Have the swim coach pose

"Can you do a pose for us?" you ask boldly.

The woman snorts, but she turns around and rests her knee on the bench, striking a coquettish pose with her rear end pointed at you... the blue one piece gives pretty good butt coverage, but it's tight and beautiful.

"Perfect," you say, and pull out your cock. Blushing, Riley mimics you.

The woman isn't as bored as she wants you to think... her eyes are glued to your cocks.

Riley's cute... you see her slow down several times, trying to last longer. You decide to show her some mercy. You will cum first so she can let go.

You move a bit closer to the woman and speed up, your strokes sounding squishy now that your cock is covered in precum. You concentrate and take careful aim, stringing a sticky rope across her beautiful buttock, then pumping out the rest at her lower back so it collects and dribbles down the crack, the white standing out blatantly on the blue of her suit.

Riley whimpers and shoots, getting a little on the swim coach's other buttcheek, but mostly spurting it on her thigh.

"You good?" the coach asks, watching you two catch your breath.

"Great," you reply. Riley, face red, nods.

"Good. Get out of here."
