Aspen Brock is a late learner where cocksucking is concerned
Aspen Brock believes whole heartedly that if you fuck a man well enough you can drain his power from his cock and direct it into your womb to be stored for later use at your discretion. So her plan is to get Trevor Slide and Johnny Thrust to fuck her in ways she's never tried before until they're so totally spent that she'll have all their power inside of her and she'll be able to use it whenever she wants. Neither of the guys have any clue what weird esoteric stuff she has planned, they just want to fuck.
