You two girls are members of a swim team and you are like BFFs. You share every thought with each other and you stimulate each other sexually from time to time. The guy is your coach. He is a nice guy, not a macho. You girls have a friendly relationship with him. He secretly admires both of you but is to shy to make a move. You girls are sitting on the bed together after swim training. You wear some workout clothes, perhaps leggings and t-shirts or sports bras if you have. You are talking and Margarita just finished to braid Marinas hair into a braided tail. The Coach comes in. He wears some easy to pull down pants like sweatpants or some shorts and a t-shirt. He has exciting news. The girls did so well at the last swimming competition, now they will be going to the national championship. As a reward for these great results he got them new swimsuits. The girls are happy about the news and the swimsuits. They want to try them on just right now. The coach wants to go but the girls say, stay with us, we celebrate together. So he stays. The girls are helping each other to slowly strip down their clothes and put on the swimsuits. They help each other to ajust the swimsuit to the perfect fit. They show each other their back and ask how their butts look. Then they both turn thir butt towards the coach and ask him how it looks. He is a bit shy and says what he sees looks great. They are still on the bed kneeling. Now they start teasing him by getting close to each other, rubbing their bodies in their swimsuits together, hugging. They start touching each other on the belly and hips first, then caress the tits through the fabric of the swimsuits. They gently touch each others pussy. The coach still watches and rubs his penis. The girls realize and suddenly stop. They invite him to celebrate with them. So he sits down between them and the girls kneeling each on one side of him. From both sides they lean in and come closer so theirs tits are rubbing against his head. He lays his arms around them and starts touching them each with one hand. Then he lays down on his back and watches the girls continue touching each other like over his body. Then Marina takes coaches hand and guides it to her pussy so he can touch and caress her. Margarita rubs her own pussy and watched coach caressing Marina. Then Margarita slowly pulls down coaches pants and grabs and strokes his penis. Then starts sucking his dick. Marina watches while coach still fingers her pussy. Then Marina comes loser with her head to the penis. She careses his crotch and then she takes over the sucking. The coach begins to caress Margarita and her pussy now. He slightly puss her near his head so he can lick her pussy. Margarita kneels over his head like face sitting so coach can lick her pussy. Marina then stops sucking and also kneels over the coaches lap. She pulls aside her swimsuit and begins riding his dick. Then they change positions. Margarita laying on her back, Marina kneeling next to her head so Margarita can touch/rub her pussy. The coach kneels between Margaritas legs, holds them apart. he pulls the swimsuit aside and fucks her pussy. Marina then lays next to Margarita and the girls caress each other.. When the coach is ready to cum he pulls out his cock and cums on Margeritas swimsuit. He lays down between the girls and they are all happy and cuddle.
