You decided to approach the hot red Pegasus. You were already behind them as they lied down, so you approached the red one's sizable rear, and she seemed to take notice of that. She grinned and shifted a little, her butt wobbling a little.
"Thanks for showing up, darling," she said. "We heard good things about your technique! My poor rump's been awfully sore. Can you get on that?" Oh dear, this old request. Then again, they were kind of... bigger than you were used to... Either way, you were in the thick of it now. You approached her backside and reached beside the table she was lying on. You pulled out a vial of massage oil and slathered it onto your hands. You stretched a little and cracked your knuckles, before approaching.
Your cheeks lit up with embarrassment as your hands descended upon either cheek. And then you began squeezing. She lightly sighed and laid her hands on her arms, her tail lightly swishing. She seemed well behaved compared to the usual client. Often times someone got you to rub back here, that usually resulted in some squishing or you forced to smell some stink. Not helping matters was the fact that masseuses had to massage for either a specific amount of time or until the client says otherwise. Those that don't follow this rule get punished... Right now, the only annoying thing was the Sirens' tail lightly tickling your abdomen. Sure, it was pretty embarrassing to be touching someone like this, but things could be worse.
Unfortunately, you didn't notice her legs lifting up ominously behind you. Suddenly, they snapped around your hips and you were yanked forwards. You let out an eep as you felt your hips beat against her booty... and your crotch rub in between her buttocks. For a moment, you lifted your hands up in the air, grasping at air as if trying to find something to grip onto. But all there was was tons of butt in front of you... tons of butt threatening to swallow up your most private of parts should you let it rise. You tried to step back, but you felt the Siren's thighs pull tighter.
"Now now, dear, I'm not quite satisfied, yet~" she said. Her thighs moved in such a way to rub your groin up against her backside, your little body squirming against her big butt. "And I know you guys are supposed to satisfy your clients~ So please, continue." Nobody had done something like this to you before... You felt yourself threatening to plunge your organ into her, which caused your whole body to quiver. You wanted to step away, but right now you had a duty... Could you afford to keep rubbing? Or do you think you can whether any punishment?
