He works out his gullible girlfriend’s best friend

[Please forgive the grammatical errors, my boyfriend told me this story while fucking me and I had to get it all written down while it was still in my head!]

Justin’s sweet naive girlfriend Dani was at work when he texted her saying,
“I can’t wait for you to get home cause I’m horny as hell and need to fuck you into a coma!”
Dani told him that she couldn’t wait either, but apologized, saying she was too busy at work to keep sexting him but would see her boyfriend soon. Justin was too horny to settle for that and decided to teach his gullible girlfriend a lesson in the process.

[Backstory] Justin loved his girlfriend more than anything, but his libido was far higher than Dani’s was.. so rather than pressure her into more than she was comfortable with, the considerate boyfriend usually turned to other women to get a release. Justin hardly felt like he was cheating since he always fucked the other women right in front of Dani.. it’s not his fault that she believed his BS excuses and was always so clueless and gullible.

[Back to the story]

The horny boyfriend found out that Samantha, his girlfriend’s 5’3 THICC assed brunette best friend, was single.. so he started texting her. (The two of them had slept together well before he started dating Dani, she was actually Samantha’s roommate back when he used to come over frequently to hookup.) They eventually started sexting a little and Justin decided he’d convince her to come over to “work out,” telling her it’s fine that she comes over and “of course” Dani won’t care. Samantha came over and the former fuck buddies started stretching for their workout.

He laid her down on her back and that he’s gonna stretch her legs. The sex deprived boyfriend had his girlfriend’s much hotter best friend spread her legs, he then ran his hands up her thighs to her ankles and helped her stretch by leaning into her. He could tell Samantha was getting excited because the middle of her tight workout shorts were getting wet. While he was stretching her, Justin acted like his hand slipped when he was getting up and rubbed it across Samantha’s pussy. She made a surprised face and laughed a little bit, thinking it was an accident, but also kinda hoping it wasn’t.
He told her to go ahead and bend over and then put her head down. Justin got behind his girlfriend’s obviously excited best friend to “stretch her back” and made it very obvious that he was hard when he leaned into her. Samantha started to moan a little bit and eventually he felt her thicc ass start to press back into him. He decided to lean into her harder, pressing his hard cock into her pussy. Dani’s somewhat-loyal but turned on best friend stopped him, saying it was going too far. Justin calmly reassured her,“seriously, it’s fine, Dani will never find out lol she’s too busy at work,” which was all the coaxing she needed to fuck her best friend’s boyfriend behind her back.
He ripped her shorts off and immediately saw that she was dripping wet down her thighs. Justin pulled his big throbbing cock out and slid it so easily inside Samantha’s dripping wet pussy.

“God damn” he said, “your pussy is so fucking wet. Danielle never gets this wet. She never feels this fucking good.” He slid his thick long cock deep into her tight wet pussy before slowly pulling out to the tip and repeated his thrusts again. “Well, I guess if she would fuck her boyfriend properly,” Samantha said, “you wouldn’t be fucking me right now so it’s her fault.” He picked her up off the floor and brought her behind the couch. Justin bend her over the back of the couch and started fucking the shit out of Samantha from behind.
“Fuck baby that ass looks so good while I’m slamming my cock into you. Danielle’s ass can’t come close, how have I not slipped into you and cheated until now? This feels so fucking good!”
Right around that time, Justin heard his girlfriend start to unlock the door, home early. Samantha panicked and started to push him off of her but the smug boyfriend said “No, wait. I have an idea.. just play along.” Dani came inside and Justin happily said, “Hi babe! Sam stopped by to work out with me. I’m helping her stretch out since we just got done”. His gullible girlfriend said, “Ok cool. Hey Sam!” Her best friend tried to say hi back but the sneaky boyfriend shoved his hard cock deep inside her pussy behind the couch and made her moan instead. Dani glanced back confused, saying “What? I didn’t hear you.” Justin simply responded, “Oh nothing babe, I’m just really stretching her out right now… getting deep into those muscles ya know”. His girlfriend laughed and said “ah, ok! haha! Well you two have fun. I’m gonna go change out of my work clothes.”

She walked away and Samantha finally pushed him off of her and said “what are you doing?!” He told her, “just trust me, she’s too dumb to realize what we’re doing. I NEED your wet pussy. Dani can never fuck me like you do”. Justin knew how much Samantha loved being the hotter of the two and always one upping her best friend. He said, “Here, watch this.” Taking Sam’s hand and pulling her to the bedroom while his girlfriend was in the bathroom.. and threw her on his girlfriend’s side of the bed. He ripped off the rest of the sexy friend’s clothes and climbed on top of her. She wrapped her legs around him as his big cock slide back inside her tight pussy, knowing it’d leave wet spots on his girlfriend’s side of the sheets.

Dani came out of the bathroom and Justin quickly pulled the blankets over the sneaky pair. He said, “oh hey baby. Samantha needed a softer surface to lay on for these last few stretches and there’s a draft in here.” His clueless girlfriend just nodded and walked to the closet to change. Smugly, Justin started thrusting into Samantha’s pussy again, without attempting to be quiet that time. “See, she has no fucking idea I’m balls deep in her best friend. She’s so fucking clueless. God damn your pussy feels so good. You’re seriously such a better fuck than Danielle,” he said as he slammed into his girlfriend’s way sexier friend’s tight pussy. While Dani was still in the closet, her best friend Samantha started really getting into it after Justin’s degrading dirty talk… clenching her pussy tightly around his cock.
He couldn’t help it and shot his load deep inside her as she came hard on his cock.

“It feels so much better cumming in your pussy than Dani’s ever could,” he tells her, knowing she loves hearing it. Justin advised Samantha to wait there, he’d get a shirt for her to use to clean herself off. To her shock, Justin started to walk naked into the walk in closet where Dani already was. He closed the door behind him, making his girlfriend turn around to look. She saw him standing there, rock hard, cock dripping with his and Samantha’s cum. Her boyfriend said, “Hey babe, can you hand me a shirt…I’m sweating like crazy… look how bad it’s dripping off of me! haha! All my clothes are drenched..” “Oh, yeah babe. I bet you worked hard huh?” she said while she grabbed him a shirt. “Oh…very hard,” Justin responded. “Actually you know what would be hot… if you licked the sweat off my cock real quick.” Dani immediately caved, loving her boyfriend’s dominant side. He pushed her into the corner and forced his cock down her throat. Grabbing the sides of her head, Justin thrusted his cock in and out until his girlfriend licked every bit of his dick clean.

When he finished, she said, “Jeez babe, your sweat is really salty, maybe you should get a water you seem dehydrated.” Having no idea she just licked up her best friends cum. Justin happily responded, “That’s a good idea. I’m gonna go get Sam and I a water.” He came out of the closet and she was already in the living room dressed and about to leave, worried that her best friend would be furious with her. Samantha nervously asked, “Did she find out??!” Justin just moved in close and passionately made out with his girlfriend’s best friend right in the middle of the living room before he laughed and responded, “Fuck no lol! That bitch is so dumb. I even made her clean your cum off my cock telling her it was my sweat and she just lapped it up like a fucking bitch in heat haha.” “Oh my god that’s insane! She’s an idiot for not knowing you fuck other girls…. so… wanna help me work out again tomorrow then?”.
