I walked in on my boyfriend bent over and moaning while his lover was going to town. I got on knees and started ducking my boyfriends dick. I asked him who fucked him better me or his lover. Through moans he said that his lover fucked him better. I told him that I was glad to hear that and make him breed his ass. Within minutes my boyfriend was ready to come. He asked his lover if he could cum yet. His lover said he couldn't cum until he (his lover) was bred his ass. I told him (my boyfriend) that he needed to listen to his lover and make him cum. My boyfriend pushed back harder with each thrust and begged his lover to breed his ass. Within minutes his lover started grunted as my boyfriend begged to cum. Again, his lover told him he had to wait. Then his lover grabbed his hips and said he was going to breed his ass then shot his hot load deep into his ass. Just then I deep throated my boyfriend's dick and he started cumming as he said "Yes daddy, breed me! Breed my ass!". It was sexy as hell.
There have been a few times that my boyfriend and I have been fucking when his lover came in. My boyfriend knows to immediately stop fucking me and take care of daddy. It doesn't bother me and I get turned on hearing their moaning. I usually will just give them their own time.
