"I slept with Phoebe... The night of the party where we danced together" She held her breath waiting for him to answer. After a long pause she expected the worse.
"I know that" he said back to her casually. Kat felt as though her heart had fallen through the floor.
"H...H...How D...Did you know... Did she tell you?" Nathan smiled trying to comfort her. Kat's face had gone white as a ghost from the shock. "I was only sleeping like two meters away from you, I got up to go the toilet when I came back I couldn't get back to sleep. A little while later I heard you moan. I just laid there not moving listening to you."
"How much did you hear?" She was getting worried until she realized he wasn't angry.
"Everything"
"How come to didn't tell me?"
"I knew you would be shy about it... I knew you would tell when me when you were ready to, seems I was right" Kat sat down on the bed next to him. He gave her a gentle and loving caress on her thigh. Kat forced a small smile, pulling the covers over her and laying down. They continued talking for most of the night. Mostly about their night together, all of her thoughts and feelings, telling Nathan everything that happened underneath the covers that he couldn't see. Later that night Phoebe sat in the hallway with her favorite vibrator between her legs, wondering why Kat and Nathan were particularly louder then usual tonight. It wasn't until she returned to her room to hear them at it again when she knew that this night was different to all the others.
The rest of the week passed quickly with Friday coming quickly. The whole week Kat and Nathan did not talk about her attraction to Phoebe and that night. Tonight they were hosting another party, the first since Phoebe had been staying with them.
The house filled quickly as friends and friends of friends filled the house. Hours later the house looked as though it wouldn't fit any more people, it seemed that word had spread about their last party and tonight it seemed was setting out to top it. The alcohol flowed freely; Kat had been on the dance floor for over 10 songs now. Nathan was at the sound system with CD's in his hand talking to someone she didn't recognize. Music most likely she assumed with confidence. She continued dancing; she hadn't seen Phoebe since that afternoon before the people began arriving. So when she saw her walk past the lounge chairs to her left she instantly became wet, she was wearing a dark green medieval dress trailing behind her and swaying as she walked. The back was tied with golden string from the top right down to just above her buttocks, spread far enough to show a lot of shin. She thought it was probably the alcohol but there was no mistaking the desire she was feeling for her.
She looked back over to Nathan to see him looking at her. Kat just smiled to herself and continued to dance, she loved being watched. Her sexual arousal in addition to his eyes upon her accentuated her dancing, and soon more and more people began to watch her. She closed her eyes drifted away to the sound of the double bass; she felt the muscles in her groin tighten as she squeezed them. The orgasm hit her hard almost making her collapse. When it had subsided a few seconds later she opened her eyes to see she was still being watched although they did not seem to notice what had just happened. She looked around then when the song finished she went to the kitchen to grab another beer and cool off.
It was three in the morning and people started to leave, the music was turned down and those that remained continued to party, socializing amongst each other. Kat was lying on her back between Phoebe's legs, resting her head between her large breasts her hair draped across here cleavage. Nathan was across from them on a bean bag with a beer in his hand trying to hide his erection as he could not stop thinking about the two girls in front of him. He watched them lying together, watched as Phoebe's hand ran up and down Kat's neck caressing her. In addition to Kat, Nathan and Phoebe there was also Jason and his Girl friend, Tim, Cassie and another couple Nathan did not know. It did not take long for the conversation to turn to sex and inevitably to Kat and Phoebe's performance at their last party.
Kat and Phoebe took the complements and the jokes with red faces looking at each other often. When talk proceeded on to the kiss they shared the girl in the couple they didn't recognized bought up that she hadn't seen it. With that Phoebe said "Well it looked a little something like this" and with an evil grin leaned down to kiss Kat. It lasted a few seconds as those around enjoyed the view. When Jason begged for more the Kat teased him by grabbed Phoebe's breasts, pinching the nipples and then pushed him away with her feet. "That's all you get, now behave." The group laughed as the conversation continued with talk about all things sex related.
An hour or so later only Kat, Phoebe, Nathan, Jason, and Cassie remained. Jason had obviously drank was too much and was blurting out all sorts of gibberish and sometimes very inappropriate comments. Cassie thought it past time to get him home and asked Nathan to help carry him to the car. After he saw them safely off he returned to find Kat and Phoebe where he left them. Nathan sat back down and took a deep breath trying to keep himself from laughing, although the girls could not. They all began to laugh "Well I don't think he is getting sex tonight" Nathan said laughing even harder. It took Nathan more then 15 minutes to realize that they were alone. He sat up on the edge of the lounge chair looking down on the two on them on the floor. "They were right you know that kiss was pretty hot."
"What was? This?" Phoebe taunted as she bit into Kat's neck this time. Kat sucked her bottom lip into her mouth and bit on it gently, closing her eyes in pleasure.
"Yeah... Arhh that" Nathan replied, his mouth dry. When Phoebe broke from the bite she did not expected Kat's lips to come crashing into hers. They kissed passionately for what seemed like an eternity. Kat was still between Phoebe's legs, leaning more on her left leg to make it easier to kiss her. She could feel phoebe starting to grind against her ribs gently at first and then faster and faster. Phoebe's hands looped under Kat's arms pulling apart the laces of her purple corset between her breasts. It only took her a few moments before Kat's soft breasts were exposed. She started to massage Kat's breasts in large handfuls and pinching her nipples softly.
They seemed to forget that Nathan was even there as they lost themselves. Phoebe's right hand had found it way under Kat's skirt gently probing her wet pussy through her underwear. They still had not stopped kissing until Kat's left hand found Phoebe's pussy also. She inserted two fingers as deep as she could into Phoebe's soft folds, causing her head to shoot back in a spasm of pleasure. It forced her to break from the kiss; Kat wasted no time though, biting into Phoebe's neck much harder then before. Phoebe moaned loudly; Nathan couldn't take anymore, his cock needed to be released from its prison. He unzipped his pants... taking his cock into his hands and gently stroked it. Kat looked over at him, she loved to watch him stoke himself, but she had no idea how much she liked him watching her fuck another girl.
Nathan was very nervous, he didn't know how they would react to him jacking off while watching them; however it all melted away when he looked into the eyes of the girls watching him. Kat had fantasized about this ever since that first night with Phoebe. Kat tore herself away from Nathan a moment to look at Phoebe, who was also watching Nathan masturbate. Kat could feel Phoebe's pussy tighten each time his stroke fell. Kat was surprised by how much she loved the fact that Phoebe was genuinely getting off watching her boyfriend. She couldn't help but wonder what it would be like to watch Nathan fuck her while she watched them. The thought excited her more then she could imagine. She finger fucked Phoebe harder and harder and in turn Phoebe fucked her even harder too.
Nathan was getting close now; both girls knew it and couldn't help but moan louder. Kat came first screaming as her pussy tightened around Phoebe's fingers, causing her to begin slamming her fingers into the roof of Phoebe's pussy setting her off also. Nathan felt the pain well up in the head of his cock as he watched the two girls cum together. Their moans and screams sent him over the edge as he lifted his shirt and felt the first stream of white hit his stomach. The two girls watched wave after wave of white, stream out in time with his strokes. The girls shut their eyes savoring the last moments of their orgasms together falling into each other arms. Nathan adored them both so much, he also fell back into his chair watching them together.
Nathan couldn't take his eyes of them, Phoebe was the first to open her eyes and sit up. As Kat sat up and opened her eyes she began to giggle, Phoebe rose to her feet and helped Kat of the floor, She smiled and said "I think we need a shower" Kat stepped around behind Phoebe and wrapped her arms around her waist. "I agree, so what do say babe, you wanna cum join us" Kat purred with a sexy grin. Nathan smiled taking off his shirt and letting his pants drop to the floor.
Both girls laughed on the way to the bathroom, Nathan followed silently smiling to himself. The girls were a few meters in front of him and reached the bathroom before him. When he entered the girls we already half undressed with the water running. He stood in the doorway a moment and watched the steam envelope their bodies. He watched as Phoebe opened the shower door placing her right arm into the cascade of water and adjusting the knobs. When the water reached the desired temperature she hopped into the shower with a delighted scream.
