Open your mouth slightly, then use your tongue to lightly gauge the distance and depth.That sounded pretty enjoyable...It'll probably be even more pleasant with the mouth...Aaaah...I'm regretting it.Um...It was simply just a sense of jealousy, every time I bump into them.Then slowly suck on your partner's lips...like this.And use your tongue to gently lick the insides of your partner's mouth.Her compatibility is pretty high huh...I never thought it'll be something this pleasant...
