I currently have a partner that is in a long distance relationship with someone else. She knows about me, it's her first time in an open relationship and she is still a bit insecure about things. So I was ok with her laying down some rules, so that me and my partner could still have some fun. Unfortunately one of those rules was no penetration, whatsoever. I tried to at least push for anal, since she has no interest in it.
I have hopes that she'll come around once she realizes I'm not trying to steal her man, and just want to have some fun, and that he also has no interest in having a romantic relationship with me and just enjoys fucking me because unlike her, I like it rough, and dirty.

The first time we had sex after this rule was created already tested us, but we found a way. Blowjobs are not penetration now are they? And I like having my throat fucked. We ended up in a sixty nine position and had a really fun time.

The second time however we failed, lets just be honest but it felt so good.

We started out slow, just making out on the couch. Touching each other and exploring, He played and sucked on my nipples as I was gently playing with his cock through his boxers. Just taking our time. We got all of our clothes off, except for underwear, and I had on some very cute panties. He rolled on his back and put me on top of him. I could feel his cock on my pussy, just creating some friction that felt nice for the both of us. And of course, some fun dirty talk, How good it feels, how much better it would feel if he could get his cock inside me, fuck me, watch me fuck myself on top of him.

I took his boxer shorts off, but kept my panties on as I started rubbing his hard cock against my pussy that was soaking through my panties. I made my way down his body and started teasing him with my mouth, and jerking him off with my hands. Before I got my mouth fully on him I just told him to close his eyes and imagine that it was my pussy, then went down on him, sucking him off. He grabbed my hair and started pushing me down, making me choke on it. We both know I really enjoy it and we have an easy "If I tap you twice it means I'm running out of air" system. It also gets really sloppy and messy. Spit and precum everywhere. He was getting really into it and there is nothing better than running out of air as a cock is being forced down your throat. Then a bit unexpectedly he pulled me up and started kissing me, pushing my panties down, signaling me to get them off, so I did.

Pushing me down he started sliding his cock up and down my at this point dripping pussy but I reminded him, he can't put it in, and tried to go down on him again, just to take some tension of him. At this point, he is quiet a bit stronger than I am, he just pushed me off him and face down onto the couch, getting on top of me, holding me down with his body weight, kissing my neck. I could feel his hard cock and he started pushing it between my legs. It felt really hot and I figured if I just squeeze my legs together and let him fuck in between them, sliding on top of my pussy, that would work great.I wanted to get a hand in between so I could start playing with my clit but he got both of my wrist and held them up to telling me to keep them there. Luckily, it was just just because he wanted to do it. One hand of his went down to my clit, still pushing me down with his weight fucking in between my legs.

I was getting very loud at this point, which he appreciates a lot and lets me know. I can feel his cock every now and then almost entering me, or trying to enter me anally. And at this point I really want it. At this point he whispers the fatal words "Just the tip, just a little bit" as he pushes in, just a little bit. My morals went out the window right then and there and I am just slightly ashamed to admit it, because the fact that we were not supposed to do it got be off way too much. I could tell he was trying, really trying, until I pushed my ass up just slightly against him and just whimpered "Please."

Like a man possessed he grabbed my hips, and pushed his cock inside me with one hard push. I grabbed the blanket my hands were on top of and pushed my hips up slightly giving him a better angle as he started fucking me into the couch grunting as I was moaning how good it felt, how good his cock feels inside me and just to fuck me harder. He didn't last long, managed to kind of pull out and come on my back, mostly, collapsing next to me breathing hard, he just whispered "fuck". I meanwhile got a hand between my legs and started masturbating quickly, already way to much on edge to care, as he had a bit of an existential crisis next to me, realized what I was doing and just asked "You liked that? Like me fucking you even though you know we shouldn't, didn't you, you little slut." And pushed two fingers inside me, which made me cum so hard my legs were shaking.

Forbidden cock is just so much better.
