"Even though I didn't touch the nipples! This is too intense!!" Aika Yumeno, unable to hide her surprise at the premature ejaculation of B.B. Boys whose nipples are erogenous zones. "What would happen if I played with the nipples while inserting?" Ticklish! Ticklish! Followed by nipple-pinching handjob leading to a triple ejaculation, or during a BBQ, pinching nipples and then immediately in the tent, ticklish! Followed by a nipple-twisting riding position, showing a free-spirited nature! Teasing nipples with such a smile is unfair!!
