaving chest. She gazed at my cock with a look of almost hatred, and then lust, as she realized she wouldn’t be able to take it all. She met my eyes, then quickly looked down in shame.

“I can’t do it.” she mumbled.

“You’re giving up?” I asked.

“Well…look at this thing!”

She was holding it by the base, and she shook it slightly.

“It’s impossible to fit it all the way!” she whined.

I reached out and rested my hand gently on her head.

“Well, until you do, you’re not going to cum again.” I said.

How’s that for incentive?

She looked desperately into my eyes.

“Come on, that’s not-“

“Are you arguing with me?” I said, cutting her off.
