Buying a holiday bikini is always a difficult and confusing choice. After visiting all the stores in town my partner and her two daughters aged sixteen and eighteen, ended up buying one from every outlet, and so consequently they ended up with half a dozen each. They packed them all with their beach essentials into one suitcase for convenience.

After a chaotic flight to our island in the sun, we finally made it to the apartment we were to share in the all-inclusive resort.

When they came to unpack, it was like a free-for-all all trying to work out whose was whose. They ranged in sizes from UK 8 -12 in varying degrees of very skimpy to a high-thigh one-piece, in a rainbow of colours and shimmering materials. This obviously made for some confusion, so much so that they ended up wearing each other’s whether they fitted or not.

We all went out to explore the resort. Pam and I installed ourselves on sun loungers by the pool, while the girls went to the beach wearing their most revealing looks.

Later when they returned to the apartment, (after no doubt being hit on by all the local lads), bikinis were flung in a pile on the bathroom floor in various degrees of wetness. One pair of Brazilian-style tie-sided pink bikini bottoms had obviously never been in the sea, but a wet patch all over the crotch betrayed its wearer’s arousal, at what, I could only guess. Someone had had a dramatic effect on her libido, it would seem.

I couldn’t resist picking them up and feeling the slippery wet juices on the iridescent pink material, so recently in contact with someone’s fanny. I couldn’t stop myself from inhaling the sweet scent of arousal.

Pam was having a Siesta as we did in the afternoon, and this was a cue for a sex session between us. She was naked as it was so hot, but I prefer her in panties, or even better, or so I thought, in her daughter’s pink bikini.

“Darling, I was really looking forward to some bikini sex. Why don’t you put it back on?”

“It’s all wet, but if you must, just get one from the pile.”

This was a random game, she didn’t seem bothered about which pair, but I was. Pam was happy to let me choose, as I often got to pick her panties from her fine selection before sex. Maybe she just forgot they were all mixed up with her daughter’s.

The girls were back out at the beach so I went to the bathroom and picked up the tempting used pink bottoms from the bathroom floor, and figuring Pam would never guess, brought them back to our bedroom.

Pam was lying face down on the bed, her naked rounded bottom half covered. My plan was to make her wet with my fingers before pulling the wet pink bikini pants up her tanned thighs so she wouldn’t notice how soaked at the crotch they were.

To my surprise, I found she was already wet down there so my fingers slipped in easily. I jumped the gun and pulled the bikini bottoms up her legs drawing them up over her ample rear, a bit of a stretch, I must say. I was struggling to make them fit her.

“These are a bit tight, are you sure you’ve got the right ones?”

“Yeah, I wanna see your ass, beach babe”

She laughed, “Here it is then.”

Pammy wriggled her hips, helping me to ease the tight bikini pants up over her behind and snug into her cunny.
This was a sight that almost made me cream my Speedos. The thin wet strip of hot pink fabric disappeared between her open lips, the Brazilian cut riding up over her arse.

I cupped her cunny feeling the mingling of juices with her own heady arousal. As I buried my face between her arse cheeks I inhaled the horny perfume of two hot sexes. I began to lick her through the slick material and could taste the combined scent of both mother and daughter.

I pushed past the crotch and inserted my tongue along into her cunt, now soaking with arousal. As I found her clit now pushing into the fabric she ground herself into my face and squished her fanny into her daughter’s bikini bottoms. I pulled the tie sides higher up her hips and she began to buck into my face. I could feel how turned on she was by the tight fabric. Flipping my raging hard-on out of my Speedo’s, now stained by my own leaking pre-cum, I pulled the sodden strip of pink material aside and plunged my cock straight up her hungry cunt, and began fucking her with mounting urgency.

The sight of her up-thrust rear outlined by the too small borrowed bottoms that had so recently been shaping her daughter, made the spunk churn in my balls. Overcome with the sight of her and the implications, I pulled out at the last moment and sprayed streaks of come all over her arse and the remains of the pink bikini. She let me do it, even reaching between her legs to frig herself to her own mounting climax. I had ruined the bikini but she didn’t care and mindlessly pursued her own orgasm explosion. Her cunt fluids were coming in little spurts out through the material. the scent of mingled sex was intoxicating.

As she rolled over afterward, gazing down at the mess, she seemed surprised.

“Oh, these definitely aren’t mine you know! You’d better go wash them out.”

I had other plans, and easing them off over her thighs, dropped them in the laundry bag in the bathroom where I could find them later. Strangely when I did go to look for them again when everyone was out at the beach, they were gone.
