Petite girlfriend is cuckolded and falls into pleasure after being ridden by a giant senior's riding press

I got my first girlfriend. She's cute and kind and proud of her. I have no experience in love, so I can hold hands and kiss them... At that moment, he meets a famous senior who is badass. My senior violated my girlfriend. He was three times as much as her weight, and he was forced to cum over and over again, making her unable to move due to his size differences. This kind of sex made her fall in love with her senior and she was cheated on me before I had sex...
