Traveling with a mobile tent to various universities, we approach modern female college students under the guise of a late-night show that listens to sexual concerns. Our goal is to completely conquer all 137 universities in Tokyo!!!■ Report ① This time, we visited M University, known for nurturing and developing students' individuality! It's said that there are many reserved, quiet, and diligent girls with high academic motivation. So, what about the sexual situations of these serious girls...!?② As expected, this university is famous for having many serious girls. Even when we approach them, they rarely stop. Every girl is so composed!③ Finally, we were able to talk to Riko-chan, a clean-cut type. She's a third-year student in the foreign languages department.④ Riko-chan hasn't had a boyfriend since entering university. She's so cute, why...!? It turns out she's not really interested in people. She says she goes home right after social gatherings. She's definitely a strong girl!⑤ While chatting, I kept noticing her obviously large breasts. They're G-cup!! They're indeed full.⑥ Skillfully guiding the conversation, we started the sex position lesson. Although a bit confused, Riko-chan also seemed happy. Serious girls really do like dirty things. When I pressed an electric massager on her panties, she was frantically unable to move, clearly feeling pleasure! Directly stimulating her vagina made her hips spasm and reach orgasm. Confirming that the switch had been fully turned on, I ruthlessly groped her G-cup breasts from behind. The touch was incredibly soft. These are truly national treasure-level breasts～⑦ Using a toy to simultaneously stimulate her vagina and clitoris, when I took out my penis she eagerly sucked and licked it. From behind, her vagina was already soaked.⑧ Of course, I also had her do G-cup tit-fucking! Riko-chan seriously and happily performed the tit-fuck. She seems to enjoy serving others. Serious girls are serious even in sex life.⑨ With cowgirl position penetration, the sound of "slap slap" rhythm and "squish squish" water sounds overflowed from her soaked vagina, causing her body to spasm and cum multiple times. Midway through, I also enjoyed her G-cup breasts, and had sex using the positions I taught earlier♪ Finally, I finished by shooting a large amount of semen onto her fair, soft skin...! Serious girl Riko-chan also enjoyed the sex and went home with a smile♪♪
