Hard to imagine that something that starts with sitting cross-legged could be so hot, but trust. Have him sit cross-legged on the bed, and straddle him, using his raised thighs to support your butt so he doesn’t go too deep. You control the thrusts (control = good): go slow and rock back and forth, letting him slowly in deeper. Also good for deep, hot kisses, plus you’ll have a free hand for self-love on your cl!t.
