Being My Sister's Boyfriend

She looked down at this, knowing that wasn't going to be enough lube, and so my sister spat on him, spread her saliva with her hand, then enveloped him with her boobs once again. This time she started thrusting her chest, and he responded in kind with his hips, fucking her cleavage, the wet squishing sounds of their rubbing flesh filling the room.

They seemed to have just begun to lose steam due to Alana's saliva lubricant drying up when the guy began spewing greater amounts of pre-cum; enough to keep them both lubed and fucking. Alana would switch between fucking him hard by holding her great boobs together, and just letting her breasts slide back and forth over him loosely, teasing but no less erotic. Often the guy would take control by pushing her tits together himself, but his favorite move seemed to be grabbing the bottom of her hanging tits and holding them, feeling their weight and the hard nipples pressing in his palms.

"Hey, man," he said, looking to me for a brief instant before putting his eyes back on the wonderful sight of his cock tit-fucking my sister. "If you want to touch her, or, you know, do things..."

It was music to my ears, because I was about to lose my mind just watching all of this and my dick felt like it was going to pop. But I was certain Alana would consider that to be crossing the line, fine as it may now be. Still, I looked to her for approval, but she responded with a non-answer, drawing her boobs off of the guy's dick and quickly taking him into her mouth. He bucked his hips at the unexpected pleasure, and Alana half-choked as his big head likely poked the back of her throat, but that only motivated her to suck him harder and faster. She actually tried taking him into her throat on a few subsequent thrusts, and though I don't think she ever made it, I could tell the guy appreciated her attempts.

As I watched, the guy's invitation for me to touch Alana, or more, nagged at my thoughts. He wasn't just okay with it--he'd suggested it, so apparently the two on one scenario excited him. And I was definitely up for playing with my sister no matter what was going on around me. All I was unsure about was whether Alana would accept it. I decided to test the waters.

I reached beneath her, moving slow so she could see me and have time to stop me if she wanted to, and gently took one of her soft, bobbing breasts in my hand. No sooner had my fingers grasped her there when she swung her hand back, placed it over mine, and squeezed my hand hard against her. Our collective fist clenched her breast, pushing it close to her chest, and the adrenaline shooting through me at that moment almost triggered an instant orgasm. I stiffened, closed my eyes and tried to will the cum back.

"Oh man," the guy said, seeing my face. "He's going to cum! Your guy is gonna cum! If you want to take care of that," he said to Alana, "I'm cool with it."

I didn't even know the guy's name, he had come here to fuck my sister, the very girl I'd been lusting after for months, and yet at that moment I wanted so much to shake his hand and tell him thanks. Now aware of my situation and apparently not appalled by it--driven hot by it, actually--my sister pulled the stranger's dick out of her mouth, turned to me and wrapped her lips around my throbbing cock head while jerking my shaft rapidly with her hand. She did this for ten seconds, twenty. I wasn't going to cum. My bewilderment over this guy's acceptance of my presence had staved off my cumming, but I was still on edge. Realizing this, Alana sunk my cock deeper into her mouth and began bobbing on me; my sister was actually sucking my cock. I fucking exploded.

She moaned loudly as a massive, boiling load of cum filled her mouth. Jerking me with her lips and her hand, I shouted and thrashed and bucked into her face as I emptied what felt like half my bodyweight of sperm onto my sister's swirling tongue and on down her throat. I could hear her gulping madly. And then there was something else. A sniffle. I looked at her face more closely and saw tears flooding in her eyes and streaming down her cheeks.

I thought, 'oh no', but as soon as I saw this, Alana jumped up, taking her lips from my cock directly to my mouth and kissed me deeply. My cum not only coated her lips, tongue, and the entire inside of her mouth, but there was still some loose sperm in there that she hadn't made the time to swallow yet, and so I very clearly tasted myself on her, and yet I had never been so aroused by a kiss. With her lips and tongue, my sister gave herself to me fully, hugging me with her arms and clawing at me with her fingers, though I couldn't help but be distracted by her tears.

But it was explained when she broke the kiss for a quick breath. In a desperate, whispered voice, she sobbed. "I've wanted this so much, Gavin!"

And then she cried openly, even as she moved back to kissing me hard and deep, making me taste the remnants of the seed I'd just fed her before stealing it back with her tongue. She embraced me as though she might never see me again; as if she never intended to let me go. I was so overwhelmed with what she had just revealed to me that I didn't even notice her raise her hips; but I did notice, and with great, unparalleled pleasure, when she lowered her wet pussy onto my cum-coated, still hard-as-steel cock.

On top and demanding control, Alana rode me with expert precision, kissing me and stroking my face all the while. I hugged her back, rubbing her naked back to soothe her as her crying turned back into grunts of absolute pleasure. When she came, she didn't go into an all out frenzy like she had when the guy had eaten her out. Instead, she just melted into me, fucking and gripping me hard, grinding against me, holding her breath until she almost passed out, and yelling out excitedly for a full minute once she found the air.

We kept kissing and fucking long after her orgasm, our pace gradually slowing, though no less pleasurable. It was awesome and magical. I had honestly even forgotten about the guy laying naked beside us until Alana broke our kiss and turned to him.

"I'm sorry," she said. "But I just--"

"No, no," the guy waved her off. "I get it. That was actually really hot. You two are an awesome couple. I've never seen two people more into each other."

I still couldn't believe this guy. His laid back acceptance and approval made him seem like the second coming of Owen Wilson. I could tell my sister was just as surprised, and I felt that we both thought he deserved to be rewarded with what he had come for. Now that I knew how my sister felt about me, it was somehow as easy as ever to let her go to another guy. I helped her slip off of me.

"What should I do to him, sweet baby?" Alana asked in her sexiest voice. "Or what should I let him do to me?"

"I think you should finish his blow job," I said, which was honestly something I wanted to see. "And I think you should let him fuck your face...and then let him cum on it." A quick look to the guy told me that I had read his mind. Then, to her: "Does that sound okay?"

"Only if he fucks me good and cums a lot," Alana replied just before giving his half-erect penis a long, wet lick.

The guy was hard again instantly, and Alana had him all lubed up with her saliva and had a good stroke going not long after. She bobbed on him fast and deep, and soon he was bucking his hips against her face. I couldn't help but notice that she wasn't taking him all the way, though, likely because she would need to take that big cock head of his into her throat to do so.

Reading my mind, Alana pulled off him, pre-cum and spit leaving stringy trails from her lips to his cock. She was panting from her efforts as she spoke. "Help me deep throat him. Push my head."

The guy and I exchanged surprised glances, but even as we did I was moving into position beside her. I was about to grab her head when a better thought occurred to me, and I moved again, getting behind her. Though her blow job had made me cum, the subsequent fucking had started my engines all over again, and this seemed to be the perfect opportunity for me to concentrate my urges. Alana didn't protest as I entered her sopping cunt from behind, steadying myself with one hand on her ass while I grabbed her long, blonde hair at the back of her head with my other hand.

And then, slowly, I began to push her head down and pull it up again, guiding her to face fuck the guy's cock. She controlled most of these movements, and I was just hanging on for the ride, except for when she went down, which was when she needed my help to push her deep, forcing the fat cock head into her throat. With each of these strokes, we tried going a little deeper, thereby staying down a little longer, and all the guy could do was moan and groan from our efforts. Meanwhile, I was having a blast fucking my sister from behind. Though our careful movements with the deep-throating restricted how wild I could go on her, my sister's pussy was second to none.

Soon we had a good rhythm going, and Alana was taking the guy down her throat with each stroke. It eventually became so easy for her that she didn't need my help anymore, and so I concentrated on fucking her, both hands on her perfect ass and pulling her against me, driving myself in to the hilt with every thrust. The sex seemed to spur her on, and she throated him faster and faster, moaning as she did, until finally she took him as far possible and held him there, not breathing, clenching his heavy cock with her throat muscles.

"Cumming!" the guy called out. "Oh shit, I'm cumming!"

We all moved into action immediately, because we all knew the plan. Alana's desperate cries of "My face! Do it on my face!" only emphasized the importance for us to succeed. I pulled Alana back and on top of me, then slid out to get alongside her so that my dick was still in her, but I was holding her from the side. She lifted her thigh to allow me to fit there, and I hugged it, still fucking her, as the guy jumped on top. He straddled Alana's face, reaching it just in time. His cum squirted a thick, unbroken line of white from her chin, across her lips, over her nose and even past her eye to the middle of her forehead. The next blast spilled into her open, hungry mouth, splashing off her tongue. Further spurts showered her chin and cheeks, coloring her with sperm so white it seemed to glow in the dim bedroom glow.

Seeing her take the facial so excitedly, along with how she clenched my dick with her cunt, caused me to reach orgasm as the guy was finishing with his. He rubbed his fat, softening dick into the mess he'd just made on Alana's face as I began grunting and pumping, humping her leg and then shooting a spine-tingling load of jizz deep into my sister's body. Her pussy tightened as I filled her, as if she was eating it up like some greedy animal.

I kept thrusting into her well after I'd spent my load, but she kept herself busy by sucking the guy's dick clean, and getting him hard again in mere seconds. Once fully erect again, he forcefully but not harmfully shoved his dick in my sister's cum-covered face, stroking himself against her cheeks, forehead, nose and lips while she licked and kissed at him. He ground his balls into her nose and she licked them, her tongue reaching so far that she teased his perineum.

That was the trigger for this guy, and suddenly he was moving down, shoving his cock into her pussy just seconds after I had finally pulled out. No sooner had he entered her did the guy shoot his second load, which triggered my sister's third major orgasm. I shuffled out of the way as the two of them fucked through their climaxes, grunting and roaring, swearing and begging.

Though I was well spent, I couldn't help but jerk my softening dick as I watched my sister get fucked; her long, smooth legs wrapped around him, her big breasts rolling against her chest, the nipples hard and proud.

When we had all caught our breath, the guy seemed to have lost his understanding touch, because he didn't get that I expected him to leave now. It had been fun sharing my sister with him, but he'd gotten what he came for, and now I was looking forward to some alone time with Alana, if not to play, than to at least talk about the future. But the guy was making no effort to leave. He slumped into her bed, no doubt satisfied, thanking both of us for a night he said he'd never forget. I had just started thinking of things to say to get him moving when he spoke up for me.

"I guess I should get going."

My heart was lifting, but then I saw Alana shaking her head.

"No, tonight is your night. I'm not done with you yet," she said, curling up next to him and slowly stroking his soft penis. His cum still glistened on her face when she looked up at me.

"That was the plan, right baby?" she asked. "You were going to watch me fuck him, then leave us alone for the rest of the night, right?"

I wanted to crawl in a hole and die. Was she changing herr mind about us again?

"Go home tonight," she told me politely. "I need to suck some more cum out of this guy," she grinned, already moving her head back down toward his slowly hardening dick. "And I need that tongue back in me. How about a sixty-nine?" She was no longer asking me. She was asking him.

I couldn't believe it. She had just confessed how much she wanted me, and now she was throwing me away. As if that wasn't enough, she told me to go home. I was home! And to keep with her story, I'd have to leave the house and pretend to go somewhere. It was the middle of the fucking night, and I was naked! What was I supposed to do?

Not finding the words to voice my dismay, I moved to leave the bedroom, deciding to just open the back door and close it, making it sound like I had left when I was really just going to sneak into my own room. I was already dreading having to hear the sounds that would no doubt make their way from down here to where I would be sleeping.

"Name's Owen," the guy said as I neared the door, and while I did catch the irony, I didn't feel like laughing. I didn't give him my name, either.

"I don't mind if he stays," Owen told my sister, who avoided looking at me by burying her face his testicles. "He is your boyfriend, after all."

Right, I thought. And we just broke up.

But then, a light brightened at the end of the tunnel.

"Yeah," she said between slurps on his testicles. "But he can have me to himself anytime."

That statement didn't just give me hope--it gave me a hard-on, as well as the ability to jerk off from the potent sounds of sex I heard all night while I lay in my bed upstairs, fantasizing about all the things I could do with her "anytime".
