Today, I didn’t reaaaally follow the prompt. But Reyes is chilling on the Tempest – does that count?

In this one-shot, Reyes and SAM have a heart-to-heart. This is the first thing I’ve written from first-person perspective. Please let me know what you think!! ❤

It starts with vasodilation.

Increased blood flow to Ryder’s lips and cheeks turns them pink. The tissues of her genitals swell and become moist. Her pupils dilate. Oxytocin and dopamine flood her brain when he kisses her. She gasps when he bites her shoulder, but her nervous system floods with endorphins and dopamine; she finds his bites pleasurable, not painful. Her nipples harden and her breasts swell at the touch of his hands and tongue. When intercourse commences, dopamine activity increases further, and there is heightened neural activity in her basal ganglia. Her respiratory rate and heart rate increase. He quickens the rhythm of his copulatory movements, and her genital muscles begin to contract and spasm as she cries out. A burst of neurotransmitters and hormones, muscle contractions, and widespread neural activity overtake her body. Her physiological signs are very clear: she is euphoric, all bodily signals indicating pleasure and reward.

Through Ryder, I observe, and I learn, and I feel what it is to be euphoric.

***************

Ryder’s reactions to Mr. Vidal have always been different than her reactions to the rest of the crew. When we first met Mr. Vidal, I initially analyzed him as a threat. The Pathfinder had experienced a spike in adrenaline and cortisol, and her pupils had dilated, so it was my impression that she was experiencing a fight-or-flight response. However, there was a surge of dopamine in her brain at the moment that he spoke, indicative of reward. These signals were contradictory, so I did not act. Further information was required.
