Training for Deep Throating with a 19 Cm Banana

I was doing deep throat training with a 19 cm banana. My boyfriend was teaching me how to deep throat. I started slowly, first with 10 cm, then increased to 14 cm, and finally managed to swallow 18 cm! I want to try 22 cm. By the end of the session, my boyfriend ejaculated in my mouth, and I swallowed all the sperm.
