She knows when Daddy's about to cum to start massaging his balls. Then as he shoots and pulses, you keep stroking, sucking, and massaging, until he tells you to stop.
My hubby treated me to being put in my Cuckquean place tonight. He invited over his girlfriend and made me lick her clean. Which was my pleasure to do so, I love licking my hubby’s sticky cum off of his girlfriend’s hard nipples.
