This position allowed for deep penetration, and because both of them were almost suspended, the force of gravity with each thrust sent Ryan's cock plunging all the way in, as if Olivia's uterus was slamming against his glans from above.
The girl, who had just orgasmed, was already hypersensitive. The deep thrusts made her feel as if she were melting from pleasure. The once pure and beautiful girl couldn't help but lean her head on Ryan's shoulder, moaning softly as she raised her rosy buttocks, matching his rhythm.
With every thrust, gravity ensured that Ryan's glans scraped and rubbed against Olivia's sensitive cervix, almost violently. His entire length was buried deep inside her, hitting her cervix again and again.
