As Jame was pretending to be Lisa taking a shower so that jack would not suspect that anything was out of the ordinary he hit one of Lisa's erogenous zones and as he was feeling the orgasm it gave him Jack had entered the shower and grabbed who he thought was Lisa. He turned her around quit fast and had his dick up in her before James know what was happening.
James tried to resist at first but the orgasm he just had along with the pumping of Jack dick in his new pussy, James found himself actively riding Jack's dick.
The two of them kept at it for over an hour (James did not know Jack had such stamina) with James having another two orgasms before Jack shot his loud up into her.
After jack had shot his loud he pulled out of Lisa but continued to work her body as he soaped her up.
After They were rinsed off but before they left the shower Jack and Lisa had another long kissing season.
When they were out of the shower and drying off Jack told Lisa "I'm glade your home the boss invited us up to his cottage for the weekend. This could mean that promotion I've been working for is a go so pack a bag and make sure you pack that sexy string bikini of yours, you know how the boss likes you in it.
James just stood there as Jack gave her another kiss and went into the bedroom.
What the hell am I going to do now James thought.
