<<little known fact>>
Real hardcore lesbian women (not the hoes you see in porn)'s vaginas are lined with many rows of small razor-sharp teeth. When a douchey guy with no respect for personal space (most guys are not this douchey) tries to enter the cavity with his penis, the teeth will clamp down on his now helpless member and rip it to shreds and spit it out.
Jake: (laughs) You knew she was lesbian, right.
Douche: C'mon. I could tell she wanted my cock.
Jake: You're a sad excuse for a man.
Sarah loves pussies and is a lesbian.
