"Oh God, yes. Fill me with your cum. I'm such a dirty slut. Fuck me brother. Fuck your sister into motherhood."
I unleashed a second load into her pussy after hearing that. I looked up at my wife and she was sitting on that mother fucking black cock. Her head was thrown back and her eyes were closed. She was mumbling and crying and shaking all at the same time. When she lowered her head, all I could see were the whites of her eyes. She soon collapsed in the chair.
My beloved sister-in-law was out too. I could hear her steady, labored breathing, so I moved off of her. She didn't move. I massaged her back, ass and legs but she wasn't moving. My cum was leaking out of her cunt and matting her pussy hair. I pushed a finger into her pussy and spread the cum over her asshole. I lubricated her asshole and started to finger fuck her ass. She pushed back against my finger and groaned. I continued to finger her asshole, stretching it, making it ready for that black cock that was filling my wife's pussy.
I worked a second finger into her ass. She groaned louder this time. I scooped some more of my cum from her pussy and got her asshole nice and lubed. I looked over and noticed my wife had regained her senses. She was watching me finger her sister's ass. I motioned for her to bring the dildo over to me. She had this devilish smile on her face.
Sandy positioned herself at the head of the bed. She motioned for me to turn Sammie around so that her face was close to Sandy's pussy. I told Sammie she had to move and she turned right into Sandy's cunt. She mumbled something softly, but I didn't catch it. Sandy looked down at her sister and smiled.
"Sammie honey, would you like to taste this nice hard, black cock? Hmm, would you sweety. It's right here in front of you."
Samantha raised her head and moaned. My wife took that dildo and pushed it back into her pussy. She then removed it and held it out for Sammie to suck. Sammie just opened her mouth and took it in. Her asshole clenched around my fingers. I heard a grunt and watched as Sandy started to face fuck her sister with that black cock.
Sammie tried to open her mouth wider. I heard her suck in air whenever Sandy withdrew the dildo. Her asshole was now clenching my fingers in a nice steady rhytym. I replaced my two fingers, in her ass, with my thumb and then pushed my other fingers into Sammie's cunt. The effect was immediate. Sammie let out a whoop and dove right down to the balls on the dildo. Her pussy was spasming wildly around my fingers and her asshole trapped my thumb. I looked up at my wife and she was pushing the dildo faster and deeper into Samantha's mouth.
"Fuck her again." My wife commanded.
I withdrew my thumb and fingers and spread Sammie's legs from behind. Her pussy and asshole were contracting wildly. It was quite fun to watch. I rubbed my cock against her slit and pushed forward. I sank balls deep on the first push. Sammie continued to thrash about the bed. I motioned for Sandy to take the dildo out of Sammie's mouth and to give it to me.
When Sandy took the dildo out of Sammie's mouth, Sammie cried out, "No, I want to suck it. Please! It feels so good in my mouth."
Sandy handed me the dildo, looked down at her sister and snarled, "You want something to suck? Suck my clit you filthy, little whore!"
Grabbing Sammie's hair, Sandy pulled her face to her pussy. Sammie didn't put up much of a fight and just starting licking and sucking at Sandy's pussy for all she was worth. Sandy pressed her sister's face against her cunt and moaned. She wasn't going to last too much longer at this rate. I had to work fast.
I pulled my cock out of Samantha's pussy. I replaced it with the black dildo. Sammie squirmed as the extra large cock made it's way into her well worn cunt. Sandy continued to hold Sammie's head against her slit. I worked that black dildo in and out of Sammie's cunt until it was well lubricated. I pulled it out of Sammie. She moaned in frustration, until I pushed my cock back into her.
I looked up at my wife and she nodded her head yes. Using my left hand, I spread Sammie's asscheeks. I think she knew what was coming because she tried to squirm away from me. Between my cock in her pussy, my weight on her legs and my lovely wife's hands in her hair, poor Sammie wasn't going anywhere. I took that nice, thick, black dildo and started to push it into Sammie's sexy ass.
She tensed up right away, but I was persistent. First, the head popped past the anal muscle ring. I let her asshole adjust to the thickness. I continued to pump her pussy. Sandy let go of Sammie's hair and let her adjust her pace accordingly. Sammie would whimper every now and then, but she was really busy sucking her sister's clit. My wife lifted her legs and allowed Sammie room to play. I watched enthralled as Sammie now worked my wife's asshole with her tongue.
I pushed the dildo in some more and Sammie groaned. Sammie replaced her tongue with a finger up Sandy's ass. Sammie began to lick and suck on Sandy's clit. Sandy's eyes rolled back into her head again and she came. Sammie just kept sucking on Sandy's clit. Sandy let out a low moan and dropped her legs. She lovingly caressed Sammie's hair. I looked down and noticed that the dildo was buried in Sammie's ass.
As I stroked my cock in and out of Sammie's pussy, I started to stroke her ass with the dildo. She was uncomfortable at first, but, after a few minutes, she was actually pushing her ass back to meet my thrusts. I looked at my wife and gave her a smile. I mouthed to her, "One more switch. Sit on her face when I flip her" Sandy nodded her head that she understood and we went for the switch.
I pulled out of Sammie's pussy, much to her dismay. Sandy also pulled her face from her cunt and we quickly rolled Sammie onto her back. The dildo was now pressed firmly into her ass and prevented from coming out by the bed. I moved between Sammie's legs and pushed my cock back into her. She came immediately. Sandy then spread her legs over Sammie's head and sat down. There was a muffled moan and then Sandy began to hump her sister's face.
I maneuvered myself so that I could suck on Sandy's tits while still fucking Sammie. My wife was moaning and grinding her hips around her sister's face. I started to pump Sammie's pussy faster and faster. I wasn't able to hold out any longer and pumped another load of my cum into her cunt. I felt Sammie stiffen below me, signaling her orgasm. My wife rolled off of Samantha's face and collasped on the bed. I leaned down and sucked some more milk from my sister-in-law's titties. I too rolled off of Samantha. I removed the dildo from her ass and cleaned it off in the bathroom. I then used it to stuff her cunt to prevent my sperm from escaping their destiny.
I looked over at Sandy and Samantha. They looked so cute sleeping together on the bed. I lay down on the floor and feel asleep quickly. I secretly hoped my seed wouldn't take, so we could do this again.
