So my ex who happens to be my GF's best friend, had to move back to Iowa to help her sister. I went over to her place with my gf to help her pack up and everything, and her sister ended up needing some Diapers and formula for the new baby, so I offered to go get it for her. Mary offered to come with me because she knows what brand Kelsey buys for the baby. So we went to Walmart in my SUV, and I Always keep a blanket and pillows in the back seat out of habit from when I lived in Iowa (if you get stranded in a blizzard and are buried, you want a way to keep warm) so when we got to Walmart, Mary told me to park on the far side of the parking lot. When I did she grabbed my crotch and kissed me. We ended up moving into the back and we fucked for almost an hour. She let me cum inside her and cleaned me off after. Then after we had gotten the stuff for the baby, she gave me roadhead and I came in her mouth. Later that night, I asked my girlfriend if she wanted to fuck, and I had her give me a blowjob. I had only ever been with one woman who could blow me to completion (my aforementioned ex) but the thought of my girlfriend sucking pussy juice of her best friend off of my cock made me blast my girlfriend in the face. I was still so fucking turned on, so I was still able to go and I pounded my girlfriend's pussy thinking of Mary's Pussy juice mixing with Kat's gave me stamina I didn't know I had and I filled her up a few times and when we were done there was a huge wet spot (my girlfriend is a huge squirter). Kat told that we haven't had sex like that since we first started fucking. The best thing is, I know Kat is going to tell Mary about this sex season (Kat tells Mary everything regarding our sex life, and Mary had come to me with issues that Kat has told her about so I've been able to learn and adapt) and Mary is smart enough to know why, but she won't be able to tell Kat
