First you should know that both of us are pretty nerdy, she's the hyperactive type whereas I'm more cynical in demeanor. Of course, I was watching the WWE PPV, and while it was dull, she was being extremely playful, and doing her little overly cute mannerisms.
My girlfriend likes to be excessively playful to get my attention. Most of the time it works, but even though Randy Orton and Jinder Mahal weren't necessarily warranting my attention, I'm at least enough of a wrestling fan to keep from deterring away. However, she had her ways of persuasion. She liked to do this pose with one hand on her hip that showcases her booty. She knew she would get a response from me for that, and for good reason. She is well endowed back there. I would say she's like an African-American JJ Plush in figure. Add to that she was wearing a nightgown that barely went below her stomach and it drove me crazy.
"If you keep playing like this, I'm tying you to the bed."
This was usual joke fare, for us, from me threatening to hogtie her to her threatening to duct tape me, but it never went anywhere. We would just shrug it off for the most part, usually she would just say "you're a mess" or something to that effect. However, this response while slightly different completely changed things.
"I'd like to see you try!"
With those words, she practically sealed her fate and gave me the go-ahead. This was a dare! Surely she didn't think that I was going to let this opportunity slip. I rose up and grabbed her hands, dragging her towards the bed. I have to observe that she wasn't putting up as much of a fight as she usually does when we horseplay. I put her on the bed and sat on her back, moving her arms behind her back.
"No fair!!"
I looked for the closest thing I could find to tie her hands; the sash of a bathrobe. With her struggling, I couldn't get her hands together! As I struggled, she soon broke free and started moving to the next room. Heck no. We've been dating over 3 years, I wasn't about to let this opportunity slip away. I looked on the dresser at her Ace bandage. Perfect. I grabbed the bandage and started towards her. When she saw her bandage, she said "What are you up to..." with a wry grin. I grabbed her and brought her back to the bed.
I had a game plan this time. I used the robe sash on her feet first. Afterwards, I used the ace bandage to tie her hands tight together in the front. Finally, I tied the wrists to her feet. I had my gf in a simple front hogtie, the hell with the Championship match! As she struggled and stuck her tongue out at me and started talking trash, I put my hand over her mouth. To say hearing her muffled attempts at speech was music to my ears! Not only that, she sounded like she was enjoying it! I tickled her for a little over a minute. She's extremely ticklish(and so am I), so tickle fights are the norm for us. What wasn't the norm was for her to be that helpless and my hand covering her mouth to block her laughter.
After this I smacked her bottom a couple of times, then had a small back and forth with her.
"You've been dying to do this, I see! You seem to be liking this an awful lot"
Hells yes I was, but her taunting was enough.
"You know boo, I think you need to be quiet for a little while."
She looked at me wide-eyed with a intrigued grin as I brought out a roll of duct tape.
"Really! You're going..."
I covered her mouth briefly and put a strip of duct tape across her mouth. Her muffled gag talk was music to my ears, as I put a strip above and under the
first one for good effect. I sat on the bed and admired the beautiful sight before me. My gf bound and gagged on the bed beside me. I playfully tapped her on the bum a couple of times and took pleasure in her muffled talk. I planted a firm kiss on her gagged lips. Always wanted to do that.
"Now I have to finish watching this event boo, but Ill be back in a few minutes. Stay comfy..."
"Mmmph ghhh pihhh uhhh Tiff!!"
Crap! It's a good thing I went easy on her not wanting to scare her her first time so I made out what she said. We have a coworker we pick up from work time to time, thankfully our job is not even 5 minutes away.
"What time?"
"Tmmmn!!"
10 o-freaking clock. I look at the clock. 9:46. DRAT.
"UMMM-HMMM"
(She's such a smartass sometimes)
"That's why the tape comes off last."
"Hmmph!"
True to my word I undo the legs first. As I do that, she's finally able to bring her hands up to undo her gag. Together we take off her hand restraints.
"Meanie!"
"You asked for it!"
"I ought to tie YOU up to see how YOU like it!"
"Uh-huh, suuuuuurreee...(not hiding the fact that I would actually like it, a whole lot

"I could get you, I might get you in your sleep!"
"Yeah, look forward to it." (Dry grin because it's both funny and I know I would seriously look forward to waking up heavily bound and gagged by a vengeful gf)
Yeah, this was my first time tying up a sexy woman, especially my gf. Hopefully she carries on with her threat and I can write about my first time being tied up by one. That should last longer because if it happens I plan to behave in a manner for her to keep me like that for a while. Or I'm fine with tying her up again, maybe I can do a legit behind-the-back hogtie. Use her as a footrest for a half-hour while I practice Tekken. Anyway that was my stretched out story(the entire ordeal was 20 minutes at most), thanks for listening!
