so yesterday, i was chilling wit my girl at her crib and she went out with her friends and told me to watch over her sister. im 17 my gf is 17 and her sister is 16.

after she left her sister called me into her room and was like making jokes and shit and gave me some chocolate. im pretty sure it was horny chocolate and then she told me she wanted to play a game.

it started off innocent like try not to laugh but then it got progressively sexual, she was like every time you laugh you have to take some clothing off. and i didnt say no cs i dont want her to make up sum bs to my girl so i just went with it. after i had like all my clothes off only my boxers, she told me to close my eyes for a sec. so i closed them and she started shaking her ass all over me i peeped my eyes open and saw ts.

we were both horny asf so i told her she could do wtv she wanted with me and i wouldnt snitch to her sister. so she took my boxers off and starting giving me the best head of my fucking life. better than my girls lowk.

after she sucked me off i painted her face with my nut and threw her on the bed and gave her backshots of doom.

we were the only ones in the house so we were loud asf. i kid you not as soon as we stopped i heard the front door open and heard her walk in.

nothing rlly happened after that but i feel a little guilty but also good asf. should i keep fucking her sister on the low or stay loyal.

For reference, I’m the middle child of my family, I have 2 brothers and myself. I’ve never been ugly but over the last 2 years or so, my figure has become a lot more curvy, and I’ve become more alternative, so a lot of guys call me a “goth girl” now.

Anyways, today was my younger brother’s birthday, his 18th for that matter. He isn’t a bad looking guy persay, but not really my type. Compared to my older brother, he’s less shy and more energetic generally. Since I’ve grown a bit more into my figure, I’ve also caught him staring a lot at my tits, and he always talks about how he wants a “goth baddie”.

For his birthday, I was the only one awake at midnight, since my older brother was out and my mom was very sick that day, so she was in bedrest. So as the clock struck 12, I went to wish my brother happy birthday, I had even prepared a slice of cake and everything, but I hadn’t had time to get him a present.

As I opened the door, I saw him jerking off, one hand on his dick and the other holding his phone as i opened the door. I was dressed in just a bra and some pyjama trousers. His dick was throbbing, and I couldn’t take my eyes off it for a few seconds before leaving the room, until I heard him say “come in”.

I walked into his room, his dick was still out and throbbing, easily over 6 inches, maybe around 7-8, which is huge considering i’m barely over 5 feet tall. In a fairly confident tone, he asked “how about you… take care of this for me, for my 18th birthday?” I looked at him in shock for a few seconds, but after my eyes went back down to his cock, which he was teasingly stroking up and down, I sunk to my knees and started taking him into my mouth, at the beginning, I was in control, my mouth was moving up and down his thick shaft, he tasted so fucking good that I wanted to deepthroat his thick dick, but it was honestly too big for me to. This continued until he was nearly about to cum, I could feel his dick throbbing in my mouth, and without warning, he grabbed my hair and yanked it, forcing me to the base of his cock.

From there, he ordered me to take my bra off, and started twisting and pulling my nipples while I sucked his dick, looking at me as if I was a whore, while I was moaning and squealing in pleasure. He began to thrust into my mouth, using it as a fleshlight practically, hitting the back of my throat with each thrust, he would grab the back of my head, using it to keep on fucking my face until i felt him cumming down my throat, he kept me there, yanking my hair so I would look up at him, my makeup was getting ruined, forming black streaks from my eyes. As he finished, his dick was still hard, and without warning, he flipped me around, pulling down my pyjama trousers and slipping my panties to the side.

He held me by my tits and started to fuck me like it was a porno, one hand on my tits and the other forcing two of his fingers into my mouth, I could feel his dick stretching me out, I couldn’t stop moaning if I wanted to, even with his fingers in my mouth, and the sounds of his skin slapping against mine filled the room, my eyes rolled back involuntarily as he continued to fuck me, basically not caring about my pleasure, only using me as a sex toy, and I loved every second of it, I didn’t think size mattered until right then, and I couldn’t stop myself from cumming.

As I came, he went even harder, pushing me onto the bed and proneboning me, I could feel every inch of his dick inside me, and my legs went limp as he continued to fuck me, as he got closer, he flipped me over into a mating press, and started fucking me even harder than he was earlier, forcing my legs behind my shoulders as he used me, groping my tits and forcing his tongue down my throat. As he finished, he came inside, even though I begged him not to, but as he filled me up, I was in bliss, my body shaking and convulsing on his cock.

As he pulled out, he only said “good girl” and then he helped me to bed, since I could barely walk, I slept for 11 hours tonight. I would fuck him again, but at the same time, I have a date with a guy tomorrow, and don’t want to become attached to my brother, what do I do?
