Not sure what was added to the Voro water (or beer) but for about 36 hours, the boys are horny like there is no tomorrow. Friday, Lex fucked Iris twice and, after Iris was asleep, he jurked off in the bed next to her. For Nick, he fucked Lisa Friday morning, got a blow job before going to bed. When he woke up saturday, Lisa was not there so he used his best hand twice within an hour. and they were both horny on the couch for several hours. Nice to be young (yeah I admit it, I'm jealous:))
I repeat myself but I still believe that as part of the training program, they should force Sophia to watch Voro at least 4 hours per day. As Nick and Lisa are rather good to vary with innovative positions, might give Sophia some ideas. It would also show them that walking totally or partially naked in a voyeur apartment is good for business
