The girls took turns working on their deep throat skills and I wasn’t going to last much longer as I was pretty much groaning non-stop. I used both of my hands to the back of the twin’s heads to hold them in place while I gently fucked their faces.
As if on cue, Mom pulled her lips back from my balls with a pop and pulled back away from me pulling Julie’s lips off my shaft with her. My cock was bobbing up and down. Jesus Christ, I was hard as granite. Mom stood up and pushed herself up on her bed pulling me by my cock behind her. The twins parted and waited for their instructions from Mom with their fingers flailing through their sex.
Mom pushed me down in her spot on my back and threw her right leg across my hips and sat down compressing my cock against my stomach. She leaned forward and dangled her big tits a half inch above my lips. She waggled them from side to side and I pushed out my tongue to let her nipples ride over it. She groaned from the contact. I grinned up at her as she pulled back and sat up straight. The twins scrambled up on either side of me on their knees and sat down on their heels.
Mom said to no one in particular, “I’m gonna go first and then I’ve got to get ready. You girls can have him after I’m done with him. He’ll be able to get it back up for you.” I smiled at the twins as Mom lifted herself with her legs and reached under and guided my cock into her pussy. She dropped herself down my shaft as I heaved my hips up at her. She yelped with my thrust but she didn’t stop or even slow down. I had a grip on her hips to help pull myself in and out of her. She used her thighs to match my pace. Then she pulled herself forward and up my shaft and stopped and whimpered, “Piston-fuck me with just your knob.”
The twins looked at each other as if saying, ‘what’s a piston-fuck?’ They moved back behind Mom so they could watch my cock entering her sex and watched as I pulled my cock out to the ridge and took a firm grip on her hips and began firing my hips up and down as fast as I could, penetrating Mom with just my glans. I could feel the ridge of my glans rapidly sliding past the entrance to her vagina in both directions. Mom let out a scream and her head dropped forward. Her curly auburn hair cascaded down over my face. The twins bent down behind Mom to watch closer. Their fingers renewed their strumming with considerable vigor.
I was gasping for air from the activity and I was tiring. I couldn’t tell if Mom was going to have her orgasm like this or not. I knew that mine was approaching. Mom seemed to know too as she grabbed her tits real hard and worked her nipples as she snapped her head back throwing her hair back over her head. She gazed down at me. Watching her working on her nipples didn’t help my situation any and I made one last attempt to push her to an orgasm.
I could see her orgasm building by watching her eyes. Her head cock slightly to the left and she sucked her lower lip between her teeth. Then her torso rolled to the left following her head and finally she sat down hard on my cock stopping my piston-fuck. I kept trying but then I realized that she wanted full depth powerful thrusts from me and she exploded on the first one. I was seconds behind her and cum blasting into her caused her to scream with each one until they lost their power and finally just drooled out of my cock. Her clenches seemed to be milking the cum from me.
