Best pussy ever

I had sex with my friends down syndrome daughter true story

One of my friends from work has a non verbal 12 year old daughter with down syndrome. He was a recent single dad and on occasions I would watch her over night while he stayed the night shift. I never really thought of her sexually until this time. I arriver around 8pm and he told me she was still awake and have her go to bed at 830.
I went in and could hear her watching cartoons in her room. Around 830 i went to tell her its bed time and she was laying on her bed completely nude. She is very short , her breasts were massively developed. I felt my cock bulge at the site of her large pink nipples. The next thing i noticed was she had a full pubic bush covering her vagina. She made a noise and kicked up legs up and laughed. I went and sat at the edge of the bed, my cock stiffening in my pants. I decided to unzip and pull it out to see what she would do. I pulled it out and gave it a few strokes. She watched but didn’t really respond. With my other hand i reached over and spread her pussy lips open. She propped herself up by her elbows and watched. I slowly opened her pussy hole and she grunted and cocked her legs open. I wondered if she had had sex already. I took this as an invitation and quickly removed my pants. I hovered over her for a min, my cock throbbing in the air. She grunted again and i slowly lowered myself until the head was at her hot wet hole surrounded by the tangle of pubes. I slowly pushed. She laid back and cupped her own breasts. Her huge tits spilled out of her tiny hands. I loudly groaned as i gave a forceful push. I slid in and have never felt anything like it. She let out a loud Huhhhhhhh! And her legs quivered. Her vaginal walls were so tight it felt like a grip. I pulled back to give another slow push but her pussy held on like a fist and gave me a tug. Oh god i said out loud. She was now grunting beneath me like an animal. I started rocking inside of her. Her pussy tugging me, jscking me off. It didnt take long until i let loose one of the biggest loads I had for a while. I tried to pull out but she still had a grip around my cock. She grunted, moving her hips in small little thrusts. I collapsed on top of her and soon her pussy was smacking around my cock in an orgasm of her own oh fuck yes i whined as she grunted and groaned. We laid there motionless for about 10 minutes until i was flaccid enough to slip out, followed by a gush of cum. I worried about her leaking cum or the massive cum stain this would leave. I took her to the bathroom and had her sit in the tub. Afterwards i put pajamas on her and she went to bed with no issues. This was about 3 weeks ago and my friend hasnt said anything suspicious to me yet but I also wonder if he has sex with her cause she seemed to enjoy it and like it wasnt her first time.
