Going home and resting up

As the sisters thought you studied Michelle's body. She looked a lot like her sister, but a little more curvy and a little shorter. Wondering again how she would be at sucking cock, your mind started getting away from you. Luckily, Molly's barstool scraping across the floor pulled you out of that reverie.

"Can I drop you off somewhere?" Michelle asked.

"Yeah, that'd be great" you said.

"Alright, come with us then" Molly told you. You took your crutches and followed Michelle, keeping your eyes on her perky ass. Molly was too busy keeping an eye on your movement so she didn't notice. You were getting hard in your pants all over again, just like you had before. This time, though, it made you feel guilty. After all, you were dating Molly, not her sister. Yet all you could imagine was fucking that teen body hard. You sat in the back of Michelle's car, awfully aware of the two gorgeous woman that you both found very attractive.

After they had dropped you off you went to bed where you just needed to jerk off. You loaded up some videos of hot blondes and before long you were stroking to a threesome involving two blondes and a hung guy. After jerking off to it and falling asleep, you had a pleasant dream that ultimately led to you having an actual wet dream.

Molly was on her knees in front of you, slobbering all over your cock as she moaned happily.

"You like that, baby?" she asked.

"Of course I do" you replied. "Can't you see how hard I am?"

"I don't know, it feels like you get harder for my baby sister than for me" Molly replied.

"Are you jealous of her?" you asked.

"A little" Molly admitted. "I see you looking at her when she's walking through the house naked."

"Molly, look at me" you said. She did. "I married you, didn't I? Not Michelle. Just because I managed to make her my slutty **** doesn't mean I don't love you."

"I guess" Molly said, a small smile coming to her face. You pulled her up to her feet then into your lap, where she sat with her mound resting against your cock.

"Just because I turned your baby sister into my free use pet doesn't mean I love you any less. Besides, you know how fun it is to fuck her with me" you told her. The smile got bigger.

"Yes, I do. I love how we turned her into our personal ****" your wife said. Smiling broadly now, she licked her lips. "Michelle! Come here!" she then called.

"Yes, mistress?" Michelle said as she came from the kitchen wearing nothing but an apron tied around her waist. Her big teen...no, no longer teen. She had just turned 20, after all..Her big breasts jiggled with every step she took, making your cock throb.

"Why don't you go get your strapon?" you whispered to Molly, who grinned and nodded. If there was anything that could take your wife out of her doubt about your love for her it was dominating her sexy little sister. Then, to Michelle you said: "Take that apron off. You won't need it." Molly walked off and went to get her strapon harness while Michelle got in your lap, starting to make out with you for as long as she could before her big sister came back to claim her rights.
