For the Sky Race Trophy (a 150 km bicicle competition held in the mountains at high altitude) the Laboratory participates with a small team of athletes. The peculiarity is that those athletes, all volunteers from the young interns from different Laboratory's unit, are using the race for a study about the heart. For the study they are all going to wear a special screen on their chest that will make some part of their external thorax "invisible" exposing the surface of their hearts. An action cam is placed on the bicicle handlebar and pointed at the heart to record in live the athlet's cardiac cycle. The aim of the study is to analize the external heart activity during strenous physical efforts at high altitude. People can watch the live too by simply following a link on the Laboratory's site for fundrising.

It seems that the most interesting live is from Nicole, with her having the majority of viewers. She's a young and good looking woman from the public relation unit but she has a quite scarce fitness level. The head of the study told her it was probably not a good idea to enroll in the experiment but she insisted and now she has become one of the most interesting subject of the whole project. After only few dozens of chilometers she's literally out of breath and her heart, clearly pulsating in the center of her chest, is about to explode being stuck at around 190 bpm for almost an entire hour now. Normally the organization would suggest her to stop but she knew the risks and this is part of the study so she is told to give her best. The coronary arteries around her crazy-beating heart are bulging, trying to bring enough nourishment to the organ under such an uncommon circumstance. On her face an expression of pain and suffering is becoming more and more evident (she probably has myocardial infarction-like symptoms). The whole team looks carefully knowning her heart is very close to its limits waiting to see what is going to happen when that line is crossed.

Hey, sorry for taking so long, but I've had a lot of complicated weeks. I think I'll be a bit more active, or at least I hope so 💕

"I like fast heartbeats I would like a video of you bare chest...holding your breath as long as you can... you have a strong heart muscle! In the last video I could see how your heart shakes both of your breasts and your entire body... if you can't exercise maybe another video like the last video you uploaded but this time showing your belly?... I mean kneeling and holding breath as long as you can with a bare torso..."

You got it! I actually got pretty dizzy here. I couldn't totally get my belly / belly button in the shot, but you do get a few quick sneak peeks...

I tormented my heart with pressure and the little bottle, and its reaction was everything I could have wanted.

I want you to watch and listen as my heart fails. Enjoy every struggling, dying beat until it can't take anymore. I want you to use my body while it happens, getting off on the increasing arrythmias and cumming as my poor tortured heart finally succumbs. (These are the things I want to write on OF but can't. 🥵)
