This is something that just happened today. I've been feeling a bit adventurous lately, in a sexual sense, and my girlfriend has been pretty accepting and open, not to mention turned on by a majority of the things I've suggested. This is one of the kinkier things we've done. Two years ago, when we first met, I would have never been comfortable with this, but now I trust her enough to do some roleplay.
Once every couple months, we have a semi-regular discussion that usually involves us prodding each other for any kinks that we might like to try. Usually it's pretty tame, and more like a check-up. We bring up things we were into before and like to start up again, but occasionally we introduce something completely new, and almost always, it turns out to be incredible. This is how she got me into trying pegging, and also how I got her into doing dominatrix stuff.
In the most recent of these conversations that we've had, I brought up the idea of her describing going down on/fucking a stranger, and describing it to me as we had some fun of our own. She seemed accepting to the idea, but wasn't really into it, which I was perfectly fine with. I had a hard time elaborating on what exactly I meant, so I just kind of left it alone.
About a week or so after this conversation, I suddenly had an idea to talk dirty to her online. I wanted to instruct her on what I wanted her to do with herself, and she seemed willing to try it out and see what happened. As I instructed her what to do, I decided to test the waters on my suggestion from a few days ago by incorporating phrases like "you like getting fucked by that cock?" and "I'll let you use that thick pink cock". This wasn't my original intention, but it was fun to try.
It turned out to be incredibly erotic. She enjoyed it a lot, and it was even better when I went in the bedroom to finish off the job, continuing to instruct her on how to please me.
Fast forward to two days ago. She came up with her own suggestion to have me watch her use the thick pink vibrator on herself while I watch. She can tell I was really enjoying the view, and when she sees how thick and hard my cock gets as I began stroking, she knew she was turning me on. Then she catches me by surprise.
"You like watching me get fucked by another cock, don't you?"
I was startled, and if possible, even harder than I was seconds before. I didn't even know how to respond, so I pushed out a dumbfounded smile and say "It's...kind of turning me on." In reality, what she said was incredibly hot.
Neither of us lasted long after that. This was just as new to her as it was to me. I ended up jerking off onto her clit, and she thoroughly enjoyed me licking her cum-covered pussy with my tongue. Oh, did I mention that was another thing she brought up from one of the conversations I mentioned before?
The rest of the day, I kept thinking about how hot it was to hear her talk like that. If I had ever found out about her cheating, I'd be out the door in a second, but I completely love that I trust her enough to know she would never actually partake in our sexy roleplay scenario in person. The more I thought about it, the more it kept building up. Throughout the remainder of the night, yesterday, and up until the afternoon of today, I kept building up a sexual appetite to go a bit further and experiment.
As we were going about our normal business today, I casually strike up a conversation.
"So. How about I go down on you?" She isn't startled by this at all. I often ask this, as eating her out is one of my favorite things, and I suggest it nearly every day. I, however, was surprised at how casual she was in return.
"Why don't we go to the bedroom?"
The way she put it, without any questioning, made me know that she was just waiting for it to happen. She's known I've been horny and waiting to fool around since two days ago. Soon enough, we're in our bed, naked, and making out.
I grab one side of her neck and lightly grasp it, expressing how frustrated I've been, having to wait two days to finally get to fuck her. Not being too rough, though, I place my mouth on the other side of her neck and begin to suck and bite, one of her biggest turn-ons. She's writhing as I'm passionately kissing her shoulders, and I can tell she'll be nice and wet before I even touch her cunt with my tongue.
I let my free hand wander, exploring her skin, until it finally rests on her big, gorgeous breast. She has incredible breasts and, aside from me sucking on her neck, nothing gets her hotter than me showing my appreciation of them. I lightly run my thumb over her already-hard nipple, and she squirms.
God, that's fucking hot.
"Ooo...somebody liked that," I say.
She's watching me as I stare at her tits while I play with them. I smile, very coy. She loves this. Seeing me smirk, she closes her eyes and moans as her body shivers. I reach my head tongue and place it on her tit, licking all around her areola, forcing a gasp from her mouth. Hearing her gasp is one of my favorite turn-ons, as it usually means I've either done something to make her wet, or completely filled her pussy with my cock. As I continue to lick her breast, I run my fingers down her leg.
I can tell she wants my tongue on her clit, as by the time my hand reaches her pussy, her legs are wide open and she's already soaked.
I decide I've teased her enough.
I proceed downward, and take a couple last licks around her pussy before I finally slide my tongue across the slit. She gasps again.
"Ohhhh...." she forces out, half chuckling. This wasn't a moan. This wasn't a surprised squeal. She was mouthing how incredible it felt to finally get her pussy licked. She deserved the tease, making me wait that long. I give a few powerful licks and I feel her start to squirm already. Luckily, I know just how to make her cum from oral.
She starts thrusting upward slowly as I proceed to eat her out, pushing her slick puss harder onto my tongue. "Mmmmm..." she groans, starting to become vocal. "Oh, fuck..."
"How's my pussy taste?" She asks.
