I had been flirting with My sister Jasmine for ever and ever. She was 18 to my 24 and she was a goddess and I was a nerd with a secret. When my GF Tammi and I had our last house party and Jas came over I deliberately got Tammi drunk and then told her that Jas wanted to know what sex was like. Tammi pulled Jas into our room and I listened by the door.
I could hear her talking to Jas in her drunk “quiet voice” telling Jas how she needed to find a man with a big cock like her brother - who could make her orgasm 4 or 5 times a night before cumming. Jas asked lots of questions - like what the best positions were for her - and what made me cum. Tammi spilled it all - even confessing that she had only made me cum involuntarily once - and that was when she managed to get me all the way in her throat but she wouldn’t do that again because she almost puked. Jas asked if Tammi still had her tonsils - and when Tammi said no - I grinned - knowing that Jas had her tonsils and adenoids out as a kid. Then Jas asked how big I was and Tammi laughed and said - oh honey - you know those small coke cans - if you stacked like 4 of them up - he would be that long and just a bit wider…
When my GF left on a week long business trip on Friday - I invited Jas over for a pool party Saturday. I came out with a towel wrapped around me (and nothing under that) and sat on the pool chair and just watched Jas move as she walked around and swam and finally laid on the pool deck near my chair facing me. Jas was one of those naturally sexy people that made any move hot - even just standing around doing nothing - she was someone you just couldn’t take your eyes off of. Now Jas had come over wearing a wrap over a hot but decent bikini. As she got ready to lay down and asked where Tammi was - I told her Tammi was gone for the week. Her eyes widened and then she grinned and reached back and slid the bottoms in making it a thong and kissed my cheek and whispered - just us then as she lay down in front of me and looked up at me.
Now since 14 I had always wore compression shorts to hide my hardons - mom had made me do that after the “incident” where she found my 17 year old cousin impaled on my cock screaming into a pillow as she came. My cousin said I started it with my hardon and she had just wanted to see it and then it was my idea to put it in her. Mom said it wasn’t my fault she was older - but I needed to cover it up. She took me out and bought me the shorts that day. What Mom didn’t know was that her sister came over when she was at work the next day - her daughter had apparently told her what had happeend - and demanded to see my cock. My Aunt had cum twice on me and was just catching her breath still impaled on my cock and telling me between heaves of breath that she could not wait for me to grow bigger because I was already the biggest man she had had in her. Thats when I accidentaly lost it in her. She was so mad and then she started to cry because she was not on the pill and her husband had been deployed for 3 months. She missed her period the next week but I kept fucking her secretly until she started to show and then Mom found out and put a stop to that by telling me that she would take care of my needs from then on out. That was great and all - but I was deperately and truly in love with my sister.
By now - My cock was throbbing angrily and I scewed up my courage and blurted out that I knew she was my sister, but that I had always been in love with her and when she was around me I could not think of anything else. Then I moved the towel and stood and said - this is how you make me feel Jas. She just reached up and wrapped her hand gently on my cock with a sweet loving look in her eye and said - well you had better get that in me fast then.
I moved her thong to the side and took her pussy from behind and her screams and moans as I stretched her to my girth were just like I had always imaginged. After her first orgasm she asked to ride me facing me in my lap and we took it slowly - and she came shaking and squiring hot piss all over me and then collapsed on me lauging. I lost it as I felt her breasts slide on my chest with her musical laughter and she gasped as I filled her - and she came again this time gently in waves. She grinned at me and said - how many women have made you cum in them - I asnwered only you Jas and then carried her to the bedroom. After taking her ass and giving my sister her first anal orgasm - she told me she was too sore - and then took me deep in her throat and her eyes winked up at me as she drained me completely.
Tammi found Jas riding me when she came home a day early. To both our surprise she just went and kissed Jas and - grinned and told me I get it and to be honest - your sister is so fucking sexy she gives me lesbian fantasys. She asked Jas if she could have the next ride and although she was suprsied to see Jas could make me cum in her - she loved making Jas cum on her face by eating it out of her. Tammi went off the pill that day and her and Jas ended up delivering the babies only 3 weeks apart
