Nadia gasped silently behind the door. Astrid stared, her breath hitching.
Mika held her hand, wrapping her fingers around the shaft and guiding her in a slow, up-and-down stroke.
He then let her go, and to Astrid's own surprise, her hand continued the motion on its own, the familiar, beloved weight of him filling her palm.
"I know just how much my big sister loves sucking her little brother's dick."
He murmured, and Astrid's face burned with shame while a fresh wave of heat soaked Nadia's core.
The intimacy of the statement, so casually delivered, was devastating.
"That's why..." He continued. "...I came all the way here. To surprise you by offering it."
Astrid stared at him, her mouth open.
Then her eyes narrowed.
"But Mika." She said, pouting. "Isn't this more of a gift for you?" She sped up her strokes, her hand moving faster along his shaft. "If I'm the one who's going to suck your dick, you're the one who's going to have all the satisfaction and pleasure."
