Women Knocked Unconscious by Sex With Well Endowed Guys

A boyfriend who’s too much for me to handle, but too good to give away to someone else. He’s so much better than my boyfriend that I’m going crazy with pleasure!

Due to a sudden job transfer, Ye-seo ends up staying at her older sister Ye-jin’s house. Ye-jin finds the unexpected arrangement of living with her younger sister bothersome. One night, Ye-seo wakes up to get some water and accidentally witnesses Ye-jin having sex with her boyfriend, Kyung-soo. She finds herself attracted to him. Meanwhile, Ye-jin is troubled because she and Kyung-soo are sexually incompatible. When Ye-seo’s boyfriend, Su-cheol, comes over to fix a light, Ye-jin takes the opportunity to seduce him, and they end up having sex. Satisfied with her sexual experience with Su-cheol, Ye-jin encourages Ye-seo to have sex with Kyung-soo. Since Ye-seo is already attracted to him, she makes an excuse related to work to invite him over, and they end up having sex. Ye-seo discovers that she enjoys sex with Kyung-soo much more than with her own boyfriend, Su-cheol. Ye-jin is satisfied with Su-cheol’s considerate, gentle, and attentive lovemaking, while Ye-seo prefers Kyung-soo’s rough, masculine style of sex. Realizing that they are more sexually compatible with each other’s boyfriends, the two women decide to swap sexual partners.
