Seeing his sister standing in the doorway to the living room while he lay on top of her friend freaked Mike out. He stammered, "Kimberly this isn't what it looks like we uh..."
"Oh shut the fuck up Mike!" Kimberly shouted in playful anger, "I know you just fucked the shit out of my friend! How did it feel Ashley? Looks like you enjoyed it just as much as Mike."
Blushing, Ashley replied, "I'm not gonna lie Kimberly...your brother's cock feels amazing! You gotta try it!"
Mike gasped at Ashley's words and looked up at his sister, surprised when he saw the shit eating grin on her face. He thought she would be grossed out, but she obviously was considering it. He hadn't really thought of his sister sexually before but she was pretty hot. Kimberly was also 19 and her body was similar to Ashley's, tall and thin with a nice curvy body but with larger tits that formed a nice D cup and blond hair instead of light brown. He always marveled at how her eyes were the same shade of blue as his. Mike snapped out of his gaze as Kimberly replied to her friend,
"I dunno Ashley...I mean he is my brother...fantasy is one thing but acting on it is another."
Ashley blurted out, "Oh come on Kimberly! You always drone on about you how you want Mike's cock! So rather than peek in on him while he's in the shower and play with yourself later why not try the real thing?"
Mike gasped at Ashley's words, shocked that his sexy sister actually fantasied about him and spied on him.
With a gasp Kimberly replied to Ashley, "Fuck Ashley you weren't supposed to tell anyone about that...Mike...I uh..."
Cutting her off, Ashley looked into Mike's eyes and hissed, "Oh and Mike...Kimberly and I even play together sometimes...wanna come play with us..."
Mike's jaw dropped so fast he thought it was gonna fall off. His cock quickly swelling against Ashley's stomach to the thought of his hot sister and Ashley together, Mike was speechless.
