Emerging from the pool, Alex and Stela, siblings bound by more than blood, share a towel, their bodies glistening with water and unspoken tension. Stela's nipples harden, visible through her wet top, as Alex's swim trunks do little to conceal his growing excitement. They retreat to their shared room, leaving a trail of wet footprints. Stela, feigning innocence, drops her towel, revealing her naked form. Alex, unable to resist, strokes his hard cock, watching Stela's fingers dance over her clit. They come together, a tangle of limbs and wet skin, their bodies slapping together as Alex pounds Stela's tight pussy against the wall.
