Having watched the whole thing, I knew he would be hard; she being who she was would want to help relieve it. I kissed her hard.
"Proud of you, little Rusty bird." I rose and reached into my shaving/med kit, pulling out a condom. "I bought a couple dozen of these... no telling where Junior or the Doctor (or little Sis, either, for that matter) has been."
Kissed her again. "All for the cause, Krista. Make sure he uses one every time." He swatted her on the fanny as she walked away, blowing her a kiss.
Turning off the monitor video feed, I left the recorder on, and left the volume up just in case while I got to work killing off all the financial work I needed to take care of so I'd be clear for the weekend.
It didn't take long before Krista came out of his room, carrying the used condom. She knotted it and put it in a baggie. Grinning, she turned to me and said, "just in case we need this for dear daughter..." and laughed.
Snuggling up to me, she bit my earlobe gently and whispered in my year, "The young doctor has no staying power. Want to see if you can do better, Cian?" She giggled and attacked me with the stuffed kitten, and I chased her to the bedroom.
