Caitlyn’s orgasm slowly waned, her pussy still contracting and leaking juices down her ass crack. “God that was incredible,” she gasped.
“Tell me about it,” Mandy laughed uneasily. “Did you just pee on me?” She asked in confusion.
“No, you made me squirt, just like Nathan does,” Caitlyn chuckled. “Now fuck me more please, fill me with your hot cum Mandy,” She pleaded.
Mandy quickly guided her cock back into Caitlyn’s, now swollen, gaping pussy, burying it. Mandy started thrusting hard and grunting loudly.
“That’s it, fill me with that hot load, let me fucking feel you cum,” Caitlyn moaned, urging Mandy on.
“Yes, yes, I can feel it, I’m getting close, fuck yes,” Mandy announced, her thrusts becoming more forceful.
“Do it, Mandy, cum inside me, cummm,” Caitlyn hissed.
“Ahhhhh fuck,” Mandy roared, her body tensing up, and thrusts slowing.
“Oh yes, there you go, fill me up. God, it feels so fucking hot,” Caitlyn moaned with a half laugh, looking down at Mandy’s cock cumming inside her.
I sat there, mesmerized by Mandy’s cock throbbing and spasming as she filled Caitlyn’s pussy with cum. I watched some of Mandy’s cum leak out around her cock, surprising me she had that much.
Mandy stumbled backward, her cock slipping out of Caitlyn’s gaping pussy, followed by a trickle of her cum. “Fuck, that was even better,” She said, still catching her breathing.
Caitlyn ran her hand over her slit. “Mmm, you stretched me open and filled me up with so much cum,” she moaned, scooping up some of the leaking cum and bringing it to her mouth, “Mmm.”
“Yeah, I did. I couldn’t help it,” Mandy chuckled, still catching her breath.
“Mmm, don’t worry about it,” Caitlyn said, lowering her legs. “Now, since you got to fuck me, I think Nathan should get to fuck you,” She continued.
Mandy looked at Caitlyn in horror, “w… wh… what? What do you mean?”
Caitlyn chuckled, “I think you know what I mean. You’re the one that started this whole thing, so apparently you wanted it to happen.”
“Hon… honestly, I… I did it just to watch you guys,” Mandy said nervously.
“Oh really?” Caitlyn asked.
“Yeah, I’ve listened to you guys have sex a couple of times, and I have wanted to watch you guys ever since,” Mandy replied.
“Well it’s kind of too late for that now,” Caitlyn chuckled.
“Yeah, I guess so,” Mandy laughed softly.
“Well, are you attracted to girls or boys?” Caitlyn asked bluntly.
“Honestly both,” Mandy said quickly.
“But yet you’ve never done anything with a guy before?” Caitlyn snorted.
“N… No, because no guys seem to want to with me,” Mandy said, looking down at the floor.
“Well, now’s your chance. Come on, let’s try it and see what you think of it,” Caitlyn said, grabbing Mandy’s hand and pulling her towards the couch.
“I… I guess so,” Mandy said nervously.
Caitlyn patted a spot next to her on the couch, “Come on, sit down and lay back.”
“What about lube?” I inquired, looking at my step-sister lying back.
“Umm, how about dipping into my pussy and using her cum,” Caitlyn smiled.
I cringed a little but realized that would probably work. I moved up on my knees between Caitlyn’s legs, as she laid back, smiling devilishly at me. I let out a deep breath, guiding my cock towards her still gaping slit.
“That’s it, baby, slide your cock in me,” Caitlyn moaned.
I pushed the head of my cock into her pussy, immediately feeling the warmth and wetness of Mandy’s cum inside of her. My cock easily slid into Caitlyn’s loosened pussy, Mandy’s cum enveloping my cock. “Damn she filled you up,” I groaned.
“Mmm hmm, it was amazing,” Caitlyn moaned.
I slowly began to withdraw my cock, looking down to see Mandy’s cum streaking down the shaft. I pulled back until just the head of my cock was inside of her, then quickly slammed back into her.
“Oh fuck yes, fuck me, baby, fuck my cum filled pussy,” Caitlyn growled.
I started fucking Caitlyn hard, enjoying the feeling of her extra wet, stretched hole. “So fucking good,” I groaned.
“Okay baby, that’s enough, it’s time to try fucking your sister,” Caitlyn said, pushing against my abdomen.
I withdrew from Caitlyn’s sloppy pussy, my cock glistening with their combined juices. Caitlyn helped Mandy to raise her legs so I had access to her ass as I moved over to her.
Mandy looked up at me with fear in her face, her eyes moving down to my glistening member, her breathing hastening. “Relax Mandy, it’ll make it easier,” My girlfriend said, looking at her.
I moved forward until my cock brushed up against Mandy’s ass. I grabbed the base of my cock, lined it up with Mandy’s rosebud, and started pushing against it.
“Yes baby, do it, mmm,” Caitlyn moaned, holding Mandy’s legs up.
I moved the head of my cock up and down Mandy’s hole, teasing it a bit, before applying steady pressure until it started to open up. I sucked in my breath, watching the head of my cock slowly disappear into my step-sister’s ass.
“Oh my God,” Mandy cried out, closing her eyes tight.
I slowly sank further into her ass, feeling her sphincter muscles contract and relax around my invading member. I stopped with about 3 inches of my cock in her ass, allowing her time to get used to it.
“Mmm. Yes, Mandy, look at that, your brother’s cock is inside of you,” Caitlyn cooed.
“Fuck it feels weird,” Mandy groaned, breathing heavily, looking down at my abdomen.
“Trust me, it gets better,” Caitlyn giggled, grabbing Mandy’s limp cock and tugging on it.
I started to push my hips forward, watching my cock slowly disappear into my step-sister’s bowels. “So fucking tight,” I growled, feeling her sphincter continue to squeeze my cock.
“Oh God, oh my God,” Mandy gasped softly, throwing her head back.
I pushed into Mandy’s ass until my cock was completely inside of her, holding myself there for a while. “Here we go,” I whispered under my breath, slowly moving my hips back, seeing Mandy’s anus clinging to my member.
“Oh yeah, fuck her baby, fuck your sister,” Caitlyn said excitedly, continuing to play with Mandy’s cock.
I pulled back, leaving an inch of my cock in Mandy’s ass, before slowly pushing back in. “Mmm yeah,” I groaned loudly, burying my cock in her bowels again.
Mandy lifted her head back up, looking at me with ecstasy. “I can’t believe you’re inside of me Nathan,” She gasped.
I smiled at her, slowly moving my hips back and forth, my cock slowly sawing in and out of her asshole. “It feels so good,” I groaned, moving a little faster.
“She’s definitely liking it, baby. She’s getting hard again,” Caitlyn lightly chuckled, jerking on Mandy’s growing cock, faster.
“Oh God, mmf,” Mandy hissed, her body beginning to tremble.
I moved faster with each inward thrust, feeling Mandy’s balls slap against my lower abdomen. I could feel her prostate, rubbing against the top of my cock, heightening my pleasure. “Fuck your hole feels so good, ” I cried out.
Caitlyn moved her hand up to Mandy’s chest, fondling her tits. “This is so hot watching you two fuck,” She hissed.
“It… It f… feels like… I… cou… could, m… m… my body is all tingly,” Mandy stumbled out, looking down at my hips moving back and forth.
I looked down, watching Mandy’s renewed erection bouncing as I fucked her harder, noticing precum oozing out of the tip. “Damn Mandy, you… your a… ass is… is going to make me cum soon,” I stuttered, feelings my balls pulling closer to my body.
“Yes baby, cum in her, cum in your sister,” Caitlyn urged, looking down at my cock sliding in and out.
“Oh my God, he… he’s… his pee… penis is getting bigger,” Mandy cried out.
Caitlyn grabbed Mandy’s cock again and started tugging on it hard. “Cum for me Mandy, cum while your brother cums in you,” She growled.
I pounded into my step-sister’s ass, feeling my orgasm growing. “Oh yes, oh yes,” I hissed, feeling Mandy’s prostate throbbing.
“Oh fuck,” Mandy cried out, cum flying out of her cock and splashing down onto her stomach.
The sight of Mandy ejaculating triggered my orgasm, the cum rushing up my cock, my cock throbbing hard, spilling my load into her bowels. “I’m cumming, I cumming,” I groaned, lost in pure ecstasy.
Mandy’s ass clamped down on my ejaculating cock, making it hard for me to move, while her cock spilled out more cum onto her stomach. “Ohhhhh my God,” Mandy groaned her orgasm waning.
My body shook and trembled while I filled her bowels with my cum. “Fuck me,” I gasped, collapsing on top of my step-sister, continuing to move my hips slowly, ensuring all of my cum was expelled.
“Now that was fucking hot,” Caitlyn exclaimed next to us.
report I lightly laughed, still trying to catch my breath and regain my strength. I felt Mandy’s cock between us, still lightly throbbing as it softened, and her cum sticking to my stomach.
I was finally able to push myself up, smiling at my step-sister, “Are you okay?”
“Mmm hmm,” Mandy nodded. “More than okay, that was amazing, but your cum inside me feels weird,” She continued.
“Better than having sex with me?” Caitlyn asked.
I slowly withdrew my softening cock from Mandy’s ass, watching her hole close, pushing out some of my cum. I looked down at my deflated cock, streaks of cum still on it.
“All of this was incredible, thank you guys so much,” Mandy finally said.
“Mmm, nice recovery,” Caitlyn giggled. “Maybe we can have fun like this again sometime,” She continued.
I looked at my girlfriend in shock, “Again?”
“Why not? You seemed to enjoy it, and so did Mandy, we have other things to try,” Caitlyn smiled.
“Yes, I want to, like doing it again very soon. Would you consider staying the night Caitlyn?” Mandy asked, smiling wide.
“I would love to,” Caitlyn answered quickly, looking at me.
I looked at the two of them in shock, realizing it could be a long weekend.
