I met Ellen at college. We had the same photography class. Our teacher told us to pair up with the person next to us. We were both kinda loners and sat at the back separately but we were the closest ones to each other. That's when we first became friends. A few months passed and we developed feelings for each other. Shortly after that I asked her to be my girlfriend and she said yes! We always used to fool around in my car but she asked if we could go to my place. That's when she found out I was in a bad living situation. I had been living out of my car the past few weeks because my parents kicked me out. I didn't want to intrude and ask to go to her house. I didn't want to put her in a situation where she felt like she had to help me.
"If my little sister's girlfriend can live with us, so can you... I'll talk to my mom." She told me as we cuddled in the back seat of my car.
A few days later I got a text from Ellen telling me she told her mom about my situation and she wants to meet me. Ellen told me her mom had a long talk with Sarah, her sister's girlfriend, before she moved in too. I was a bit worried about what she wanted to talk about. The next day I went to Ellen's house and met Ellen's 37 year old mom Maria and her 18 year old younger sister Emily and Emily's 18 year old girlfriend Sarah. Maria wanted to get to know me more so she asked if we could take a walk outside. It was a general conversation about my home life and school.
"Honey, you seem like a good boy, but this house is not a regular house, sometimes we walk around naked and sometimes you'll hear us bonding sexually as a family." Maria said to me.
I didn't really know what to think about that statement so I nodded and said "I promise to respect your family customs" At this point I was just happy that I had a real roof over my head.
"It makes me very happy to hear you say that," Maria said smiling. "I have no issue with you moving in with us as soon as you like! Of course you will be staying with Ellen. Her bed is a bit small but I'm sure you can make do and we will sort it out later."
I went to my parents house to grab the rest of my things and brought them to Ellen's house. Later on after unpacking, Ellen and I took a bath together, then had dinner in her room in just towels. I was in heaven compared to what I had been living through for weeks. It was nice to be welcomed by a family that barely knew me.
A few days passed and I started noticing that walking around the house with minimal clothing was something very normal. I tried to actively avoid being in the same room with anyone other than Ellen. My eyes did wander sometimes and I didn't want Ellen to be mad at me for looking. I asked Ellen about her family walking around topless and almost naked.
"Just be respectful of those who are naked, and if you are comfortable I don't mind you walking around naked either" Ellen told me. "It's just something we have always done, Mom wants us all to feel comfortable together."
A week has passed. I woke up Saturday morning horny, fully erect. I tried to wake up Ellen for a quickie but she was tired and wanted to sleep a little more. In my horny frustration, without thinking I walked to the kitchen naked and still had a boner. When I get there I see Emily in a loosely tied robe. I panicked and instantly covered my dick.
"You want coffee?" she said as she giggled and looked at my hands covering my dick.
"Yes please." I said nervously.
"Go sit on the couch, I'll bring it over. And by the way you've got a beautiful penis no need to hide it." She said.
Her saying that made me grow harder. I went into the living room and sat on the couch. She brought over coffee and while sitting down she untied and opened her robe. It's like she wanted me to see her petite exposed body.
"You're still hard," She said pointing at my erection, almost poking it. "Where's Ellen?" Emily asked.
"She's tired and wants to sleep more." I told her.
"Me and mom can take care of you if Ellen can't, I hope you know what I mean... in fact it's been a while since I've had a dick inside me so if you want we can have a quickie right here!" Emily said.
"Isn't that cheating?" I asked. This was making no sense to me.
"No! My girlfriend Sarah has slept with Ellen and My mother. That's what we do, we share." Emily said.
"If this is one of your household customs your mother was talking about. I accept" I said nervously.
Emily took her robe off, fully revealing her milky white, smooth skin. She is 5' 2", quite skinny and has perky B cup boobs. Her nipples were hard as rocks pointing out at me. she got on her knees and started licking my cock. I looked down in bewilderment. She stood up and knelt down on the couch, one knee on each side of me. She pushed her tiny boobs into my face and slowly moved herself down onto my erection. She had a tight bald pussy. She rode me for like 2-3 minutes.
"Do you want to stop? I'm about to cum." I told her.
Instead she went faster and I couldn't hold it any more. I came inside her, she kept going as I was cuming. As she slowed down she leaned forward resting her head beside mine, breathing heavily. It felt weird, I just got fucked my girlfriends sister. She got up, dripping cum.
"I have to go and take care of Sarah now since she's probably going to wake up soon. But don't feel weird about telling Ellen, she'll be fine." she told me as she walked away.
Embarrassed and confused, I went to our room and woke Ellen up and confessed. She hugged me, standing at only 4' 11" her face was right into my chest.
"I was going to tell you, but didn't know the right time. Emily's Girlfriend Sarah and I have had sex a couple of times." Ellen said. I got a little jealous but Emily and I had just fucked so I guess scores were even?!
"I'm super horny now, please fuck me" She said
