Before I went to the bedroom with mom and sis, I went to the bathroom, took a piss then removed my pajamas. My member was rock-hard as I wondered which woman I would do first. I opened the door to the bedroom, but didn't see anyone on the bed. I walked in and called out. "Tina, mom?" with no response. I figured they'd decided on another bedroom, but walked over to the bed to wait.
Suddenly I felt arms wrap around my chest. I struggled to get out of the grip, but it only tightened the more I fought. "What the fuck, mom". Mom was the only one who worked out so much that she could hold me in place. But I froze when I felt something hard against my ass, coming to rest in the crack. It wasn't flesh, as it felt like hard rubber that had a head and a bumpy shaft.
"Time for you to feel like a women, Jeff," Tina said, coming out of the shadows of the dresser, completely naked. We know you like to fuck our asses, but you should know what it feels like," she said as she laid back on the bed and pointed to her cunt. "Come one Jeff, eat me."
I laid on my stomach and pressed my face against the outer labia.
"No no, my boy, up on all fours," mom's voice commanded. I couldn't disobey. I wanted to eat more of that sweet pussy before me. I squinted my eyes as I waited for the dildo to invade my ass, and it didn't take long.
My mom reached around my legs and stirred two fingers inside her daughter's cunt. She took one of the wet fingers and slid it into my ass. Then she squeezed a small amount of K-Y into the small entryway. Pressing against the hole, I wanted to scream out. I knew it would hurt, but I was also intrigued. Soon the muscle relaxed and the rubber cock began to disappear inside me. "Oh fuck!" I cried out. Tina grabbed my face and pushed it against her crotch. I began lapping and biting her clit. In fact, the more Tina pounded my ass, the harder I bit. I tried to keep my teeth from hurting her, but I knew it wasn't avoidable. The lady screamed and convulsed the harder mom went at it.
I felt like my ass was going to split in half as mom continued to fuck me with complete abandon. Then, after what seemed like an eternity, mom withdrew the dildo and began jerking me off. She pulled me away from Tina's twat and me stand on the bed above her face, all the time moving her hand quickly up and down my shaft. I knew I wouldn't last long at this rate, but the more I thought this the faster the lady pumped my cock. "Come on baby, cum on your sister. I want to see that hot milk coat her face and tits. I'll even clean it up for you."
Tina stretched her arms up and began massaging my balls, seeming to want me to unload, which I did. Spurt after spurt shot from my pee-hole as each drop splatted on her. Some on her face, her hair, on her tits. As my cock started shrinking, some jizz dripped onto her stomach. True to her word, when I was done, mom went down on her daughter, eating and drinking every drop of my cum, except for what was on her face. This she rubbed into Tina's skin as though giving her a facial. Then she kissed her and took her by the hand to the bathroom to shower together.

By time mom started making dinner the sun was starting to set. I asked mom what was for dinner. She gave a smarmy answer "Shit on a shingle."
This was very unlike her, making me think something was bothering her. "Mom, is everything okay?"
"Kind of. Tina had to leave, and Jenny might not be coming over. Damnit, I made enough food to feed all of us and have leftovers.
"That's okay, mommy, we'll have the same meals for a few nights. I'm okay with that. Where did Tina go? Did something happen?"
"Some crap with work. She said she might be back tomorrow. I know we all fucked earlier, but damn I'm horny again. I really wanted to have your sister again."
"Well, fuck, mom, you have me."
"I know baby, and I am happy you are here. But I'm afraid it'll take both of us to convince Jenny to hop into bed with us."
"Mommy, is Jenny moving or something?"
"No, why?"
"It's not like we don't have time to work on her. Tina's pussy can wait. So can Jenny's, for that matter."
Mom took out what looked like chicken parm from the oven, plated it, and we ate in silence.
"Mommy, I love you."
The older lady smiled broadly. I realized it had been too long since I'd said that to her. I meant it, too. Besides the great sex, she was still my mother. Only now I felt myself falling in love with her. Tina was still something of an enigma to me, and I didn't know if she was falling for me, too, or was just a fuck-buddy who happened to be her brother. I didn't know where Jenny fit in, either; just that I wanted to fit my dick inside of her.
The front doorbell rang at the same time as there was a knock at the rear entrance. "What the hell," mom muttered. She went to the back door while I traipsed the other direction. I opened the door to see a smiling Tina, who held her finger to her lips. We hugged and caressed each other's asses. We tiptoed into the living room, then T again held a digit to her mouth and disappeared into what appeared to be mom's room.
"Well, look who was able to make it after all," mom said, holding Jenny by the hand and leading her into the kitchen. "Sit, sit honey. Did you have a good day?"
"I did Barb. Went shopping. I think you'll like what I bought."
Other than that tease, there was a lot of small-talk surrounding dinner. I pretty much sat quietly, sizing Jenny up and down, wondering what part of her body I would taste first, wondering if I actually could get the chance. I wondered what Tina was doing. Was she masturbating or waiting to surprise mom, or both? In my mind's eye I could see my sister with her fingers teasing her cunt, pressing her thumb against her clit and going mad as she tried to keep quiet. I could see her ass bucking and jumping like a wild mustang who was being rode for the first time. Or maybe she was fucking herself with the huge dildo mom had driven into me earlier. Was Tina sticking a finger up her ass? Was she sniffing mom's panties, the ones she'd worn today, not only stained with her own juices, but also with a few skidmarks?
