Mandy led Syd in a circuit around the room pointing out the various furnishings. Through a door in the rear wall, they entered a swimming pool room wi...h adjacent lockers, showers, whirlpool and large sauna. After exploring the facility, it was time to get down to work. Mandy ushered Syd to the stationary bicycle in the main room. ‘Let’s get a baseline on the real strength and flexibility in your legs.’ Syd climbed aboard the cycle while Mandy checked some gauges and settings.

They forgot about the bar, so a few slightly drunk onlookers got to watch as two teens, one in a rather revealing new bikini wiggled and played with each other, sometimes wrapping legs around waists, butt cracks visible, hands reaching down trunks, over butt cheeks, kissing underwater.

I know that you are getting impatient for me to take you deeper, but I am enjoying the teasing. Your grip on my face gets harder as I go down on you again, and suddenly your hips buck up. Your cock slides into the back of my throat. You ram up with your hips again and your cock gets embedded deep in my throat. I can hear you moan out in ecstasy. You loosen the grip on my face again and I. Shes going on about christmas being a hard time and how her k** makes it much easier (first I had heard of the k**) so know i'm thinking this cunt is going to get all soppy. Thne she says right lets do it, off to the bedroom. I head in, we have a bit of a kiss and I start to take off her clothes, she stops me asks for th elight to be turned off, ok i do it, try to take off her clothes again and no luck.At this point I thought fuck this and I stripped off, so I'm standing there naked and this.
