SDMUA-045 - My girlfriend thinks I'm a virgin, but her bustier sister seduced me into endless sex.

The second SOD exclusive release for F-cup actress Erika Inami, known for her marshmallow breasts. It's an NTR drama that fully unleashes the 'creampie' that was sealed in her previous work. The protagonist, Mamoru, is a college student in a platonic relationship with his shy, A-cup girlfriend who has a 'small-breast complex.' As a 'virgin couple,' they never go beyond kissing in bed. Wanting to deepen his relationship with his girlfriend, Mamoru takes on a tutoring job for her high schooler sister, Erika (Erika Inami), who has large breasts. On a Monday when the older sister is away, Erika seduces the protagonist while wearing a uniform with no bra (see jacket cover). "Teacher, touch them." Unlike his girlfriend, Mamoru is curious about sex and decides to lose his virginity to 'his girlfriend's sister.' "Um... is it here?" "No, that's my butt hole." He manages to insert his erect penis in the missionary position, but ejaculates within seconds (zero thrusts). After a 'fellatio -> re-erection' sequence, he finally loses his virginity on the second attempt. Hooked on training the 'former virgin,' Erika demands 'raw insertion' without a condom as the 'next step.' Wanting to avoid pregnancy, Mamoru suggests a compromise of 'raw insertion -> withdrawal' (though the pregnancy rate for withdrawal is actually over 20%). Completely captivated by the big-breasted sister, the protagonist even brushes off advances from his now-willing girlfriend with a "maybe next time." By the summer of that year, their relationship evolves from 'withdrawal' to 'creampie' (Erika's look also shifts to a more 'gyaru' style). "Will you really date me properly?" "Yeah." "I love you, teacher." It's a well-crafted production that features a '(fake) ending' for losing his virginity, followed by a 'true ending' after stealing the protagonist away. The 'wicked smile -> continuous creampie' right after the sister witnesses (or is made to witness) the affair is truly excellent.

*Erika's devilish performance of seducing her sister's boyfriend and gradually making him fall in love with her was great! I'm completely captivated by Erika, too! Anyway, her smile is cute, and she has big breasts and a loli body, and the uniform looks great on her! The uniform play is very exciting and moe, and there is also a uniform version of the older sister, so you can enjoy it in different situations. There was a lot of entanglement throughout, and the sex that attacked the very edge of not getting caught was exciting! (Even though you'll find out at the end lol) I ended up winning over Erika who played the role of a little devil!
