Straight-laced Virgin Boyfriend's Oversized XXX ~Will this even fit...?~

A serious, brainy couple melting into pleasure, their minds going blank as they devour each other in sex... It's very, very lewd! She is confused by the out-of-spec size, but faces it head-on. It seems their physical compatibility is excellent, so there's no pain or sense of being forced. Changing positions again and again, with her even actively straddling him—it's the first night of sex for a couple on a hot spring trip, seeking each other over and over. I think this is a highly humid work with a strong impression of heat and instinct. Men and women in heat are so erotic...!

Chisato is losing patience with her serious boyfriend Keitaro and their chaste relationship. When she agrees to sex, she pushes him aggressively, and he reveals his massive size and the trauma of his past sexual failures. It's so admirable how she tries her best to perform oral on a member she can't even fit in her mouth and puts a condom on him. The tragedy of her getting used to the pressure and feeling confident, only to realize only half was inserted (lol). He reaches her depths and ejaculates, and Chisato, excited by his arousal and her own fluids, gets pinned down from behind and can't escape—is she dying? But she gets hooked, and by the third time, she's on top, inserting him herself and riding him—bravo. The massive size and stamina that keep going after that are terrifying. The art is pretty, but despite the white-line censorship, it doesn't feel very realistic. Since 80% of it is sex, it's quite a satisfying read.

It's been 3 months of a pure relationship with my serious and stiff boyfriend. During our hot spring trip, I finally worked up the courage to invite him to have sex for the first time, and I couldn't help but chuckle at how stiff and formal his response was, just like someone who studied law lol. When it came time for the deed, a massive, never-before-seen thing appeared before my eyes. It was truly huge and long. So that's why he wasn't interested in sex and was a virgin!!! But since he gathered his courage, the heroine decides to commit. She can't even fit it in her mouth because it's too big, and her jaw feels like it's going to dislocate. Just when she thinks she's getting used to the penetration, she realizes only half is in. The heroine's head and body go completely blank once it's all the way in. Her dazed expression was so erotic. Seeing her climax, his reason snaps, and they end up devouring each other like beasts. This is exactly how a couple's hot spring trip should be! I thought getting turned on by seeing his impressive morning wood after doing it so much was also a highlight(?) of the trip lol. Thank you for the wonderful work.
