Sarah's eagerness to perfect her cum-swallowing technique is evident as she devours Matt's giant cock. She takes him in deep, her mouth stretching around his thickness. Matt's hands tangle in her hair, guiding her pace. Sarah's eyes flutter as she fights back her gag reflex, her cheeks hollowing as she sucks him urgently. Matt's groans grow louder, his body tensing. Sarah pulls back, her tongue swirling around his tip, coaxing his hot cum onto her tongue. She swallows greedily, a trickle of cum escaping her lips as she leans back, proud of her accomplishment, her tits glistening with his spend.
