A whole new Beast.

As Raven pondered what could happen, she realized that Beast Boy's cock was getting further into her mouth...and she wasn't moving forward. Beast Boy groaned.

"Wow, Raven...I...I feel kind of weird..." Raven looked up and almost choked. Beast Boy seemed to be shifting in slow motion. Fur was sprouting all over him...he was growing taller...beefier. He grunted. "Nngh...me horny..." He picked her up as his tranformation neared completion. Unlike his combat based Beast form, this one was more ape then wolf. He looked almost like a caveman...but hairier...and green. Before Raven could do anything, she found her back against the wall.

"B...Beast Boy, wait! I..." she started, both scared and aroused. Too late. He shoved himself into her. Raven cried out in pain at the sudden intrusion. "B...Beast Boy, stop! Y...you're...you're too...big..." Raven pleads faded as her pain faded away. Now all she felt was pleasure. "Oooh...oh, Beast Boy, fuck me!" Raven shouted as he plowed her hard. She rubbed her breasts against his furry chest, cooing in delight as the softness brushed her stiff nipples.

"Oh AZAR, this is the best f...form you've ever taken," she declared shortly before orgasm over took her. Beast Boy didn't let up, pounding away. "F...fuck! I...oh shit, I'm...I'm cumming again!" screamed Raven, not caring who heard. "You...you're making me cum again! Ohhhh Beast Boy! Ah! Ahh! AAAAH!" And it didn't stop there. Raven soon found herself blacking out.
