I'm 31 F, and ever since I was around 12 I've had fantasies about watching my dad do stuff with my little sister (who was 6 at the time.) I would always picture that she'd be wearing really short fabric shorts that showed off her smooth thighs and the bottom of her tiny 6 y o ass cheeks. Then my dad would pick her up and sit her on his lap, bouncing her skinny body up and down so he could feel her underage ass on him. He'd get really hard and start running his hand on her calves and thighs, working his way to her inner thigh. Eventually, he'd lean her back and pull her little legs back towards her shoulders and start rubbing her slit through her shorts, pulling off her shirt to expose her flat chest and 6 y o tummy. My sister would start breathing heavier, wondering why Daddy was touching her between her legs. When my dad couldn't take it anymore, he'd set her down and pull her tiny shorts down so that his little girl was standing in front of him completely naked. She'd look so adorable with her pink baby pussy and tiny nipples showing, and my dad would make her get on all fours so he could get a nice view of her tight toddler holes while he jerked his thick cock. He'd have one hand on his dick and use the other to spread her little cheeks and pussy lips open. Then, he'd rub spit on her baby pussy and start to push into her. I'd watch her start to yell and kick her skinny legs as our dad's dick parted her 6 y o pussy lips. In one big push, he'd bury half of his 8 inch cock inside of her tight child pussy. My sister would cry and protest, but he'd just lean forward, push her face into the pillow and start bouncing his hips up and down, fucking his baby girl. Her tiny toddler pussy would stretch to it's limit, squeezing his big cock super tight. He'd taunt her by saying "squeeze it out baby. If you can push it out of you, daddy won't put it back in." She'd sob and squeeze her 6 y o pussy, pushing my dad's dick almost completely out of her, but he'd leave the tip in and laugh. "Nope. Almost sweetheart!", then he'd push his entire cock inside of her and start pounding her toddler pussy even harder while she shakes and screams into her pillow. I've been having this fantasy for soo long, and I get soaking wet when I imagine it, even though I know it's wrong
