I walked in on my bf bent over being fucked. I smiled and got on my knees to suck his dick. I asked who fucked him better me or his lover? He moaned his lover. I said "Good. Now make him breed your tight ass babe." Within minutes his lover had shot his nut deep in his ass and I was swallowing my bf's nut. They kept going with his lover sucking his cock and then my bf slipping into his ass. I sucked his lovers dick and again within minutes my bf was nutting in his lovers ass and I was swallowing his lovers nut. I thanked them both for allowing me to be apart of it and left the room. They kept going. I would occasionally hear "Yes daddy!" or "fuck my tight ass daddy!" or "I'm your sissy boy daddy!". It was so sexy hearing them pleasure each other for hours. Anytime his lover is over I let them have their time because there's no need for me to be in there unless they ask.
