Move on to her ass

As Emma looked down at the tight ass of her sister, her cock proved it's impossible nature once again by starting to swell. Despite two recent loads of cum, her cock was showing it's readiness to deliver a third, and Emma's eye's where on her sister's tight, virgin ass hole.

Emma knelt down behind Hannah, and traced a finger up her trembling thigh, collecting the thin line of cum that had begun to trickle down. Her tongue followed the same path, until it reached Hannah's slit. Emma's hands gripped the tight globes of Hannah's ass and opened them, allowing Emma to bury her tongue into her sister's cunt. Her tongue fiercely probed, caressing the clit before driving back into her sister's warmth. She tasted her cum as it dripped out, and the taste of arousal she was drawing from her sister. As Hannah's pussy opened up and became wetter, Emma slipped first one, then two fingers into her, whilst her thumb found Hannah's clit.

As Hannah's sobs turned to uncertain moans, as arousal joined her confusion and fear, Emma's tongue licked it's way up to the tight brown ring of Hannah's ass. Emma's tongue caressed it, probed it and lavished it until it was soaked in her saliva.

Shifting, Emma move up until her body was on top of Hannah's, rubbing her half stiff dick against the soft flesh of Hannah's arse and thighs. Emma's hands pulled the top away from Hannah's head, revealing her sisters flushed, tearful face. Emma's tits pressed against her sister's back, the nipples hardening from the soft friction with silky skin.

One hand was between Hannah's shoulder blades, whilst the other guided the head of her now fully hardened cock to rest against Hannah's slickened ass hole. A gentle push, and she felt the incredibly tight resistance before her cock.

"You better relax Hannah, your big sister is going to fuck that tight little virgin ass hole of yours..."

Emma's hand found Hannah's short hair, and yanked her head back until they were cheek to cheek. Emma's lips kissed along Hannah's neck, her teeth teasing the skin. As she reached Hannah's ear, her cock began it's push into Hannah's rear. Seconds passed, and Emma's cock made no headway. Then, suddenly, Hannah's resistance was overcome and the fat head of Emma's cock pierced her sister's ass hole. Hannah gave a pained yelp, as Emma froze, savoring the tight grip enfolding her cock head.

She did not pause for long, before her shaft began to drive deeper into Hannah's depths. Her thrust were slow, as the tightness of the formerly virgin hole prevented anything faster, but Emma thrilled at every sensation her little sister's ass was giving her. Once her slow pumping began, she taunted her whimpering sister.

"wow sis, you really have got a tight arse - I'm going to fuck you like this every day from now on. You're going to be my filthy little anal slut. This is what you get for being a little bitch, for every time you stole my things or argued with me!"

Hannah's vice like grip meant Emma wouldn't last much longer, and she knew it. Her thrusts took on a **** urgentcy, drawing shrill squeals from Hannah, and Emma bit down onto her sister's slightly freckled shoulder. Her teeth tasted her sisters soft flesh whilst she drove her cock hilt deep and began to unload into Hannah's ass hole.
