I[M] completed a sexual sweep of four sisters in five years [FFFF] [Part 1 of 4]

So I asked around and this seemed like an OK thing to do. This is the first of a four part series of four sisters, all of whom I've been friends with since I was in grade school. The family is a good friend of my family, but have had some falling out over the years. Distance has been the biggest factor.

The four sisters are Marisa (21,20), Kalli (34,34), Cassidy (30,25) and Hannah (20,20). The two numbers are ages. The first is what age they are now, the second is when I was having sexual relation(s) with them. I'm 22 now, so if you want to know my age, hopefully you're OK doing a little math.

I'll be telling the stories in past-present tense, as if you were over my shoulder watching it happen 5 years ago, 4 years ago or whatever. I'll also be telling them from oldest story to most recent. This is the story of Cassidy.

…

At this time I was going to high school with Cassidy's two younger sisters, Hannah and Marisa. We'd frequently be over at their house, four-five times a week. Often, I'd go over when no one was home or when it was just Cassidy or Kalli, whatever. We were all really close.

I was 17, always horny and an athlete. I was a runner, so I was in fit condition and figured to have a healthy sex drive. One afternoon in the summer, like 1,000 others, I went over to Cassidy's house to wait for Hannah and Marisa to get home from musical practice. After walking in, I thought I was alone. But after getting some water, I heard sobbing from upstairs. "Hello?" I shouted out. The sobbing stopped, and a door opened.

"Chase, is that you?" Cassidy replied. I told her it was and she said she was sorry and I could come up to her room. I was shocked, really. I had always found all the four sisters very attractive, but never have they invited me to their rooms before. You know how that is…

So I trotted up the stairs and opened the door. There was Cassidy, a 5-foot-8 blonde, in a sports bra and running shorts. The room was dark, shades closed, lights off. I remember the ceiling fan running for some reason.

"Sorry, sorry," she said again, still sobbing, fighting it back. "What's wrong?" I asked, innocently.

"I just found out Derek has been sleeping with someone else!" she told me as she let out more sobs. Cassidy was a third-year grad student at the local university. Derek was her boyfriend of four years, who she met at undergrad school.

I sat down next to her on the bed and she immediately fell into my lap. Nervous, nearly shaking and unsure what to do, I just stroked her hair. Everything I knew about sex was from TV or getting handjobs in the back of the movie theater as a 16 year old. I was a virgin, and she would have had to assume that.

I could feel her breathing, huffing against my crotch. Clueless, I tried to think about anything other than her doing that, because I felt a boner coming on. But nothing helped. She stopped crying but rested there. She leaned back up and looked at me.

"Chase, what's going on?" she said, in a soft voice. There was no hiding it. She felt it. She knew it was there. I stuttered, trying to get something out, ready to run out of the room. "No, it's OK," she said, placing her hand on the outside of my pants. "Is this because of me?" she asked, her face turning to a small grin. I bit my lip and nodded, unable to say anything.

"It's fine, it's good," she said, starting to grab and stroke it outside my pants. "Have you had sex, any kind of sex before?" she asked. Her vulnerability was through the roof, but like I said, I was a horny teenager, not sure what the hell to do. "No, just hand jobs and a blow job once or twice," I admittingly told her. "Lay back," she said, pushing me with one hand, undoing my pants with another.

I was hard. Hard as a diamond. And now, my cock fully exposed, she began stroking it, faster and faster. I just kept watching it, my heart racing. She never took her eyes off it. Probably for the best. It felt good, but it was dry. That was, until he leaned down, and pulled her hair to the side and submerged it into her mouth. Nearly cuming instantly, I gasped. She started slow, but it was warm. Her tongue was all over the place. I didn't know what to do still, so I laid there, moaning as she went to town.

Looking back, I know what she wanted. She wanted to be fucked out of her mind, and being the summer, no one was around. So she grabbed the first cock she saw. It didn't matter who it was, a cock was a cock to her at the time.

So pulled one last suck off and made that popping sound. She looked up at me, taking off her bra. Her boobs, fully exposed now. "Go ahead, grab them," she said smiling. I did as I was told. They were squishy, but still firm. Large. I had never seen anything like it in person. She pulled up my shirt as I sucked on her nipples. She began cradling my head between the two. That's when she popped the question.

"Would you want to have sex with me Chase?"

Unable to speak or move or do anything, all i did was grunt and nod my head. She leaned over to her nightstand and pulled out a condom. "Wear this. We have to be safe," she said. I put on the jimmy as she took off her shorts. She got on top of me again, and grabbed my cock to put it in.

She was so wet, it slid right in. The warm, juicy feeling of her pussy kept me hard. She put her hands on my chest and looked up at the ceiling. She began grinding me, harder and harder. I placed my hands right on her firm ass. I could feel every movement of her pussy against the tip of my cock.

"Chase, harder, harder, please!" she started to say. I don't think I moved much more, and I only lasted about a minute. She moved faster and faster and I told her "I'm going to cum, I'm going to cum" over and over, until I exploded into the little latex sack. I could feel it oozing against my shaft. She kept riding about 20 seconds more, then laid flat against me.

She started crying again. "I'm sorry, I'm so sorry," she said. "it's ok, I'm sorry it wasn't very long," I said back. That made her giggle.

Still unsure what to say now after my first sexual intercourse, I laid there and smelled her hair. It smelled like coconuts, I remember that. She pulled out and grabbed a towel and headed to the bathroom. I took that as my queue to make haste and get out.

As I was about to leave her room, I ran into her.

"We can't tell anyone about this, OK Chase? I could get into trouble." Honestly, I wanted to tell everyone. But I was way too scared of her. I agreed and headed back downstairs.

I didn't see her the rest of the summer. I'm not sure where she went, but she just wasn't around. I asked and every time they would say "oh she's just out and about," which I thought was strange.

To this day, we've never spoken about it. We've talked and remain "friends" pretty much by obligation. She's 30 now and married. Lucky bastard.

If you have further questions, or want some exclusive details, PM me and I'll help you out. Hopefully you look forward to her other three sisters. Next is the lovely Marisa.
