It really enters quite effortlessly

I had already been surprised at how soft and relaxed she was, when I gently widened her sweet hole with my tongue. Now as I held the tip of my rock hard, lubed cock against her sphincter, I could feel her relaxing even more. With a low moan she pushed slightly backwards and I felt the muscle under her velvety skin embracing my glans. Millimeter after millimeter she slowly pushed my cock into her guts. „Uhhhhh. Ohhhhnnnnggg. Sloooooowwwwwwhmmmmm.” She was nearing the broadest part of my dick. „Haaaa. That. ... is” She stopped and panted. I reached out, intensified her sensation, amplified her Lust and encouraged her to talk openly. It took her a moment to adjust to my size and to catch breath. „It's so big! Alex was the biggest guy I had so far, but you... Oh my god. It feels so gooooooo” She began to push back again. „Ohhh. Ha!” When my Glans had entered her fully, I immediately felt her sphincter close around my shaft, gripping me tight. I held still. Listening to her panting. „Ha. Han. Hnggg. Phew. You're in. Oh god. It feels so good. Better than... Oh my God!” The rubbing of her clit intensified. „Ohmygod. I'm gonna... oh...” She was nearing another climax, but in her mind, I managed to hold that back for a moment and let it grow stronger while I slowly began to push myself deeper and deeper. In a single, slow yet strong movement I entered her body deeper than ever a man before. All the while she pushed slightly back to hold her position and moaned in pleasure, entering a world of bliss.

By the point I had buried my member almost balls deep in her ass, she was completely lost in the moment and I changed direction. I began to pull out slowly. She reacted with a low groaning. As I felt her sphincter at my my glans again, I started to slowly and carefully fuck her. I had no real experience with anal so I used my powers to monitor her sensations. But she was a pro, had been properly prepared and I had her under my influence amplifying lust and pleasure, suppressing pain and steering everything in the desired direction. There still was a small amount of pain under it all, but sexual bliss dominated her world completely. I could also tell there was a powerful orgasm building up in her and I wouldn't be able to hold that back for much longer. On the other hand. After her blowjob, her riding me to her first climax and her dirty talk while taking her from behind, me not being close to orgasm myself would be bordering on the miraculous. It took me a couple of minutes before I had to concentrate on myself to hold back for just a couple of more slow thrusts into her perfect ass. But that meant letting go of the influence I held over her to hold her orgasm back and when I did that, hell broke loose in her mind. Her climax washed over her body like an unstoppable **** of nature. She screamed, burying her mouth in my pillow to keep it down at least a little bit.

I noticed the energy like feeling, that accompanied my newfound abilities wandering into my groin, going even deeper condensing in my balls and my rock hard, raging boner. But it was too late to even think about what that might mean.

„Shiiiiiiit! Yeeaaaaasssss! Haaaaanggg. I'm cummmminng!” Dianes legs were shaking, in fact her whole body was. With trembling limbs she was trying to push my cock even deeper into her. „Pleeeaanngghhh!” „Han. ... Diane!” My thrusts were a helpless staccato of instinctual movements. I was already over the edge. My holding back was just a **** attempt at prolonging the orgasmic feeling seizing my mind and body. I couldn't have pulled out even if I tried, especially not with her sphincter gripping my cock so tightly below my engorged glans. Still I felt obliged to at least try and say something. „I'm gonn... Ohnggg.” „Pleeeaase. Come! Come! In! hannghh... myass!” That was all to much. I lost every bit of control. I grabbed her hips, and pulled her towards me, my cock pressing into her. I grunted while she tried to muffle her screams with my pillow. I felt my cock twitch inside her, my balls started jumping, I felt my urethra expand as I began to forcefully pump my seed into her ass. Rope after rope I released into her. Her legs finally gave way and we sank to the mattress, my cock still pumping, her legs wildly shaking.

We came to lay down one another, she on her stomach, me on her back both of us panting heavily. Her face was covered by her hair. With a sweet gesture she moved the hair from her face. Some of it got stuck in the sweat that was covering her body. „Wow. That... that was... intense, D.” „Yeah... I'm... I dunno... Thank you Diane.” „I think you need to pull out.” She said with a smile and pushed her hips slightly up. I tried to get up myself and with this movement I pulled my slowly deflating cock out of her. My shaft moved through her sphincter until my glans reached the annular muscle. I slowed down and carefully pulled out. She immediately sank back and laid down again. She looked at me, „maybe you wanna... wash up... before Leon comes back?” „Uh yeah. You're probably right.” So I stood up and went to the bathroom. When I came back, Diane was still lying on her stomach. I laid down next to her and she cuddled against me, pulling my arms around her until my chest was close to her back. Then she rolled back onto her stomach bringing us both back in the position we shared our intense orgasms. „That was really good and intense. Better than I imagined”, said Diane. „Yeah. It was... I lack words. Just thank you for that Diane.” „I could feel you cumming into me. I mean, I always feel when guys cum into me. I love that , but this was different. It felt like you really came alot.” I was slightly embarrassed then I remembered, I had encouraged her to speak very openly about that so I took a heart. „It's not always the same amount, but it felt like a lot to me too.” She rubbed her face against my arms and hands saying nothing, just smiling. „Won't you... find out... at some point I mean... It will...” She laughed. „You mean when I push it out?” „Yeah...” I could feel my cheeks redden as she laughed. Then she moved her naked body under me, signalling me to get of. I laid next to her and she changed position to lay on her back as well. One hand under her head, the other caressing her belly in a preoccupied manner. „I thought about that. I... I could feel your cum shooting out... The warmth spreading in my body... I... I think... I think I can still feel it. Spreading... this... warm feeling. It's weird. But... I dunno. ... Comforting. I never felt that before. I... I don't want to push it out.” A few seconds of silence followed. „Do you think that's weird?” „No, there is nothing to be ashamed of, remember. In fact... In fact I am glad if enjoy that feeling. Even after... you know?” „Maybe I want to do that again some time. Would that be okay? I mean with your girlfriend and all.” „Oh that's fine. We have an open relationship.” „Yeah I know. That's a good thing.” Diane was sleepy and I felt tired as well, mentally and physically, so I grabbed the blanket and pulled it over the both of us. I issued some voice commands to my computer: „Mycroft, play album: driving under the influence of jams, by electric octopus.” „Selecting album.” „Mycroft, set Volume to 30 percent.” „Volume set to 30 percent.” „Mycroft, shut down for power off in 90 minutes.” „Shut down issued in 90 Minutes.” Diane looked at me. „Show-off!” I smirked. „Are you going to stay?” „I... I'ld really love to.” „Me too”, I said kissing her neck. She sighed and snuggled her naked body against mine. Soon I noticed her breathing change and I fell asleep with the flowery scent of her long hair and the sweet smell of her sweat and lust still lingering in the air.
