I wanted more, but was pretty sure that she wouldn't let me fuck her again. I thought that she might let me nurse her boobs a little bit more, so I e...gerly started sucking on them again, savoring every sweet drop. It wasn't long, and my wife was massaging my cock, getting me hard again. I knew that this day was going to be one to remember. I knew I'd get it at least one more time.This time, I spent more time sucking my wife's breasts, and licking her pussy. Finally, I'd settled down enough. “Oh really Becky, what did you get him to explore…?”I am beet red now and sweating like a pig before breakfast on slaughter day…“I think he should tell you two, Honey…”“Hey Sis and Mandy…how you two doing?”Sis says, “Quit stalling, out with it Mr…what did you explore??”I figure best to just rip the band-aid off without pussy footing around, right?“Well…the Doc with Becky…he is bi and he and I sucked each other’s cocks tonight…” I brace for impact again and wince after I say it….Mandy speaks up. He bit his bottom lip as he felt pressure against his ass hole and his cock twitched painfully. “Oh, please, Mistress,” he begged, “I am so weak. I am afraid to disappoint you, Mistress.” “You won’t,” she laughed in reply. Suddenly the dull pressure against his ass hole turned to sharp pain as a 7 inch dildo penetrated him to the hilt. He screamed and tried to move away but couldn’t since he was bound to the post. When the initial pain subsided he felt unbelievable pleasure as the dildo pressed. I opened my eyes and reached out to her, grabbing her hips and gently thrusting in time to her rocking. She immediately had another orgasm, and then stopped. “Don’t you dare cum,” she said softly, paused for a minute, then rolled off. She pulled the covers back over us, snuggled up and whispered, “Please, don’t cum. Promise?” “Okay, but wha…” “Shush. I’ll explain in the morning. Now go back to sleep.” So I did; quite fitfully as I was sporting a huge pair of blue balls now, but I did. I.
