Rino teaches Asuka the technique to please a man! First, Rino demonstrated how to kiss, lick nipples, give handjobs, and give blowjobs. Next, Rino demonstrates the cowgirl position, sliding the erect cock into her pussy with expert hands and rocking her hips up and down. Next, it was Asuka's turn, and the erect penis easily entered the vagina, moving her hips up and down and rubbing the penis, which was fun to watch. Rino's positions are doggy style, side-lying and missionary, and after the man ejaculates, his penis penetrates Asuka, who also receives a heavy blow from behind, causing her to moan, and the man ejaculates again. The technology transfer is already very complete.
