I allowed my soon to be son-in-law, Steve, to have his bachelor party at my house. I soon realized that I left him the wrong key to lock up the door if they went out to the bars. I tried to sneak into the house and switch out the keys. That’s when I heard him and his buddies talking in the other room, comparing dick sizes. I peaked in and It was pretty amusing and actually turned me on. 'Steve', was by far the biggest! Before I could sneak back out of the house, one of the guys caught me and pushed me into the room, mistaking me for the escort of the night. I really was shocked and did not have time to react, so I just went along with it and before I knew it the smallest one had his cock inside of me, while I was sucking off two of Steve's friends while my son-in-law, to be sat in a chair and watched, stroking his fat cock. The room was dimly lit and I don't think Steve recognized me and before I could leave he stood up and rammed his fat cock in my mouth before I could object. I wanted him and I loved that 4 guys wanted me and Steve was so hot and I needed to have him in me. I know he wanted me so I told him to lay down and I rode him reverse cowgirl until we both came hard. I scurried out of the house hoping he didn’t know who I was. When I got outside I got a text from him saying "thanks for the key! I hope you came hard mommy" :-O
