It was a raucous party for girls. Girls were chasing each other with squirt guns and lost their bikinis in the crowded pool. Everywhere, tits were jumping. Eveline and Valentina decided they needed a break. Lesbian sex without penetration should be less enjoyable than what Mia brought with her, a lovely pink strap. Valentina was first fucking, or strapping, Eveline in the dog. Subsequently, Eveline rode Valentina, and last but not least, Eveline strapped Valentina. All until they reached a screaming orgasm.
