Bob practically collapsed on the edge of the bed. He had had no idea why watching his girlfriend suck his friends dick had made him so horny. All he knew was that he had just came harder than ever before, and whether it was the lack of sex over the last few days or the way Emma seemed to love the dirty situation, it had made the entire fuck mesmorising.

But little did the boyfriend know that it was yet to be over, that he played a very risky game cumming so early.

He knew Emma hadn't cum yet, and she was in an incredible state of horniness and desire. He had made a mistake assuming that his loving girlfriend would not be tempted by the still hard, 10 inch cock of his roommate, now placed inside her mouth.

Getting up, Bob surveyed the erotic aftermath as he stood up from the bed, taking a few steps back. Emma was absolutely flushed, her face was red from where she had been sucking, her hair was a mess and her pussy was absolutely soaked by this point.

Emma didn't say anything, but instead gave an upset look, showing her lack of satisfaction. She had been SO close, why did Bob have to cum just then? If only he had held out just a little bit longer.

Emma felt anger rise in her as her orgasm began to fade away, despite how erotic the fuck had been just before, despite how naughty and cheeky she felt sucking her boyfriends roommates cock in front of him, and despite the fact that his dick, by far the biggest she's ever seen, was mere inches from her soft lips.

"Poor form, man." Frank joked to Bob. Tom didn't mean these words, things could not have gone better for him.

"Yeah, that was surprisingly hot." Bob joked in response, trying to give reason. But no matter the excuse, he didn't expect what Frank was about to say next.

"Well, I'm more than happy to finish her off for you." Frank said without a tone of joke in his voice.

Emma's heart skipped a beat at these words. Her pussy jolted with pleasure and she could have cum there at the words.

Here she was, lying after receiving the fucking of her, while her boyfriend and his roommate casually talked about sharing her around for sex.

She had never thought about sleeping with anyone else while she was with Bob, but the eroticism and kinkiness of this whole situation completely warped her mind.

She needed to cum, so... so badly after being used naughtily before, but she knew there was no way Bob would agree to that, though every fiber in her body was praying that he would.

"Ha, Frank man." Bob started nervously, as turned on he was by watching his girlfriend suck a cock while fucking her, this was something else. He fumbled for an excuse. "You don't have a rubber."

"I'll pull out." Frank smiled, now looking down at the gorgeous girlfriend, his cock pressed against her lips. "The slut looks like she could swallow a good load of cum."

"Oh fuck." Emma moaned softly, though still loud enough to be heard by Bob.

Frank knew just how hot this whole situation was for her. To get fucked by two guys at once, to be watched, to be talked to like a whore.

But the fact that her boyfriend was here was the biggest thing for her, the promiscuity and dirtiness of him watching her set her body on fire. He had her exactly where he wanted her.

"Or I could blow all over your girls face." Frank added, making sure he referred to her as Bob's girlfriend.

"I don't know man." Bob said nervously, not sure how to approach the subject.

He realised just how far the situation had gone, he was partially to blame for being so open with his girlfriend. After all, he had just let her suck his roommates dick, he couldn't blame him for trying to get in her.

"I think Emma needs to cum." Frank answered. He moved the head of his cock and pushed it against her lips, parting them as he thrusted a few inches of his hard dick into her mouth.

Bob was now a few feet away from the side of the bed. He nervously looked toward his girlfriend, her mouth being gently teased by the thick, hard end of Frank's dick.

He had made a mistake by teasing her this badly. He tried to tell himself this was just a one night thing, something that got out of hand, all the while he didn't speak.

Emma looked back, staring at her boyfriend as she so obediently sucked on the thick head of his roommates dick.

She was turned on beyond relief, having her boyfriend watch her as she sucked another guys cock, it was so naughty, and much more erotic than any public sex fantasy she had ever had.

As she stared she looked with such lust, such desire, as if silently trying to beg him to let her fuck his best friend.

After a moment of silence, Frank slid his cock out from the lips of the loving blonde girlfriend and moved toward the end of the bed. He wasn't going to be stopped now, he was dying to get inside this blonde stunner.

Emma looked between Frank, who was now getting onto the bed. She watched in anticipation and unbelievable lust as her boyfriends roommate parted her legs around his muscular frame, his entire body leaning over her.

She couldn't believe this was going to happen.

This was by far hotter than anything she could have imagined for the evening. She was about to get fucked by a much bigger cock while he boyfriend was just feet away, watching the whole thing. She turned her head, her face masked with ecstasy and excitement.

"You sure?" She mouthed to her boyfriend. She needed this so badly.

Bob watched on as his roommate leant his hands either side of his girlfriends heads. He watched as her slender, silky legs instinctively rose up and wrapped around his muscular frame, squeezing tightly and pulling him towards her.

He felt his cock harden slightly while he watched the scene unfold, anxious about it, but all the while begging for it to go ahead.

After a while, he gave a nod to Emma, he wasn't sure why he was getting so turned on at the sight of his girl soon to be fucked by his friend, but he decided to go with it.

This was just a one night thing, he told himself, one superb fuck that got a little kinky.

Emma gave her boyfriend a dirty smile, she needed this so, so badly. Her body shot up in anticipation as she felt the heavy, thick tip of Frank's cock press to her soaking pussy, it's end teasing her cunt and causing her to let out a moan.

She kept her eyes fixated on her boyfriend, watching his cock twitch with excitement as his roommate teased her with his thick cock.

She knew Bob was enjoying this, he was a little reluctant, but part of him felt the same way about the illicit fuck that she did.

She stared into her boyfriends eyes, biting her lip as she felt Frank's incredible, huge dick start to slide so pleasurably into her warm, tight pussy.

"Ooooohhhh FUCK!" Emma moaned loudly, spurring herself on.
