Our new house is finally quiet, and I'm settling into my home office when my blonde girlfriend creeps in, hungry for some mid-afternoon fun. She's dressed in a sexy little dress, and I can see her nipples hardening through the thin material. She locks the door behind her, straddles me in my chair, and grinds against my growing erection. I pull her dress up, revealing her bare pussy, and slide two fingers inside her, making her moan. She unzips my pants, takes out my cock, and guides it into her eager cunt, riding me hard and fast until we both come undone.
