Lara and Olivia, step-sisters, are hosting their friend Eeona at home for a sleepover. Olivia is laying on the sofa with her tummy down; Lara and Eeona come in and ask her if she can help them with a school project where they tickle her feet to record her reactions and sensitivity level. So Lara sits on her legs and Eeona sits on the floor, and they start to tickle her soles with their fingers, checking different areas and writing down in their journal how ticklish it is from 1 to 10. After a few minutes doing this, Lara is getting turned on and Eeona too; as Eeona keeps tickling Olivia's feet slowly while licking her lips and looking at Lara in a lustful way, she starts caressing Lara's breasts on top of her shirt first, and then puts her hand under her shirt. They start caressing their breastx while tickling Olivia's feet and kissing. Olivia figures out that they are not doing the project for school when Eeona by accident starts licking Olivia's feet, and Lara confesses Olivia that she has a tickling fetish; so Olivia asks her if she wants to tickle her but in exchange they have to be tickled too. So they agree.  Eeona is naked on the bed tied up in a spread eagle position. Olivia and Lara start caressing her breasts and nipples, tickling and sensually stimulating her while they also kiss; then they start tickling her sides and armpits while also licking her nipples a bit. This makes Eeona laugh. Olivia teaches her step-sister how to tickle and at the same time how to stimulate Eeona so she gets more aroused and more ticklish. Lara then moves to the feet, starting to tickle them slowly while Olivia kisses Eeona and then starts playing with her pussy gently using her fingers, while also kissing her nipples, then she starts using the vibrator on Eeona's crotch. They tickle and tease Eeona for a few minutes making her close to orgasm, but this just makes her more ticklish. Olivia then moves to Eeona's feet too; while kissing her step-sister, confessing her that she loves tickling feet and starts tickling and licking them too. Lara confesses Olivia that she likes to tickle feet too and she gets horny when she hears Eeona laugh and beg; so she keeps tickling and licking Eeona, also using the electric toothbrush while Olivia sits behind her and touches her breasts and pussy, and kisses her neck and ears telling her to tease Eeona more. Eeona laughs and begs them to stop as they find the most ticklish spot on her feet, so Olivia keeps masturbating Lara's crotch, but at the same time she also tickles Eeona's feet, which makes her crazy, and Lara comes to orgasm hearing Eeona begging and laughing.  Lara finds herself tie to the bed in the same manner as Eeona has recently been. Eeona moves to Lara's feet, starting tickling and licking them while Olivia kisses Lara and then starts masturbating her pussy, using her fingers on the lips first, then she starts to caress inside her lips and on the clitoris while also kissing her nipples. They tickle and tease Lara for a few minutes making her get close to the orgasm, but this just makes her more ticklish. Olivia then move to Lara's feet too; while kissing Eeona, confessing her that she loves tickling feet and starts tickling and licking them too. Eeona confesses Olivia that she likes to tickle feet too and she gets horny when she hears Lara laugh and beg; so she keeps tickling and licking Lara while touching her breasts and pussy. Olivia kisses her neck and ears telling her to tease Lara more, then starts playing with her nipples while also tickling Lara's feet. Lara laughs and begs them to stop as they explore the most ticklish spot on her feet.  Olivia is very horny and starts masturbating and at the same time tickling Lara's feet, which drives her crazy, and Olivia cums hearing Lara begging and laughing.  Now Olivia is tied to the bed; she is very horny and sensitive, and Lara is still very horny, so she is determined to tease her step-sister for good. She sets up a videocamera to record the scene, and starts kissing Eeona, and together they start tickling Olivia's upperbody, moving from her breasts to her sides and armpits while they kiss; which makes Olivia beg immediately, as she is super sensitive. They both begin to kiss her nipples and tickle at the same time her sides and armpits, teasing her for how ticklish she is, and Lara tells her that she has been dreaming so many times to be able to tickle her like this; while Eeona is also getting horny now; as Lara is touching her now and she was teased before when she was tickled, so she also wants to have the orgasm and can't resist anymore hearing Olivia laughing and begging. So they both start moving to Olivia's feet tickling and licking them, while she laughs more and more; and Eeona is getting more and more horny while Lara is touching her breasts and Eeona is masturbating her pussy. They both kiss and tickle and lick Olivia's feet, while also looking at the camera as Lara is recording everything. Eeona cannot r
