That smirk? She’s been doing this since he was in diapers. First, her lips seal around the head of his cock—slow, deliberate swallows while her fingers dig into his thighs. Then the train lurches and she laughs, pulling back just enough to say ‘Hold on’ before swinging a leg over him. Reverse cowgirl on moving metal: tits bouncing against her chest, nails scraping leather as she rides him like it’s payday. No finesse—just raw experience. Cum hits the back of her throat and she swallows without breaking eye contact.
