From Chrystal Heights:

Shari’s been studying magic and she decided she was ready to take over a warlock. Bad idea. The warlock had a complex ward in place and Shari found her spell reflected back onto her with the 3x3x3 rule in place. Shari is now bound by her own spell to provide oral satisfaction for the warlock 27 times. Cheeks red, belly full, her mouth helplessly stroking over the warlock’s cock, Shari is realizing she isn’t quite as ready for the big leagues as she thought.
