The ones you were eying.

You turn around quickly, hard dick hits your legs with a "FAP". You are greeted by the three you were aroused by. They were all clad in towels, dry.
"Oh no, please, continue. You seemed like you were really liking that." One of the twins was saying.
"How could you tell? It wasn't that long of a touch." you say hiding your eyes. She laughs at this.
"Wasn't a long touch? We have been watching you for a good five minutes!" You blush, it couldn't have been that long of a touch. Suddenly your thoughts are interrupted by the same voice. "Well, could we help?"
Only the black haired woman walks over. She gives a soft kiss as she grabs your cock. She pulls away, pulling you by the cock, she says, "Come, follow me." you have no real choice. Well, **** that you would rather do. They lead you to a small bench by the lockers. The black haired woman softly pushes you down. You end up on your back, neck craning to see the trio let their towels fall.
You get a good look at their bodies before they move to positions. The black haired one, who is at your head, produced a bottle of lube. She leans over you, her smaller erect dick centimeters away from your face. You think of sucking it before you feel a cool liquid fall down your shaft. A warmer hand spreads it around. You hear small slurping and suckling sounds, you suspect the twin with the smaller dick is sucking the larger one's. Only when the pale beauty leans up do you see it is the big dicked girl sucking and slobbering over her smaller cock. Clearly, she is trying to lube her up.
The girl pops out of her mouth and the bigger twin walks over to your side and steps over. Her ass hovering over your lubed up cock. Quickly she falls on you. You penetrated her violently, but she moans, so you suppose she likes it. The suddenness of it all forces you to moan, only to have your mouth filled by the woman behind you. Instinctively you start sucking, making the pale girl moan.
The bigger twin starts hopping up and down, slapping her cock on your stomach with every jump. Each thump leaves a dab of precum on your naval. You feel two wet fingers at your ass. It enters easily so the woman enters another, realizing you are loose enough she just withdraws and replaces it with her less-impressive cock.
In a symphony of feelings you are surprised when you feel hot liquid enter your mouth. You quickly realize the pale girl came as she moaned. You purse your lips trying to get as much cum as you can. You are interrupted by the feeling of cum against your freshly cleaned tits. You reach up and grab her cock as it shoots cum. All the while her ass is tightening around your cock, ring you to get more pleasure and soon cum.
You feel yourself empty into the twin, while your body does the same to the smaller twin and she does the same to you. Cum fills your hole and you love it.
