It had been a month since Kate had hooked up with Justin at a Halloween party. She was the same old Kate when she talked to me, like nothing had ever happened. And she was right about no one knowing her or me at the party; getting fucked by Justin had been the perfect crime. But still, she felt guilty. She hadn't meant to cheat on me, only got caught up in the moment. We were a great couple and she wanted to forget the incident had ever taken place.

After the incident, Kate was hornier than ever. She constantly wanted to FaceTime with me and play with her vibrator while I would stroke my cock. She would let out soft moans with her feet in the air as the vibrator pressed hard against her clit. Her tight frame and smooth skin made it near impossible to last while watching her. I would cum within minutes of jacking off as she looked at me with a pouty face and played with her perky breasts.

Nearly every night, she would Snapchat me sexy photos of herself in lingerie or naked. Coming out of the shower or working out in the gym. I would get an instant erection every time I saw her perfectly round ass in a thong or her tiny waist that you could nearly wrap your hands around.

One night Kate texted me and asked if I wanted to FaceTime. All of her roommates were out at the bar for the night and she had the place to herself. I said yes and called her immediately. The call answered and there was Kate wearing a lacy black bra and panties. She had red lipstick on and her dark, thick hair fell across her face perfectly. My cock instantly swelled with blood. She pulled out her vibrator and I pulled out my cock.

After a few minutes of masturbating together, I couldn't last any longer and came into some kleenex. Kate was upset as she was just starting to build up to an orgasm and was turned on watching me stroke my cock. Just then, I got a call from work and had to leave our FaceTime. I apologized and suggested she watch some porn to finish the job.

Kate was disappointed and let out a sigh but then a voice from her doorway said something. It was David, her roommate, smirking while telling her he could finish the job if she wanted.

David was one of Kate's friends that she met in first year. Now Kate, David and three other friends lived in a house together, just off-campus. Kate quickly pulled up her sheets to cover herself. She asked what the hell he was doing back so early while hiding her vibrator out of sight.

He told her that he didn't feel like going out anymore and had decided to come back early instead. The rest of the roommates had gone to a club and were out for the night. He walked over to Kate and sat on the bed beside her. Kate could see the definition in his arms and chest through his tight white t-shirt. She was still extremely horny from the call.

"I know you can hear me having sex through the wall," David said. "Which means I also know that you can hear the girls moaning when I have sex with them."

He was right. David brought home girls all the time. He was a charming, smart guy with good muscles and a nice smile. Women gravitated to him naturally and he always capitalized. A few times a week, Kate would hear the intense moaning of some girl David was fucking in the room over. The girls always seem to cum over and over again and Kate couldn't help but think they were just trying to act like porn stars.

"I can't help but notice I didn't hear you through the wall much of the summer, though," he said to her.

"Well, that's just because I don't fake scream like the drunk bar girls you bring home," she replied.

"I heard Justin made you scream," he snarked.

Kate's face went beaming red and a wave of nervousness hit her. Up until this point, she thought no one had known about her and Justin and that she could just forget about it.

"Where did you hear that?" she snapped.

"Justin and I are old football teammates. He filled me in on your little Halloween adventure."

"That was a total mistake and no one is supposed to know about that," she replied to him.

"Just like no one has to know about this." He leaned in and pulled down her covers, exposing her bra and panties. His hand slid under her bra and he began to run his tongue slowly in circles around her nipple. In the moment, Kate realized just how much nipple play turned her on and she sank into her spot more, letting her guard down.

Suddenly David picked her up and tossed her onto her back on the bed. He pulled her lacy black thong to the side and began licking gently on her young, sweet pussy. Kate stuttered to get a word out from the pleasure, eventually ushering out for more. He pushed his tongue into her hole and sucked her clit while she writhed with joy.

Then David stood up, told her it was his turn, and unzipped his pants. Kate turned onto all fours and crawled closer. David pulled down his underwear to reveal his thick cock throbbing; it was so hard. His cock towered over mine in both thickness and length. Kate was shocked when she first saw it.

He told her to open wide and placed his cock in her mouth. She gagged as it hit the back of her throat, forcing her mouth wider than ever before. Prior to this, Kate thought she was great at deep throating; now she realized she was only great at deep throating my cock.

Satisfied with his cock being sucked, David flipped Kate onto her back and ripped down her panties. He stood in front of her with his hard cock glistening in pre-cum and spit. David grabbed his cock and guided it to Kate's pussy, slowly inserting the head and shaft. She grimaced as he went deeper and deeper but he ensured her it was only a few more inches and kept going.

Within a minute, Kate had relaxed around David's cock and he began deeply fucking her. His cock hit spots inside of her she never knew existed. What started as quiet squeaks became louder moans until David's balls were slapping Kate and she was screaming out that she was cumming. David laughed as Kate squirmed on his cock and convulsed in orgasm.

When she finished he flipped her into doggy and said he hoped she was ready for another one. At that point, I finished my work call and began FaceTiming Kate again. She, however, didn't notice the call coming through as at the same exact moment David's cock was sliding into her from behind. Her eyes closed as she realized a second orgasm was soon approaching. David grabbed her waist and fucked her hard, ensuring the whole length of his cock penetrated deep inside her. As Kate began to scream out, she was cumming again. David fucked her more vigorously before turning her around, putting her to her knees, and shooting a huge, sticky load over her face.

Kate was shocked. David gave no warning to a facial and she hated cum. "What the fuck, David," she said as she struggled to open her eyes and find something to wash her face.

"What? Most girls love it, and you look hot with my cum all over your face."

She couldn't help but blush, which was hard to see under the cum. David handed her a towel and told her he'd see her tomorrow before going back to his own room. Kate wiped the cum off her face before checking her phone and seeing I had called her. 'Shit,' she thought as she quickly FaceTimed me back.

When I picked up, I thought she looked a little different. Her red lipstick looked a little smeared. I asked what was on her cheek and she chuckled before saying just lotion she must have missed and rubbed it into her face. We talked a moment before she said she was tired and wanted to go to sleep.

Something seemed off about the call, but I couldn't quite put it together. Kate lay in bed thinking about the now two times she had cheated on me. Worst of all, the sex with David had been great. She knew she would have to work harder to suppress her urges going forward, but somehow she knew things would only get worse from here.
