[MF] My girlfriend’s little sister’s best friend

So myself, my girlfriend and my two buddies used to live in a house together. Myself and my girlfriend, Sarah, used to share a big room with an en suite while my two buddies had their own separate rooms. It was originally just me and my two friends living in the house but because my girlfriend was always there anyway, she decided to ‘officially’ move in and contribute towards rent and bills.

Before she moved in, we’d always throw big parties for any occasion. Didn’t matter what the occasion was.

A few months after Sarah moved in, things were a. It tense between us as we were adjusting to our new living arrangements. We threw a Halloween party and Sarah invited her sisters to the party. I was dressed as a banana in pajamas, Sarah was wonder woman (looked hot).

The party was great. It got towards the end of the night and everybody had started to go home. Sarah and I had a fight over her smoking dope and she went to bed.

Left up was me, a couple of friends spaced out and my girlfriend’s little sisters friend called Amber.

Amber was dressed as little red riding hood. She was a bit on the plump side but had a great ass and D tits. She was dating some loser who treated her like shit and everybody thought she could do better.

I had changed out of my costume into sweat and pants. I walked into the kitchen and lent against the fridge, Amber was doing the dishes. I told her to relax and that we’ll do then tomorrow. She continued to do them though but kept chatting. I couldn’t stop staring at her cleavage. I loved big tits and Sarah only had size Bs. Amber asked me about Sarah and I’s fight. She said everybody heard it.

I brushed it off, said it was no big deal, I just didn’t like when she smoked dope. As I was taking, amber was drying her hands. She came right over to me and whispered in my ear “if I was with you and you didn’t want me to smoke dope, I wouldn’t… I’d never do anything to annoy you…”

We looked at each other for what felt like an hour but was only a minute. Here was my long term girlfriend’s little sisters best friend who was barely legal basically telling me she wanted me. She kissed me and I pulled away.

“Amber, Sarah would freak…”
“Sarah won’t find out…”

She dropped to her knees and pulled my dick out of my sweat pants.

“Fuck it’s so much bigger than Nick’s…” She said as she looked up at me. I hated the cunt, nick, she was with so loved it when she said that.

She wrapped her lips around it and started sucking my dick. She grabbed onto my ass to pull me closer to her face. I couldn’t help but worry about my friends who were still awake only a couple of doors away and my girlfriend who was in bed above us.. but when I looked down and saw little red riding hood deep throating my cock, I didn’t care. I grabbed her by the back of the head and face fucked her.

After a few mins she gasped for air and asked me to fuck her. I pushed her over and lay her back on the kitchen table, the same table Sarah and I would eat breakfast tomorrow. I lay her back on it and pulled her skirt up. She had little white panties on that we’re basically see through from her juices dripping out of her.

I pulled them to the side, lined my cock up against her pussy and asked “are you sure?”

She replied “ugh just fuck me!”

I slid into her. I reached up and pulled her costume down to release her massive tits. Fuck they were unbelievable. I sucked them as I slid in and out.

I asked her “am I better than nick?”, She told me to shut up and just fuck her but I needed to hear more. “What about your boyfriend who’s going to pick you up tonight? Are you going to let him fuck you later after I’ve had you?”

She played me at my own game and said “what about Sarah? Are you going upstairs to fuck her after fucking me?”

This sent me over the edge. I came so fucking hard in her. She didn’t cum, I didn’t care.

I pulled out of her, she pulled her panties to the side and smiled at me.

We chatted for a while and then nick picked her up.

I went upstairs and fucked Sarah the next morning.

Amber and I would do this every party we threw until eventually Sarah and I broke up and amber and I lost touch. Amber now has two kids with that guy nick.
