I'd have her slowly envelop my cock. All the way from the tip, down to the base. My balls touching her cheeks. Then the goal is to not move. Only cockwarming. No clenching. No twitching. No thrusting of the hips. Just sit there, being full, the urge to start moving slowly driving us mad. We'd sit like that for an hour, fighting our own lust, while watching porn. Porn with bouncing tits and asses, people who fuck aggressively, primally, and girls getting creampies. We'd watch people fuck in all the ways that we couldn't. And if she accidentally contracts her muscles, or moves, because she just can't help herself I would smack her ass hard as punishment. The goal is to be driven insane. Precum leaking from the tip inside her cunt. Mixing with her juices. Slowly leaking down the shaft, onto my balls, covering the bedsheet.
