In Laws

I had planned a surprise birthday party for my wife, secretly flying in her mom from one city and her 60 year old daughter, my stepdaughter, from another.

Her 53 year old married daughter and 55 year old son in law live across the country.

Apparently my wife got word of the planned surprise when her younger daughter couldn’t get time off work to visit, and spilled the beans. The day before the planned surprise party, my wife told me she was leaving for the airport, to fly out and spend her birthday with her younger daughter and son in law. “I’m sorry to spoil your surprise, husband,” she announced, “But I’m going to fuck my son in law. Don’t feel bad, I know my mom and older daughter will be here tomorrow, and you are welcome to fuck them both.”

I must have looks super mystified. My wife went on to say, “You know I believe variety is the spice of life, and the three of us will be back in a week to join the festivities. You and son in law can fuck all four of us as much as you want, then.”

That was the birthday conversation that changed our family life forever.

Almost as soon as my wife climbed into her airport taxi, my cellphone rang. It was my younger stepdaughter. As soon as I said “Hello,” she blurted out, “You must know by now mom is coming out here to fuck my husband for her birthday. Don’t wear yourself out too much fucking grandma and big sis, because I want some of that golden tongue and thick cock mom has been telling me about ever since she married you!”

Suddenly, the prospect of sharing four family gals with my step son in law didn’t seem so crazy after all.

Mother in law gad been widowed for several years by then, and harbored a voracious sexual appetite. The older stepdaughter was always intrigued watching me fuck her mother while waiting for her turn in bed with me. My wife’s son in law texted me: “Your wife is certainly a hot lover. She says she hopes her mom is treating you likewise. Your wife’s idea of sharing partners is awesome. My own wife loves watching me fuck her mom.”

The doorbell rang, and mother in law and her older daughter walked in. Before I could say anything, mother in law began undressing as stepdaughter remarked, “Don’t let any grass grow, or let brother in law get ahead of you. Get your cock in mom’s cunt right now!” We quickly climbed the stairs to the master bedroom, and stepdaughter began striping while I mounted mother in law on the king sized bed. I speedily got naked while mother in law spread her knees wide, and I mounted her and plunged my penis into her waiting vagina. Stepdaughter smiled as she heard her mom moaning: “Fuck me harder! Make me cum! Fill my pussy with your hot spunk!”

After ten minutes of energetic fucking, mother in law quivered as I ejaculated against her cervix. “I have been wanting your dick inside me like that for months and months,” she sighed. Stepdaughter pushed me off her mom, and took my penis in her mouth. “You and mom together taste great!” she announced, as she began sucking my hard on into her throat. “Fill my mouth and then my cunt, before you penetrate mom’s ass hole!” When I spewed my second load into stepdaughter’s mouth, she showed me the load on her tongue before swallowing it all. Then she mounted my hardening erection cowgirl style and whispered, “I want you inside me, filling my pussy like you filled mom’s.”

My first of a lifetime mother/daughter sex session was becoming the best sexual experience I ever had in my life. As my third load of spunk splashed against stepdaughter’s cervix, her mom encouraged, “Now take both our asses, as son in law is undoubtedly fucking your wife’s bottom as we speak.” Then she began licking my seed out of her daughter’s vagina as she used both hands to spread her bottom open for me.

“God bless your wife for gifting us unfettered access to your precious hard on,” mother in law sighed as I plunged my dock inside her rectum. “Then you can fuck my daughter’s bottom while she eats your semen out of my pussy and ass.” I wasn’t even feeling any more jealousy about my wife fucking her son in law – I was completely engaged in the moment, fucking stepdaughter’s rear end as she licked my two loads out of her mother’s nether regions. I could hardly imagine what awaited when my wife returned home with her younger daughter and her son in law.

Before this day, I had always known I was lucky to have a sincerely generous and helpful mother in law. I never suspected, however, how horny she could be. I began to understand why my wife had such intense needs for sex and sexual variety, and suddenly because very thankful that she decided
to include me in this new adventure.

The anticipation of my wife’s return home with her other daughter and her son in law was greatly overshadowed by the intense and exciting sex with my mother in law and the older of my wife’s daughters. We all got dressed if we needed to go into town for anything, otherwise we lounged around the house naked, admiring each others’ excitement and fucking every which way until we needed to nap or sleep. Both gals worked at keeping me sufficiently hydrated to be able to ejaculate whenever one or the other invited me to “cum inside” or “fuck my ass” or “give me some more of that delicious baby batter to swallow.” When my wife sent me videos of her fucking her son in law, we responded with videos of me fucking her mom. When her younger daughter forwarded videos of herself eating out my wife, we responded with videos of me eating out her big sister. There’s more to tell about what happened when wife, son in law and little sis returned to our house.
