Continue kissing

The sensation of her soft, virgin lips against yours is too precious a moment though, and you continue to kiss her, her hands rising to either side of your head as your tongues entwine. She begins to moan, and the sensation is otherworldly. Your prick hardens as she bucks beneath you, your groin's rubbing up against one another.

Her moans rise in pitch and...

A knock at the door.

You both startle, almost crashing heads against each other in your haste to extricate yourselves from one another. You both stand, straightening your clothes as you redress, looking from the door to each other in rapid succession.

You clear an errant hair from across her forehead and head over to the door, subtly unbolting the door so as not to allow whoever is on the other side the knowledge that the door was locked, and throw it open.
