The strapon promise SeXStoRY

She kept her promise about the strapon and here is a story about the first time my s*ster fucked me using a strapon for the dildos: Some time had passed since that day my s*ster found out about my anal cravings, and helped me give in to them with her dildos. I still remember that day when she gave me that dildo I had borrowed from her without asking, as she had found me on Her bed stuffing Her dildo up my tight craving hole. A day when the most embarrassing moment turned into the most hot and dirty sexual experience I have ever had. I had been using that dildo from time to time when I was alone and felt the urge to fuck myself. The guys that had sex with me regularly had started to notice its effects. They loved my better and better ability to take their big cocks and my endurance when it came to having my anal penetrated for long session. I loved it to as it did not hurt as much now that I could prpare my ass properly for the cocks. I had however forgot about the strapon my s*ster promised to buy. It was late in the afternoon mum, dad and my s*ster were all home and we were in the kitchen eating together. When we were just about finished my mother said asked my s*ster about school and she said it was going fine for her. As she did not have anything she needed to do this evening she turned to me said the following right out of the blue: "I'll help you with your homework, what do you say?" I looked at her surprised as she had never helped me with my homework before. "Are you sure?" I asked her. "Yes why not, let's go to your room I'll help you get it on" she said with a wink and a subtle grin. I remembered that look on her face as it was just like that day in her room. I thought it must be a joke. She would not want to do it when our parents were home right? When we had finished up in the kitchen we both strolled back to our rooms and entered my room shuting the door behind us. I turned to my s*ster and she now had that teasing smile on her face like before. I knew what she wanted. "Let's get it on huh br*ther?" she whispered and looked through my drawers obviously searching for the dildo. "It's not there" I said and dropped down on my knees and took out the dildo from under my bed. "Oh I see, well take your clothes off then" she whispered and grabbed the dildo from my hands. "Are you mad? I can't do that now!" I whispered back at her alarmed but she just shook her head and put the dildo down on my bed and help me off with my T-shirt. "Just relax they won't notice" she said and gently pushed me onto the bed. I did as I was told and unzipped my pants before she dragged them off. I was now lying there on my bed in my underwear and socks with the dildo beside me and our parents were just outside walking around the house. They had no idea what was about to happen here in my room. "Ok, turn around now so I can see how well you have practiced, cause you have done that haven't you?" my s*ster whispered as she held the dildo in her hand. I turned around and presented my butt to her arching my back a bit in an all too familiar pose. "Oh tihi, you are no rookie are you?" she whispered with a giggle as she dragged down my undies exposing my hole. "No many guys have taken me in this position" I said quietly as the dildo was pushed against my ass. "I bet, who could resist that butt huh, now stay quiet and don't moan so they hear us" she whispered as she inserted the dildo all the way up my butt. She continued to slide in and out a few times and then took it out almost all the way. "Good boy look at that, not bad really" she said quietly as she inspected my ass as it opened for the dildo. "Now, stay quiet" she said and started to jam it in me hard and fast. She fucked my like that for a couple of minutes and then I rolled over on my back and she continued as I lay there with my legs up against my body exposing my hole for her. After a while she took hold of my now hard cock and started to jerk it for me. I lay there and just enjoyed as she fucked my ass and jerked my dick off. I later felt I was about to cum soon and she just said: "Go on , do it it's okay" as she stopped fucking my ass and bent over me starting to suck my cock. I was very surprised but could not keep myself from shooting my cum right in her mouth as she sucked me off hard. "Why did you do that?" I asked as she opened her mouth and showed me my cum. She swallowed and then said: "mm I 've always wanted to taste you, just once" I did not know what to say. "Now hurry get your clothes, and br*ther, I'll be back" she whispered hastily as I got up and tried to find my clothes. "Are we gonna do this again?" I asked and I put on my shirt. "No better yet, I have the strapon" she said winking as she carefuly opened the door and went outside. Later during the same week we had some time for ourselves as our parents were away. My s*ster ordered me to as soon as I was home and our parents had left the house I was to undress and wait in my room. I did so and lay there naked on my bed as she came home early just like that first time. She got inside, left her things in her room and walked into my room: "Hi, good boy I see you are ready for me" she said and left again and when she came back she had that large dildo of hers she had used on me before but now it was attached to a strap-on device. "Are you ready for this though hehe ?" she said with a laugh as she showed me the huge strapon dildo. I was a little hesetant at first but then just smiled and said: "Yes please use it on me s*s" She smiled at me and to my slight surprise undressed before putting on the strapon. "What you think I'm going to fuck you with my clothes on? relax sissy" she said and stroke the dildo with her hands. I felt hot as I looked at her wit hthat monster between her legs. She then walked up to me and got up on the bed. "Stay there now" she said as I was about to turn over and she then sat above me the dildo resting at the side of my neck. "Suck it first, don't you do that to the guys?" she said as she grabbed the dildo and led it to my mouth. I complied and open my mouth wide and took the huge head in my mouth. I licked it and sucked on it for a moment before she pushed and I knew she wanted more. I let it further in but had some problem with it because of the size so I gagged on it a bit as she pushed. "Take your time, we got all day" she said and continued to try pushing her cock deeper in. After a little while I got used to it and was ready for some deepthroating as I knew she would not be satisfied until I did that. And I really wanted that cock of hers in my ass so I did my best. I took some deep breaths as I jerked the dildo just as I would do with a guy's cock as i rested my throat. "Come on br*ther you can do it!" she said and I opened wide again and she pushed her cock inside my mouth and onwards. I felt I was about to gag again as the it reached down my throat but I stayed calm and just shook a bit as she pushed it deeper and deeper. "Good job, I knew you could!" she said cheering me on. "And if I were a guys I would want to do this by now" she continued and started to fuck my throat making me gag slightly. "mm, I bet they love your mouth too right? you seem to be good at blowjobs too" she said as the dildo went in and out of my mouth and throat. After a while of hard throat fucking she let me suck freely on the strapon as she stroke my cock, which was tiny compared to her huge dildo. It felt good sucking on that huge dildo as she jerked me off. "Ok, now my dick is ready for your tight little butt" she said and moved out of my way so I could change position. I posed just like I would for a guy, arching my back presenting my ass for her to take. She gave my buttock a gently tap with her hand and then let a finger run down my buttcrack to my hole. She spat at it and pushed a finger inside and moved it all around to lube it up with her spit. "You want it?" she asked as she put two fingers inside my ass. "Yes I want it now" I answered and started to fuck her fingers as she held them inside me. "Say it then, say that you want your s*sters cock!" she said and smacked my buttocks hard. "I want your cock s*s" I said. "Louder" she said as she put another finger inside me. "I want your cock inside me!" I shouted at her. "There we go, hehe you dirty slut" she said with a giggle and withrew her fingers. I then gasped loudly as her cock entered my tight hole. I felt it stretch me wide open as she pushed it deeper and deeper very slowly. Every inch hurt but I did not say anything I did not want her to stop I wanted it so I did my best to endure the pain. She were So deep inside me now I could barely breathe but then I felt her thighs pressing against my butt. It was in. She had pressed the huge dildo all the way inside me and I loved that feeling. "Wow you took it all, you are such a slut aren't you" she said wiggling the strapon a little. "Fuck me please" I gasped and so she begun. "Oh yeah!" she moaned as she moved backwards pulling the dildo out from my hole. But then right at the base of the head she rammed it back inside making me scream. "Oooh yeah, take it bitch!" she said and started fucking me moving her hips very firmly. She was really fucking me, my s*ster was fucking me with that monster cock of hers! I moaned loudly and gasped for air every time her cock reached all the way inside me as she thrusted away enjoying it. She started to pich up the pase and the dildo was now moving in and out of me faster and faster. "Yeah, I love trashing your tight hole slut" she said breathing heavily. "You're So big!" I gasped at her. "I understand why the guys like you so much hehe" she said with a laugh and moved back pulling the dildo all the way out of me. "On your back now as I know you like it you whore!" she commanded and I rolled over slowly feeling the soreness of my nearly numb anal. She pushed my legs up and I held them tight against my body as she inserted the huge strapon yet again. She humped hard against me as her huge cock went in and out, in and out all the way with every stroke. "You are such a little anal slut, you can really take it good!" she said as she pushed her cock inside me as far as she could and then started to make short quick movements with her hips giving me a hard deep fuck right there. She was fucking me as far inside my tight anal as possible and I felt the pressure and strain deep there in my abdomen. She then finally pulled out and continued to fuck me with slower enlongated movements so that the dildo almost fell out of me every time. She then let it fall out and inspected my now widely gaping hole as I saw sweat drip from her face. I was all soaked as well by now, had not even noticed until now. "Wow look at that hole, you can see all the way haha" she chuckled as she slid the strapon in and out several times to see the effect on my ass. She then sat down beside me on the bed and held the dildo up in the air. "Come ride it little br*ther" she said spitting on and stroking the dildo in her lap. I moved slowly trying to recuperate from the exhausting sex she had given me already. "Come on be quick about it hehe!" she said. I sat carefully down on her cock and felt the pain from the penetration before and hissed a bit. She gently stroke me on my back and guided me down into her lap. I thenstarted riding up and down carefully. "Good slut" she said and helped me with her arms and I started to go faster and faster as the pain started to fade from the renewed stimulation. I rode her dick just as I did with all the guys and felt her huge rod penetrating me very deeply every time I bumped against her thighs. I worked like a machine now up and then down again up on the cock and down on the cock. "How do you feel now slut?" my s*ster asked after a while of me riding her strapon hard. "I don't know s*s" I uttered now breathing very heavily. "I think you need to come huh hehe" she said with a laugh and stopped me riding and helped me off to the side. She then sucked my cock which was now a bit limp until it was hard again. "Now finally you can cum" she said and drove her cock inside me again and started fucking me for a last time. She took hold of my cock too and jerked it while fucking my now wide open and sore hole. After just a little while I came hard and sprayed cum all over myself and her hands as I felt my ass clenching against the dildo inside. "How was that br*ther? did you like it" she asked as she pulled the dildo out of me slowly and rubbed the cum over my chest and fed me some of it with her fingers. "That was awesome s*s" I answered as I swallowed the cum she made me eat from her fingers. "s*s fucks you best doesn't she" she said with a teasing voice.
