Emily makes her move

Figuring that she had **** Emily stood and rushed Sarah. Sarah was not expecting it didn't have time to react beyond a yelp of surprise.

Emily grabbed Sarah's wrists and held them above Sarah's head. Sarah felt her stomach dampen as Emily's cock pushed against her dripping pre. "No you - mmmmm." Emily covered Sarah mouth with her free hand cutting off her speech. But with both hands full she couldn't use the marker.

"Alex hold her wrist." Alex quickly climbed up to the bed and held Sarah's wrists with both of hers a look of **** concentration painted on her fact. Sarah started thrashing. Alex was barely about to hold the stronger woman down but for now she held. The thrashing also **** the strap-on to rub against the length of Emily's shaft, it did give Emily a sudden desire to rub her cock against a real one at some point but that was for later.

Emily took out the marker and tried to rush through her options. She settled on giving her self more time. 'SLEEP'. She wrote it on Sarah's shoulder and Sarah immediately stopped struggling, going limp and letting out deep breaths. Emily carefully pulled her hand off Sarah's mouth and when she didn't wake and scream Emily climbed off her and looked down at her naked form with the strap-on standing straight up and Alex still holding Sarah's wrists.

Emily tried to think but all her thought could managed to do was combinations of fucking Sarah or fucking Alex. With Sarah sleeping Emily did feel a little weird about pounding the her. Alex on the other hand would be way more than willing to accept Emily's cock.

Emily reached over and grabbed Alex's chin forcing her face away from Sarah and towards Emily. She then pulled her sister close and started to kiss her. Her tongue invading her little sister's mouth as soon as their lips met. They broke their kiss and Emily looked down at Sarah's sleeping form.

"Get on top of her." Emily whispered moving back so Alex could position herself. She watched her little sister climb over Sarah and lay down on top of her. Once she was ready Emily grabbed her sister's legs and moved them to spread over Sarah's. The strap-on was standing, pressed against Alex's pussy, but not quite tall enough to cover Alex's butt.

Emily giggled at the image, as if Sarah's strap-on was saying, fuck her here. Emily was happy to oblige. She did still want to say her little sister's pussy for a special occasion. Also she wanted to prove Sarah's comment that Emily couldn't control herself enough to not fuck Alex's pussy wrong.

"OOoohhhh God big sis." Alex groaned out as Emily entered her. There was still lots of lube there so Emily just stared to grind against Alex's butt. "mmmmm that feel more natural." Alex murmured making Emily feel even better than Sarah.

Emily started to thrust and was soon joined by Alex eagerly pushing back trying to get more dick inside her as quickly as possible. "That's right little sis, you love you big sisters cock don't you." Some part of Emily needed to claim her sister once again after watching Sarah pound her.

"Yes I love my sisters cock sooo much, fuck my ass hard make it remember who's boss." Alex let out.

As they fucked Emily felt the strap-on brush against her pussy. Getting an idea she pushed all the way inside Alex and reached around behind and between her legs to grab the strap-on. She moved it back slightly until she felt a thrill of pleasure as it ran against her pussy. Once it was in position Emily lowered herself feeling the strap-on enter her.

"Ohhh fuck me." Emily moaned as the feelings of both filling up her little sister and being filled up over took her brain. She did the best she could to try and experience both, bounce on dick and fuck slutty ass. It didn't work all that well, her pussy felt better than her cock, probably because she had been cumming over and over again over the last few days and never with her pussy.

"HARDER BIG SIS! Stretch out my ass!" Alex shouted. Emily looked down and saw Sarah's still sleeping face next to the back of Alex's head. Emily reached down and grabbed her little sister hair moving her head above Sarah's. She heard Alex's begin kissing Sarah's **** lips as soon as they were in range.

"Good... oh... girl little... fuck.... sis." Emily tired to get out between her moaning. The double fucking felt stupidly good. "You're my... oh god... cock sleeve."

"Yes. I 'm my big sis's cock sleeve." Alex fervently agreed. "My ass was made for her cock."

"Good." Emily stroked Alex's hair as if to pet her little sis. "I'm going to cum." Emily thought she was last longer but the pussy fucking was really getting to her, she would definitively need to experiment with this later on.

"Fill me up big sis. fuck you load into my ass give me what Sarah couldn't." Alex's begging pushed Emily over the edge and hearing that she was doing something Sarah never could made her shove as much of her cock as deeply inside Alex as she could.

Alex lurched forwards on top of Sarah as her ass was filled up with cum. Feeling her sister cumming made her grab the bed sheets and shake her own orgasm out.

"WHAT THE FUCK!"
