[MF] My sister wasn’t fucking him, so her (F18) boyfriend (F20) creampied me (F20) instead

This story is from thirteen years ago when I (F20 at time) was on summer break from college. My sister Jane (F18 at time) was going out with a local guy Matt (M20) for a few months. I had been in school with him but didn't know him well until he started dating my sister. Matt was tall, athletic and handsome, dark hair and a bit of a stud really.

Admittedly Jane was hotter than me, she had a perfect body, tall, long legs and perfectly proportioned boobs, and gorgeous facial features coupled with long flowing dark hair. She was also a champion multi sport athlete, excelling at gymnastics in particular. She would go on to a prestigious scholarship when she finished school.

I was also very pretty in my own right, a little shorter and a bit stockier but by no means heavy, and I had nice big perky boobs that I never tried too hard to cover up. But Jane was on another level. At family events everyone would comment on how stunning she was, but there were rarely ever similar comments about me. Being continually overshadowed like this by my sister was annoying and sometimes hurtful, but I wasn't blind, I knew the reason.

She and Matt hadn't had sex at this point, how I know that comes later.

Anyway, one night I was out drinking with friends and I bumped in to Matt at a bar. My sister was away all weekend at a gymnastics competition and wasn't with him. My friends were going home when he came over and offered to buy me a drink.

We chatted and laughed a while. He was extremely charming and funny and great fun to be around. There was a definite air of flirtation going on between us, I felt it and I'm sure he did too.

When the bar closed it was just the two of us left from the group as our friends had gone home. Matt told me that he had some beer back at his house and he invited me back for a drink. His parents were away so he had the house to himself that weekend. I was reluctant and said no at first but I knew I wanted to go. I had had a lot to drink and felt I wasn't done drinking so eventually I agreed as Matt kept persisting.

I did wonder if there was more to this invitation. Matt was sexy and I was definitely attracted to him. My mind wandered to what might happen back at his place and naughty thoughts took over.

His house was a short walk away, it was a nice townhouse that was fabulously decorated. He opened two beers and we sat at the kitchen island and talked some more. The flirting got a little more obvious after he made a passing remark about my cleavage, and I knew before long that we were going to end up doing more than talking.

Eventually he got up and walked over to me, kissing me on the lips.

"I've wanted to do that all night" he said

"Me too but we can't, what about Jane?"

"She'll never find out. It can be our secret."

He kissed me again and I didn't stop him. Instead I reached for his belt and undid his pants, sticking my hand down to find his semi hard cock. I could feel the precum on my hand as I felt up and down along his shaft. At this point there was no going back and I wasn't even thinking about the consequences of what I was doing.

I pulled his pants and shorts down as far as his knees and he sat back against the kitchen stool. His cock was fully hard now and he was as big as anyone I had been with before that. It was probably 7" with plenty of girth. I started blowing him slowly, switching between working my tongue up and down along the shaft and taking him in my mouth.

"Oh fuck that's good."

I stared up at him and our eyes locked as I worked my tongue up and down his cock. The naughtiness of what I was doing made it so good for both of us. I could feel the moistness in my panties as I looked up and saw how much he was enjoying the blowjob.

"Jesus Christ that's amazing" he said as he groaned with pleasure.

"Let's go to the bedroom" he said after a few minutes. I would have happily blown him until he came right there in the kitchen but the bedroom sounded good.

He led me upstairs by the hand to his double bedroom. It was messy with clothes thrown everywhere, but he had a big double bed that looked inviting. He lifted my top over my head and unclipped my bra as we stood in the middle of the floor, before cupping my tits and lowering his head to kiss my nipples.

"You've no idea how much I've been thinking about these, your tits are fucking amazing."

"Have you been ogling my tits while you're in my house to visit my sister?" I joked

"I can't help it"

We both got fully undressed a little awkwardly. I pulled my jeans and panties down to reveal my shaved pussy and he immediately came over and put his hand there, finding my clit and starting to gently massage it up and down.

I motioned him to stop and then pushed him playfully down on the bed before picking up where I left off from downstairs. He pushed himself right back on the bed and rested his head on the pillow with his cock sticking up invitingly.

I got back to work but didn't make him cum because I was craving his cock inside me. I hadn't had sex in over a month, not since I came home from college for the summer. I had also just gone on birth control for a menstrual issue and had decided that I'd let him go raw, and was excited to get my first creampie.

I moved up beside him shortly and we started kissing, his hands caressed my tits before he moved down and started playing with my clit again. He could feel that I was dripping wet and ready for him. He whispered to me that he would get a condom but he got a pleasant surprise when I told him there was no need. I explained that I was on the pill and that it was safe and we were going raw.

I got into missionary position and spread my legs apart for him, taking his cock in my hand as he climbed over me. I guided the tip of his cock to my pussy and let out a low ‘mmmm' sound as he pushed it gently inside.

He thrust slowly at first, before quickening and taking my legs over his shoulders. He took control and I loved it. He continued thrusting hard until he told me he was ready to cum, as if checking was it still ok to nut inside me.

"It's ok, I want you to cum inside me."

It was my first time going raw with anybody and in truth I couldn't wait for him to cum. Very soon after I could feel his load spilling in to me as he groaned with pleasure. I had always wondered what it would be like and I loved the sensation of warmth as he squirted deep in to me.

He pulled out and immediately started working my clit again with his fingers, and after a few minutes I could feel myself building up to orgasm. He sensed it too and stayed going until I was writhing on the bed and feeling the euphoric release as I came with an intense burst of pleasure throughout my body.

I pushed his hand away and we both lay there for a few minutes.

"I think I saw heaven" Matt said.

"You liked it?" I teased

"Are you joking, it was unbelievable".

I reached for his cock again and could feel he was nearly hard.

"That didn't take long" I said jokingly.

I put my hand on his chest signalling him to lay down as I got on top of him. I took his cock in one hand and massaged his balls with the other for a little while. I could see he was loving it, and when he was fully hard I pushed up on my knees and slid gently down on him, his cock went in so smoothly and we made a loud squelching sound as I started riding him cowgirl, moving up and down slowly and deliberately leaning over so that my tits we're nearly in his face. He was rock hard and having the time of his life.

He fondled my tits and licked and kissed my nipples as I rode him, grinding my clit over his pubic bone. This lasted at least fifteen minutes and neither of us wanted it to end. Eventually he came inside me again, thrusting upwards as he groaned and moaned with pleasure.

He emptied his balls into me another three times over the next few hours, lasting longer each time, and making me cum with his fingers in between. The feeling of fucking raw was still a novelty and I couldn't get enough. He pumped me doggy style for probably 25 minutes straight. It was absolutely amazing watching him pound me from behind with my head buried in the pillow before he spilled yet another load of cum in to me.

His stamina was unbelievable and we couldn't keep our hands off each other. There was cum all over the bedsheets when we finished, it was insanely hot.

I would have loved to have stayed the night and fuck him again in the morning but there was too much risk of being caught so I figured I had to go home. As I was leaving I warned and begged him not to tell anyone what we did because I was paranoid as fuck my sister and family would find out. They never did, but I had massive feelings of guilt and embarrassment so any time he was around after that I'd make an excuse to be somewhere else.

A few weeks after our night together my sister told me they had had sex and that it was the first time for both of them! I was like ‘WTF' but obviously couldn't say that I knew he wasn't a virgin. I don't believe I was his first either because he was too good in bed for that.

I was freaking out thinking about the constant awkwardness if they stayed together, and the ongoing risk of getting found out so I was relieved when they broke up in the end, and thankfully my secret stayed buried.

I still get a little turned on thinking about it. He obviously played us both but it was an amazing night that I can't say I regret at this stage.
