My fantasy is to be masturbated by a young female doctor while she takes ECG measurements. The fantasy first came to me after I had a good looking doctor give me an ECG examination and I thought about what might happen. The fantasy goes something like this:
The doctor asks me to undress down to my underpants and to lie on my back on the couch in the normal way. She attaches the electrodes to the different parts of my body in the usual way, including two in my groin area. She is friendly and chats pleasantly as she takes the measurements, and has an attractive smile, building up rapport as she efficiently goes about her work.
Once she has the usual measurements she gives me a winning smile, and asks me if I would mind if she did some extra tests in relation to a research idea that she has. I tell her that I am all for putting forward the boundaries of knowledge and will be happy as long as it is not dangerous and if it will not hurt. She smiles back and tells me it is neither and should be pleasurable, and that it involves sexual stimulation. Am I happy with that? I tell her that with her there I am more than happy. She then explains that she wants to monitor how the heart responds to prolonged arousal and also how it responds at the time of orgasm. So, she explains she wants to stimulate me for about half an hour and then take me to orgasm. I agree.
She removes the electrodes from my ankles and without asking further slips her hands into my underpants removes them with a very easy motion, leaving me lying naked on the table with my genitals fully revealed. She reattaches the electrodes to my ankles. Her relaxed and easy attitude means that I am not embarrassed and do not get an erection straight away. She asks me what will arouse me and I suggest that if she were topless that would help and also that if my cock was sucked it would soon be up and going. She smiles back at me and slowly unbuttons her blouse mimicking a striptease show. She lets me reach up and stick my finger down her cleavage before reaching back and sexily removing her bra to reveal a beautiful pair of rounded breasts with erect nipples.
She then sits on the edge of the couch and gently takes my penis is one hand cupping my balls in the other, and then reaches down and teases my cock with her mouth quickly bringing it to a strong erection. Once it is fully aroused she leaves it and turns back to the ECG to take measurements. Over the next half hour she continues stroking and licking my penis so that it is aroused but not reaching a point of climax, stopping every few minutes to take the measurements.
After the full half hour she takes my penis in her hand and asks me if I am ready for the climax, and I tell her that I am ready when she is. She then moves the machine slightly closer so that she can stimulate me with one hand while manipulating the knobs with her other and starts masturbating me with a vengeance and with skill so that I soon feel the point of no return coming on, and let her know. She touches the knob on the machine and I send a powerful spurt of white fluid all over my chest and onto many of the electrodes. She smiles, finishes the measurements and then wipes away the mess while still holding my penis in her hand.
As a bonus she then says she would like to see how quickly she can bring back my erection and bring on another orgasm. She brings her mouth down onto my cock, starts sucking and in a very short time has it up again and as she then sucks with great vigour it is a very short time before I feel the urge again and tell her so, so that she can take it out of her mouth and finish off with her practiced hand.
I then suggest that she may like to repeat the results next week.
