Tina moved over to the bed beside her best friend and put her hand around her naked shoulder. She felt like she should comfort Addie for some reason, like the loss of Addie’s virginity to her own brother would be difficult for her. Now, it didn’t seem like Addie was against it at all. In fact, she looked like she had a great time. It seemed like something Tina needed to do for her friend, since this had been her idea.
“How are you doing, Addie?” Tina asked as she looked over at her recovering boyfriend. She knew he could probably be ready to go again in a few minutes, and then it would be her turn to put on a show.
“Good! Really good!” Addie said with a smile. She rested her head against the side of Tina’s face. She could feel some of the heat coming off her friend and knew she was likely very turned on. That was good, she had hoped that going first would allay any fears Tina might have and back out. Addie really wanted to make sure she fixed the damage she’d done to Corey and Tina’s relationship.
“You don’t feel weird having just had sex with your brother?” Tina asked, a bit of surprise in her voice. She’d figured Addie may have had some regret after the fact. It was one thing to imagine doing something and another to live it afterwards.
“Honestly, no. I can’t think of anyone I’d rather have had my first time with than him. I love my brother, as most sisters do, but now we’ve shared something special. Something that goes beyond the usual displays of family love.”
“Wow, that’s actually beautiful,” Tina replied, her eyes nearly misting. “I didn’t think you knew how to even put a full sentence together,” Tina added to tease her friend and cut the emotions.
“I’m good too, by the way,” Corey added as he faced the two girls.
“Oh, please, you’re the luckiest person alive tonight. Two girls in one night?” Addie verbally poked at her brother before lightly punching him in the arm.
Tina joined in with her friend, “Seriously Corey, tsk tsk tsk,” as she jokingly wagged her finger at him.
“Hm, I didn’t think this through; I’m outnumbered,” Corey grumbled. He looked over at his sexy naked sister and his equally sexy underwear-clad girlfriend and wanted revenge. He quickly reached out and jumped on top of Addie, his hands reached her sides, and he started tickling. It was a dirty play, since he knew exactly where to get her laughing the quickest.
Addie started rolling around on the bed, her arms and legs flailing as she giggled and laughed. Her back curled as she tried to protect her vulnerable parts, but being naked gave little place to hide from his fingers. Corey did his best to hold her still so he could reap his vengeance upon her.
Addie pleaded for help from her friend, “Please ... hehehe ... Tina help! hehehe!”
Tina did her best to pounce on her naked boyfriend to aid Addie. She attacked his flanks, her fingers tickling his ribs to defend her friend. Hands slipped as bodies squirmed. Tina’s hand accidentally touched Corey’s growing cock, still damp from its excursion inside of Addie. As Addie struggled against her brother, her hands made contact with Tina’s soft breasts, still covered by her lacy red bra. Corey tried his best to block Tina’s tickles, but he couldn’t help but laugh, not only from the touching but also from the absurdity of the situation. It was like a wonderful dream that was actually happening at that very moment.
Addie couldn’t take much more, still tired from sex. She pulled her friend on top of her to use as a human shield. Tina hadn’t expected that and fell onto Addie, her breasts landing on her friend’s face. Corey seized the advantage and locked both girls together, focusing his attack now on Tina’s sides. His fingers lightly teased her ribs just below the sides of her bra and down towards her panties.
Having both girls underneath him and squirming made him aroused again. He let his fingers play over Tina’s body, moving up from her sides to cup her bra-covered tits which were still pinned on Addie’s face. He wanted to touch them and see her beautiful tits next to his sister’s smaller ones. He slid one of his hands over Tina’s back and skillfully unclasped it in seconds. The garment came loose and dropped off her shoulders onto Addie’s face.
“Oh God,” Tina moaned as he let her up so he could feel her free breasts. Addie could just watch as it played out inches from her face. She knew they were getting hot and wanted to help out. The tickling had ended, so Addie reached over and tugged at Tina’s panties, which fell onto the ground at her feet.
“I think you two need to get a room,” Addie said as she tried to give the two others some space.
“We have one,” Corey said with a grin. Tina finished her boyfriend’s sentence, “ ... yeah, yours.”
“Then let me get off the bed,” Addie said as she tried to free herself.
Corey let her up and out and focused on Tina as they climbed onto the bed together. Their lips met, and their tongues danced together. Their hands sought each other out as they embraced on Addie’s bed. Addie sat in her chair and watched them, hoping they would seal the deal together for the first time, at least as far as she knew.
Addie watched as Corey cupped Tina’s larger breasts and lowered his mouth to suck on them. Addie couldn’t help but feel a little jealous of her friend’s shapelier figure. She always wished she had tits that big instead of the little bumps she thought she had. She watched as her brother buried his face between the mammary flesh, his lips kissing as he moved between them. Addie knew that feeling well, and she could almost feel it herself. Her own pussy started to throb.
Corey dipped his fingers into Tina to see how wet she was, and he wasn’t surprised to find she was soaked. He had heard her play with herself while he was with Addie and knew she had enjoyed the show. He went to lower his head to lick her, but she shook her head no.
“I want it, Corey. I need it now!” she pleaded, her eyes twinkling with lust.
“Addie, could you pass me that condom?” Corey asked as he pointed to the one on the floor earlier.
Addie bent down and retrieved it, handing it to her brother. She was excited to actually watch her brother and friend have sex for the first time. She pulled her legs up onto the chair and spread them open as she slowly teases herself before the main show. Her pussy still leaked a little cum from Corey’s earlier activity.
Tina watched Corey rip open the package, as he had done several times before. She quivered in anticipation, her body ready for another good round with her handsome boyfriend. Things felt extra exciting this time, though, having witnessed Corey take his own sister, the tickling, and now being watched as they were about to have sex. Tina looked over at her friend on the chair; she was still naked and looked horny. Tina looked over Addie’s body, her blonde hair, cute face, small tits, and her legs that were pulled up onto the chair. This angle gave her a good view of Addie’s pussy, something that, until tonight, she hadn’t really looked at before. She could see the pink interior, clitoral hood, all the little bumps and flaps that led to her vaginal cavity. A white substance leaked out, a deposit from Corey earlier.
“Wait!” Tina cried out. Corey looked down at his girlfriend, surprised after he’d just finished rolling the condom on. Addie looked on nervously, afraid her friend was backing out at the last minute, but she couldn’t have been more wrong.
“What’s wrong?” Corey asked, concerned.
“Addie was right. I want to feel it inside me, too.”
Corey looked shocked. “Tina, what are you saying?”
“Take that thing off and give it to me like you did your sister. I want to feel you cum in me.”
Corey was in disbelief as he looked down at Tina’s face and saw she was serious. Overjoyed, he pulled his meat wrapper off, tossed it, and kissed Tina’s smiling face. His naked cock brushed up against her wet pussy. She reached between them and guided him to her entrance. Addie leaned forward to watch closely as Corey sank himself into Tina’s glistening pussy.
Tina moaned loudly as she felt Corey bottom out in her. As he started to thrust, Tina reacted to the incredible sensations that coursed through her body. She wasn’t sure why, but it felt different than when they’d done it before. It just felt more ... real, she thought to herself. She wanted him even deeper, to hit all the best spots that made her legs twitch. Her legs wrapped around his hips to pull him tighter against her as she met his thrusts with her own.
Addie couldn’t help but watch as her best friend was taken by her brother. She’d been worried about and jealous of this before she gave Corey Tina’s phone number. Right before her was the act playing out in her full view. She watched as Corey’s cock would disappear into the pink flesh of Tina’s pussy before extracting and plunging back in. Her eyes were transfixed on that point of contact. She couldn’t look away, not that she wanted to. She actually found the whole thing an incredible turn-on.
Absent-mindedly, her fingers searched out her own pussy and dove in. Her face was blank with lust as she fingered her still dripping sex as she watched the other two engage in the devil’s tango. She expected to enjoy looking at her brother, she always did, but she was just as turned on by the sight of Tina. Addie’s ears could hear her friend’s guttural moans and groans, the squishing sound coming from the tight friction where they connected. She could even smell the hot musky scent of sex in the air, knowing for once it wasn’t from her.
Corey was lost in the act of love with his sexy girlfriend, and he barely noticed his sister gawking at them at all. He thrust hard in her like he knew she liked, but this time it was free from the constraints of a latex sausage casing. Now he actually had a fair point of comparison between the two girls, especially having just fucked Addie a short time earlier. The differences between the two were subtle but still there. Addie’s pussy felt a little smoother inside, wet and tight, but with less massaging flesh. Tina felt a little tighter, and her insides gripped and released him like it was milking the cum out of him. No matter what, he loved both girls and was happy that he could enjoy them openly at that moment.
The two lovers kissed, wet mouths smacking together as their bodies collided on Addie’s bed. Corey could tell that Tina was getting close; she was mewing and moaning louder than usual. He, too, was getting there and tried his best to hold off till his girlfriend got closer. He wanted them to cum together. He kissed down to her tits and licked around her nipples to help draw her closer.
“Oh Corey!” she cried out, frantically grinding herself on his cock. The squeal in her voice told Corey she was about there. He thrust long, hard strokes into her, pulling almost all the way out and slamming as deep as he could into her.
“I love you, Tina,” Corey groaned as he neared the precipice.
“I love you, too,” she said, pulling his head to hers for a quick kiss. “Now cum for me. Let me feel it!”
Addie watched as Corey pulled everything but his cockhead out and slammed deep into Tina. He did this twice. On the third time, he stayed in as deep as he could. She could see the muscles in his legs strain from the tension as his butt clenched tightly. A tiny amount of white liquid seeped from the thin space between the two sex organs. Addie’s fingers flew over her own clitoris in rapid circles, bringing her to her own orgasm.
“Well, how was that?” Corey asked Tina as he brushed away some hair from her face.
“That was ... wow! Yeah, we’re doing that again.” Tina smiled up at him, untangling her legs from around his back.
Corey pulled his tired cock from Tina, an ooze of white cum leaked out from the now vacated space. Tina looked down between her legs and attempted to see the mess, but she saw Addie looking at her with a smile.
“What? Why are you so happy?” Tina asked, teasing her friend.
Addie handed Tina her phone and sat down beside her. “You did it, you actually did it. How did it feel?”
Tina pointed the camera of the phone at her pussy to get a better look at herself, then responded, “It was great! I wish I had done that earlier. What about you? How do you feel now?”
“Happy; warm and happy that I got to share this with my best friend.”
“You don’t find it weird that we both just had sex with the same guy? Your brother, to be precise?”
“No, I think it was supposed to be this way. I love him and I love you, too.”
Tina put down her phone and hugged her friend. They were both still naked, which felt a little strange as their naked breasts touched, but the feelings were there. “I love you, too, you big freak.”
Both girls broke out into giggles, and Corey watched happily from the side. So far, this was what he had hoped would happen. The animosity and distrust had vanished; there was no jealousy or doubt, just the two friends sharing a moment together. He also couldn’t help but enjoy the sight of them touching and hugging each other naked, but he was currently too spent to try to make something of that at the moment.
“Are you two hungry? Should we order some food or something?” Corey asked, as all that exertion had built up an appetite.
“Yeah, let’s get some food. Pizza?” Addie suggested, and the other two agreed.
Corey placed an order on his phone from their usual place once everyone agreed on what to get. Like most groups, the larger the group, the more difficult it is to agree on pizza toppings. There was some back-and-forth about onions or no onions, peppers or not, and whether they should get anything else. Breadsticks and drinks were chosen, and it was time to wait for the delivery.
Tina reached down to pick up her panties from the floor, wanting to get something on. Addie had a different idea, though. “What if we don’t?”
“What if we don’t do what?” Tina asked, confused.
“Why don’t we stay like this for the rest of the night?” Addie said, stretching out and showing off her sexy naked body.
“You want to stay naked all night? I didn’t know you were a wannabe nudist,” replied Tina, somewhat intrigued by the idea.
“Look, if I weren’t here, you’d probably stay naked with Corey tonight, right? And if Corey were my boyfriend, we’d do the same. Why not all three of us? We’ve already seen everything. Not much of a surprise now.”
Corey liked the idea but felt like he’d missed something. “I’m all for this, but ... I think the pizza guy might enjoy it a little too much.”
Addie turned to Corey, a devious look on her face. “I guess we’ll have to do something about that.”
The doorbell rang thirty minutes later, and an embarrassed Corey went to answer it. Addie and Tina watched from around the corner as he opened the door to collect the food. The delivery guy, the same one Addie had dealt with a few weeks ago, had a surprised expression when Corey appeared wearing a flowery dress.
