Helen's mouth

Clair looked back and realised she'd leaned back far enough that her pussy was now brushing lightly against her still sleeping sister's mouth. She'd never had sexual feelings for her sister before, but the sight of Helen's mouth pressed against her pussy stirred something in her she'd not felt before and she began rubbing her slit back and forward enjoying the illicit feeling. Gradually as she rubbed her sisters face harder and harder with each stroke she relaxed with the increasing pleasure, her face lowering to the shaved treasure in front of her.

Joe meanwhile stood enthralled, hardly able to believe his wife was riding her own sisters face. His cock stood erect, hard, and throbbing in front of him even though he'd totally forgotten about stroking it. He leaned forward and taking himself in hand, offered his cock to his wife.

Clair looked up as Joe pressed his cock against her forehead, realising she'd been staring at her sisters pussy. Joe's cock was at least as swollen as she'd ever seen it, if not more so, in all the time they'd been together and she quickly took him in her mouth, sliding her tongue around the head before sucking him deeper and licking the underside of his shaft. Clair lowered her head, resting her chin on her sisters mound as she sucked her husband, enjoying the taste of the smooth slippery fluid beginning to seep from him.

Joe watched his wife for several minutes; he always loved the sight of his cock disappearing into her mouth, or pussy for that matter, but his sister in law's pussy was only an inch below so he pulled his engorged rod out.
