Tentacle Breeding the Schoolgirl (Monster Sex Triple Penetration Erotica) by Kat Shields
Amanda is in her room fuming, feeling like she doesn't have a life of her own. Up in the attic, an alien monster and its slimy tentacles are ready to make a move on her. The monster has watched her grow up, and now as she sits on her bed lonely and ovulating, it slithers in, preparing to brutally inseminate her.

"Amanda didn't even notice her closet door behind her was pushed open by a mysterious force. She was too busy touching herself to realize that a giant, slimy and colorful tentacle was beginning to emerge, shaking like a snake's tail. It was about to grab her."
"Amanda no longer felt like a person anymore, she felt like she belonged to them, and had no right to reject their presence. She was doing her best to control her mucles and thrust herself in the air against it. That was when she felt a cold and thick sensation cumming inside of her."
"The alien was way too dominant for her not to submit to it sexually, just as she would if it were an alpha male on a motorcycle, she had no choice but to breed with the godly being, mixing it with her puny human genetics. As a fertile girl, she couldn't respect herself if she didn't."
