My husband Steve had been reading an article about prostate massage, and he had become somewhat fixated by the idea of having it done. He kept mentioning the mind blowing sensations he'd heard about, and it was like he didn't dare ask me to do it for him. So one day I took the bull by the horns, so to speak.

We were in bed one Sunday morning having a leisurely lie in, just talking and cuddling, and I held him in my arms and gave him a gentle kiss.

‘Baby,' I whispered, ‘would you like me to try to find your special place?'

I felt him squirm against me. I felt his cock twitching and stretching in anticipation. ‘Ooh, I think so, yes please...' he replied, a hint of hesitation in his voice. I kissed him softly on the mouth and he returned my kiss, sucking my bottom lip into his mouth, his breathing quickening as his excitement built.

I wasn't quite sure where to find his prostate. I regularly kissed and licked his bottom, he loved that, but I only ever slipped my finger inside him a little way, frightened of hurting him. When I did that to him he pushed back against me, obviously wanting me to reach deeper inside his rectum, but I always withdrew my finger, I guess I'm nervous in case I cause him discomfort.

Anyway, that Sunday morning I'd promised him something and now there was no going back.

‘How do you want me?' he asked, looking at me with his big puppy eyes.

‘I don't know Steve,' I said innocently, ‘just make yourself comfortable and let's see how it goes.'

He lay on his side, his knees drawn up to his chest. That's the way he likes to lie while I rim his anus, it opens him up and he's comfortable in the foetal position. I went down to his bottom and gave him some gentle licks, probing his little wrinkle with my tongue, moistening him and trying to get him to relax. It took a while, but eventually, I felt his anus relax to my tongue and I was able to slip it up him a tiny bit. This drives him wild, he was moaning and holding his cock which by now was hard as a rock.

I didn't know what to use for lubrication. I had some hand lotion nearby but didn't want to use that because I thought it might sting him. So I reached between my legs and used nature's own... my pussy juice. Playing with his bottom always excites me, and there was plenty of lube right there on tap.

I simply scooped it out and spread it around his hole. His eyes were closed and he was sighing and moaning. Almost panting in anticipation. I touched his anus with the pad of my index finger and it contracted, tightening up at the idea of an invasion. I gently circled his sphincter, stroking his ass cheeks with my other hand, trying to get him to relax.

‘Go on,' he said, ‘put your finger inside me Sara.' I needed encouraging, I was more nervous than he was.

‘Relax then,' I said, ‘let's see where this magic spot is...' and with that my finger popped into his anus. I held it there to let his inner sphincter relax. I know from my own experience that to force my finger inside him would hurt him. After a minute, my finger slid easily into him, and I slowly stroked the silky walls of his rectum. He was pushing back against me, breathing hard.

‘Oh Sara, that feels lovely.' he moaned. This was making me really hot. I looked at his cock and it was rigid, his balls tight and full of cum.

Inside him felt tight and hot, and my finger was so deep that I felt the tip of his morning bowel movement, I wondered why I wasn't grossed out by that but then it's part of my darling husband, why should it?

‘Mmmmm...' he moaned, and I wondered if I'd hit the spot. ‘Turn your finger over, feel at the front', he said.

With that, he rolled onto his hands and knees. His ass seemed to suck my finger in, and it was easy then to press down gently and feel towards the front of his rectum. Just then, I felt a small swelling about the size of a walnut. I guessed that's where I'd been aiming, so I gently stroked it with the pad of my finger.

‘Ohhhh!' he groaned, his head went back and he spread his legs wide and reached for his penis. I looked between his legs and his penis was leaking sticky pre-cum like I've never seen. I carried on massaging him, giving him little nibbles on his bottom and cupping his balls with my left hand. He was writhing around, pushing right back and I looked at his face, his eyes were almost rolling back in his head.

He seemed then to lose control. I'd maintained a steady stroking action of the little bump inside his, but now he was gripping his cock and pumping it urgently. His head was down on the bed, his mouth open and saliva drizzling onto the sheet, his moaning turning to a low growl, his cock swollen and purple.

‘Ohh yeah, yeah, uhh uhh uhhhh..' he growled, and jets of his cum spewed onto the bed, long ropes of cum, I thought it would never stop. He was shuddering, milking the last drops out of his cock, squeezing out his foreskin. I left my finger where it was, buried in his rectum, afraid to move, not really knowing what to do.

He collapsed onto his tummy, exhausted. I stroked his back and bottom, there were beads of sweat on his back. I slowly worked my finger around in his bottom, disturbing his motion which was still buried inside him, but not quite as deeply.

‘Careful,' he warned, ‘you're making me want to go to the toilet'. He excited me saying that, I thought about going a step further, coaxing him to relieve himself in front of me, but I thought I'd save that for another time...

‘How was it, baby?' I said, and slipped my finger slowly out of him.

‘Beautiful', he said, ‘I thought I was never going to stop cumming'.

I snuggled against him, stroking his softening cock. My pussy was dripping, I was desperate for him to touch me.

‘Oh-oh, think I need the bathroom' he said, and sprang out of bed clutching his bottom. I laughed. All that fingering had stimulated his bowels and as he trotted out of the room to go and empty himself, my fingers crept down between my legs, and I indulged in my secret fantasy ­ watching him on the toilet. Ahh well, another time, perhaps.
