Sam only noticed their younger sister when she moaned. From his place on top of Sabrina, he looked back at her and sighed. "Kana...again?" He asked her...it wasn't the first time she had snuck into the room with them and masturbated while they made love, and it certainly wouldn't be the last, he knew that...still, he wished sometimes that his Little sister would just join in rather than watch. She was such a tease, after all. He could still feel Sabrina pulsing around him as he slowly pulled out of her and laid down on the bed beside her, giving Kana a nice view of his coated cock before left completely, mentioning their shopping trip today and a new Bikini for Sabrina.<br/><br/>When Kana was gone, Sam turned to his sister and kissed her lips gently. "That Kana....she's always had her eyes on us..." Sam said with a sigh, shaking his head. "But...I would like to see you in a new Bikini..." Sam said with a small smile, smirking at Sabrina's pink cheeks, her embarrassment at having been walked in on very evident. "Oh, Sabrina...you know Kana loves to watch...sometimes I wish she would just join in so we could show her how good it feels.." Sam said with a small shrug, kissing Sabrina's lips again.
