Tony didn't get instant gratification for his efforts, he follows the girls and learns that they were both pretty turned on by his display. As Tony watches, the girls slip their hands beneath their graduation gowns to touch themselves while reminiscing about Tony's nice dick. Tony can't help himself; he comes up and lends Hime a hand while she assumes that it's Lulu touching her snatch. When Hime realizes it's really her stepbrother, she hesitates initially, but with Tony and Lulu both urging her on Hime agrees that they should all fuck.
