My girlfriend sucks my cock while I suck my friend's cock

While my brunette girlfriend and I were in the sitting room talking, my friend dared her to give me and him a blowjob. After she sucked our cocks, I fucked her from behind while she continued to suck my friend's cock. I then sucked my friend's cock while my girlfriend sucked my cock. My girlfriend then sat on my friend's face while I fucked his ass.
