Gabriela, a temptress in glasses and a conservative dress, finds herself alone with a naughty surprise - a suction-cup dildo, a challenge from a student. She checks the time, then locks the door, her pussy throbbing with forbidden excitement. The dildo's every detail, from its veined shaft to its realistic head, makes her lick her lips. She removes her panties, and with a whimper, guides the toy inside her wet, needy cunt. She grinds against it, her nipples hardening under her clothing, until she's a panting mess, her orgasm ripping through her as she bites her lip to silence her cries.
