A helping hand, and a little head

"Hannah..." Emma just smiled as she reached again for her little sister, trying to calm her. The poor girl just stared at her however, still whimpering softly while her cock was reaching it's full and impressive length.

Then she tried something quite unorthodox, in the means of calming someone down, and gently slid her own slender fingers around the very tip of that massive shaft.

"Oh, god...!" Hannah gasped at the soft touch, but was already backed into a corner so she couldn't pull any further away. "E-Emma...?! What... are you doing...?!"

"Just relax!" Emma hushed her, while continuing to massage the fat head of her sister's cock. And then she pressed herself closer to the other girl, as to keep her upright on her trembling legs. "Let me handle it...!"

"But...?" Her sister tried to object, but then gasped and moaned as a shiver of pleasure ran up her spine from the 'helping hand' she recieved. From that point she stayed rather quiet and passive, and eventually removed her own hands from her shaft to give the other one full access, though she remained rather tense...

"How... is this actually helping...?" She mumbled after several long moments, clearly flustered and with her cheeks blushing deep red in a mix of arousal and embarrassment.

"It's not." Emma confessed, with another grin on her lips, and then shocked her little sister even more by squating down on the floor and taking as much of her big nice cock into her mouth as she possibly could. "Mmmmh!"

"Oh, god!!" Hannah gasped, while pushing herself back against the wall, and then found herself grasping at her sister's long hair while she started to work her lips and tongue around her massive cock. At first she tried to dislodge her, but then just held on like her life depended on it, while her moans and gasps were turning into involuntary squeals of utter pleasure.

Soon enough the girl was **** to give in to her sister's skillful performance, and with a final throaty groan she started shooting her load directly into the back of Emma's warm mouth. And she was cumming quite a lot as well, more than Emma had ever tried to swallow in a single go, and within a moment the sticky white stuff was starting to dribble out the corners of her soft lips. In the heat of the moment she didn't care one bit about the mess however, and finally Hannah's new sack was entirely drained, while their content was dripping from Emma's chin and staining the front of her shirt.

"Oh, wow!" Emma chuckled as she finally pulled free, licking her lips while staring down the length of her sister's slackening member. Then Hannah slowly dropped down onto her knees, completely exhausted, and couldn't even try and object as Emma pressed her sperm-coated lips to her own...
