After his suspicions were cleared, the boyfriend realized that his girlfriend was lonely due to the long-distance relationship, and began to think about cherishing their limited time together... A long-distance couple burns each other with passion! After a fierce thrust, the condom breaks and he tries to replace it, but she takes it off and inserts it...!?
