Melissa packed her notebook in her bag and stood up.
"Are you coming, Erika?"
"Don't... Don't wait on me! I... I need to go home to change out of school uniform" stuttered Erika, "maybe check on Max as he's been alone all day. I'll drop by your house after that, if that's okay!"
"Sure, see you then" Melissa replied before leaning over, hugging her friend tightly.
Erika could actually feel the weight of Melissa's ample bossom over her own, and it made her canine penis throb under her clothes. She squeezed her bag closer against her body, which pushed her breasts futher's against Melissa's and accidentally popped a button from her shirt. Melissa didn't seem to notice, and after what seemed like an eternity she broke the embrace and exited the classroom .
Erika slowly stood up, still holding her bag against her belly with both arms. Her erect penis was pressed underneath, the skirt's waistband keeping it into place, and her shirt concealing it; some of her cleavage was showing where the button had popped. As she awkwardly walked out of the classroom, she could feel the wet spot spreading as the fabric rubbing added to her excitation.
She could go to the bathrooms right now to squeeze the goo out of her canine member and end this, but her problem would return sooner. It would probably be best to wait for the last minute before going to Melissa's, so she wouldn't be bothered too soon at her friend's place...
