Using Hannah's lips

Emma's gaze shifted from her bedraggled sister to her own body. Their combined juices covered her now softened shaft, making it shine. Her body was coated in a thin film of sweat, but tiredness had competition from lust as she saw the soft cock begin very slowly to revive.

Breathing heavily, Emma decided she would have to find a way to satisfy it which wasn't so strenuous - for her at least. Climbing on to the bed with Hannah, she enjoyed the view of her sister's overwhelmed body. Her slender, pale legs hung over the edge, her panties visible on the floor below. Emma's eye's trailed up the alabaster skin to where they joined, a soft triangle of red curls topping the deep red of Hannah's well fucked pussy. The same juices that coated Emma's cock marked her sister's thighs, a thick bead of white cum beginning to slip free from the tight lips.

Emma's attention passed over the soft stomach of her sister, briefly lingering on the two small domes of her tits, before reaching her face. Tears ran down Hannah's cheek as she tried to process the shocking experience, her eyes' only now beginning to focus.

Movement in the corner of her eye drew Emma's attention. Hannah's arms, still trapped in her work t-shirt, were trying to wrestle themselves free. Acting immediately, Emma swang her leg over Hannah, pinning a wriggling arm. Moments later, her other leg pinned Hannah's other arm, and she straddled her defeated sister's head as she looked down the length of her exposed body.

Emma seized her little sister's lower jaw in one hand, her nose in the other, easily prising open the enticing oval of Hannah's lips. Her semi-hard cock immediately slid between them.

"Now clean me, bitch"
