I bedhopped from my gf to her sister, in the same night. [MF]

It’s a long one, sorry!

When I was 25, I dated a girl called Kelly, who was 24. Kelly was tall for a female, about 5’10. She sported shoulder length, dirty blonde hair, that was dead straight. Crystal blue eyes, and a big bright smile.
Her body was in good shape, with nice curves in all the right places, and large D cup boobs.
We were both healthy, fit young adults, and we had sex a lot!
We pretty much fucked every chance we got. In our cars, at the mall, every room in our houses, even a couple times in the forest.

Kelly and I still lived at home with our respective parents, at the time, (we were both saving up for an apartment together). We both had decent jobs, and things were going great, except for one small thing…
Kelly had a little sister.

Amanda was pretty much the opposite of Kelly. She was 18, about 5’2 and around 135, so she’s got some extra pounds on her. She wore short, jet black hair, in a pixie cut and had deep brown eyes, all framed within a cute round face. I didn’t know for sure, but it looked like she was a B cup.

If you could describe them, Kelly would be a sex tiger, and Amanda, a cute cuddly kitten. They were both attractive girls, just in very different ways.

On the night in question, we were all hanging out at Kelly’s house, with her parents. We had dinner together and sat in the lounge to watch some tv. Kelly’s parents were really cool, and they liked me a whole bunch, so this was a normal occurrence. Kelly and I sat snuggled on the love seat, her parents in 2 single seaters, while Amanda was lying sprawled across the sofa.
It was getting pretty late, and I was feeling pretty horny, so I began to play with Kelly’s hair, and gently rubbed her legs, to let her know I wanted her. She knew my signals and gave me a sweet smile, then leaned over and whispered in my ear, “Ive got crotchless panties, I want you to fuck me while I’m wearing them.”
I immediately started to get hard, and had to rearrange myself so that I was comfortable. I looked over at Amanda, and she was staring right at me, with an eyebrow raised. I stuck my tongue out at her, and stood up to use the bathroom.
When I was finished, I walked back with every intention of saying good night to Kelly’s parents and to drag Kelly to bed to wear those panties out, before heading back home to my house, for the night.
As I walked down the hallway, I saw Amanda walking towards me. I noticed that she had changed into her pjs, and I gave her a big smile, “Hey, off to bed so soon?”
She stopped and gave a disappointed frown, “Yes, but I don’t get to bring a sexy man to bed with me, not like Kelly.”
I was a little surprised by her answer, she doesn’t normally flirt with me. Occasionally I see her looking at me, and she has caught me looking at her a few times, but never anything more.
She walked up to me, I could smell her perfume strongly; it was… intoxicating.
I looked down at her and realized just how cute she was. Her curvy figure looked amazing in her silky button down shirt with cute booty shorts.
She must have caught me staring, as she placed a hand on my chest, “When you are finished with her, come by my window and tap 3 times.”
And she slid past me, into the bathroom.

I was very confused, but very horny at that moment, and walked right into Kelly, in the kitchen.
“Hey, are you alright? Ready to go to bed?” She asked.
I snapped back to reality, at the sound of her voice, and nodded with a grin, “As long as I get to tear your pussy up.”
She took my hand and slid it down the front of her shorts, and panties, “I am all ready for you.”
My cock stiffened as my fingers brushed her landing strip, and slid further to her wet pussy. She was ready for me.
The sex was amazing, as always. The crotchless panties allowed easy access to her dripping, tight snatch, and she decided to ride me for a solid 45 mins before I flipped her over on her front, and squeezed my cock between her thighs, and into her. Pinning her arms down at the shoulders, I began fucking Kelly faster and faster. She started talking dirty, with plenty of “Fuck yes!”, and “Cum inside your dirty whore!” Spewing from her lips.
After another 30 mins, I released inside her. It felt incredible to fill her pussy up with my hot cum.
Feeling spent, I lay next to her, and we made out some more, before I said, “I really should be heading home. See you tomorrow?”
Kelly snuggled into her covers, and sleepily lay her head on her pillow. “Sure thing Stud.”

I got dressed and slipped out the back door, as normal. My car was parked around the back of the house, and I didn’t really think about it until now, but I walked past Amanda’s room each time I came out here. Her room was on the other side of the house, and she was pretty much by herself. I gingerly walked up to the window, wondering if this was some sort of trap. I raised my hand up to knock, and stood there for a solid 20 seconds, just waiting.

Suddenly, the blinds rolled up and I was face to face with my girlfriends little sister.
“Are you gonna stand there like an idiot all night, or do you want to come in?” She said through the glass.
“I, er… I… sure.” I stumbled over my words like a fool.
She unlocked the latches, and effortlessly slid the window upwards. Amanda stuck her hand out as an offering to help. I took the offer and climbed into her room.
Her room was pretty different to her sister’s. While Kelly’s was elegant with soft pinks and everything matching, Amanda’s room was a jumble of blacks and greys. Nothing much matched, and there were teddy bears lining every shelf I could see.
She sat on her bed, and said, “I’m glad that you came. I wasn’t sure if you would want to.”
“To be honest, I’m not sure if I do… Amy (my nickname for her), what ARE we doing?”
“Well… I’m jealous! I know that you both have sex every night, and ive barely kissed anyone. I want to fuck someone.”

I walked over to her and crouched in front of her. Putting my hand on her knees I tell her, “Listen, Amy, you will find the right guy. They would be stupid not to, you are so cute, and any guy would be lucky to have sex with you.”
She lifted her face to look at mine, “Well how about you? Do you want to fuck me?”

Before I could tell her how I couldn’t do that to her sister, she wrapped her arms around me and kissed me on the mouth. It was warm, wet and arousing!
I pulled away quickly, and we stared into each other’s eyes for just a moment, before I said, “Fuck it.” and moved forward to kiss her again. My momentum pushed her backwards, and I ended up on top of her.
Her legs wrapped around me and I began grinding on her. My cock was rock hard right now, and I was pressing it right against where her teen pussy was.
She softly moaned before saying, “I want you to do to me, exactly what you did to her.”
Grinning, I said, “Amy, you couldn’t handle it, but I’ll certainly give you something to remember.”

I began kissing her neck, and as I slowly went down to her chest, I unbuttoned each of those buttons from her shirt. Revealing her perky B cups, I licked and sucked on each in turn. Down her stomach, to her navel, I stopped and slid my fingers around her shorts and panties. In one pull, I whipped them down to her knees, and then proceeded to remove them completely. In front of me, legs spread, was the younger sister of my girlfriend. She wasn’t shaved, but trimmed, and it looked good. Her lips were puffy, and she looked wet. I glided my hands from her knees to her hips and bend my head down to taste her. Nothing tastes better than 18 year old pussy.

After stripping down myself, I began to lick her. I had her writhing and moaning within minutes. I could only just manage 2 fingers inside her, she was so tight. I concentrated on her clit for about 5 minutes before her hands grabbed the covers of her bed, her back arched, toes curled, and for a moment, I swear she stopped breathing. Then her body went slack, and the only sounds she made, was the rhythmic panting of her breath.
“Ho…ly shit! If that was an orgasm, then I’ll be doing that more!”
I chuckled, and made my way up to her face, and kissed her gently. “Pretty good, huh?” I said.

She looked down between our bodies and saw my cock. “Looks like you still need to finish, Sir.”
I arched an eyebrow, “Are you sure you are ready?”
Amanda reaches down and began stroking me. “You bet I am.”
I held my cock and rubbed it up and down against her pussy. I knew I wouldn’t last long, she was so tight.
I pushed gently and watched the tip press in. Feeling some resistance, I pushed a little stronger until I was about half way in. Looking up at my gfs sister, I asked if she was alright, and she nodded.
I raised her legs to open her up a bit more, and slid the rest of the way in.
She gasped and groaned with pleasure as I began to get into a rhythm. I bent down to kiss her while still fucking, and she whispered, “Don’t cum in me, okay? I’m not on birth control.”
I nodded and started to really pick up the pace.

Between fucking my gfs little sister, having no protection, and how tight she was, I was ready to cum in less than 10 minutes. I pulled out of her and sprayed ropes of semen all the way from her pussy to her neck. Amy lay there, completely satisfied. She began to rub the cum on her boobs, and licked one of her fingers.
“Tastes good, maybe I can take it in my mouth, next time?”
