[MF] Seduced at a Party in front of my Girlfriend, (Part 2)

Part 1 is in the comments.

I drove Mara home in silence. The excitement of the encounter still racing through my head, but fading into the guilt I was feeling.
I had cheated on Alison, and I enjoyed it.

When I pulled up to Mara’s house, I still hadn’t said a word. She didn’t get out of the car right away. I couldn’t bring myself to look at her, but she leaned in and rubbed my crotch. My member responded slightly, once again rebelling against my better instincts.

She kissed me on the cheek and whispered, “Thanks. You were amazing.” Then she got out.

I made up with Alison and wrestled with whether or not to tell her, but I eventually decided against it. School was done so I would never have to see Mara again. Alison was a good girlfriend and I didn’t want to hurt her. It was best if we just put it behind us.

A month after graduation, we were invited to a house party hosted by a bunch of friends. I wasn’t that into it, but Alison really wanted to go, so I tagged along. When we arrived, the party was already pretty crowded. After we walked in Alison found a friend and started mingling. I told her I would go get us some drinks. As I approached the punch bowl, I saw Mara.

Fuck.

She was in the corner talking to some friends. She looked dress to kill in a short low cut black dress that showed off her magnificent tits. I couldn’t help but stare. She caught me looking.

Please don’t come over, I thought. Last thing I wanted was to be caught with Mara while Alison was around. But Mara only smiled and winked, then went back to talking to her friends.

I relaxed a bit. She must have gotten what she wanted. As long as she left me an Alison alone for the rest of the night, everything would be fine.

The party went on. I caught up with some of my mates and we played cards over a few beers. Mara came into the room a few times, but never approached or even looked my direction. I actually relaxed and started to enjoy myself. The time just flew by and I realized it was after midnight. I decided to check on Alison.
I walked around the whole first floor but couldn’t find her. I started to get worried and asked around. Finally, I found one of her friends who lived at the house. She said Alison had a few too many and had crashed on her bed.

I went upstairs to see if she was well enough to go home. I tried a couple rooms before I found the right one. She was splayed out face first on the bed, completely passed out. I walked over and touched her gently. She didn’t react. I decided to let her sleep it off. Maybe she’d wake up in an hour or so.

But then, the light from the hallway vanished as the door closed. I turned around, and there was Mara.

She stood in front of the door, smiling like I was a prey caught in her trap. I tensed and hoped Alison wouldn’t wake up now. Mara walked slowly toward me.

“Mara, you shouldn’t be here,” was all I could think of to say. Her smile turned into pout. One of those mocking confident pouts that women do when they know they’re in control. “Oh, you want me to leave?”

She was so close to me now. I could feel the warmth of her body. I could already feel blood rushing to my slowly hardening dick. But I resisted as long as I could.

“Yes, you should leave, before Alison wakes up.”

She smiled and leaned against me. I felt her breasts against my chest.

“Maybe she should.” She held there for a few seconds. Half of me wanted to grab her and kiss, the other half was barely holding that urge in check.

But she pulled away and walked past me to look at Allison.

“Maybe I should tell her your cock is mine now.”

She started to reach for Allison. I grabbed her arm and pulled her back. But I think that’s what she was waiting for because she fell back into me. She rubbed her perfect ass against my cock, which hardened in rebellion.

“Don’t!” I said, trying to be forceful, but it sounded hollow to my ears. She arched her body back into me. Her hand reached down and started rubbing my bulge, as she turned her head to my ear.

“Don’t you want to fuck me?” she said.

Her ass twerked against my dick.

“No,” was all I managed, but my mouth said one thing and my body another. My skin tingled at her contact.My hands involuntarily moved up her body and clenched her tits. She moaned.

“Her pace quickened as she jerked me off with her ass. Then her fingers reached down and found the top button of my pants. I felt it pop open.

I found myself lost in the sensation. My body wanted her, despite all reason not to.

“Fuck me,” she whispered, “Fuck me in front of her.”

I remembered Alison and felt my anger rise. This fucking girl was trying to ruin me! I grabbed her by the shoulders and violently pushed her away from me and into the wall. I held pinned her in place. Part me wanted to hurt her more. But then, I looked at her face.

She wasn’t afraid or shocked. She looked at me with lust. She wanted this. She wanted me. She suddenly kissed me hungrily, despite being pinned. I was so surprised I loosened my grip. She responded by pushing me back, hard. I lost my balance and fell on my back, knocking the wind out of me. She tried to climb on top of me, but I had come to my senses. We wrestled for a bit, but I was stronger and managed to flip her over on her back. I held her arms apart and pinned her body with mine. She stopped struggling.

I thought she had calmed down, but then I realized the position we were in and she did too. Our pelvises were on top of each other. She wrapped her legs around me and gently rubbed her pussy against my dick. I could feel the warmth through my pants. My dick responded to her touch. Without meaning too, my own hips started thrusting to meet hers, even though I held her down. We kept dry humping, and grunting softly, my face inches from hers.

After a minute or two, she stopped me.

“I want your cum.”

I froze at those words. With my hesitation, she reached down and unzipped my pants. She pulled them down and freed my cock from its confines. Then she looked in my eyes as she guided me into her pussy. Fuck, did she ever wear underwear? My dick pressed her lips, and following instinct, I pushed myself in the rest of the way. She moaned slightly and smiled with satisfaction as I went balls deep. Her pussy was so wet. I remember how great it felt before and realized I missed it.

I couldn’t take it anymore. I started fucking her immediately, giving her what she wanted. She moaned softly and let me go. After a few minutes, she spun us around. I was on my back again and she straddled me immediately. Part of my senses returned and I tried to get up, but she kissed me with such animal ferocity. I lost all ability to think, but she didn’t need me to. She sucked my lips like they were her last meal.

As she settled on me, I saw her glance over at the bed, and then smile.

Fuck! Allison!

I looked over. she was still asleep. I could feel my panic mounting. I was inside Mara and Alison was right there. Mara held up her finger in a shhh motion, then she pulled her dress over herself. It slid off her so easily. She wasn’t wearing a bra and her teardrop tits lay bare in front of me. She started slowly thrusting. My body felt waves of pleasure. She pulled my face up into a gentle kiss and then I buried my face in her tits, kissing and sucking her nipples. She kept humping as she let me play. I could feel my pleasure building. She quickened her pace and held me against her, keeping me in me in place like I was a prisoner. I let out a few soft groans.

Before long I felt my orgasm starting to build. She was still going strong, but now a few moans escaped her lips, and mine. I grew more conscious of the noises she was making and forced one of my hands free to cover her mouth.

She bit down, hard. I grunted in pain and pulled my hand away. She smiled coyly, pushed me down on my back, and locked her lips with mine, as if trying to subdue me. Then she abruptly stopped, got up, and remounted me reverse cowgirl. She gave me a perfect view of her ass and she aggressively rode me. She started moaning again, not holding back. I could tell she was close, but I was closer. She was going so fast, I felt the pressure quickly build.

Without warning, I blew my load inside of her.

But she didn’t even slow down. If fact, she went faster and faster. Soon after she moaned louder and I felt her come.
She sat on my for a few moments, then stood up. I followed and we both started getting dressed again.

Allison still hadn’t stirred. With her dress back on, Mara kissed me and I didn’t resist.

“Thanks. Until next time,” she whispered and walked out the door. I looked back at Alison and then followed.

I asked Alison’s friend if it was okay if she stayed the night. She said yes. I went home, thinking about the amazing sex I had just had. I felt bad, but not as much as before.

I met up with Alison for lunch the next day. She looked a little hung over but was alright. When I asked her if she slept okay, she said, “Oh, it was so awkward. I woke up in the middle of the night, and there were two people having sex right on the floor right next me. I stayed quiet until they left. I mean, who does that? ”
“I don’t know,” I said quietly.
