Time to get back to the house.

You pull your cock out and wipe it on the back of her thighs then give her ass a spank, unintentionally hitting her clit and causing her to climax again. You flick the back of her dress back down knowing that itll stick to your cum on the back of her legs. "We better get back before they send the search parties out for us" you say. She rolls over and tries to get up but from all the orgasms her legs are dead, you have her put her arms around your neck and pull her up, with her dishevelled face looking at you you give her a passionate kiss and tell her "wow that was amazing Jane, you have an incredible body and the best perky chest and your pussy felt amazing, not many girls... women can take me fully in mouth, pussy and ass, Jack is a lucky man and im honoured to be your second lover". She looks you in the eye and gives you a quick peck on the lips then says "you need to never tell anyone about this, Jack would not be happy, we have an open marriage agreement but neither of us have ever used that, we just thought it would be hot having the idea of it.", you agree to keep the secret as Jack is one of your closest friends, but you ask her "if you didnt plan to go this far why dont you have any panties on?", she explains that earlier in the night Jack had started to finger her in the corridor through her panties and he had asked her to remove them for the rest of the night as they were gonna fuck later, whilst the party was still going on, the risk of being caught was the ultimate aphrodisiac, but after she took them off and went to find them he had passed out on the couch. Which left her extremely horny. You understand and she is then able to walk again so you continue to support her and you find the dog and almost carry Jane back to the house. She is staggering and you ask if shes ok, she explains that her pussy is quite sore from your session, as is her ass. You make it back to the house and everyone except Jack and Jessica has left. Jack is still passed out on the couch but Jessica has unzipped his trousers and is sucking on his cock, she hasn't heard you both coming in as she is facing away from the door.
