Jerking Off with Stepdad | THE DOCTOR'S STEPSON | Tape 10

These last few months have been quite a ride! If anyone had told me at the start of the year that I was on the cusp of entering into a whirlwind relationship with my own stepson, I’d almost certainly have thought they were joking, but here we are!

It developed very slowly. For the longest time, we were both fighting feelings that we just didn’t understand. I guess there’s always a pretty massive hurdle to jump over when you’re dealing with what most people would define as taboo, but the more we denied the way we felt, the more obsessed we became about acting on those feelings. Then I guess it just exploded…

Jonathan is such a special boy. I am so proud of the way that he’s developed. He’s kind, conscientious, a great sportsman and his grades are off the scale good. He’s everything I could have asked for in a stepson. He’s also an insanely sexy and sensual lover and I live for every second that we spend together!

To begin with, it was hard to get away from everyone else to spend time alone together, but as things developed sexually and we started to crave time together, the stepfather-stepson trips out to the log cabin in the woods became increasingly regular. It’s so nice to be able to lock a door on the outside world and just be together, as lovers, for a few days. Most people would probably look at us and think how great it is that we enjoy each other’s company so much. It always astonishes me how much you can get away with right under other people’s noses!

We were back at the cabin last weekend. Jonathan’s started doing weights. It’s sweet - ever since we’ve been together, he’s been working on his body. I think he might be a bit conscious about the slightness of his frame. He may have inherited charm, wit and devastatingly handsome looks from his old man, but I don’t think he’s gonna end up being anything like as tall as me.

Of course, that’s all part of his appeal. I love that I’m so much taller and broader. He’ll always be my stepson and I’ll always want to look after him. When I scoop him up in my arms, I want him to feel safe and protected…

Seeing him in a T-shirt and jock, covered in sweat, lying on his back, lifting dumbbells is a sight which makes me feel very very horny. We were chilling out in the sauna at the cabin. I was in my robe and for a while I just sat and watched him, feeling vaguely proud. Then, of course, the blood suddenly started pumping in my ears. I get this insuppressible rush with Jonathan where all I can think about is sex. It’s a sort of deep, powerful, carnal instinct which kinda engulfs me and makes me need to get the spunk that made him back inside his body again.

I walked over to him and gently ran my finger over the bulge in his jock while he continued to lift the weights. His technique with the dumbbells was all wrong and despite feeling horny, I had to fix that before anything else happened! Once a doctor, always a doctor, and I didn’t want my own stepson to end up damaging himself!

I decided to show him how to lift a kettlebell for maximum impact on his glutes. Yeah, yeah, I know: I’ve a vested interest in his ass being as tight and firm as possible but it suddenly struck me as I watched him squatting and lifting the weight that he has the most perfect ass. And in that jock it looked more enticing than ever…

It had been my plan to get a big old dildo inside Jonathan for some time. We’ve tried a few sex toys in the past which have always made for some pretty intense experiences, but I saw this giant toy online and instantly knew I wanted to try it out!

First off, I needed to get him relaxed. He got naked and we kissed for a while. I doubt I’ll ever grow tired of kissing my stepson. He always smells so clean and tastes so good and it’s almost certainly the most intimate thing a stepdad can do with his lad. For me it’s way more erotic than actual penetration. I dunno why that should be. I guess there’s a closeness, an at-one-ness you get when your lips are touching and your tongues are exploring each other. Jonathan, of course, was hard within seconds. Oh to have a teenaged cock again!

He carefully parted my robe and pulled my dick out of my jock. He’s turned into a fantastic little sucker. Well, he’s had a good teacher!

I took over and sucked him. That’s another one of those sensations which never ceases to be a little strange; getting your lips and mouth around your offspring’s dick. It was crazy weird to begin with - I guess for us both - but it seems pretty natural these days, if you don’t think about it too much! He lay back with his hands on his head, enjoying the sensation - talking it in his stride.

I got the dildo good and lubed up and stroked Jonathan’s dick as I slowly pushed it into his ass. It took a bit of work, but there was a moment when I felt it beginning to sink into him. His dick stiffened and he let out a low, deep moan. It was intensely erotic to see him on his back entering this sort of sexed-up trance as the rubber dildo made its way inside him, first stretching his hole and then systematically ****** his sphincter apart.

It wasn’t by any means an easy ride for him. I pushed it into him a quarter inch at a time, but every slight motion caused him to yelp, his face contorting in a compelling mixture of pain and deep pleasure, while his young, smooth body shook and shivered.

It took every inch of the young boy’s concentration to get the dildo all the way inside. I was impressed by the focus and tenancy he showed. He was desperate to take it. With the final push, his body went still, his eyes narrowed and his mouth flickered with a smile.

I let go of the dildo and worked Jonathan’s dick before playing with his nipples. I encouraged him to jerk himself while I gripped his balls hard in my hand. His eyes instantly glazed over. He was in a reverie of absolute pleasure. His beautiful dick was bulging and ready to blow. I started to jerk him. His hands were splayed on his stomach. I wondered if he was trying to feel the dildo inside him. He stuttered out the words, “that feels so good…”

As jets of semen sprayed out of his dick, I pushed the dildo further inside him. I don’t think he’d ever experienced such intensity. But that’s the nature of our relationship. We’re pushing boundaries all the time and I feel so deeply proud to be his instructor as he learns to embrace the concept of pure pleasure.
