The Summer I fucked my GF’s 18-year-old cousin – PART 2 [MF], [cheating], [anal]

I was surprised by the amount of attention [part 1](https://www.reddit.com/r/sexstories/comments/go44ek/the_summer_i_fucked_my_gfs_18yearold_cousin/) of the story picked up. I apologize for taking so long to write these out, I currently work countless hours in front of a screen and I avoid screen time whenever possible. This story will be a bit shorter, there was a lot that happened that summer so I will focus on the main parts.

The next morning, I woke up feeling so horny. I wanted to sneak into Maria’s room and “play” with her but I was just fantasizing. My gf was still asleep so I went to the bathroom to rub one out. After my mind was clear, I realized that I had to make sure this stayed a secret. I knew that is my GF found out about Maria, that would cause a lot of problems for me and their family.

I went downstairs to watch some tv and eat a bowl of cereal. As I am eating on the couch, I hear someone walking down the steps, I knew it was Maria due to the sound of her light steps. She leans over behind me and gives me a hug which surprised me (I almost poured my cereal over). I told her to stop with a serious look on my face. She looked back like she did something bad.

“You cannot be too close to me whenever you want. Trust me, I would love to hold you right now and probably do some other things but we need to set up some boundaries” I said

“Sorry!” she responded”

“It’s okay, but you need to careful. He is a list of things that you need to remember to keep this quiet. You must keep your distance when we are not alone. Under no circumstances do you text me about anything relating to our secret. Lastly, you must not tell anyone about our secret, not any of your friends, not write about it anywhere, etc.”

She nodded and agreed to my rules. I gave her a little kiss (already breaking my rules) just so she can feel a bit better. I felt like I was being a little too strict when I gave her the rules, but I had to.

The next several days, my GF never left the house, and if she did, she left with me or Maria. I did have a mild panic when they were alone, what if Maria confesses or is my GF found out. I was trying to stay stealthy as best as I can, but Maria and I would sneak in a kiss here or there or I would grab or spank her ass. Sometimes she would grope me, and it kinda turned into a game. We would touch each other when possible. I know it was extremely risky, but I really wanted to feel her, touch her, taste her holes again.

Things got interesting one night, it was the evening, and we were all watching a movie, we all brought blankets and sat on the same couch with Maria in the middle. Our blankets overlapped and we either had our legs up on the couch. Our AC was on blast so it was pretty chilly in the house. As the movie progressed, I did do anything other than rubbing my foot on Maria’s thigh. I move around pretending that I needed to get comfortable on my corner but I wanted to move my arm closer to Maria. I slowly started reaching down the small of her back and then slipped my hand into her shorts. I left my hand there without moving it. I just wanted to enjoy grabbing her ass. About halfway into the movie, she moves a bit towards my GF which basically left Maria’s ass towards me. I took advantage and slowly pressed my fingers between her ass cheeks and onto her asshole. Slowly but firmly I started pressing two of my fingers in. Because it was an awkward position, I think I was only able to go in an inch, I slowly started playing with her ass as best as I could. Maria kept a straight face the whole time and my GF was switching between being on her phone and watching the movie. I eventually stopped because I knew this was way too risky.

The movie ends and I basically had a hard on the whole time just fantasizing fucking Maria. My GF finally gets up and goes to the bathroom and right away, Maria jumps on me and gives me a deep kiss. I push her away and say “not now!”

“Sorry, I feel so horny right now”, Maria says (in Spanish).

“Me too!” I said with excitement in my voice.

Next thing I hear is my GF, she yells out if anyone needs to use the bathroom because she was going to shower. Maria and I said no and when we heard the bathroom door closed, Maria started making out. We were both flustered, the way we kissed and had our hands on each other’s bodies was intense. I stopped and ran to my office real quick. I left a bottle of lube in there and brought it back to the living room.

“Pull your shorts down,” I said in a dominating tone

“You sure? What if we get caught?” Maria responded

I grabbed her from the back of her neck softly yet firmly. She moaned when I did that. I pulled her shorts and panties down and I got to see that beautiful ass that has been on my mind. I added some lube on my dick that was already throbbing for some action. I slowly pressed the head against her asshole and she let out a small moan.

“I need you to cover your mouth with either the pillow or the blanket,” I said while slowly pressing my dick in her ass.

Thanks to the lube my dick slid in a lot faster from the previous time. I am normally the gentle type when it came to anal, but I was so sexually frustrated and I knew we didn’t have much time. I started thrusting a fast pace, Maria whimpered and moaned on the pillow. I pulled out real quick and spread her ass open. Her asshole was pink and swollen, seeing that just turned me on so much more. I jammed my dick back in and started moving faster. Maria started moving as well to my rhythm. Finally, I cummed in her ass without hesitation. As I pulled out, I saw some cum spill out and we quickly pulled our shorts on. I sprayed the living room with some fabreez to get the sex smell out of the air.

“I am sorry if I was a little too rough,” I said in a guilty tone

“It’s okay, I really enjoyed it, it felt better than last time,” she said.

After she said that, I got a little excited. It made me think that she liked getting fucked hard. My GF finally leaves the bathroom and Maria goes in to shower. I followed up right afterward and that was the end of the night.

The next several weeks were the same, we would touch each other as a game. We either had oral or anal sex at once or twice a week, but I really wanted to finally feel her pussy. On top of that, she was finally going to leave off to college. I talked to her about it but she was unsure about losing her vaginal virginity. One day she teased me and wore a skirt with no panties on, I was extra touchy on that day. We did not have much alone time so I spent a lot of time fucking my GF. I knew Maria did not like that.

I think it was either the last week or two before she left. We started slowing things down. I had to mentally separate myself from her and she understood somewhat. It also seemed that she was developing feelings and I expressed with her many times that this is only for the sex. One night, Maria’s boyfriend comes over again and they spent a while in her room. I didn’t think much of it, I knew that I had to cut ties and I also wanted to focus on my GF. Maria’s BF finally leaves later that night and I was wondering if they had sex or fooled around. I didn’t follow up and the night ended.

The next day, my GF left early in the morning, she had to go to a regional meeting for work so I knew she would be gone all day until the evening. I walk out of my bedroom and I saw Maria with her bedroom door open, it looked like she was pre-packing. I walked up to her to chat.

“Hey, how is it going? I can’t believe you are leaving already.” I said

“I don’t want to pack last minute so I will pack little by little. she said

I realized that today would probably be one of the last times we would be alone together but I also did not want to push anything. But I didn’t want to bring it up directly.

“How was your time with your boyfriend?” I said with a smile on my face.

“it was good, I finally let him put it in,” she said with a smile as well.

I felt a sudden urge of jealousy which was so odd.

“Did you lose your virginity?!” I said with a jealous tone in my voice.

“No, we had anal, but I made him use a condom. It kinda felt weird and I also didn’t enjoy it. He didn’t really know what he was doing honestly.” She said

“What exactly happened?” I said laughingly

“I basically had to tell him everything on what he had to do but he also became a bit suspicious and said that I am cheating on him. Not sure if he was joking or being serious,” she said

“Well, want to spend today with someone experienced?” I said jokingly

she looked at me with a straight face and said “You have to prove how much you want it”

Without hesitation, I grabbed her and kissed her passionately. I really missed her and I was also probably developing some feelings too but at the time I was trying to not think about it. She stops me and tells me that she needs to shower first. I go to my bedroom and wait in bed as I spend some time on reddit through my phone. Finally, she comes into my bedroom wearing a short red towel. She spent a lot of time in the sun this summer and her tan skin with that towel on made her look so appealing.

“You still have prove how much you want me,” she said

“What do I need to do?” I said, while also getting excited

I have never seen her be so dominant, and it just turned me on so much. She finally drops her towel and I noticed that she completely shaved her pussy. Not sure why I never truly paid attention, but she had an amazing naked body. She was truly model material.

“Close your eyes and don’t move,” she said.

I was expecting her to give me a blowjob or something but next thing I noticed, she had her ass on my face.

“If you want any of my holes, you need to kiss them the same way you kiss my lips” she said

Right away I started with her pussy, her juices were already flowing. She started grinding her hips on my face. After a short while, she moves her ass up and spreads them, and my tongue goes directly on her asshole. She was truly riding my face as I licked her pussy and ass back to back. After what seemed to be a while, I flipped her over onto the bed and I go into eating her pussy out with two fingers in her pussy and 2 in her ass. Within minutes she starts to cum and moans, this was the loudest she’s ever been during her climax.

“What’s next?” thinking that we were going to switch to anal sex.

“I want you to have my pussy,” she said as she is catching her breath.

I was surprised but also excited. Without hesitation or even thinking about a condom, I got up and kissed her, and I inserted myself slowly. This was probably the most passionate moment I have ever had by then. She let out a small moan and I started to pick up a slow pace while slowly making out with her. We stayed in missionary for a bit and I kept checking up on her to make sure she was doing fine. She asked if she can get on top and I rolled us around. This was what surprised me. She took charge very fast. She started riding me like she was experienced. I tried so hard not to cum, I stopped her a couple of times from moving.

Finally, after a bit, we switched to doggy style. I knew I was going to finish soon, so I started thrusting hard and fucking her pussy hard and I slipped my thumb into her ass too. She started to bite the blanket and she finally starts orgasming. I thrusted a couple more times until I let my load out.

“Fuck! we didn’t use a condom” She said

I panicked too until I told her that I would get her plan B. She seemed relaxed again but yet somehow we were both turned on, we just started making out.

Within seconds, I was ready for round 2. We went at it again, but it felt like we were making love instead of fucking. It was mostly missionary and heavy kissing. I know it may seem boring but it felt perfect. We spent about 2 hours like that. We took a break around noon. We decided to eat something real quick and it was kind of hot walking around the house naked. We started eating and talking

“How are you feeling?” I said

“I’m fine, I really enjoyed it” she responded.

I was a bit relieved that she said that. I wanted to make sure that we were comfortable the whole time, even though she was so demanding in the beginning.

“So what are you going to do after you leave for sex?” I said

“Maybe I can visit during holidays or maybe I will let someone else fuck my holes. Its only sex right? That’s what you always say” She responded

I felt a bit jealous but didn’t dwell on it. Instead, I told her to stand up and I picked her up and took her to the couch. We started to have sex again. Her pussy was still wet from the mixture of her juices and my cum. I fucked her on the couch with her legs on the side until I finally cummed again. As exhausted as I was, watching her naked in front of me with my dick in her turned me on so much. I know I didn’t share this before, but Maria was way hotter than my GF. Fucking this 18-year-old with a rocking body was intense.

We went back upstairs to my bedroom and we began to make out again. This time I was grabbing her ass and pressing my fingers into her ass. I grabbed the lube that was on the nightstand and added some to my fingers and I started rubbing the lube onto her asshole. I slid two fingers in slowly and she would moan and kiss me heavily and I slid in deeper. I pulled my fingers out and this time I tried with 3 fingers, then 4 fingers. My 4 fingers were basically knuckle deep and Maria just kept moaning and kissing me.

Maris gets on top of me and slides my dick into her pussy and she starts to ride me. I had one hand on her breast and another on her hip and she starts to slowly grind on top. She gets up for a second and to my surprise, she slides my dick in her ass. This was the first time to have anal sex in that position. She started moving slowly and then out of nowhere, she gets on her feet while squatting down on my dick and basically starts riding/bouncing on my dick like that until I finally cum.

I probably cummed like a half dozen times within the last 4 hours but yet, I still wanted more. We went a couple more rounds for the next several hours. She even used her vibrator at one point when I was fucking her ass. It was about 4pm and we both decided to shower together. My Gf was not going to be home until 9 or 10pm so I was not worried. In the shower, we washed each other’s body and she started giving me a blowjob. My dick was hard but I didn’t have much in me to cum again. We finally get out of the shower and just enjoyed each other’s company. We hanged out in the living room watching tv, we cuddled, talked about sex and even brought up the idea of having this again the next summer.

It was roughly 8pm and I texted my Gf what time she was coming home. She was preparing to leave from her regional meeting which was 2 hours away. I looked over at Maria who was just on her phone and I leaned towards her and kissed her. I started to undress her again, I knew this would be the last time we had any opportunity to be this free. We went to her bedroom and continued there. Without going into specifics, we did everything from oral to vaginal and anal sex again. It felt more like a make-out session than actual sex because we were both exhausted from going at it all day. We went at it for another hour. I went for a quick rinse after I finished and soon after, my gf came home. While I was in the shower, Maria went to the pharmacy to buy her plan B which I paid for.

————–

For the rest of the time that Maria was there, we still touched each other and would sneak a kiss here or there. Maria finally left the following week, my Gf and I drove her to campus which was about 3 hours away from our home. I was also starting classes back up so I was excited (Sarcasm). Maria and I didn’t talk to each other about our secret. She normally just messaged me through a group text with my Gf. I did think about her a lot on how much I wanted to see her but I had to remind myself to stay away. My GF and I broke up a couple of months later. It had nothing to do with Maria, there was just some drama with her family that made things difficult for me to be in the picture. I never followed up with Maria. I know a lot of you have asked if I keep in touch with her but I don’t. She pops up on my “people you may know” on social media but I ignore it. I am currently with someone right now anyway. Please let me know if you have any other questions.
