Jan

her stomach, me still buried in her vagina, my legs outside hers, resting on my elbows. Knowing how strong her release had been, I was content to simply hold myself steady over her, my erection still inside her warm, wet cavern. I slid myself in and out of her slowly, more to keep myself erect than in any plan to arouse or awaken her.

Several minutes later, she stirred, and turning her head to look over her shoulder at me, said 'That felt so good; I really want to find out what it feels like when it's your penis in my butt instead of your finger.'

Kissing the back of her neck, I withdrew from her, and sat up on my knees, my glistening erection swaying slightly. Jan quickly got up on her hands and knees, turning around to take me into her mouth, sucking her juices off me as I leaned to the side far enough to grab the petroleum jelly I'd brought from the bathroom. When she saw what I had in my hand, she let my penis slide free of her lips, and said 'Oh, god!.

I am so ready to try this!', arching her back in confirmation.

She quickly turned herself around so that her ass was toward me. Easing forward slightly, I slid my erection back into her vagina a little way, withdrew it slightly, and then pressed the rest of the way in. Jan lowered herself so that her shoulders were resting on the floor, tilting her ass up for easy access to me.

Loading my thumb up with some of the lube, I placed it a little above her nether opening, then slowly spread it around between her asscheeks and working it into her anus. When it had all been distributed, I took another load, and carefully worked it into her rear opening, pushing it inside and sliding my thumb in with it to both loosen her a bit, and to help make sure she was as well-lubricated in that opening as she was where I could feel her tightening around my penis.

The third blob of petroleum jelly I used to lubricate my erection as I slowly withdrew it from her, making sure to leave a surplus on the glans. When she felt me finally gone from her vagina, she raised herself up again, so that the blossom of her anus was more lined up with how I would be entering her.

Placing my hands on her asscheeks, I said 'Remember, you can stop me at any time. If it hurts, or doesn't feel comfortable, or anything else about it bothers you, tell me, and I'll stop, right then. I am not going to just ram it in, or do anything force you; it's ONLY going to happen if you relax enough to let it happen, okay?'

Looking back over her shoulder, she said 'I know, Uncle Dan. That's why I want you to do it, because I know you're not going to hurt me. But I don't think it will – I really want to do this.'

With that, I gently pulled her buns apart, revealing the winking brown eye that was my target. Directing my glans until it was touching her pucker, I paused a moment, then pressed forward a bit, giving her plenty of time to prepare. When I felt her press back against me slightly, I pushed a bit harder. I actually felt her anal ring relax, and pressed a bit harder against her. As the pressure increased against her opening, she didn't cry out or exhibit any signs of discomfort; if anything, she seemed to only get more aroused, judging from her low moans. Finally, it happened: the pressure and lubrication were enough to let my glans pop through the initial resistance of her opening, with a small squeak from her. I instantly stopped, with the ring of her anal opening tight around my penis, just behind the glans.

'Are you okay?', I asked, concerned.

'Yeah, I think so. Just give me a minute, okay?'

'Absolutely. You're sure you don't want me to stop?'

'Don't you dare! Just let me get used to it, and I'll be fine.'

Seeing that she was determined to go through with it, I released my hold on her ass, and moved my hands forward to caress and squeeze her breasts, paying special attention to her nipples. After a couple of minutes, it seemed to have the desired effects of reassuring her that I wasn't going to move before she was ready, and to help her relax by distracting her a bit (okay, a lot:-) I could feel it as she managed to get more and more relaxed; so I was ready when she finally told me 'Okay, go ahead – but slow, okay?'

'You bet.'

Taking her ass in my hands again, I spread her cheeks enough to be able to watch as I slowly, and carefully, pushed into her again. The lubricant I'd applied to both of us made it easier, and it wasn't long before I felt the ring of her anus wrapped around the base of my erect penis. At that point, I stopped again, to give her a chance to 'catch her breath', as it were, from the experience.

Again, she looked back at me, saying 'That part was a LOT easier. It feels really weird, but I like it!'

I could tell that last part was true from the way my balls were being soaked in her vaginal juices – and the way her vagina was fairly *radiating* heat.

I could also feel the different pressures as she experimented with her internal muscles: she easily found her vaginal muscles, because I could feel the change in pressure along the bottom side of my penis. Of course, control over her anus was easy, too, as evidenced by the way she would camp down on me. What seemed to take the longest for her, not surprisingly, was the location and control of the muscles leading up to her rectum. But find them she did, and got control of them quickly enough: at first, it was only an intermittent squeezing or flutter at random points along my length, but after only a couple of minutes, her efforts were much more organized and effective.

Finally, content with her progress, she said 'Okay, I'm ready, I think.

Go ahead and start making love to me – but easy.'

Not bothering to say anything – she'd gotten me that aroused from being the subject of her experiments – I carefully slid myself back out, until only the head of my erection was in her. As I did, I could hear her give out a single, continuous moan, lasting as long as my actions did – and relaxing even more, as well.

I paused again for a few seconds, then started pressing myself into her again, and getting another decidedly aroused moan as a reward. Again, I paused a few seconds before sliding back out of her. I continued like that, pausing a bit at the end of each stroke, for another couple of minutes, ever so gradually reducing the pauses, until I was finally making slow, continuous love to her most personal of openings.

She applauded my efforts with her pants and moans, and even gasps of pleasure; finally, she was able to gasp out 'Yeah, that's it! Oh, God!

It feels SO good!'

With that encouragement, I started speeding up my actions, gradually, until I was finally, fully, making love to her nether opening. I wasn't forceful about it; rather, it was a steady (if quick), gentle pistoning in and out of her, savoring the sight and feeling of her rosebud as it slid up and down my length, tighter than even her vagina had been, but pleasantly so. Pleasantly enough, in fact, that I could feel myself start down the path to my climax.

Looking down at her, I saw that she had one hand off the floor, using it to squeeze her breasts and pinch her nipples as she rocked back and forth in time with my thrusting. Leaning forward a bit, I took one hand off her ass and slid it around her, sliding through her pubic hair, until I was able to use my fingertip to stroke and circle and press her clitoris in time with my efforts. In only a few moments, she had a small orgasm, clamping her anus down on me until it was almost painful – but not enough to stop, or even slow, me as I continued to slide in and out of her. When her spasms passed, it didn't seem to have left her any less aroused; quite the opposite in fact: she would grunt and gasp out 'Oh!' each time I 'hit bottom' on my in strokes, and give a slightly disappointed moan when I withdrew.

As I started to feel the first tight, tingling sensations in the end of my erection, I started speeding up my thrusts, as well; still being careful not to hurt her, my thrusting became more forceful, as well. At some point, we seemed to pass an internal dividing line for her, and she lowered her shoulders to rest as she responded to my thrusting with an almost continuous moan, punctuated by grunts as I thrust into her.

Finally, though, it simply got to be too much for me, and I had to abandon my attentions to her clitoris; focusing instead on my own pleasure. After only a couple of minutes, I felt the approach of my own release, and slowed down to take a few long, slow strokes in and out of her to maximize it; when I felt the tensioning in my balls that told me the next thrust would be my last, I pushed into her quickly, and then tried to bury myself in her ass as the first of several jets of semen shot deep into her bowels. Whether it was the knowledge of what I was doing, or she could actually feel it, I couldn't' tell – but it was enough to trip her into her own orgasm, as well, shrieking as it hit her. Not only did she tighten around my erection, but I could feel the spasms passing through her vagina as well, along the bottom of my buried member. The sensation was so unique – and pleasant! – that the last few sprays I released into her felt as strong as the first. Panting from my exertions, I held her hips steady and jabbed into her rear entrance a few times as her climax slowly tapered off, causing her to release another small cry and several moans.

As my penis deflated, I withdrew from her, the ring of her anus tight enough to milk the last few drops from it
