Spring Break Susie [EPUB ebook] 

Her study time is interrupted by their hard, rough chemistry lesson!
Susie thought the best part of her spring break would be having the library all to herself. Then four guys and the security guard shows up to teach her more than books ever could about hot, raw chemistry—and she teaches them a thing or two herself.
An erotic short featuring multipartner, strangers, DP with rear entry fun.
