In some ways, having his cock buried deep into his wife's wet cunt, it was just like regular sex with Abi.  But Robin's presence alone was enough to dial up the intensity, her thumb up his ass and her grip on his balls, well it was a whole new ball game.  "I love you too."  He said almost reflexively, a habit born of many years married to the same woman.  It wasn't that he didn't mean it, he did he just didn't need to really think about it.  But Xavier hadn't fucked Abi like this in years, if ever.  Each thrust into her was driven by not only his own passion and lust, but by Robin's rather mysterious but undeniable influence over him.  Everything about him said he shouldn't enjoy this sort of penetration, or any kind of penetration, he was a man after all.  But fuck it felt good and his cock throbbed inside of Abi's tight pussy.<br/><br/>Robin's position might be enough to make Abigail forget they had a guest, though Xavier's renewed vigor was likely a reminder.  But there was no way Xavier wasn't completely and utterly aware of the third wheel practically driving their relationship at this very moment.  Xavier thrust extra deep into Abi as Robin's thumb plumbed deeper into his ass, the full digit entering him as he groaned with pleasure.  Her words of encouragement were probably unnecessary, but they did remove any possible chance that he wouldn't blow his loud right then and there.<br/><br/>His ass gripped her thumb as if wanting to draw more into himself, he came hard as if Robin's grip on his balls had increased the pressure of his ejaculation as he sprayed deep into Abi's core.  His mind filled with the vision of Robin's boyish face lapping his cream out of Abi's still gaping pussy.  "Oh fuck yea."  He said, in response to her offer, he wasn't one to swear or even talk dirty during sex, but clearly things were different now.
