At my boyfriends request, I did probably the most perverted thing of my life.[MF][Filthy][Oral]

This week I did probably the most perverted thing I’ve ever done in my life at my boyfriend’s request.

I (26) live with my sister (25), and she’d gotten back from the gym after a spin class and hopped right into the shower as she’d made plans that night and was running a little late. She was quickly in and out, and before long my boyfriend and I were alone in the apartment again.

After a little hanky panky, he asked if I wanted to play truth or dare. Seeing as that I’m not one to turn down a challenge, (especially true when I’m horny, and he’d been working me up all evening) I said yes (of course I said yes). And that’s when he laid it on me.

He’s recently become aware of the interactions between my sister and myself (see post history) and he’s, uh, intrigued, to say the least. He’s kind of obsessed with it, actually to the point of being a little bit annoying in his efforts to get us to do things together with him. But we haven’t, and it’s extremely unlikely that we will – We did that once (a story I’ve written here before) and it’s just not something that we want to repeat. We agreed long ago that what’s between us should remain to be ours and ours alone. Every single guy that’s come along and has been aware of our situation has attempted this, so it’s nothing new. But none have been as creatively perverted as my current boyfriend and this idea.

He dared me to go into her room, into her hamper, pull out the underwear she’d just been wearing during spin class, and put them on.

I looked at him in shock and disgust. Kinda went like this:

Me: “What, why? Eww, why???”

Him: “Do it or don’t.”

Me: “I’m not doing that, and you’re gross.”

Him: >starts making chicken noises<

Me: …….

Him: “I knew you wouldn’t. Chicken!”

Me: …….

Me: >walks out of the room<

And then I did it. I walked into her room, to her hamper. Peeled them off of her tights, still damp with sweat and whatever other fluids from her day at work and her hour in spin class. I gave them a quick sniff and they smelled about exactly what you’d expect like. Threw them on the ground. Took my jeans off and my thong, put my thong in my jeans pocket, and I stepped into her wet, dirty bikini briefs. I could feel a shiver run up my spine as I pulled them on because they were COLD – that’s how sweaty they were, they’d gone cold like when you pull on a wet shirt or pair of jeans.

I shook it off. He wasn’t going to scare me. I walked back out to the living room where he was lying on the couch on his phone and he heard me and looked up and then recognized the underwear I was wearing as not a pair he’d ever seen before.

I don’t think I’ve ever seen him move so fast as when he sat straight the hell up, realizing that I’d done what he dared me to after never expecting me to do it. It was amazing to see – His eyes got huge!

Him: “WHOA”

Me: “Mmm hmm. Who’s a chicken?”

Him: “I just didn’t think you would actually – ”

Me: “I know you didn’t. That’s why I did it.”

I could tell his heart was racing. He just had the same kind of look on his face as he does when I tease him in public, or whisper something super slutty into his ear or whatever. This is my favorite effect to have on men (or women, but it’s much, much easier with men lol) – to catch them so off guard that they essentially lose all control because of how turned on they are. Pure surrender. So I rode the wave he’d started, and I took it a step further.

I walked over to him on the couch, and I straddled him. I pushed him down onto his back and I started working my way up to his face, slowly. I reached my hand into her panties and I touched myself. Inch by inch I got closer and closer to his mouth, until I had my knees on his upper arms and I was hovering right above him.

If he was turned on before, now I was super fucking turned on. I could not believe what I was doing. I took my hand out of there to balance myself on all fours and I rubbed myself, complete with my sister’s sweat, juice and all, her dirty fucking underwear, and I used my pussy to rub it all over his face. I shoved his nose into my pussy. I fucked his mouth. I rubbed it all over his chin, his facial hair, his eyes, everywhere. I made sure he was completely soaked with the combination of me and my sister.

I guess it was about 10 minutes of this before I finally pulled them to the side to use his tongue to get myself off. It didn’t take long – I never do when I feel like a huge pervert.

Pretty sure I gave boyfriend the time of his life :)
