I woke up to an empty bed feeling refreshed and rejuvenated after fantastic sex the night before, and a chance to sleep in later than usual. I tucked my morning wood into my waistband before venturing out of the guest room to find my wife on the floor with our kids while her mom was watching from the nearby kitchen. My wife was in a white tank top and shorts, about halfway done with her coffee, while her mom was in her typical for her, yet uncommon for most women, black morning dress with a fresh new steaming cup of coffee. I waved to my mother in law before giving my wife a kiss hello and sitting down beside her to say good morning to the kids when my father in law walked in. "Mom and I are walking up to the park to get some exercise, who wants to come with us?" he said in his usual, cheerful morning voice.
"The kids do!" my wife answered.
"You're going now?" my mother in law said surprised. "I haven't even gotten dressed yet."
"Well you better hurry," he responded.
"I'm not going," my wife said decidedly, giving me a quick raise of her eyebrows.
"It's too hot for me," I quickly agreed.
"Ok well you two get the kids ready while I go change and we'll bring them with us for a few hours while you stay here," my mother in law said excitedly before running into her room and shutting the door behind her.
Without trying to seem too eager my wife and I got the kids ready for the park in record time as my in laws were ready for their morning in the sun. My mother in law changed out of the black dress with the leg slit and into a tight blue tank top that I now loved equally as much since it showed off her busty chest just as well. It almost would have felt like a missed opportunity to see my wife's mom in that tank top for an extended period of time if I hadn't known that my wife already had some good ideas of her own. We all said our goodbyes and I took one last good look at her moms chest before we shut the door and turned to each other eagerly.
"I need another coffee before we do anything else, could you please make us some?" my wife said before giving me a kiss and scampering off. "Thanks, I'll be right back." I made our coffees and tried to imagine what exactly my wife had in mind when she said "before we do anything else."
I was sitting at the table with our coffees when I finally felt a hand on my shoulder followed by a nibble on my ear. The long brown hair draped over my shoulder was a familiar sight I loved to see but when I turned to face my wife I was still caught off guard. My cock instantly got noticeably hard in my shorts as I realized that my wife was now wearing the tight black unusually sexy morning dress with the leg slit that her mom had just taken off. The same flattering dress her mom wears every morning on vacation that I loved and appreciated very much. "I'm glad you like it," my wife said stepping back and grabbing my hand. "Come with me."
I was in for another surprise when my wife didn't bring me into the living room or our bedroom but instead brought me into her parents bedroom, pushing me onto the unmade bed. "My mom sleeps on this side of the bed and I figured we would try a new spot in the house," my wife said while straddling me. I grabbed her ass and kissed her before she pulled back and exposed one more surprise she had for me. "I found this on top of the hamper and thought you would appreciate it," she said as she slipped a black bra I did not recognize off her chest and shoved it in my face, pushing me to lay down on the bed.
While her moms warm bra was still on my face my wife started riding my big hard cock, slightly lifting the dress to give me a good view before lowering it again to lightly drape across my waist. She was so wet on top of me while I was intoxicated by the new environment and the overwhelming smell of her moms perfume throughout the room. I sat up again and buried my face in my wifes busty chest before lowering the neckline of her dress and taking turns licking each perfect nipple, lightly pulling her head towards the ceiling by her hair.
I let my wife ride me for a little while before I rolled her off of me and had her get on all fours, with her head towards the headboard. I got behind her and slipped my big cock back inside her, leaning over to grab her shoulders so I could get as deep as possible. She moaned and arched as her tight pussy struggled to accept a size she so desperately craved. As we got comfortable again I pulled her head back by her hair and rammed her repeatedly, making the bed squeak and the headboard bang against the wall. The bed was relatively quiet for the pounding it was taking and I couldn't help but wonder how many times my mother in law had been fucked in this exact spot while we were visiting and I unfortunately hadn't ever heard a thing.
It was at this moment that I noticed the picture on the bedside table of my wife and her mom in their bathing suits from a family trip they went on together before we were married. Seeing my wifes mom watching me fuck her daughter immediately had extreme results as I now felt like I not only had to please her daughter, but had to put on a show for her as well. I ran my hands along the dress, as if to point it out to my mother in law, before grabbing my wifes hips and thrusting hard. The extreme results quickly became evident as my wife began to cum shortly after I noticed the picture, moaning and jerking while slamming her ass up against my pelvis.
Now that my wife was taken care of it was my turn to finish. "Don't cum on the dress," my wife warned unexpectedly. "Cum on the sheets instead." She moved up next to me while placing a wet hand on my cock and whispering in my ear. "Haven't you always wanted to cum on my moms bed? Now when she goes to sleep she'll be covered in your cum. If you get some on her pillow you'll basically have cum in her mouth. Her drool will mix with your cum, just like you've always wanted. Maybe it'll even get her to subconsciously think of you. Maybe she'll picture you fucking her from behind in this same dress."
My wife was taking turns between whispering in my ear, kissing my neck and licking my nipples while stroking my throbbing cock. "She's watching us," my wife said as she nodded to the picture on the bedside table while she picked up her moms bra and wrapped it around my cock. "Cum for her." I did. I shot a load that reached the pillow before making its way spurt after spurt back to my balls near the foot of the bed. My still enlarged cock hung between my legs with cum leaking out of it onto the bedsheets while my wife kissed me and rubbed my balls in a congratulatory manner.
