Warn her that you're about to cum.
From Create Your Own Story
You slide in out of her wet box quickly as she rocks her hips atop you. Momentum building, you cry out. "I'm going to cum!"
With that, Cassandra pulls herself free of you, then quickly drops to her knees. Before you can say a word, she has your cock in her mouth, sucking hard at you while her hands reach up to fondle your balls. You fire a thick salvo of seed deep into her mouth, and she swallows every drop. You spit shot after shot of cum into her mouth, and she swallows it all, then sucks you completely clean afterwards.
Trying to catch your breath, she rises up and gives you a guilty look. "We really shouldn't have done this," she says, reaching down to cover her body with her arms. "We really shouldn't have. I'm married. This is wrong."
