My husband and I have a game we play at big parties. First off we love hosting big parties at our house. We love bringing our friend groups together have the space for it in the summer. During our parties we play a game where I make sure he sees me sneaking upstairs and I go to our bedroom put on a blindfold and wait for him. He sneaks away when he can comes up fucks me and goes back down stairs then I follow him after a few minutes. I love walking around having just been fucked knowing my husband is happy with his balls being a little lighter. So this one time this summer I go upstairs and after about five minutes I hear the door open and close and then I can feel his body heat against my skin but not doing anything so I wiggled and said hurry up. He played with my ass cheeks for a bit which was also not normal for this game then rubbed his head into my pussy. As he was doing that I couldn't hold back and pushed myself back onto him. I thought how he must be extra turned on because he felt a little bigger than normal he has a nice dick that sometimes leaves me sore but he felt thicker that night. Not longer just thicker. I started fucking him like a normally do. I love being a good girl doing all the work for him and jerking his dick off with my pussy. Since we have to use condoms I feel bad about that so I always make it extra special by twerking my nice ass for him. He came quicker than normal and I soon found out it was because he didn't put on a condom. I was a little mad as this was now the first time he had ever cum inside me and it wasn't special it was this naughty trick. I was glad he was happy though and said okay tricky sir get out of here. He left when I heard the door close I got up fixed my dress waited a few minutes and went downstairs. I walked around doing a lap checking in with all our guests floating on air with cum inside me for the first time. When I finally saw my husband I walked up behind him and whispered in his ear how he was a bad boy for tricking me like that and cumming inside me for the first without permission. He turned around with a shocked look on his face and said what are you talking about. I told him just now upstairs you fucked me without a condom and came inside me. He told me he wasn't able to get upstairs. One of our guests spilled wine on the carpet and he was cleaning it up. I said honey I just got fucked upstairs for five minutes and he came inside me. I felt like I was going to throw up. He said I don't know what to do. I ran to the bathroom upstairs pushed as much as I could out of me but very little came out. I cried and threw up. The next day I bought the morning after pill. I told my husband how the man felt thicker than him and I was ashamed for liking it and cumming in his cock. My husband said it was okay it was a mistake.
