Daughters erotic panties

Discovering my daughters sexy panties was more erotic than I'd anticipated. She's 20 and not sexually active, but I found her personal massage tool tucked behind her bed and could only imagine her playing with herself in her soft bed.
It started with the panties she shed in the bathroom before shower, and I noticed how lacy and feminine they looked. They were white lace with a pink border, wispy and so lovely. I took them in my hands and they were so soft, and the pattern felt good in my fingers. My cock thickened and I wanted to rub my hardening dick in those sexy panties that had recently cradled her young sex. Tentatively, I sniffed them and was rewarded with the delicious scent of pure vagina. My cock throbbed.
I took them into my room and lay back on the bed, opening the soft lacy crotch and watching my erect penis head rub from the front to the back of her beautiful curvy panties. I took out my phone and started filming, becoming more excited to see my throbbing dick folded into her most private places. I brought them up and inhaled her scent again, feeling my arousal build from the smell of youthful sex. As I stroked myself up and down in the divinely soft fabric, an enormous pleasure built in my cock and I slowly fucked those panties. Every pump build my passion as I watched my cock peek up through the heavenly material and then felt it engulf my head again, dragging pre cum from my head. I wrapped them fully around my ecstatic and groaned as I pumped strong spurts deep inside her panties, an amazingly satisfying orgasm. It was such a sublime feeling, both wrong and yet so hot.
