Luckily, Don dropped by for a "cameo appearance" as he calls it when he can escape from some social obligation only long enough to undress hastily, give Dee a sound fucking until he cums, and then make a quick retreat. (Not to worry - one climax for Don usually means about a half dozen for Dee when he's in her.) After watching Arnie paw at Dee for close to two and a half hours I'd had enough and fucked her hard, deep, and fast myself. The poor thing was craving cock in the worst way, and Arnie wasn't delivering. After I came, he resumed their sexual play, but whenever Dee's little toes went up with her legs wide apart and her juicy cunt glistening and her own hands rubbing her inner thighs in a blatant invitation to Arnie's very stiff dick, he made a bee line to kiss her, to feed her his cock, to slip a few fingers up into her steaming hole in what had become by the end of the evening obvious diversionary tactics.
The evening grew late. It would be time for us to head home soon. With one final, last ditch effort, Dee splayed out her bare bottom for Arnie and implored with a hissy, "Please!" for him to fuck her. He muttered something like, "But the husband's supposed to cum last," and in spite of having the same rock solid erection which he'd maintained for most of the evening, he left the bed and headed for his pile of clothes. Dee and I never did figure that one out. Had I crossed some unwritten rule of wife sharing by taking Dee when I did? Hardly. It wasn't as if Dee hadn't invited him inside her many times before I slid up into her. And it isn't as if we play by some set of rules ourselves. If it feels good, and nobody objects, do it is our usual credo.
Although there were a few other guys who declined Dee's offer for them to fuck her, they were soft swingers whose SO's didn't want them to do the full penetrative thing with her; that we can respect. An Arnie, though, is just a total mystery. In retrospect, he seemed to be little more than a major tit man who really didn't want more than to maul a set of soft boobs harder than his wife lets him go at hers.
