Cucked at a Halloween costume party [cucks prospective]

My wife and I decided to dress up and go to a Halloween party this year just to add a little spice to our life. She kept telling me it would be so cute to do a couples costume so my wife and I went as woody and bo peep from toy Story. Come to find out my friend also decided to go unbeknownst to me. So my wife and I show up at this party and are having a good time when we spot my friend he’s dressed as Gerald from Hey Arnold. My wife and I spot him and call him over to compliment his costume he fits the character perfectly he compliments mine and my wife’s but seems to linger on her a little longer but I chock it up to my being a little intoxicated. As we are all enjoying the party I noticed my friend keeps getting us drinks but he isn’t drinking so I asked if he would mind being our designated driver he said sure no problem you know I love you guys. We’ll around 11 we are completely drunk me more so than my wife so she decides we should probably head home and I reluctantly agree. By the time we made it home I wasn’t able to keep my head up my friend helps me inside the house and I instantly get sick he helps carry me to the bathroom. Between bouts of consciousness and vomit I tell him how much I appreciate him being such a good friend then I go back to hugging the toilet. I come to as im being shook awake in my bed still fully in costume as I look to my right I see my wife still in her bo peep costume my eyes still foggy but I can hear muffled moans. She opens her eyes about the same time as my vision clears up and I see her mouth wide agape stifling a scream my eyes look up from her face and I can see my friend behind her plowing into her with long hard strokes. I try to stammer out a protest but its useless my throat is hoarse and dry from all the vomit. My wife notices me looking at her and him as she screams in pleasure and he blows out im that he is filling g my wife’s tight pussy full of his cum. As a smile creeps across her face both post orgasm him still firmly embedded in her she say dead pan you got a friend in me.
