Samantha moved closer to Sarah, blushing as she pursed her lips and touched them gently to Sarah's own slightly moist lips, trembling with embarrassment as she kissed her 'mistress', Sam's heart pounding quite strongly as she forgot about the idea of having lunch with Natasha...having forgotten to ask her if she wanted to join the pair of them later, but there was always time for asking...right now, it seemed more appealing to have lesbian sex with Sarah in her older sister's office...something about it making her heart flutter with excitement.  She broke her kiss for a moment to whisper the words.<br/>"I love you Mistress Sarah...please..."  Her mouth quivered slightly as she struggled to say the rest.  "Please make love to your precious slave."  She finally spoke aloud, her eyes tightly closed and her face bright red with embarrassment.
