Nikki smiled against her brother's cock as he groaned and giggled as he called her sexy.  "You aren't half bad yourself," She teased him, keeping her eyes on his as her lips and tongue expertly moved over his cock.  She didn't even have to watch what she was doing.  She knew his cock so well it was more exciting to her to watch his face than her actions.  She could feel his cock twitching in her mouth and she made several short strokes up and down his shaft each time her mouth  took him in as far as his cock would go.<br/><br/>With her free hand, she cradled and fondled his sack, feeling the contractions there, she knew he was close.  Especially when he begged her to keep going.  Instead, she slowly pulled away from his cock, she didn't want him to go just yet.  Nikki placed a kiss to Andrew's hip and slid up his body, her tongue playfully flicking against one of his nipples before she sat her pussy down along his cock, sliding along the length of it as she lowered his lips to his for a deep kiss.  "I love you so much." She whispered against his lips before reaching down to grab his cock, slipping it into her pussy again.  She wanted him inside her again and was very happy it usually didn't take much to keep him hard for her.  She was insatiable when it came to her brother and it was like she could never get enough of him.  Bracing her hands on his chest, she pushed herself into a sitting position, resting on top of him with his cock deep inside her and just barely squeezing her pussy onto his cock, a teasing smile on her face as she looked down to him.
