My adult childhood friend straddles me and lowers herself just 0.1 cm onto my cock, then freezes in a trembling squat. She has always been active and blunt, while I am a cautious virgin who still has not slept with my girlfriend. After teasing me about it, she offers to let me practice with her. We get carried into sex, but the moment penetration begins, I lose my nerve and ask her to wait. Still hovering over me with her thighs shaking, she finally reaches her limit and drops down, taking my cock all the way inside.
