At this point, Michael couldn't care less about anything else. Unless Betty woke up, even if the sky fell, it wouldn't bother him. He slowly lay down on his side, facing the same direction as Betty, but his position was much lower than hers.
Betty was on the upper side of the bed, and Michael in the middle, which meant that Michael's face wasn't facing Betty's back or hair, but rather her buttocks and the crevice between them.
Due to Betty curling up her legs, from behind, the way Betty's buttocks were raised, Michael could touch Betty's most private parts—the vagina and anus.
Michael seemed in no rush; he wanted to savor the moment, to fully imprint every detail in his mind, including the visual, olfactory, and taste sensations.
Michael's face slowly moved closer to Betty's buttock crevice, and Betty gradually felt the warmth of Michael's breath. His breath continuously hit her crevice, stimulating her most sensitive areas.
