Relying on the kindness of strangers

You're still standing by the ice cream stall, waiting for inspiration to strike, when a customer stops to talk to you.

"Everything okay?"

He's a rotund middle-aged man, or rather ****, his collar set to red. You try to look him in the eye, but can't help noticing that the purple flesh of his penis is bulging out between the bars of an unfeasibly tiny cock cage, not much more than an inch in length. To be fair, he's also checking you out, a lot less circumspectly.

"My mistress wants an ice cream, but I can't pay for it," you explain, not expecting him to be able to help.

"I'll get it for you. What flavour?"

You could kiss him, but that would probably be unwise, so you settle for thanking him profusely and a few moments later, he's back with two tubs in hand, one for you and the other, presumably, for his own mistress.

"However can I thank you?"

"Us subs have to stick together." He winks. "Pay it forward, when you get the chance."

You both hurry away, he at a more sedate pace than you. When you get back to Diana, you're slightly out of breath, but you don't want the ice cream to melt on the way. She puts her book down and tuts disapprovingly.

"You certainly took your time," she complains (completely unfairly, in your opinion), then demands your flip-flops, which you hand over with alacrity, to find the hot sand extremely uncomfortable on bare skin. "Foot!"

You turn and raise your leg to give her access to your sole, which she slaps five times with your footwear, sharply. It really stings and you suck in your breath through your teeth. Then you swap for five on the other foot.

"Now get down here," she instructs, pointing, "I don't want my feet in the sand."

Currently having your own soles scorched by the burning grains, you don't blame her and quickly stretch yourself on your back under her feet. She lowers them immediately, one bare heel on your nipple and the other on your tummy, then squirts a generous amount of sunscreen between the two. Leaning back in her chair, she finally gets around to savouring the ice cream you got for her, whilst using her feet to rub in the lotion.

A few grains of sand make the operation more scratchy than erotic, especially when she clumsily works over your face. You screw your eyes shut, which a little giggle tells you amuses your mistress, then she carries on to your arms and torso, culminating with your genitals. Okay, that is a bit erotic. Just when you feel yourself getting slightly wet from the treatment, she splodges some more sunscreen on your thighs and rubs that in, before giving you permission to finish your lower legs yourself.

It's an unorthodox way to apply sun protection, but it seems to be working. You feel a marked contrast between the front of your body cooled by the air on your completely exposed privates and your back, trapped against the baking sand. Some minutes pass and the weight of Diana’s feet is starting to get uncomfortable when an unfamiliar voice comes from close by.

"I like your beach mat," says a woman in her thirties. "It's very pretty."

"Thank-you," replies your mistress. "Feel free to share it. Your **** too, if he'd like."

It's only then that you notice the younger man standing behind her, in a collar.

"What do you think, Timmy? Would you like putting your feet on a young woman?"

"Uh, n-no, mistress," he responds, with a tinge of fear in his voice you're normally used to hearing only from females.

"His mouth says no, but his willy says yes," Diana observes, wickedly.

"Oh, he's always like that," the woman interjects. "It's quite a chore, really."

"If you'd like Jenna to take care of it for you, just say the word." You're not sure whether your girlfriend is serious about offering your sexual services to a stranger, but you can feel your skin, already pink from the sun, darkening in a deep blush.

"That's an idea. It would save me the trouble. Has she ever sucked a cock before?"

"Oh, yes. She's a bit bi."

"Oh." The other woman seems disappointed, as though she would have preferred having a lesbian go down on her ****. "Well, if he earns a reward, I'll let you know. I'm Miss Paine, by the way. No, really."

The mistresses exchange details and then Miss Paine takes Timmy for a turn on a paddleboard. Diana shifts her feet so one heel is pressing down right over your clit and leans back to relax. It's very peaceful, apart from the occasional scream of a well-punished ****. You try to concentrate on your breathing, ignoring the growing discomfort from the sand, sun and your girlfriend's weight on your intimate parts. Just when you think you're going to have to shift position to avoid cramp, she tosses down her paperback, stands up and kicks you playfully in the side.

"Come along, lazybones. We have things to do."
