My childhood friend straddles me, stopping at 0.1cm of penetration, leaving her in a suspended, squat position! Her thighs quiver as she maintains this agonizing tease! This all started because... Since childhood, my friend has always been tomboyish and outgoing, while I've been a cautious virgin who hasn't even had sex with her yet. She teases me, saying, "Aren't we even dating yet?" and then dares me, "Want to practice with me?" At first, I thought she was joking, but somehow we ended up doing it... But when it came time to actually insert, I hesitated and said, "Hold on a second!" However, my friend straddles me in a suspended squat position, her thighs trembling. Finally, unable to hold back any longer, I thrust in!
