I was standing there in my gaping nurse’s tunic, a white bra, a nurse’s cap and white stockings and suspenders. I still had cum slowly oozing out of my cunt and I had him lying face down in a traditional theatre gown, his ass framed by the opening at the back.
He knew his ass was about to be invaded by an inflatable butt plug. I parted his cheeks and opened his pucker with one hand, first spitting and then drooling onto his pucker to provide a little lubrication. I used the butt plug to spread around the spit and then smoothly but purposefully inserted the deflated butt plug through his pucker.
Then I started inflating it. He has a greedy ass, so I knew he’d take a fair size, and I kept pumping, counting the squeezes of the bulb. When he started saying how full he felt, I paused to allow his ass a chance to relax to the invasion, and I stood by his face again to allow him to look at and smell my cummy cunt whilst stroking his hair and saying soothing and encouraging words. After a few minutes, I pressed on with inflating it, only stopping once he was almost sobbing because of how large it was. I wrote down the number of bulb squeezes, and then I helped him to turn over to use his weight to keep the inflated butt plug firmly in place.
He was clearly uncomfortable, which was my plan, and I left him there with the massive invasion in his ass for nearly a couple of hours. I knew the large invasion would make it difficult for his cock to get hard again, but that was my challenge. When I returned, I took the measurements of his flaccid cock that I missed before, and then I started masturbating his cock in the same way as before, and as I expected his cock wasn’t really playing ball.
Deciding that he needed visual and nasal stimuli, I gracefully climbed onto the bed and knelt in a face-sitting type position, facing down his body with my cummy cunt hovering over his face (but out of reach of his tongue).
I knew my cunt was having an effect, as his cock was starting to stir again. I bent forward over his body, my mostly covered tits pressing into his chest, and lined my mouth up with his cock. Just before I started sucking on his cock, I felt some cum start to drip out of my cunt, and I glanced back to check it landed on his face.
All that stimulation worked, and his cock once again started to get hard. After I felt I had tantalised him enough, I lowered my cunt to his face and allowed him to start licking the cum off and out of me. That did it, and his cock once again got very hard, twitched, and this time, I took the load of cum in my mouth.
I desperately needed to cum, but that really wasn’t on scenario at this point. So, I reluctantly climbed off him, and standing next to his bed, I spat and dribbled the cum out of my mouth into his open mouth (without our lips touching). Until that session, I’d never found spitting or dribbling cum to be sexy, but in the heat of the moment, it was incredibly arousing.
When I had spat as much of his cum into his mouth as I could, I told him to swallow, and I did the same.
I was still desperate to cum, so having briefly left the room, I returned with Adam, his big dildo mounted in my strap-on harness. His eyes widened on seeing it. He knows what happens now: I always expose my clit whilst putting on the strap-on, and as I drive in and out, the flat end of the dildo rubs on my clit and makes me cum repeatedly. It is always a massive challenge for me to keep a consistent rhythm to build to his orgasm; it doesn’t feel right just to use his asshole to hold a dildo whilst I cum over and over.
Normally I warm him up with smaller dildos first, but I figured he was warmed up enough by the inflatable butt plug. I started sensually lubing up the dildo, making sure to stroke up and down the full length of the dildo with my hands.
I told him that this test I was about his ability to cum by anal stimulation alone, and I told him to turn over in preparation for the test. Adam was quite a challenge for him at this time (although he has moved on to larger ones now), and in the preceding weeks, I had only just built up to getting Adam all the way in on a vigorous motion.
I released the air from the inflatable butt plug, and in one motion pulled it clear of his ass. His asshole gaped for a few seconds, as it had been held wide open for nearly a couple of hours, and as it started to slowly close up, I clambered onto the bed and inserted the tip of the dildo in through the gaping asshole.
I firmly pushed the dildo in as deep as it would go, and he reared up with a little yelp as I drove in.
I leant forward and gave him a mirror, so that he could look back and see me riding him. He hadn’t seen me undo the top half of the tunic, so my white bra covered tits and free-to-view nipples were on show.
I focussed on his asshole and started to build up my rhythm. It didn’t take many strokes before I felt my first orgasm starting to build. I was determined to keep quieter than normal in these circumstances, but some noise did escape my lips as I came the first time. As usual, I tried to not break rhythm, despite a shuddering orgasm, and then I carried on with a slightly higher tempo. Wave after wave passed over me, and all the time, his asshole just accepted Adam’s full length every time.
Eventually, my clit was starting to feel a little sensitive and a little tender and my rolling orgasms came to an end, allowing me to focus solely on his asshole and making him cum. With me making sure I was almost making the dildo pop out of his asshole on every stroke and driving it in as hard as I could manage on every stroke, he got louder and that made me even more resolute to complete the job.
I was in a race against time before my body gave out, but each moan of his was a little louder until eventually his body tensed and then released as he screamed out. I had a final few big slams into his asshole, and then lay down so my tits rested on his back, cuddling down to him.
Once I got my strength back, I got up, extracted the dildo from his asshole and climbed off. Then I rolled him over and looked at the mess I had made. I bent over and licked his cum off his body and the sheets, and then leant over him and again spat cum into his mouth.
With my tits still out, I declared his examination over, and that he may be called back for some more tests at a later point, and I left him to it.
I was very happy how that session had played out and I had more good ideas for the next session, but had to wash the uniform first, as it appeared to have cum on it. Not sure how that happened!
