You apologize.

"I... I'm sorry," you blurt out after breaking your kiss with Samantha.

She smiles with tired eyes at you. "For what?"

"I came in you," you reply, looking away in shame despite the fact your semi-flaccid cock is still deeply embedded in her pussy.

"There's nothing to apologize," she smiles reassuringly. "You made me cum more times than I could remember. You're an amazing lover!"

"Lover?" you mutter, wondering how fast things have gone.

"I mean, we're more than just roommates who have sex?"

"I... Yes, we are," you reply. During the hours of sex with breaks to rehydrate, the two of you chatted to get to know each other more. The sex was the best either of you have had because you not only were attracted to each other but also cared. There were genuine emotion and tenderness behind the caresses, kisses, and fucking.

"Good," she kisses you. "I'll go to the pharmacy later to get some morning-after pills. Until then let's fuck again!" She squeezes her pussy muscle around your cock.

You guess her insatiable appetite for cock was from years of being in a relationship with a lesbian. You're glad it's your cock that she hungers for!
