They still had a standing appointment once a week for a pleasant round of sex even though-officially-they weren't supposed to be fucking unless it was with Sondra.
Even though she knew that Evan couldn't get her pregnant she still desired his body on a regular basis. It was pure recreational sex without all the annoyances that Henry brought. Sondra grinned at her. "I came to get laid, if that's okay with you.""Um." Her mind raced. She had thought she was being discrete with Evan, but obviously Sondra knew about them. "I guess, " she said warily. Her hesitance made Sondra equally wary.
"Is there a problem? Is your girlfriend home?"Rebecca shook her head. "No, no. I was uh.just trying to figure out if I've caused some stupid problem or not.""Because you're sleeping with Evan behind my back?" Sondra prompted."Um.yeah, that, " she said and opened the door wider to admit Sondra. "You knew about that?" she asked as Sondra stepped inside. The older woman nodded and looked around the house's small living room.
"Did you catch Evan in a lie?"Sondra shook her head now. "No. He's too smart for that, but he also has a very guilty conscious too. He confessed. But I had already guessed.""You had?"Sondra finished her quick assessment of the living room and slipped off her light jacket. "Yes, I had. He wasn't asking for sex from me nearly as much as he used too and he was talking about you too much. It wasn't hard to figure it out." She sighed and looked down at her body, a view that was partially obscured by her large breasts.
"If I were a man I'd rather have sex with you instead of having to make do with this body, " she said. "Wouldn't you?"
