An old fling (cheating turns to threesome, long story, cuts to the chase quickly, MFF)

“Good night love,” my girlfriend leaned down to kiss me before she headed off to bed. Her curly, shoulder length hair spilling down around her face and onto mine. She was dressed in ninja turtle pajama pants and a spaghetti strap top. I pulled the front of her shirt down to expose her c-cup tits and buried my face in them. Our roommate on a perpendicular couch laughed, “goddamn dude just go to bed with her now.”
“Oh, sometimes things are worth waiting for,” I smiled. She giggled, her nose wrinkled, her face in an adorably playful smile. She went to the bedroom. I cracked a beer and planned to fuck off on my phone for awhile before joining her. My cock twitched, knowing she would be naked and willing to fuck as soon as I woke her.
Twenty minutes later I got a text from an old flame of mine. About five years ago we had shared a wonderful summer together before she moved away, across the state. She told me she was in town and wanted to see me. I couldn’t say no. I still had her nudes on my phone. Every couple of years we had gotten together to fuck like old times, but I told myself it wouldn’t be like that this time. So like a genius, I invited her over. It was not a strange thing to have guests over at my house at literally any hour. Me and my roommates had a “door is always open,” policy, though metaphorical because it was always locked, “for the safety of would be invaders,” we told people.
She showed up just a few minutes later. When I opened the door I was taken aback. She was wearing a tight fitting yellow dress that hugged her tight, lithe body. She had perky little a cup tits that pressed against her dress, clearly not trapped by a bra. She had black stockings and high heeled shoes, accentuating her tight and toned legs. Her hair was long and fell halfway down her back in a straight, silky blanket. She wore dangly, silver earrings that glittered in the light and mesmerized me like a cat with a christmas tree. She had very little make up on, just enough to accentuate her natural beauty. She had done these things for me, she knew the details I liked.
“Hey handsome you gonna just stare at me with that gaping jaw or let me in?”
I swear the angel and the devil appeared on my shoulders, but both of them had hardons and didn’t say a thing. I regained my composure and ushered her through the door. My roommate stared at her for a moment, taken aback as well.
I offered her a seat, and then a drink. She asked for wine, knowing I always kept a few bottles in hand.
We sat and chatted for awhile about how things were going. My eyes feasted on her and I felt a familiar longing for her. She kept throwing me the “come fuck me eyes,” too. My roommate could feel the tension building up and excused himself from our presence, back to his room.
She got up from her seat and came over to me. She straddled me, her skirt hiking up past her hips, revealing black lacy underwear and a garter belt.
“So, why don’t we skip the bullshit and get right to why I’m here, huh,” she smiled and lowered her face to kiss me. I felt myself resist for only a second and then our lips were locked in a deep and passionate kiss. She gyrated her hips on my lap, and my cock swelled beneath her. My hands cupped her firm ass and I felt myself falling for her the way I had five years prior. She was a wild fucking woman who I had hated to let go of. My mind wandered to my sleeping girlfriend who I loved dearly. “She’s an adventurous woman,” I reminded myself, “i bet I can play this off as risky cheating, and then turn this into a threesome, I really think I can,” I thought to myself. I kissed her and she nibbled on my lips.
“We can’t do this out here, my other roommate will be home soon,” I said, “we should take this to my bedroom.”
She pushed down on my cock and said, “didn’t you mention your girlfriend was sleeping in there?”
“I sure did, so we’re gonna have to be quiet and sneaky,” my hands running up and down the sides of her tight and taut torso.
“You are so bad. Is this going to be like the time we cuckholded that shitty boyfriend I had?” My mind flashed back to a time I had visited her and we tied down this loser she was dating and made him watch as I fucked her every which way before blowing my load inside her.
“Not quite. Think of this as more getting-away-with-it style,” I responded. She smiled a sexy smile and grinded on my hard cock again. I stood up off the couch with her legs wrapped around my waste and her arms around my neck. I gently opened the door to my bedroom. It was dim, but not dark. My lady had hung some orange lights on a window for Halloween, creating a nice glow in the room. I gently laid her down on one side of the bed, and pulled her panties off. I could feel the heat radiating from her pussy on my face, and gave it a soft, silent kiss. My mustache was instantly soaked in her honey, and I could smell the familiar fragrance of her pussy on my face. I ached to be inside her. I crawled up to her face and we kissed while I reached a hand down and loosened my pants. She moved her feet to my hips and pulled my pants down, a trick she always blew me away with. I slowly pulled her dress down from her small breasts and sucked on her perky nipples. When she started to make noise, I kissed her to muffle the sounds. I reached down with one hand to play with her wet pussy, causing more muffled groans. She grabbed my dick and stroked it slowly, and then probed her wet slit with it. She grasped me by the butt and pulled me against her. My cock pushed against her wet lips, and then through. We both gasped in the thrilling moment, and just laid there staring in eachother’s eyes. My girlfriend stirred in her sleep and we held our breath. Then slowly I started thrusting in and out of her. She wrapped her legs around my hips, pulling me close to her. We moved together in a slow rhythm, mufflin our moans into eachother’s necks. Before I could stop, we were bucking against eachother. I felt her shivering beneath me and I covered her mouth with my hands, quieting her ecstatic shrieks. I felt her pussy gripping my cock, and her juices rushing forth out of her tight slit. My girlfriend stirred again and we froze. I could feel that I was already not far off from cumming, and her kegel muscles were contracting on my engorged cock. After a moment I began thrusting again. I could feel that pressure building up at the base of my cock as we bucked and fucked again. My girlfriend again stirred and we stopped, but it was too late. My cock throbbed and jerked and began filling her pussy up with an incredible load. I started to moan and she kissed me again to silence me, and then she came to the feeling of my dick throbbing and pumping her full of cum. We laid there silently in ecstasy and then I heard a wet, stirring sound beside us.
“That was really hot baby, who did you just cum inside?” My girlfriend asked, and I realized she was playing with her very wet pussy.
“Well, this is an old fling of mine, her name is Shawna,” i said, still shuddering. I felt my cock pump another squirt of cum into her when I said her name.
“Well move, I want a taste,” and she playfully pushed me off the bed, and moved her face between Shawna’s stockinged legs. I watched as she licked and sucked and kissed and nibbled on Shawna’s pussy. Shawna bucked and quaked and let out a loud moan as she came again. Amanda gave me a glazed and glossy smile, and crawled up to Lock her lips with Shawna’s. They kissed sloppily, our mixed sex juices smearing over both of their faces.
“She’s tasty and beautiful,” Amanda smiled at me, reaching down to play more with Shawna’s freshly creamed pussy, “Shawna,” she cooed, “i love making women cum harder than they ever have in their lives, have you ever squirted?” Amanda asked in an almost musical tone. Shawna could only gasp and shake her head no, “that’s terrible,” Amanda said, “I’m going to change that for you tonight,” and she kissed her deeply while quickening her diddling motions on Shawna’s clitoris. She did this for a couple minutes and then moved herself into the 69 position we love to watch the girls in oh so much. Amanda sucked and kissed and diddled her pussy while Shawna licked and probed her. The girls moaned and groaned and sighed in a duet. I felt my cock stiffening, and I was at half mast when Shawna cried out in another orgasm.
“Honey, I’m gonna need your cock to get her over the edge,” she practically sang to me. I climbed onto the bed and she took my growing member into her mouth, sucking and bobbing her head before grabbing it by the base and rubbing it over Shawna’s pussy, guiding me back into her. I fucked her slow and deep while Amanda continued to play with her clitoris. My fucking grew faster and I felt Shawna squeezing my cock with her well muscled pussy again. I heard a sucking popping noise as her mouth came unstuck from Amanda’s pussy and she cried out, and a gush of juice exploded from her pussy.
“There we go there we go there we goooooo!” Amanda cried out, and she let forth a small gush from her pussy that gently spashed over Shawna’s face. Shawna gasped and fought to catch her breath, her body writhing and convulsing uncontrollably, her pussy gripping and milking my throbbing member. Amanda turned her body around to kiss Shawna, her ass pressed against my stomach. She wriggled playfully and asked Shawna if she could have my cock for awhile. Shawna nodded, her eyes wide and blissful. I popped out of her and into my girlfriend. Amanda bucked back, fucking my dick with her own motions while she kissed and nibbled on Shawna’s lips, neck, and ears, her hands exploring Shawna’s tight frame. Amanda’s perfectly round ass bounced off my hips creating those lovely jiggles as she bounced off my body. Her pace quickened, her breathing shallowed, and suddenly her pussy let forth a torrential gush of cum while she cried out. Shawna cried out in surprise at the sheer volume of my girlfriends squirt. Amanda squeezed my dick out of her and she gasped “her turn again babe!”
I pushed back into my old fling and fucked her wildly now, her body splashing in Amanda’s cum. Being used to my girlfriend’s gushing orgasms, I had put a waterproof mattress cover on my bed. While this prevented the mattress from getting soaked, it caused puddles of pussy juice.
Shawna bucked back, her body lifting Amanda’s as well as she gyrated and fucked me fiercely. Amanda reached down and patted and slapped Shawna’s pussy, causing Shawna to cry out and her pussy explode in another set of gushing spasms. The girls giggled and gasped and kissed deeply, and then Amanda got up and moved to a dresser in the corner of the room. I picked Shawna up and turned her over and laid her face down on a dry part of the bed. I slid back into her in the prone bone position and started fucking her hard, causing her body to bounce on the mattress. She was crying out and moaning and she shouted about how much she missed fucking me. Amanda sat beside us and started squirting lube between Shawna’s buttcheeks.
“Shawna honey, are you the girl that got my man into ass fucking?” She asked. I smiled. Shawna again could only nod as she shuddered into another orgasm.
“I haven’t gotten my ass trained just yet, but I’m willing to bet he really misses fucking yours,” she again said almost musically and she grabbed me by the base of my cock and pulled me out of her pussy and pressed my engorged head against her lubed sphincter, gently pushing me into her. Shawna squealed and pushed back, her asshole swallowing my member. Ever since I had fucked her ass those years ago I had tried to train my new lovers for anal, but it never seemed to take. Shawna was like an anal artist, and her butthole squeezed and swallowed and released and stroked my cock in a way that I had never felt from any of my lovers. It was like a blowjob from her ass. I reveled in the feeling and slid my cock in and out in deep stroked. Amanda sat beside us, watching and rubbing her pussy into another orgasm. She sprayed Shawna’s ass with her squirt and I fucked her juices into Shawna’s tight little dirt box. Shawna cried out and had another shuddering orgasm. Amanda lifted her body and crawled under her, and stuck her favorite vibrating egg toy into Shawna’s pussy. I could feel the vibrations. I was fucking a vibrating ass. I started pounding harder and harder. Shawna cried out and let loose a major squirting orgasm as she quaked and quivered on Amanda’s body. Amanda cried out in glee, encouraging her to let it go. Then she looked at me, “cum in her ass babe! Let it go, fill her ass with the biggest load you ever let loose! Do it babe, do it for all of us,” and her voice was drowned out by a rushing in my ears, and I exploded in her ass, my cock practically pissing cum. Shawna cried out, cumming at the feeling, her ass squeezing my dick and seemingly pulling it in deeper. I collapsed, managing to catch myself so I didn’t hurt the girls beneath me. Amanda cooed and kissed Shawna. I felt like a dog that got stuck in its mate, I wasn’t sure I could get my dick out just yet. I felt it deflate and slowly removed it from Shawna’s tight ass. She rolled off Amanda, and I saw cum spill out of her browneye. The girls laid there, softly kissing eachother. Amanda whispered in Shawna’s ear, “did you like that babe?” She said softly. Shawna nodded and kissed Amanda deeply, “Good, we should do this again sometime!”
I laid down in the wettest part of the bed and we sandwiched Shawna, together we passed out in a tangled meat triangle. We would definitely need to do this again.
