I'm 28 years old. My older sister is 31. She also has a daughter who is 14. My 14 year old niece is super cute and i have imagined myself fucking her since she was 12. Her best friend happens to be mine and her mothers younger sister. Our parents never planned it, but got pregnant by accident and our younger sister is only 13. She is also super cute and i reckon even cuter than my niece.

Last night my older sister came to visit for the evening, and she came with both girls in tow. By later evening, around 1 am, both girls had crashed out on the lounge and my sister was totally drunk and headed to the spare room to sleep. I was not drunk, but was feeling it. I had some bad thoughts and after 30 minutes i decided to act on them.

Due to some previous work i did, i had a bottle of chloroform that i stole in my cupboard in my room. I went and got it and a wash cloth. Seeing both girls asleep laying on each of the lounges was hot. I gently used the cloth and gave them both a dose.

I checked my older sister and she was out. I made sure both girls were now knocked out. I decided to use my little sister first.

I gently spread her out on the lounge and pulled her panties off from under her skirt. I held her ankles up, pushing them back to lift her hips. I wasted no time pressing my cock against her tiny 13 year old pussy. Just knowing i was about to fuck my little teen sister i thrust home inside her. I only lasted 5 minutes, but i held myself as deep inside her as i could while i pumped my entire load into her pussy. She was so tight i just couldn't stop myself, and when i cum, the only thought in my brain was how hot it would be to put a baby in my little sister.

I cleaned her and put her panties back on. I left her with her tiny hips resting up against to lounge arm, keeping her hips slightly lifted so my load would leak out during the evening.

I wait 20 minutes and when i was ready, i gave my niece another dose from the bottle. I stripped her completely so i could really check her out. I spun her so she was laying on her chest on the lounge with her knees on the floor. I slide in from behind. It was just a hot knowing i was fucking my sisters little baby girl. I was able to fuck her for almost 15 minutes till i thrust home and blew my second entire load inside her tiny pussy. I gave her a short top up dose and i kept fucking her. I ended up laying her on the lounge and i mounted her. I Went so slow and gentle. I was inside her for almost 45 minutes before i sped up and pumped my last load into her pussy again.

After i clean and dressed my niece and placed her the same way i did my sister, with her hips slightly up, i headed to bed. Neither of the girls said anything in the morning to me or my older sister. They both showered and dressed and headed out to the shops. I'm hoping that it means they have no idea or just maybe they think they are just feeling off. But since all 3 are staying again tonight, i'm gonna get my older sister drunk again and hopefully i can get a chance to fuck another few loads into both my little sister and niece.

The only thought i've had all day in my head is i want to send both girls home with my babies in their tiny bellies. I really want my little sister to be pregnant.
