"Ama, no!" Hema gasps, caught red-handed by her stepbrother. Her face flushes, but her body betrays her, nipples hardening beneath her modest clothing. Ama, his uncut cock straining against his jeans, can't tear his eyes away from his sister's fingers, now glistening with her juices. "You shouldn't be doing that, Hema," he says, his voice hoarse with desire. "But if you must, let me... help you." With a tentative step forward, he reaches out, offering to replace her fingers with his own, his fat, long cock throbbing with anticipation.
