In this XXX game, you need to correctly strip and seduce Akina in order to fuck her. Problem is, she loves to give blowjobs, and will periodically grab your dick and start sucking. If you blow your load before you get to fuck her, you "lose" (Is it really losing though?). You need to strip her, and play with her a little before she will allow you to go further.
Tips : Click on the stars in order to move her / undress items of clothing, Clothes need to be removed in some resemblance of an order (panties must be last). You also need to please her using the hand and the tongue tools in order for her to be aroused enough to "allow" you to strip and fuck her. Just don't forget about the shoes!
