I turned my head to see Mom sitting in the arm chair over in the corner. Pam snapped her head around and froze when she saw Mom there, completely naked and touching herself. Mom had a big smile on her face and said that she just couldn't help herself as she continued to run her fingers over her kitten. Pam started to panic and tried to get up off of me, but I held a firm grip on her wide hips and just held her down, planted on my cock. She couldn't say a word, she simply blushed as I started to move, running my still hard member up and down a little inside of her while she sat on me. I rolled her over onto her back and started to slowly slide all the way out of her, and then ease all the way back inside. Mom got up from her chair and came over to sit on the end of the bed, getting an up-close view of her son's hardness penetrating her sister's kitten. She quietly encouraged us, saying that it looked amazing, and how it was making her wet. I felt her fingers start to massage my balls as I continued to slowly play with Aunt Pam, who had her eyes shut tight and her head turned to the side. I am sure she was trying to process what was going on, and how she had gotten to this point. Pam finally asked Mom what the heck was going on. Mom just played innocent, saying that she was going to ask her the same thing when she came across the two of us playing in bed. She went on to say that she wasn't able to talk when she saw us, but she was so turned on that she had to take care of herself. Mom then said that she could see my cum all over me, and that she was dying to taste it. I got up off of Aunt Pam and moved off to the side. I held Pam's legs apart and told Mom that if she wanted to taste it, that she would have to lick it off of Pam's kitten first. Mom looked at me, stunned as I held a smile on my face from ear to ear. She was speechless as she looked down at her mature sister's shaven kitten, with my huge load of cum still dripping out of her entrance. Mom took another quick glance up at me, and then looked down again as I slid my hands down Pam's thighs, opening her lips to give Mom a better view. I could tell that Mom had never entertained the idea of being with another woman, but I also knew that she was very eager to taste my cum again. This was a very intimate and private act, and I figured that there would be no woman that she was more intimate with than her sister, so there was no woman that would be better for her to share this with! Mom slowly started to move into position, getting closer to Pam's still throbbing womanhood. She crept in closer, until she was finally in position, with her face centered between her sister's legs. Mom stuck her tongue out, and picked up a couple drops of cum that were off to the side. She moaned a little when she tasted what she had been wanting for days, I'm sure. She licked again, starting on the outer lips, cleaning up what had squeezed out to the sides during sex. Once she had gotten all of that, she moved down to catch the stream that was slowly running out of Pam. Mom savored the taste of my cum, devouring every drop that she was able to get to. She pulled away when she saw that she had cleaned up all of my cum from the outside of Pam's kitten. I reached in closer and spread Pam open more, revealing a pool of my cum, still resting inside of Pam. Without hesitation, Mom went back in, pushing her tongue inside of her own sister, to get her son's cum out of her entrance. Pam moaned when she felt Mom's tongue penetrating her. To my surprise, when Mom stopped because she had gotten all of the cum out that she could reach, Pam clenched down, squeezing more of my cum out of her kitten, bringing Mom right back in to lick her some more. I watched in amazement as Pam kept squeezing my cum out, little by little, to keep her younger sister coming back for more licking. When it looked like Mom had gotten every last drop out of Aunt Pam, I told Mom that it was time to be a considerate playmate. I moved my fingers up, pressing down the lips around Pam's clitoris, making it stick out. Without hesitation, Mom came in and started to suck on her big sister's pearl. Pam immediately started moaning when she felt Mom's lips on her sensitive love bud. Mom let her female instincts take over, and started to pleasure Pam as if she had been doing it for years. I moved back a little bit so that I could take in the amazing show. I might have been dreaming, watching two curvy, mature women engaged in pleasing one another. That is to say nothing about how kinky it was that they were sisters, let alone that it was my Mom feasting on my Aunt. Pam was already moaning when I took one of her nipples into my mouth. I started to tease her breasts as Mom kept her attention on Pam's kitten. Pam kept moaning louder and louder, and when she finally was able to manage another orgasm, it just made Mom even more intent on her pleasure. I got up from Pam's breasts, and straightened up to get another full view of what was happening. When Pam looked over and saw that my erection was still standing straight up, and that I still had some of our combined juices left on me, she grabbed my leg and pulled her head over, putting my manhood back in her mouth. She moaned in appreciation as she enjoyed the tastes that we had made together. She had just barely finished cleaning me up when she started to get gripped by another orgasm. Pam let go of me and laid there paralyzed as mom kept working on her kitten. I got off the bed and moved around to the end, where Mom's round rear was sticking over the edge. She was dripping juices so much that there was a small puddle on the floor. I wasted no time sliding my cock inside of her, squirting more of her juices out as I bottomed out inside of her. Mom's kitten had recovered fully form the abuse it had endured the other week. I stroked lovingly into Mom while I looked at the spectacle before me. I tried my best to keep from bumping Mom around too much, so she could keep pleasing Aunt Pam. I was shocked that the next time that Pam climaxed, Mom went right ahead and joined her in the orgasm! I was even more shocked with they came together the second time too! I started to pick up the pace, and since Pam was pretty worn down, Mom ended up cumming on my hardness by herself for the next few orgasms. I could feel the wetness on my feet as I stood in the puddle that Mom had made. After a few more minutes, I was ready to release my second wave of cum, and this time it was going inside Mom! This wasn't "Angela", this was MOM that was going to receive my seed! I took a firm hold of that beautiful ass and started to pound it. Mom stopped working on Aunt Pam, and just put her heard down, moaning loudly. Pam slid away from Mom and got off the bed. She was weak in the knees but she leaned against the dresser while she watched her Sister get pounded. Our bodies slapped together loudly as Mom started to scream. She squeezed my cock tightly as she climaxed on her son one last time. I kept stroking into her incredibly strong kitten, making the most of her wetness. Finally my knees went weak as Mom took all of the seed that I had left in me. I held still for a while as we soaked in the afterglow of our passionate sex session. I motioned for Aunt Pam to come over as I slowly pulled my still hard cock out of Mom. When she got close, Pam bent down get a good look at my hard member slowly sliding out of her sister. When if finally came out, some of my cum started to leak out of Mom's kitten. Pam immediately put her hand out to catch it from dripping on the floor, and then savored it as she licked it off of her fingers. As soon as her fingers were clean, she put her hands on Mom's ass, and dropped to her knees right behind her, almost shoving me out of the way. Pam pushed her mouth tight up to Mom's shaven kitten and started to return the favor, cleaning all of my juices from her lips before starting to penetrate inside of her sister using her tongue. Mom followed suit as well, squeezing down to get my cum to where Aunt Pam could lick it out of her. I moved around and got back up on the bed, kneeling in front of Mom. She lifted her head, and instantly started to lick our juices off of my member. She slid her tongue and lips over every inch of it, making sure to devour every last drop. Once she had gotten all of the juices, she started to suck on the head while she enjoyed the pleasures that Aunt Pam was dishing out. Mom let my head slip from her lips as she clenched up in another orgasm. I watched the top of Pam's head move around behind the large creamy cheeks of Mom's rear. I reached under Mom and started to tease her nipples while she enjoyed her sister's tongue in her kitten. After two more orgasms, Mom was worn out. She rolled over onto her back and Pam got up and joined her, laying on the bed beside her. They hadn't had any alcohol, so they must have been drunk with passion as they turned toward each other and started to intimately kiss...
