supplied to the system from the outside, and the work of external forces acting on it.
Feel, Elena? “You are the system, and I am the force acting on you from the outside,” Damon whispered, rolling a hardened nipple between his fingers.
Yes.

That is, no! No, Damon! – Elena seemed to wake up from the spell, and tried to shove Salvatore senior.
True, somehow not particularly convincing.
So Damon obediently removed his hand, but still remained seated near the sofa.
What do you allow yourself? I love your brother! – reminded Elena (and herself too), nervously trying to pull up a T-shirt – her hands trembled.
And here comes the second law of thermodynamics, – said Damon, slyly grinning.
Go to you.
Elena did not have time to indicate Damon, as she was pinned down to the sofa by his weight.
The second law of thermodynamics excludes the possibility of creating a perpetual motion machine.
In short, nothing lasts forever, just like your relationship with Stefan, ”Damon smiled smugly, hanging over her – their lips almost touched.
Elena really wanted to argue, to prove that he was wrong.
Wipe the brazen smile off your face.
And she chose an extraordinary way for this — she simply pressed herself against his damned, forever grinning lips, pushing her tongue into his mouth.

Making a very correct, from the point of view of mechanics, translational motion.
“But physics is an exact science.”
Bastard
– Elena breathed out, turning her hips.
But I still remember the purpose of our lesson.
So, the third law of thermodynamics.
Damon entered her in one short jerk.
Elena screamed and wrapped her legs around the waist, increasing penetration.
Indeed, the greater the area of ??contact of the reactants, the higher the reaction rate.
Or is it already from chemistry ?! The third law is also called.
– meanwhile continued Damon, pushing her into the couch with quick, jerky pushes.
By the Nernst theorem, I know.
– Elena uttered with difficulty, clinging with fingers whitened from the tension in his shoulders.
Good girl.
And the essence of the law is.
Elena had already barely dealt with Damon’s words – blood pounded in her temples, her breathing was strayed, and all the nerve endings seemed to go berserk, sending electrical discharges through her body.
What did they say about the short circuit last semester? – The essence of the law is that the entropy of each equilibrium system tends to a finite limit, Damon whispered in her ear. K3tiealex record private show sex video. Cam sex in skype.
