This is easy to answer. I will try to explain in few words as possible. If an hot eschort is welling to have shower sex with me to start, push me gently to the wall after (15min), stick their tongue done my throat playing tongue hockey, suck on my nipples, run their tongue down to my stomach, suck my dick standing up (10min) , then suck my dick on his knees than on the bed and lick and suck my balls maybe rimm(15 min) then romp with me in bed (10 min) then suck me off till I cum (10 min). I guess that service would be worth $350 or more to me. Hince, the $50 or more tip. The best part is that eschorts who charge less get a bigger tip.
