Well, I went to the actress' DMM page to see if any lesbian covers popped out, but I then got intimidated over the multiple number of pages. So I got the bright idea of searching for her English name (as well as both variations of the name in Japanese, 吉沢明歩[よしざわあきほ]) at the "Slimedog's Lesbian" thread. Esteemed Member Savajex (what a giant loss for Akiba-Online that she is no longer participating) was the only one who mentioned the actress (and I remembered this interesting exchange, regarding how hetero women can make the gay switch so easily, whereas hetero men are a totally different story), with the strong implication that Akiho Yoshizawa has never explored vaginas. (At least not up until early 2014.)
They have done three AVs SOE878, SOE695, and SOE491. Akiho never really 'touches' Yuma in the movies. However, Yuma in another videos licks and sucks Rio(Tina Yuzuki) tits in AVGL109.
That I remember in SOE-491 they only did 3some FFM ? SOE-878 and SOE-695 are more interesting for me, because they did little orgy 4some FFMM
Unfortunately S1 rare to make this kind JAV, would be interesting if Mihiro and Rin Suzuka participate in 4some too, but its never happened and Rina Rukawa only did 1 in SNIS-173
