Beth took her time settling her little one to sleep. So sweet! Such a good boy. She spent a number of extra minutes just watching him. So precious. And then she quietly closed the door and stepped lightly back downstairs.

Yup, her husband Tom was having his cock sucked by her sister Avis—a kind of vertical sixty-nine, with Avis balancing on the arm of Tom’s favorite leather chair. The blowjob appeared to be pretty far along. Tom’s face was buried in Avi’s pussy. Beth wasn’t sure whether the slurpy sounds she heard were from her sister’s cunt or her husband’s cock. Maybe both.

Oh yes, he was coming now, a succession of cock-jolts filling Avi’s mouth with his hot cream. Beth knew his eyes were squeezed tight--a rictus of extreme pleasure. So sweet! So precious! Such a good boy.

Beth entered the room. “Hey,” she said softly. Avis released Tom’s cock. A strand of seep dangled down. Tom eyed her groggily, his face full of Avi’s gush. Avis turned, her eyes aglitter with lewdness.

“Did you save any for me?” Beth asked.

Avis half-smiled and opened her mouth. Bubbles of cum-froth topped the pool of rich cream. Beth hurried to the chair.
