We were all exhausted from all our fun and were in need of some rest. Both of our gf's quickly got in the house as me and my coworker started to unloa... our stuff. The girls sat in the Livingroom with their phones and after about 10 minutes, they both knocked out. We finished unloading both of us sweaty and we decided to go ahead and take a shower before joining them on the couch. My coworker went ahead and headed into the shower first as I went onto check that the girls really weren't getting. He began thrusting, as hard as he could right away. He had his hands on my butt, and both of us were emotionally exhausted by then. I know we were both tired, but horny as hell at the same time. So of course, us being horny won. He spanked me like mad. It hurt a bit, but it was my son spanking me, so I liked it a whole lot.“Oh yes, Travis. Your mom has been a bad old lady, you need to teach me a hard lesson,” I said as I grinned.Then he laughed a bit, and began spanking me as hard as he could.. ” I opened my mouth and he slowly inserted his cock till I felt it hit the back of my throat. He continued to press it further and I began to gag. He withdrew a short distance, and said, “Just relax and try to relax your throat.” I tried to relax as much as possible, and he again pressed forward, and I felt his cock enter my throat. He then began fucking in and out each time plunging his cock deeper into my throat. I was gagging at first, but soon overcoming my gag reflex. I heard him moaning. “Yes ma’am. I’ll tell her you and I’ve met and that you’d like them to come over, my dad is off this weekend, so I’ll try real hard to get them to come over.” Brandy told Mom.“Mom, Brandy, I have to go. I’m so glad that you came over Brandy, and I apologize for not inviting you myself.” I told them.“Rick, I didn’t give you a chance to invite me, and I wasn’t going to give you a chance to flirt with those cheerleaders either without seeing me first.” Brandy laughed.I kissed Brandy on the cheek.
