Pussy

With her body atop Hannah's, Emma's cock had ended up resting against her slender thighs, the head nuzzling into the cleft between her soft ass cheeks. The soft, silky smooth skin sent thrills through Emma's shaft, and she realised she had already, unconsciously, began to rock her hips slightly.

Uncertainty briefly overwhelmed Emma, as she tried to work out what she could get away with. Thoughts of her little sister waking battled with the tingles of lust coming from her new appendage. Emma bit her lip, her eyes focusing on her sister's face. The panties remained in Hannah's slack mouth and no sign of wakefulness disturbed her beautiful features. Moving her face closer to her sister's, Emma felt her breasts crush into Hannah's back, nipples rubbing and stiffening in response. Desire won out, and Emma pushed her knees in between her sister's and parted them.

Emma was lost in a haze of lust and sensation. Her body pressed tightly to Hannah's sleeping form, their legs rubbing together, Hannah's slim torso trapped beneath Emma, and the tantalising warmth that teased her cock head. Shifting forward, Emma felt her hard shaft meet the damp flesh of her sister's pussy lips.
