Rach and Rob invited us for a swim and BBQ. We’d been casual friends for about a year and began flirting and teasing with no more intimate contact than cheek kisses. Sue and I felt they were open for more, yet felt they held back, so we held back too. It might be nice to have some casual friends we didn’t fuck.

Sue and I put on swimsuits, since the sense was awkward, while they dared to keep just their underwear on. Their wet undies were provocative as they clung closely to great tits and stiff genitals. We didn’t succumb to their teasing to strip though we are typically the more assertive couple. I don’t know why we were both embarrassed to join in. Sue’s small tits were well contained in her bikini, but her stiff nipples made a deep impression on her top and Rob. I want to believe my tented short suit impressed Rach as well for future pursuit.

Rach’s loose panties slid past her shapely ass when she swam and she left them there until she reached the far end of the pool. Cheeky. Though she pulled them up after flipping around, they quickly slid down and exposed her sexy ass again. She dared to flip to a backstroke so her dark bush and plump labia briefly came into view. When either of them dived in, their panties or briefs came off and they were slow to find them and cover up, though they stayed under water to do so. Naked though covered in water was still provocative. We saw ourselves doing the same or more if we were the hosts. The reversal was interesting.

By day’s end they invited us for a night time grilling and hot tubbing a week later and hinted they always went in nude.

Sue and I brought swimsuits in a bag, but we each wore T-shirts and running shorts. When Rob answered the door, it was obvious he was high on something. His speech was slow, yet not slurred; his eyes were glazed. With no scent of booze, but the sweet scent of weed, we had no doubt what his source was. I kissed Rach’s cheek and our hug lingered a bit.

Rob kissed Sue on the lips for the first time. Then, with the door still open, he grabbed her T-shirt hem and teased lifting it, saying, “I don’t thinnnk you’ll need this today.” Sue took it as a joke and raised her arms. Rob lit up and as he said, “Your hhhusband, Stu you know, always brags about your perrrfect nipples. It’s about time you showed us,” he pulled her shirt over her head. She gasped, her tiny tits bounced, and her nipples changed from soft to tall, dense, and perfect. Surprised and embarrassed, yet pleased to flash our friends without fault, she stared open-mouthed at him and put her hands on her hips as she pulled her shorts tighter. When the seam of her shorts dug deep into her slit, it split her swelling labia into an obvious and lusty camel toe.

Rach laughed and fixated. I said, “I think we need to catch up with my wife’s tits.” As Sue stared, I tossed our bag of swimsuits aside, then lifted Rach’s shirt over her big tits and slid it and her loosened bra over her head. I turned her so I could see her tits and my wife’s, but Rob had one in his hand and the other in his mouth. Sue didn’t object. Her eyes closed and she threw her head back as he delicately chewed on her tasty nipple. When I leaned into Rach’s succulent tits and sucked her stiffening nipples, I saw Rob’s hands slide down Sue’s back and abs.

With just the slightest pause, he pushed her shorts down to her feet saying, “We don’t need this either aaany more.” Being commando, Sue’s trimmed muff sprung out first followed by her already swollen clit and finally her puffy pussy with a bit of inner labia pushing out like a tiny tongue ready to lick back. She gasped and stared wide-eyed, yet didn’t object or cover up. Rob knelt and licked her pussy as he extracted her feet. Pushing her legs apart, he brazenly licked and sucked her little tongue.

Rach snorted then latched onto my obvious cock pushing out my shorts. “I see you’re enjoying watching my husband eat your wife. Are you commando too?” She lifted the tented leg of my shorts until my cock and balls spilled out. “Hmm, I see you are. Me too.” Then she pushed my shorts over my stiffness. As I stepped out of them, I removed my shirt and was as totally naked as my wife. Rach dropped her shorts and revealed her recently waxed swollen pussy. I cupped her steamy mound as she said, “Sue, since my husband is busy fingering and eating you, help him strip.” His shirt was easy.

Sue’s chest, tits, neck and face were turning deeper red as she approached orgasm. Rob turned her in profile to us so we could see his long thin cock sticking out of his shorts and rubbing her calf as his hand wrapped around her cute bare ass. He pet it, then ran two fingers up her spread legs and into her ass crack. We watched as he rubbed her star hole, wet his finger in her slippery pussy, and slid it into her welcoming anus. As soon as he pushed it fully in her — with two fingers in her wet pussy and his tongue on her clit — she exploded loudly in a full-body shuddering orgasm. He eased her to the floor and whispered, “Nowww that’s how to start our evening. Everybody ready for the hot tub?”
