Vintage 3some on the waterbed

Two swinger wives were laying on the bed and giving their husbands a show. One of them started to lap up the pussy of the other woman while they laid on the waterbed. After she fingered and lapped up her pussy for a while, one of the men joined in and started eating her own pussy. Then the ladies switched places and more pussy eating commenced. The man joined in again to go down on one of the ladies, but they seemed like they were having a good enough time on their own that he backed off. Then the women were licking each others' hot twats at the same time as they laid in the 69 positions. After a few more minutes, one of the men joined in the action again as he fed his cock to one of the wives as the other one fondled his balls. He then plunged his hard erection into some pussy as he nailed her on the bed and the other woman sucked her perky nipples.
