Alien SPERM CUMFLATION

Maxi is sitting down to continue writing her book. Everything is going well, until with a corner of her eye she sees a... flicker? She brushes it off and carries on. But it happens again... a green flicker. Again and again. It's really starting to mess with her head. Is it getting closer? She tries to type some words, but words don't make sense anymore... Poof! When she least expects it, the green light is now in front of her, jarring, blinding, covering everything with a shocking layer of green. She gasps... what can she do? A creature appears... it cannot be from this world. Just like that, Maxi can't control her body anymore. She panicks but she knows she can't do anything, the unknown figure will do as it pleases. It uses its alien penis to penetrate and fill her pussy to the brim. Just how much cum can there be? Just when she thinks she can't take any more sperm, the alien creature moves to her mouth, fucking it, stretching her cheeks, making her question her fear. Is she starting to enjoy it? No... no... she can't... The alien form cums buckets inside her throat and makes Maxi swallow! That doesn't mean anything good... Maxi's tummy starts to grow and expand beyond limits! She's terrified, starts touching it frantically, unable to mentally grasp what's happening. But the alien creature is not done. It slides its penis in her mouth again and fills it to the point there is no more room in her stomach. It starts overflowing and pouring out of her mouth. She's so filled with cum... she's gonna go POP!
