My First Cum Shower

My first girlfriend was a bit of a sadist, so on our first date, I started kissing her passionately and unconsciously rubbing her ass, but it didn't just satisfy my kink. I then licked her nipples and stuck my finger straight into her butthole, to which she screamed. Turns out, she was wearing a buttplug, and I knew she would love to be kinked. I carefully brought out that buttplug, she was embarrassed and smiled in a taunting way, and I said, "Can I just do whatever I want?" She asked, "You want to put your finger here?" Without replying her, I did it...she was groaning like crazy...it was such a warm and large hole.
She began to caress and suck my dick, and she was shocked to find that I had a decent amount of time (Genetically). And I finally had my urethral opening after about thirty-five minutes. She was so surprised that she yelled, "What happened to your hole?"
I was enjoying the immense pleasure, but I was also a little humiliated. My girlfriend was completely numb to witness someone cumming in this manner when my pre-cum started. I was groaning when she suddenly grabbed my balls and began to cum as her tongue teased my dick entrance. It was so big and thick that she was both frightened and delighted since it was so crazy.I was groaning like a lunatic, and my sperm was splitting like a shower. She started mocking me with a smile, which made me even more hot. She squized my balls so tight, and the feeling was exhilarating. She was washed, smiling and amazed, and asked how you could come so far! Even more than I've seen in pornography!
