A special arrangement with my girlfriend and her mom

After having dinner with my girlfriend and her mom my girlfriend suggests I spend the night with her mom

My girlfriend and I were having dinner with her mom at her moms house the other day. Her mom was down and hadn't had a man friend in quite a while. I found my girlfriends mom quite sexy and sometimes mentioned to her jokingly that her mom was hot. Her mom looked like my girlfriend but with grey hair and a little smaller tighter body, which I imagined meant her pussy was a little tighter.
After dinner we were all chatting and my girlfriend suggested I should give her mom a hug with a mischievous look in her eye. I said sure and went over and gave her mom a long tight hug, holding her tightly.

"Why don't you give her a kiss?" my girlfriend suggested as she slowly spread her legs apart and had one hand on her pussy.

Still holding her mother tight I gave her a peck on the cheek. Then another. Then when I went for a third kiss her mom turned her head and we kissed on the lips.

"Yes that's it. she needs and deserves this," my girlfriend said, sliding her hand in her pants and playing with her pussy.

With my girlfriends encouragement I kissed her mom, slowly opening my mouth and slipping my tongue along her lips and into her mouth. Her mom responded with her tongue meeting mine and we were full on making out in front of my girlfriend, her daughter. My girlfriend was furiously rubbing her pussy watching us make out.

I continued to hold her mom tight while our tongues danced. I took my hand and placed it on her small tit giving it a squeeze. She responded by moaning into my mouth. I continued to play with her tits while we kissed deeply. Her hands wandered down and she started rubbing my hard cock through my pants.

"Here let me help you with that mum," my girlfriend said as she jumped up and got on her knees beside us. She unbuckles my belt and pulls my pants and underwear down exposing my stiff cock. She licks the tip of my cock and takes her moms hand and puts it on my cock and they both starts jerking me off together. Then she starts sucking my cock while I makeout with her mom. I take my girlfriends head in my hands and start to slowly fuck her face.

Her mom and I finally stop making out and she slides down beside her daughter and they both take turns sucking my cock.

"You too should kiss with my cock in your mouths," I suggest. After a moments hesitation my girlfriend starts french kissing her mom while they jerk my cock. "oh my thats so hot," i say as I watch them makeout. I would love to cum all over their faces as they makout but I hold off, hoping to find out if my girlfriends moms pussy is tighter than my girlfriends. I would love to pump my girlfriends mom full of cum, and watch her daughter, my girlfriend eat my cum out of her mom.

"Okay thats enough. I want to makeout with your mom again." I pull her mom back up and we start passionately kissing again while my girlfriend sucks my cock. "why don't you eat your moms pussy?" I suggest with a smile.

"Would you like that?" shes asks me.

"Ohh yes very much. Get her nice and wet for me." I respond.

"Are you going to fuck my mom?" she asks as she positions her mouth on her moms pussy while rubbing her own. I can tell she's almost as turned on by the idea as I am.

"If she wants me too," I respond as I makeout with her mom.

Her mom starts moaning and I see my girlfriend is licking her moms pussy. I keep french kissing my girlfriends mom as my girlfriend gets her mom nice and wet.

After awhile her mom whispers in my ear, "I want you to fuck me."

"I want to fuck you too. I want to fuck you and your daughter all the time."

We walk over to her bed and she lies down on her back and spreads her legs. I position myself between her legs and let her daughter guide my stiff cock into her moms tight wet pussy. I push my head into her mom and god is she ever tight. I take my time and slide my dick along her slit a few times before entering her again. This time I push deeper, and slowly start making love to my girlfriends mom. I lie down on top of her and makeout with her while we slowly make love.

"God your so tight. I want to fuck you all night." I whisper to her mom as I'm balls deep in her.

"Then do it. Fuck me all night. Make my pussy yours. We've talked about it and we can share you. Some nights you'll stay with me, some nights you'll sleep with my daughter. We're both yours you can make love to both of us all the time."

I continued to make love to my girlfriends mom until I finally came deep inside her. As soon as I recovered I fucked her again, and once more in the morning. I made them make out while I came on their faces and they cumkissed, licked, and swallowed my load. I continue to fuck both of them every day to this day, and decided not to tell my girlfriend that her moms pussy is tighter.
