Mom Grounded me... So I fucked her boyfriend SeXStoRY

My name is Kayla and I was a typical teenage girl, Hanging out with friends, going to parties, doing things things I probably shouldn't have been doing like drinking with my friends and smoking cigarettes, I had just turned 18 and to me my life was already in ruins my mother and father had gotten a divorce and I had been dumped my boyfriend of 8 months, my mom started dating about a year and a half after her and my father split, His name was Mike he was 30 and from what I could tell the couple times I met him he was a decent guy, Usually I was too busy running around town wreaking havoc with my friends, when I first met him it was a quick "Hi" as I was running out the door to my friends car. My friends would come over and we would have a slumber party and watch movies, one night we were watching a movie when Mike came down from upstairs and my friends got suddenly quiet, After he went back upstairs my friends asked "Is that him? is that your moms new boyfriend?" Yeah I said and they all replied "Wow you are lucky he is so cute" I just said you guys are perverts but they insisted that he was very sexy and that they would totally make out with him, I just shrugged it off and enjoyed the rest of my night. One day me and my friends were going to the swimming pool in town so I got dressed in my brand new two piece bathing suit that my mother diden't really approve of and ran down stairs to meet my friends waiting for me in the car outside, I got to the bottom of the stairs and Mike opened the front door the same time I was going too, he stood frozen I noticed him staring at my body looking me up and down,I was about 5'9 160 lbs with blonde hair. I don't think he was trying to make it that apparent but it was anyway, He finally looked at my face and said "Have a good time". We got back from the pool way later than we anticipated I quietly snuck in the house and made my way upstairs, when I got to the top of the stairs I could hear my mom moaning, She and Mike were having sex, they diden't seem like they were trying to hide it with my moms loud moaning and the door cracked open lucky for me it was dark so I diden't see anything. the next morning when I came downstairs for breakfast, Mike was already at work and My mom had met me at the doorway of the kitchen with a scowl on her face "WHERE WERE YOU LAST NIGHT YOUNG LADY!!!!" she knew I hadn't come home when I was supposed too. I was going to have a comeback of "Well you dident seem too worried when you were fucking Mike last night instead of waiting for me to come home" But I was too tired for an argument so I apologized even though I was so angry because ever since she had met Mike she had turned into a total bitch, she thought she was so amazing because she walked around town with him on her arm like a trophy. Long story short I was grounded for a month and had my phone taken away I was furious, I went upstairs to shower while my mom getting ready to leave for work, I got in the bathroom started the water when I heard the front door close and her car start and drive away, "What a bitch" I muttered under by breath. I took my cloths off and stepped into the shower which was quite nice, it had an overhead shower head that made the feeling of rain and a little seat in the corner. I scrubbed my body trying to get the smell of chlorine off me from swimming in the pool the other day. I was rinsing the shampoo out of my hair when I heard "Kayla", I let out a scream it scared the hell out of me until I realized it was Mike, I peeked my head out from behind the shower curtain and saw the door slightly propped open with his nose sticking out, He said "I just got home from work and I dident wanna bother you but is it OK if I take a piss Ive been holding it since I left work" I kinda giggled and said "OK" He came in and I heard him peeing and for some reason I don't know why I peeked out from behind the shower curtain and had a full on glance of his cock, I was impressed, I have had sex before but my boyfriend was not very big about 6in but Mike had to have easily been 8 or 9, It was thick and had lots of vein's. I stared for a minute and suddenly I saw his head turn to look over towards where I was looking and I shot my head back in as fast as I could hoping he dident see me staring at his cock. I went back to washing my hair like nothing had happened hoping he dident notice, I cleared my eyes from rinsing out my hair when I saw him starring at me, for some reason I dident scream or try and cover myself I just asked in a sweet voice "What do you think your doing?" he responded with "Well you saw mine" with a smile on his face. I noticed even threw his jeans his cock was getting hard, I had an idea of what I wanted to do with him but I hesitated and then I remembered earlier when my mom was chewing my ass out and grounding me and at that instant I knew I was going to fuck my moms boyfriend. He was still looking my body up and down when I finally said "Are you gonna stand there or come in here?" He looked shocked but grinned and started unfastening his belt, he dropped his jeans and boxers and there was his cock now hard as a rock. I felt my body start to shake when I saw it, He took off his shirt and stepped in. There was plenty of room with me and him both in there like I said it was a big shower. he pressed his body against mind, I could feel his cock on my inner thigh and he started to kiss me and than my neck and than my tits, I had goosebumps instantly, the water was raining down on us as he ran his hand down my stomach and started rubbing my pussy, I tilted my head back and moaned as he slid his fingers in my one at first and than two, He backed me up to the corner little seat and sat me down, he knelt down on one knee and stuck his face in my pussy eating me out, I had never had that done to me before and I was glad I finally was,I was squeezing my tits as I felt his tung flicking my clit and him sucking on my pussy lips. At that point I was so wet and horny I sat up where I had his massive cock eye level with my face, I started stroking him not sure how to approach his huge cock but I slowly slid it in my mouth and worked my head back and fourth, I could barely get my whole mouth around it but I knew I was doing good cause I looked up at him, he had his head back and was moaning. I had both of my hands on his cock, one hand was twisting one way and the other hand the other way while I started to suck faster, He finally had to stop me cause he said he was going to cum. I stood up and he asked me if I had any condoms, I told him no because I was already on the pill, He kissed my neck some more and sat me down on the little seat again, this time he opened my legs, I had them as far open as I could get them. I was kinda nervous because I wasent sure if he was going to fit in me but all at once he slid the head of his cock in me and my body jumped, He asked if he wanted me to stop but I answered quickly "NO". He slid his cock in slowly inch my inch, it seemed like his cock had no end to it, he just kept sliding it in, at first it hurt so bad I felt like i was going to pass out but lucky I had the shower water hitting my in the face. He was finally all the way in me and it felt amazing after awhile, he was going very slow, All the way out and than all the way in. I had never knew with my ex boyfriend if he made me cum but after 5 minutes with Mike I knew he hadent. Mike had his cock all the way out and when he went back in his stomach met my thighs and he held it and I felt something I had never felt my legs went weak and my body started to tremble and all at once my head shot back and I let out a thunderous scream as my body felt like it had gone limp, I let out scream after scream of "Ooh my god!!!", I finally met eyes with Mike again my mouth was wide open and he just smiled at me with a crooked grin. After about ten minutes of him fucking me, I was getting uncomfortable in the shower seat so I told him I needed to sit up, he stepped back still hard as a rock, I sat up grabbed his hand and pulled him back towards me shoving his cock back into my mouth, this time I could taste my cum on him, I stood up and bent over and placed my hands on the seat, the water in the shower was staring to get a little colder from it being on so long but I dident care. He positioned himself behind me and I felt his cock slide in me again, my head shot back and I could hear him moaning, I turned to him and said "Fuck me harder" he was going slow because he dident wanna hurt me but I think my pussy had stretched because it dident really hurt any more it was just sheer pleasure. He started fucking me harder and harder and than I felt my body start to shake again, probably would have fell if he haden't had his hands on my hips so tight. I was cumming again, it wasent as intense as the first time but it still felt amazing. He kept fucking me from behind and all of the sudden my body jumped, I felt pain and pleasure at the same time, I turned my head back and he had shoved his index finger in my ass. He said sorry and I replied back with "No don't stop" he was fingering my ass while fucking me and within a minute I came again. He asked me if I had ever had anal? I said no but I liked his finger in my. with that he smiled and said "Don't move" he stepped out of the shower I heard the cabinet open and close and he quickly stepped back in, he had some Vaseline and was rubbing it all over his cock very thick, he whispered in my hear "Do you want me to fuck your ass?" and without thinking of the pain I said "Yes" I felt his cock sliding up and down my ass crack, I turned around he saw he had grabbed his cock at the base and was squeezing tight and soon as I felt the head start to slide in I slammed my head down to my hands on the seat and screamed louder than id ever screamed before. I felt like i was going to die with every inch that went in it felt like murder, he kept asking if he wanted me to stop and I kept yelling "NO!" as I had my fist in my mouth trying not to scream anymore, as soon as he said he was all the way in I came again and this time it was hard, I let out another thunderous scream with tears running down my face and all I could say was "Fuck my little tight ass!!" He stared slow but than sped up and I must have came two more times before I couldn't take it anymore and made him stop. He pulled out and I knew my asshole was gaping because I reached around to my ass and I slid four fingers in and I could feel that he had stretched me out good. I sat back on the seat my ass was getting very sore but i toughed it out, I put my knees to my chest with my legs up as he slid his cock in my pussy again, I kept saying to him "Shoot that cum on my face", "Destroy that little pussy" I could tell by his facial expression he was about to cum, he pumped harder and harder until he quickly stood up and placed his cock near my face, I shoved it in my mouth and started stroking it as quickly as I could until he let out a moan and I could feel my mouth filling up with his cum, there was so much of it, it was squirting out of the gap between my mouth and his cock, I pulled his cock out of my mouth and it was running out of my mouth onto my chest, I wiped it up with my fingers and slid them in my mouth swallowing as much as I could. We both got out and dried off the water was cold at that point but I don't think either of us noticed, we smiled at each other but dident say much I think we were still processing what had happened. I went to my room and jumped onto my bed with a huge smile on my face, and thought "Maybe I should get grounded more often?"
