I spent the rest of that Sunday with Jim and Becky.
It took us a while to recover from the first session, though.
I put the dildo on the bedside table when Jim fixed me yet another drink. He hadn't had an orgasm yet but he seemed happy enough to wait his turn. Becky lounged around on the double bed, she partially covered her nakedness with a sheet but there was ample opportunity for me to study those breasts and her long legs.
I put my shorts back on and relaxed into the armchair.
Jim kept talking. He briefly recounted the night the girls had taken turns with the strap on. He had fucked them as well. He casually rubbed the bulge in his pants during this conversation. He gave me plenty of detail about the girl's bodies and I wondered if he enjoyed the watching more than the actual sex.
Becky rolled onto her stomach, exposing her buttocks. Jim moved onto the bed next to her.
"So Jane didn't tell you anything about our hobby?"
"No. I'm amazed. I knew that she used to be a bit, er, friendly. We had discussed this sort of thing but it was all hypothetical. Until last night."
Jim was massaging his wife's bum. He ran his hands up and down her thighs. She moved her legs slightly, allowing him better access.
"So, you and Jane have fucked a few times, then?" I wanted to know, I had some catching up to do and I wanted to know how much.
"Oh, yeh, a few times. Mostly in here, but once in the yard and once in your house. He slipped a finger into Becky's anus. I saw her butt cheeks twitch in response. "There were a few blow jobs, at first, but now she saves them for you. Your Saturday Night Special in the hallway, eh?"
