So #3 you sir are one sick bastard! I took your advice and I've been making comments about my gf while fucking my mom for over a month. It started out like "man your tits are bigger than Shelly's" and "maybe Shelly needs a shower buddy too" or "I wish you'd give Shelly lessons on sucking cock". I finally worked up to telling her "I'd love fucking the two of you together", "I bet Shelly would love to feel your big tits all over her face", "Do you think your tits would rub on Shelly's if I fucked you on top of her" and finally I just told her "I want to fuck both of you together" and "I want to see you fuck Shelly with your shower buddy".

All the time she didn't let on, but she got worked up a lot faster when I talked about my gf while I was with her, until I told her I wanted to see her fucking Shelly with her shower buddy. She really went wild. I kept at her with "I know you want to climb on her and fuck her", "You want to push her on the bed and fuck her don't you", and "I've heard she's bi, so she'd take your shower buddy any way you want to do her with it". After a few days of fucking like this, she said, "Yes, I've always wanted to fuck her."

Sunday was the day! Shelly and I spent the day together. I kept feeling her up and talking sex, I do both of those a lot any way, but made sure we were not alone. She was getting ready to suck me in the automotive section at Walmart, but some guy kept coming around. I think he knew what was up and wanted to watch or hoped he'd get some too.

We got back and went to my room. Shelly instantly jumped on me and we wrestled around on the bed stripping each other. She climbed on and I shot my load into her. I let my cock fall out of her and I started rubbing her, she kept humping frantically. She was nearing an orgasm when I saw mom sneak in. She was wearing her shower buddy, it looked like a giant dick hanging from her. A fucking strange, but erotic sight to see her big tits and a dick hanging down like that.

She climbed on the bed and slid it into my gf. I wish I had a video of the look on my gf face. Her eyes just about popped out and she started squealing. I felt her start her orgasm as she fell forward onto me. Mom leaned into it and started fucking Shelly like crazy. I shot another load as Shelly rubbed across my cock from getting pounded from behind. I could tell Shelly's orgasm was winding down, so I pushed them off of me.

Mom pounced on Shelly as I got out of the bed, and I watched them fucking for well over an hour. Seeing my gf c**t laid open by that huge shower buddy, I thought there would be no way Shelly would ever be tight around my cock again, but seeing her and my mom fucking was well worth it. I shot all over the floor two more times watching. Shelly started to squeal again and mom lunged forward onto her and started kissing her. She was squealing into her mouth as she ground that big rubber cock into my gf.

We all spend the rest of the night in my mom's king sized bed. I asked Shelly to move in, she's thinking about it.
