Trish doesn't notice

After several seconds had passed with Andrew fully inside of Trish, she said, with a quaver in her voice, "That's enough, right?" Her voice was barely above a whisper.
"I think that's fine," John said, smiling still. Hearing this, Andrew pulled out, but none of his cum followed him out. It had congealed at the entrance to Trish's womb.
"Good," she said, "but if anyone else gets anywhere near my pussy, they need a condom. I'm not about to have a fucking kid or anything."
Hearing this, Andrew's heart sank. "You're not on birth control?" he asked nervously.
"Of course not; why would a virgin need it?" she responded.
