That's when I like to stick my dick in lol Me and my gf do the occasional MMF creampie party. There's nothing hotter than going to have sex with your girl and watching another guys load drip out and all over the lips as you're about to stick it. I like for her to ride on top so it drips down my shaft and off my balls. She wants to try it with 3+ guys now. We have only ever done threesomes. One time during a foursome with one of her friends, since she was the only one on BC, we agreed to let him finish in her. He was having sex with is gf and right when he was about to cum, he quickly jumped over. I had to take out my penis quickly since me and my gf were having sex, he put his in and came. Then when he was done me and my gf went back to having sex.
My gf is really tight so it helps with the lube if she's already taken a load inside her. I prefer it too. After I cum though, her V and my package are just covered in all of our cum. We do this often and BC working great! There are only 2 ppl we have threesomes with but they are both heavy cummers. We fill her up nice and deep, every last drop, all the way, everytime, until our sacks are dry. She leaks for hours after were done. She also enjoys making out with me while getting filled up so the other guy tells us when he's about dump his load and we make out.
