“Holy shit, holy fuck,” I gasped, my whole body trembling.

“You’re a natural,” Caitlyn exclaimed, watching my body shaking.

I felt the head of my cock push against her throat, lifting my head and seeing she was able to take 6″ of my cock. “Fucking hell, so good, so fucking good,” I groaned, watching her slowly lift her head, the cool air in the room hitting my escaping member.

Mandy pulled up until her lips were just barely on my glans, flicking her tongue against my slit. She moved her head back down quickly, and moved back up, sucking hard both ways.

“Fuck yes,” I hissed, putting my hand on the back of her head, urging her to take me in her throat.

“Choke on it Mandy, he loves that,” Caitlyn urged, her hand between her legs, frigging her pussy.

Mandy slammed her head down onto my lap, the head of my cock hitting her gag reflex, causing her to choke. I held her there for a bit, feeling her spit soaking my lap and balls, before relaxing the pressure on her head.

Mandy pulled completely off my cock, gasping for air, “holy shit.”

“It takes some getting used to,” Caitlyn giggled, leaning over my lap and engulfing my cock with her mouth.

“Fuck yes,” I hissed, watching my girlfriend take my cock into her mouth until she choked on it.

Caitlyn choked herself on my cock for a bit, before pulling back off, grabbing my cock with her hand, jerking it hard. “Are you getting close baby?” She asked, looking at me.

I nodded quickly, “Yes,” looking at her with desire.

“I have an idea,” Caitlyn snickered. She turned to Mandy, “I’m going to try making you both cum together.”

“How?” Mandy questioned.

“Come here,” Caitlyn said, reaching down and grabbing Mandy’s erection, tugging on it.

Mandy sprung up, letting Caitlyn pull her into position. Caitlyn pulled on Mandy’s cock, pulling my step-sister in between my spread legs until her cock was close to mine.

I watched my girlfriend push our cocks together, squeezing them with both of her hands. I felt Mandy’s thicker cock throb against mine, eliciting a groan from me.

“Now fuck my hands,” Caitlyn ordered, looking down at our cocks squeezed together.

Mandy started moving her hips, causing the underside of her shaft to rub against mine. I started moving my hips as well, enjoying the feeling of my step-sister’s cock rubbing against mine.

“God this is so hot, 2 hard cocks in my hands, nothing better,” Caitlyn cooed.

Mandy and I started moving faster together, both of us moaning louder and louder. I could feel the cum boiling up in my balls, the pressure building in my loins.

“Maybe this will help,” Caitlyn giggled, leaning over and putting her mouth over our cocks.

“Oh my God,” Mandy cried out, moving her hips even faster. “It’s going to shoot, I’m going to cum,” she cried out, her hips movements becoming erratic.

Caitlyn moved her head back, as I felt Mandy’s cock throb hard. I looked down as pearly white cum rocketed out of the tip, splashing down on my chest.

“Oh yes, that’s it, cum for me,” Caitlyn yelled, watching Mandy continue to expel cum.

Watching my step-sister cumming, triggered mine, feeling the cum rush up my cock, flying out and hitting my neck. “I’m fucking cumming,” I groaned, my cock throbbing each time more cum flew out, joining my step-sister’s on my chest and abdomen.

“Holy shit, look at all that cum,” Caitlyn exclaimed, continuing to jerk our cocks, milking everything out of them.

Mandy sat down on her heels, breathing heavily. “S… So much better than masturbating,” she gasped.

I laughed lightly, slowly coming back to earth. I looked down at my body, seeing the combination of mine and Mandy’s cum covering.

“That was fucking incredible,” Caitlyn exclaimed, releasing my deflating cock.

“If you say so,” I laughed breathlessly. “What about the mess on me?” I inquired.

“Hmm,” Caitlyn moaned, before leaning over and started sucking up the combined loads.

“God you’re naughty today,” I groaned, watching her continue to suck up our cum

“Mmm hmm, Caitlyn moaned, making sure she got it all off me. “So much cum, and so tasty,” she smiled.

I looked down at my spent cock, laying limply on my lower abdomen. “You missed some,” I said, pointing at some cum on the underside of my cock, figuring it was Mandy’s.

“So I did,” Caitlyn giggled, reaching down and scooping it up with her finger. She brought it up towards me, “it’s your sister’s, taste it.”

Before I could protest or stop her, she shoved her finger into my mouth, rubbing it against my tongue. I tasted it immediately, it was a little bitter, but it didn’t taste bad.

“Look at that, your first taste of somebody else’s cum,” Caitlyn giggled.

“Yeah because you made me,” I snarled.

“I know, just like I make you taste your own sometimes,” She smiled.

“Yes, yes,” I growled.

Caitlyn looked at Mandy, “So how was it?”

“Incredible,” Mandy said quickly.

“I agree 100%. Now it’s time to see if I can get you hard, so you can fuck me,” Caitlyn said, getting up from the couch.

Mandy looked up at my girlfriend with interest, “Okay.”

“Get up here on the couch, I’m going to do what I do to Nathan to get him to go again,” Caitlyn said, stepping back slightly.

Mandy moved up onto the couch, sitting down next to me, her limp cock significantly smaller now. She smiled at me, “Enjoying yourself now?”

I slowly nodded, watching Caitlyn get on her knees in front of Mandy. Caitlyn grabbed Mandy’s thighs and pulled her to the edge of the couch. She pushed Mandy’s legs up and against her chest.

“Keep them up there,” Caitlyn ordered, grabbing Mandy’s limp cock.

Mandy quickly nodded, grabbing the back of her legs and holding them up. She looked down at Caitlyn, “like this?”

“That’s perfect. Now, Nathan, you get to help me, play with her cock for me,” Caitlyn said sternly.

I leaned forward, taking Mandy’s soft cock in my hand, and started tugging on it. I looked up at my step-sister, her attention focused on Caitlyn, ignoring me.

Caitlyn leaned forward, moving her face between Mandy’s ass cheeks, sticking out her tongue, and flicking it against Mandy’s asshole. “What the fuck, oh my God,” Mandy gasped loudly.

I knew what Mandy was experiencing, because Caitlyn has given me analingus many times, and it drives me crazy. “Just wait, it gets even better,” I chuckled, jerking Mandy’s cock harder.

“Fuck,” Mandy hissed through gritted teeth, gyrating her hips against Caitlyn.

I watched Caitlyn spit on Mandy’s asshole, before trying to push her tongue into it. I felt Mandy’s cock starting to twitch in my hand, signaling what Caitlyn was doing, is working.

Caitlyn moved her head back slightly, putting her forefinger on Mandy’s rosebud, and started massaging it. “Mmm, look at her ass opens right up,” Caitlyn moaned, pushing her finger into Mandy’s ass.

“Holy shit, holy shit…” Mandy started repeating, her body shaking, and her hardening cock jumping in my hand.

I laughed to myself, deciding to heighten Mandy’s pleasure. I leaned over, wrapping my lips around her semi-hard member, and sucking hard.

“Fuckkkkk,” Mandy yelled, her body writhing below me.

“Mmm yes, get her cock hard for me, Nathan, then you can fuck her ass after she fucks me,” Caitlyn moaned, finger fucking Mandy’s ass.

“Mmm,” I moaned, feeling my cock growing as well. I bobbed my head up and down, Mandy’s cock fully hard and stretching my mouth.

Caitlyn worked a second finger into Mandy’s ass, trying to open it up. “I can’t wait to watch you fuck this hole,” she groaned.

“Wh… What’s happening to me?” Mandy yelled, her back arching high.

I pulled away from her cock, smiling at her, “Caitlyn’s massaging your prostate.”

“It feels weird, but so fucking good,” Mandy cooed, breathing heavily.

“She’s hard now,” I said, watching Caitlyn finger Mandy’s hole with three fingers now.

“Good, I think her ass is ready for you too,” Caitlyn smiled, withdrawing her fingers. “Time to change places Mandy,” she said, standing up.

Mandy got up from the couch, while Caitlyn took the spot where she had been. Caitlyn raised her legs, pulling them back to her chest, and holding them in place. “Now fuck me, Mandy, fuck my pussy with your fat cock,” She hissed, looking up at Mandy with desire.

Mandy moved over the top of Caitlyn, putting her left hand on the back of the couch, while holding her cock with her right hand. She lowered herself down until the head of her cock pushed against Caitlyn’s slit.

I quickly reached down and grabbed Mandy’s cock, lining it up with Caitlyn’s hole. “Go Mandy,” I said, holding her cock until it entered Caitlyn.

“Fuck yes,” Mandy moaned, slowly sinking into my girlfriend’s pussy.

“Oh my God, it’s stretching me open,” Caitlyn gasped, gritting her teeth.

Mandy fully sank her cock inside Caitlyn, holding herself there, “So tight, so wet, so fucking hot, oh my God.”

I moved to the floor, behind them, wanting to get a firsthand view of the action. I saw Caitlyn’s labia stretched tight around Mandy’s thickness, causing my cock to throb.

“Now fuck me Mandy, fuck your brother’s girlfriend,” Caitlyn hissed, grabbing Mandy’s hips.

I watched in awe, Mandy moving her hips back and Caitlyn’s pussy gripping her cock tightly. I grabbed my cock and started jerking it, watching my step-sister fuck my girlfriend hard and fast.

“Yes, fuck me, fuck me,” Caitlyn grunted, lifting herself into Mandy’s thrusts.

“This is so good, so fucking good,” Mandy groaned, fucking with reckless abandon.

My eyes were mesmerized by Mandy’s swinging ball sack, wondering how much cum they had left in them. I jerked my cock faster, knowing I didn’t want to cum yet, but I couldn’t stop myself.

“Fuck, your cock feels so good, I wish I had known about this a long time ago. Fuck you’re going to make cum, don’t you fucking stop,” Caitlyn yelled.

“Uh huh, uh huh,” Mandy grunted, not slowing her pace.

“Yes, make me cum, make me cum with your fat cock,” Caitlyn gasped, her body shaking.

“Oh fuck, I’m cumming, yes, I’m cumming, ahhhhh,” Caitlyn yelled, her whole body convulsing.

I watched Caitlyn’s pussy contract around Mandy’s cock and force it out, her pussy squirting against Mandy’s abdomen. My cock throbbed, watching Caitlyn’s orgasm consume her, her pussy squirting even more against Mandy, and soaking the floor below them.
